didericis-claude e33cccfdde fix(db): close SQLite connections explicitly to suppress ResourceWarning on Python 3.13

`sqlite3.Connection.__exit__` only commits/rolls back a transaction — it
does not close the connection. Python 3.13 (the Nix env on the KVM
runner) emits `ResourceWarning: unclosed database` for every connection
GC'd without an explicit close, producing noisy output in the coverage job.

Add `DbStore._connection()`, a `contextmanager` that calls `self._connect()`,
wraps it in the existing transaction context manager, and closes the
connection in a `finally` block. Change all `with self._connect() as conn:`
call sites in `db_store.py`, `audit_store.py`, `queue_store.py`, and
`orchestrator/registry.py` to `with self._connection() as conn:`.
`_connect()` remains as the per-subclass hook (RegistryStore overrides
it to set `busy_timeout`); `_connection()` delegates to `self._connect()` so
the override is respected.

didericis 319cac85b8 ci: drop dev-requirements pip install on the self-hosted KVM runner
test / coverage (pull_request) Has started running
test / integration-firecracker (pull_request) Successful in 12s
test / integration-docker (pull_request) Successful in 28s
test / unit (pull_request) Successful in 37s
The self-hosted runner's Nix python env has no `pip` module, so
`python3 -m pip install -r requirements-dev.txt` failed with "No module
named pip" in both firecracker jobs. Neither job needs that install:

- integration-firecracker runs the stdlib `unittest` suite (no deps);
- coverage needs only `coverage`, which the runner's Nix python env
  already ships (7.12.0) — verified `coverage run`/`coverage json` work.

pylint/pyright are lint.yml's concern, not test.yml's. The ubuntu-latest
`unit` job keeps its `--break-system-packages` install unchanged.

didericis 5b359fe8d2 fix(git-gate): scan $new --not --all for every push, not $old..$new

test / integration (push) Successful in 31s
lint / lint (push) Successful in 43s
Update Quality Badges / update-badges (push) Successful in 38s
test / coverage (push) Successful in 40s
The pre-receive hook scanned existing-branch updates with the delta range
$old..$new. On a rebase / non-fast-forward force-push onto an advanced main,
$old is no longer an ancestor of $new, so $old..$new expands to all of main's
new history — including the deliberate sandbox-escape gitleaks fixtures — and
the push is rejected on commits that belong to main, not the branch.

Unify the range on `$new --not --all` for every non-delete push (this is the
deferred open question from PRD 0028, which already applied it to new refs
for #106). It scans only the commits the push introduces and is
security-equivalent: the bare repo's refs come only from trusted upstream
mirror-fetch and gitleaks-gated pushes, so an excluded commit is
already-upstream or already-scanned. It is also more correct for
non-fast-forward pushes, where $old..$new can skip commits off the direct path.

Fixes #421

`backend setup/status/teardown` manage host prerequisites only and never
open the store, but the CLI dispatcher ran the schema-migration gate before
every command. On a non-TTY runner the gate's `Migrate now? [y/N]` prompt
reads EOF and refuses, so `backend status --backend=firecracker` exits 1 —
breaking the Firecracker CI preflight on any host without a pre-migrated DB.

Exempt `backend` from the gate; store-touching commands stay gated.

Fixes #419

didericis-claude 4302678f3e docs(research): expand sandbox landscape with 6 new tools; add agent-tailored policy axis
tracker-policy-pr / check-pr (pull_request) Failing after 6s
Isolation tools added: Cleanroom (Buildkite), container-use (Dagger),
Docker sbx, Anthropic srt.

Governance/pre-action layers added as a separate section: Microsoft
Agent Governance Toolkit (per-agent DID + YAML policy + trust score),
Open Agent Passport (declarative policy + cryptographic audit).

Comparison table: 14 → 14 columns; new Agent-tailored policy row added.
Second addendum covers competitive position on role-tailoring, Docker
sbx as new DX-class competitor, and borrowable ideas (trust-score decay,
live network TUI, cryptographic audit chain).

Discourse note: adds Per-agent role tailoring to "What it covers well"
with competitive comparison table across 9 tools.

didericis-claude ed38c68b01 test(integration): lift GITEA_ACTIONS skip for Firecracker backend
The sandbox-escape test was unconditionally skipped when GITEA_ACTIONS=true,
which prevented Firecracker orchestration coverage from being measured even
when BOT_BOTTLE_BACKEND=firecracker is set on the KVM runner.

Narrow the skip to: GITEA_ACTIONS=true AND BOT_BOTTLE_BACKEND != firecracker.
When BOT_BOTTLE_BACKEND=firecracker the test is explicitly opted in to run on
the self-hosted KVM runner where the required /dev/kvm + TAP pool exist.

didericis-claude df24e5e955 ci(coverage): address review findings from PR #349
- Finding 1: set BOT_BOTTLE_BACKEND=firecracker on the coverage step so
  the integration suite actually exercises the Firecracker orchestration
  paths rather than defaulting to Docker
- Finding 2: restrict the coverage job to push+workflow_dispatch only;
  PR-controlled code no longer executes on the privileged KVM runner
  automatically — maintainers trigger workflow_dispatch for trusted PRs
- Finding 3: expand path filters to include workflow files, scripts, and
  README so changes to CI configuration trigger the workflow itself

didericis-claude ea147edb6f ci(coverage): install dev requirements on the KVM runner
The self-hosted KVM runner is a persistent machine, so
--break-system-packages is inappropriate. Use --user instead so
coverage (and pyright/pylint for future jobs) land in ~/.local
and survive between runs without touching the system Python.

didericis 2b4382bce9 ci(coverage): run the diff-coverage gate on a self-hosted KVM runner
Re-land the coverage gate deferred from #343. The Firecracker VM/SSH
orchestration (~230 lines) is only exercised by the integration suite,
which needs /dev/kvm + the provisioned TAP/nft pool — a container runner
skips it and those lines read uncovered, so the 90% diff gate can't pass
on ubuntu-latest. Move the `coverage` job to a self-hosted `kvm` runner
with a firecracker-readiness preflight (binary + /dev/kvm + `backend
status`) so the integration test actually runs. Unit/lint stay on
ubuntu-latest. README documents the runner prerequisites.

Depends on a registered self-hosted runner labelled `kvm`; until one is
provisioned this gate will not run. See PRD 0069 / #348.

tracker-policy-pr / check-pr (pull_request) Successful in 4s
Gitea Actions reports skipped jobs as a non-success status, which caused
label-issue to block PRs even though its if-condition correctly excluded it.
Two dedicated workflows eliminate the skipped-job problem entirely.

`tracker-policy / check-pr` to `tracker-policy-pr / check-pr`.

didericis-claude 727eafe0f9 docs(research): clarify prompt injection framing and blast-radius risks
Collapse "trusted-channel data injection" into prompt injection
throughout — the trusted channel is a delivery vector, not a distinct
attack class. Add explicit inbound/outbound orthogonality framing.
Replace the two redundant "weaker" bullets with a single prompt
injection section and a new blast-radius breakdown covering work
product corruption, malicious commits past gitleaks, exfiltration
through allowlisted channels, and dependency-install injection.

didericis aa44feea02 docs(research): note on malicious-commit scanning at the git-gate + paid-feature analysis
Adds a research note on whether/how to scan for malicious code (not just
secrets) in commits pushed through the git-gate, and whether the semantic
(LLM) layer is a defensible paid feature.

Verdict: no scanner reliably detects malicious code (undecidable +
adversarial), so the frame is raise-cost + cover-the-obvious + human-gate
the dangerous. Ranked layers: dependency/supply-chain scanning (Socket/OSV/
GuardDog) > heuristic/obfuscation (Semgrep-on-diff) > risk-based human
gating via the existing supervise plane > best-effort LLM diff-review.
Fast scanners inline in the synchronous pre-receive; heavy analysis async.

Monetization: the paid unit is the governed git-egress review bundle
(managed semantic review + web-console human-review flow + RBAC + audit +
cross-run policy), not the raw scanner — which stays OSS like gitleaks.
Extends the egress audit+custody wedge to code artifacts; the supervise
console generalizes across all proposal types (egress, gitleaks, commit
review). Sell the workflow, not the detector's accuracy.

didericis f2e2572a40 docs(research): add DX axis — "run Claude yolo-style" — to the sandbox landscape
Adds a "DX: run Claude yolo-style" row to the comparison table plus a note
framing developer experience as a differentiator. The field splits into
wrappers-around-the-agent (bot-bottle, agent-safehouse — one command, the
agent just runs, `--dangerously-skip-permissions` on by default with the
sandbox as the guardrail) vs libraries/services (boxlite, microsandbox,
CubeSandbox, E2B — you wire the agent in via SDK/cluster). agent-safehouse
is the only DX peer, but it's macOS-only Seatbelt with no egress story.
"As easy as native yolo, but actually sandboxed" is the defensible line.

didericis 7069fa225d docs(research): add long-running posture axis to the sandbox landscape
Adds a "Long-running posture" row to the comparison table and an addendum
note contrasting the two models: E2B and CubeSandbox are ephemeral-per-task
(5-min default timeout, tier-capped continuous runtime, duration via
pause/resume + reconnect-by-id), while bot-bottle bottles are persistent,
named, and supervised by default. For agents that run for hours/days this
posture difference matters more than the isolation primitive.

didericis aa224c4381 docs(research): add CubeSandbox to the sandbox landscape; fix stale bot-bottle self-description
Adds CubeSandbox (Tencent Cloud, Apache 2.0, RustVMM/KVM microVM) to the
agent-sandbox landscape survey: per-project note, comparison-table column,
and a dated addendum on what it means for positioning. CubeSandbox is the
first surveyed project to bundle a connection-level egress allowlist +
audit + in-flight credential custody, but it does NOT do content DLP on
authorized channels — that plus the orchestration layer is where
bot-bottle stays distinctive.

Also corrects two stale self-descriptions the survey (2026-05-11) baked
in and I'd propagated:
- Default isolation is now a VM per bottle (Firecracker microVM on KVM
  Linux, Apple Container on macOS); Docker is only the legacy fallback,
  per _default_backend_name(). Was described as Docker-by-default.
- Outbound DLP is bot-bottle's own mitmproxy egress scanner + gitleaks on
  git push, not pipelock (removed). All references updated; a note
  records the change.

`undefined-all-variable` fires on CommitCancelled / Freezer / get_freezer

didericis-claude 8b442b8718 perf: lazy-load backend modules and consolidate docker subprocess helpers
Importing backend.docker.util previously triggered eager loading of all
three backend packages (~76 modules) because backend/__init__.py imported
DockerBottleBackend, FirecrackerBottleBackend, and MacosContainerBottleBackend
at module scope. This made the module prohibitively expensive to import
from the orchestrator layer and elsewhere.

The three backend imports are now deferred into _get_backends(), which
loads all three on first call and caches the result in the module-level
_BACKENDS variable (initially None). Module-level __getattr__ exposes
backend classes and freeze symbols lazily for existing import/patch sites.

backend/docker/util.py raw subprocess.run(["docker", ...]) calls are
replaced with the shared run_docker primitive from docker_cmd, eliminating
the duplication between the backend and orchestrator implementations.
_silent_run() is removed; image_exists() is inlined directly onto
run_docker. The commit_container test is updated to patch run_docker
instead of subprocess.run.

didericis 5eb6c8d99b ci: drop actions/setup-python from the remaining workflows
Applies the same fix as test/lint to every workflow that still used
actions/setup-python, which the old act_runner engine mishandles:

- update-badges: was broken identically to lint — setup-python + pip
  install hit the image's externally-managed system Python. Drop
  setup-python, install with --break-system-packages, and use `python3`
  (not bare `python`) for the coverage steps.
- canaries, prd-number: no pip install, so not failing, but they carried
  the same fragile (and network-heavy) setup-python for stdlib-only work.
  Removed — the image's system Python 3.12 runs them directly.

didericis 4f10b810d4 ci(lint): drop actions/setup-python; install into the container's system Python
lint / lint (push) Successful in 2m16s
Same fix as the test workflow: the old act_runner engine mishandles
actions/setup-python's PATH, so `pip install` hit the image's
externally-managed system Python and failed with
"externally-managed-environment" on the "Install dev dependencies" step.

The runner image already ships Python 3.12 and the job container is
ephemeral, so drop setup-python and install straight into system Python
with --break-system-packages. pylint/pyright console scripts land on
/usr/local/bin (on PATH), so the lint steps still resolve. Also drops the
now-pointless `pip install --upgrade pip`.

The old act_runner engine (v0.2.13 on the delphi-ci runner) mishandles
actions/setup-python's PATH injection: pip installs coverage into the
toolcache interpreter while `python3` in later steps resolves back to the
image's system Python, so unit/coverage jobs failed with "No module named
coverage". Newer runners (TrueNAS's v0.6.1) don't, which is why it only
broke on delphi.

The runner-images/act container already ships Python 3.12, and the job
container is ephemeral, so drop setup-python entirely and install straight
into the system Python with --break-system-packages. Every step now uses
one interpreter consistently, on any runner version. Also removes the
redundant setup-python step from the integration job (stdlib-only).

mitmdump -s requires a file path, not a module. Instead of copying the
full egress_addon.py to /app/, write a one-line shim at image build time
that re-exports addons from the installed package. mitmdump finds the

Install bot_bottle via pip in Dockerfile.gateway instead of COPYing
individual .py files flat under /app/. This eliminates the try/except
import shims in egress_addon_core, dlp_detectors, egress_addon,
supervise, supervise_server, and git_http_backend that existed only
to support the flat-bundle layout.

Adds bot_bottle/constants.py as a single source of truth for
IDENTITY_HEADER and GIT_GATE_TIMEOUT_SECS, removing the duplicated
literal definitions in egress_addon.py, supervise_server.py,
git_http_backend.py, and git_gate_render.py.

Test files updated to match: test_supervise_server.py drops the
sys.path.insert hack in favour of direct package imports; the
egress_addon test shims no longer pre-populate sys.modules with a
bare egress_addon_core alias.

b1850be's fail-closed-503 test (rebased in from main) built a git-http
server with a flat repo.git and no policy_resolver. The resolver-only
data plane on this branch denies an unattributed request with 404 before
it reaches the access-hook path the test exercises, so it saw 404 != 503.

Nest the bare repo under <root>/<_BID>/ and set _FixedResolver(_BID) on
the server, matching every other test in this module, so the request is
attributed and reaches the access-hook (mocked to raise PermissionError)

didericis d0b7de119f test(egress): set orchestrator URL for entrypoint tests; cover fail-closed guard
The egress_entrypoint.sh fail-closed guard (this branch) exits 1 when
BOT_BOTTLE_ORCHESTRATOR_URL is unset, which broke the argv-construction
tests that ran the script without it. Set the URL in the shared
_run_entrypoint helper (a precondition for reaching mitmdump now, like
PATH) and add a test asserting the guard fails closed when it's absent.

didericis ea1fbeeaa0 refactor(gateway): fail closed without an orchestrator URL; drop stale single-tenant comments
Follow-ups from the #402 review of the single-tenant data-plane teardown.

- egress_entrypoint.sh: refuse to launch mitmdump when
  BOT_BOTTLE_ORCHESTRATOR_URL is unset, so the fail-closed guarantee no
  longer rests solely on mitmproxy's errorcheck addon exiting on the
  addon's load-time raise. A misconfigured gateway can never come up as
  a bare TLS-bumping open proxy with no policy.
- orchestrator/gateway.py: ensure_running() raises GatewayError on an
  empty orchestrator URL — a URL-less launch would only crash-loop the
  now-resolver-only daemons (egress raises, git-http exits 1, supervise
  exits 2). The env-injection branch is now unconditional.
- Drop stale "single-tenant" / "reads routes.yaml" comments in
  gateway.py and egress_entrypoint.sh, and the /etc/egress/routes.yaml
  layout line in Dockerfile.gateway.
- Tests: gateway fixtures supply an orchestrator URL; add a
  refuse-without-URL test and assert the URL env is injected.

didericis b601b663e2 refactor(gateway): remove the single-tenant data-plane paths (audit #400 finding 3)
All three backends (docker, firecracker, macos-container) now launch through
the consolidated orchestrator, and every production gateway sets
BOT_BOTTLE_ORCHESTRATOR_URL — so the legacy single-tenant (`resolver is None`)
branches in the shared gateway's data plane were unreachable dead code, a second
security-relevant path to keep correct in parallel with the live one. Make the
orchestrator resolver mandatory and delete the single-tenant paths from the
three data-plane modules.

egress_addon.py: drop the static routes file entirely — EGRESS_ROUTES, _reload,
the SIGHUP handler, self.config, and the SUPERVISE_BOTTLE_SLUG env slug. The
per-request /resolve is the only policy source; __init__ fail-closes if
BOT_BOTTLE_ORCHESTRATOR_URL is unset. Introspection (`_egress.local/allowlist`)
now reports the calling bottle's *resolved* routes. The block/redact log gates
and _req_ctx redaction now read the per-flow config/env from the request-time
stash, so they use each bottle's log level and token set (they silently used the
empty static config before). Nothing sends `docker kill --signal HUP` to the
gateway in the consolidated model (the egress applicators fail closed), so
removing the SIGHUP reload is safe.

git_http_backend.py: resolver mandatory; no flat-root fallback. main() refuses
to start without an orchestrator URL; a request whose source resolves to no
bottle 404s.

supervise_server.py: resolver mandatory; every proposal is attributed to the
source-IP-resolved bottle. Remove handle_list_egress_routes (the proxy-fetch
introspection that only worked when the proxy carried one bottle's identity) —
list-egress-routes is answered from the resolved policy. main() refuses to start
without an orchestrator URL.

Tests: a host-side fake resolver serves each test's Config through the real
parse path (a small YAML-subset emitter round-trips route_to_yaml_dict); the
response/websocket hooks stash it as request() would. Deletes the tests for the
removed static-config, SIGHUP-reload, and single-tenant-passthrough paths; adds
fail-closed-without-orchestrator coverage.

Follow-up: gateway_init still forwards SIGHUP to the egress child (now dormant —
no one sends it); the README still describes the docker backend's per-bottle
topology. Both are outside the data-plane teardown.

didericis 2aec30e501 fix(git-gate): install the gitleaks binary for the build's target arch
The gateway Dockerfile hardcoded the linux_x64 gitleaks download, so an
image built on/for aarch64 (Apple Silicon) baked in an x86_64 binary.
It sat quiet until the git-gate pre-receive hook first invoked it, where
the kernel refused the foreign-arch exec — `gitleaks: Exec format error`
— failing every push through that gateway.

Pick the asset + pinned SHA from the build's target architecture:
TARGETARCH (auto-populated by BuildKit) with a `dpkg --print-architecture`
fallback for a legacy builder, and hard-fail on any unsupported arch.
Each arch keeps its own SHA256 verification, so no supply-chain regression.

The existing integration test test_gateway_image.py::
test_gitleaks_binary_present_and_versioned execs `gitleaks version` in the
built image, so it now passes on arm64 instead of hitting the same error.

didericis b1850be5d1 fix(git-gate): make the gateway access-hook executable regardless of copy transport
test / unit (pull_request) Successful in 1m19s
test / integration (pull_request) Successful in 30s
test / coverage (pull_request) Successful in 1m35s
lint / lint (push) Successful in 2m35s

test / integration (push) Successful in 29s
test / coverage (push) Successful in 1m31s
Update Quality Badges / update-badges (push) Successful in 1m21s
Cloning/fetching from the git-gate on the Apple-container backend failed with
"empty reply from server" (curl exit 52). Root cause: the git-http handler
crashed on every upload-pack with

    PermissionError: [Errno 13] Permission denied: '/etc/git-gate/access-hook'

The access-hook is exec'd directly, so it needs the x bit. prepare() stages it
0o700 and trusted the gateway copy to carry that mode. `docker cp` does; the
Apple `container cp` (AppleGatewayTransport) does not, landing the hook 0o644 →
EACCES. The unhandled exception killed the handler thread, closing the socket
with no HTTP response — which the client sees as the opaque empty reply.

- provision_git_gate now `chmod +x`es the access-hook on the gateway side after
  the copy, so it's executable under every transport (docker/apple/firecracker).
- git-http handler wraps the access-hook subprocess.run: an OSError /
  SubprocessError (un-execable, timed out) now fails closed with a 503 instead
  of crashing the thread into an empty reply — a gate that can't run its hook
  should deny, visibly.
- Updates the now-misleading "docker cp preserves source mode" comment in
  git_gate.prepare().

Regression tests: provisioning applies +x to the access-hook; the handler
returns 503 (not an empty reply) when the hook can't be exec'd.

Provision that runner exactly like a normal Firecracker host — `firecracker` on `PATH`, `/dev/kvm`, Docker, the cached guest kernel + static dropbear, and the pool installed as the persistent systemd unit — then register it with the `kvm` label.

## Tracker policy
Issues are the canonical work items and own all tracker labels; every issue
must have at least one. Pull requests stay unlabeled and deliberately reference
an issue with `Closes #…`, `Part of #…`, or another form defined in
[`ADR 0005`](docs/decisions/0005-issues-own-tracker-metadata.md). Gitea Actions
enforces the convention for new work from 2026-07-18 onward. Earlier closed
PRs are grandfathered rather than given artificial retrospective issues.
## Trademarks
bot-bottle is an independent project and is not affiliated with, endorsed by, or sponsored by Anthropic, PBC. "Claude" and "Claude Code" are trademarks of Anthropic, PBC; the project name uses "claude" descriptively to indicate that the tool runs Claude Code inside a sandbox.

# ADR 0005: Keep tracker metadata on issues
- **Status:** Accepted
- **Date:** 2026-07-18
- **Deciders:** didericis
## Context
Gitea exposes labels on both issues and pull requests. Applying the same labels
to both copies planning metadata, creates a synchronization obligation, and
makes disagreements between the two records possible. At the same time,
unlabelled objects look accidental unless the repository states which object
owns the metadata.
The repository already uses issues as work items and PRs as implementations of
those work items. At this decision's cutoff, all open PRs reference issues, but
121 of 219 historically merged PRs do not. Manufacturing retrospective issues
for that history would create records that never participated in planning and
would make the issue history less truthful.
## Decision
Issues are the canonical tracker records and own labels. Every issue has at
least one label. An issue opened or left without labels receives
`Status/Needs Triage` automatically until it is classified.
Pull requests carry no labels. Every new PR deliberately references at least
one existing issue in its title or description with one of these forms:
- `Closes #123`, `Fixes #123`, or `Resolves #123` when merging completes it.
- `Part of #123`, `Related to #123`, `Refs #123`, or `References #123` when it
contributes without completing it.
Gitea Actions enforces both PR rules as a status check and repairs the empty
issue-label state. Branch protection makes the PR policy check required.
The policy applies from 2026-07-18 onward. Existing issues may be labelled as
they are encountered, but closed PRs are grandfathered: no retrospective
issues or PR labels are created solely to make history conform.
## Consequences
- Classification, priority, and workflow metadata have one source of truth.
- A PR's issue link is the navigation path to its planning metadata.
- Multi-PR issues do not require copied or synchronized labels.
- `Status/Needs Triage` is an intentional fallback, not a final
classification.
- Direct issue creation remains convenient; automation repairs a missing label
immediately after creation because Gitea has no native required-label rule.
- The required check must be configured in branch protection after this
workflow lands.

Research conducted 2026-05-11. CubeSandbox added 2026-07-18 (see its
per-project note and the addendum at the end). Also updated 2026-07-18:
bot-bottle no longer uses **pipelock** — outbound DLP is now bot-bottle's
own (deliberately simple) egress scanner (a mitmproxy addon with custom
detectors, PRD 0017 / 0053), and git-push secret scanning is handled by
**gitleaks** in the git-gate. "pipelock" below has been replaced with the
current mechanism; it survives only in older PRDs as history.
Updated again 2026-07-18: six additional tools added (Cleanroom,
container-use, Docker sbx, Anthropic srt, Microsoft AGT, Open Agent
Passport); an **Agent-tailored policy** row added to the comparison table;
a separate Governance layers section added for AGT and OAP. See the
second addendum at the end.
## Summary
Eight projects surveyed. None duplicate bot-bottle's combination of
local Docker, declarative JSON manifest, per-agent egress allowlist via
pipelock, and bottle/agent split. Two clusters stand out:
Fifteen projects surveyed across two categories: isolation/sandbox tools
and governance/pre-action authorization layers (the latter don't provide
VM or container isolation but do per-agent policy enforcement at the
tool-call level). None duplicate bot-bottle's combination of local
VM-per-bottle isolation, a declarative per-role manifest, per-agent
egress allowlist + outbound-content DLP, bottle/agent split, and the
composable `extends:` policy model. Three clusters stand out:
- **Closest neighbours** — agent-safehouse and litterbox: local,
single-user, thin wrappers over an existing OS primitive
(`sandbox-exec`, Podman + Landlock).
- **Different category** — tilde.run (hosted SaaS), boxlite and
microsandbox (microVM libraries for platform builders), endo-familiar
- **Different category (isolation)** — tilde.run (hosted SaaS), boxlite
and microsandbox (microVM libraries for platform builders), CubeSandbox
(self-hosted multi-tenant microVM service), endo-familiar
(capability-security paradigm, no OS isolation).
- **New: governance/pre-action layers** — Microsoft AGT and Open Agent
Passport (OAP): framework-embedded tool-call interceptors with
per-agent declarative policy. Closest competitors on agent-tailored
policy, but operate at the tool-call level rather than providing
network/filesystem isolation; they complement rather than substitute.
The microVM cluster (matchlock, smolmachines, boxlite, microsandbox) is
the most relevant for the v2 isolation discussion in
The microVM cluster (matchlock, smolmachines, boxlite, microsandbox,
CubeSandbox) is the most relevant for the v2 isolation discussion in
[`stronger-isolation-alternatives.md`](stronger-isolation-alternatives.md):
libkrun and Apple's Virtualization.framework have made local microVMs
ergonomic enough that a `"runtime": "microvm"` option on a bottle is now
plausible without a heavy stack.
ergonomic enough that microVMs are **now bot-bottle's default backend**
(Firecracker on KVM Linux, Apple Container on macOS), with Docker kept
only as a legacy fallback for CI / hosts without KVM or Apple Container.
That discussion has since shipped, not just been theorized.
**The one that matters most for positioning is CubeSandbox** — it is the
first surveyed project to ship bot-bottle's would-be wedge (default-deny
egress allowlist + full audit logs + in-flight credential custody so keys
never enter the sandbox) *combined with* per-sandbox microVM isolation,
open-source under Apache 2.0, with Tencent Cloud behind it and 10.4k
stars. It's a self-hosted multi-tenant service for platform builders, not
a single-user declarative tool, so it doesn't collide head-on — but it
narrows the "nobody else bundles egress custody + credential injection"
claim that the monetization positioning leans on. See the addendum.

- **Agent integration**: **Drop-in E2B SDK replacement** (single env-var
change) — the headline compatibility claim. OpenClaw assistant
integration; general LLM-code execution. Aimed at platform builders,
not one developer's laptop.
- **Config**: Programmatic via the E2B-compatible SDK. No declarative
manifest.
- **Network policy**: This is the striking part — **domain allowlists,
instant block on unauthorized egress, full audit logs, per-sandbox
traffic tokens, policy-routing egress**, enforced by an eBPF-based
virtual switch giving kernel-level network isolation. Closest match yet
to bot-bottle's own default-deny + per-bottle allowlist egress model.
- **Credentials**: **Credential vault** — agents call external APIs / LLMs
while "keys never enter the sandbox, model context, or logs." Same
in-flight-injection idea as matchlock, but productized as a vault.
- **Performance**: <60ms cold start (claimed 2.550× faster than
alternatives), <5MB memory per instance; millisecond snapshot rollback
is upcoming.
- **Maturity**: Open-sourced July 2026 off production Tencent Cloud use;
most-starred project in this set (~10.4k).
### Cleanroom *(added 2026-07-18)*
- **Source**: https://github.com/buildkite/cleanroom
- **License**: Apache 2.0
- **Isolation**: MicroVM — Firecracker on Linux, Virtualization.framework
on macOS. Digest-pinned OCI images.
- **Locality**: Self-hosted server (CI-oriented).
- **Agent integration**: Generic process sandbox; CI-first, not a
Claude/agent wrapper.
- **Config**: `cleanroom.yaml` in the repo being sandboxed defines egress
rules, resources, and network policy. Cleanroom resolves this from the
commit being run.
- **Network policy**: Default-deny + per-repo hostname allowlist (resolved
from DNS answers + destination IP:port). Co-hosted services on the same
IP:port are not distinguished. OIDC-backed auth for remote servers.
- **Credentials**: Host-side only; not injected in-flight but not present
in the VM.
- **Notable**: Policy lives in the *repo being sandboxed*, not in an
agent-role definition — closer to per-repo scoping than per-role.
Supports Docker-inside-sandbox (`services.docker.required: true`), OIDC
authorization, suspend/resume lifecycle.
- **Maturity**: Active Buildkite product.
### container-use *(added 2026-07-18)*
- **Source**: https://github.com/dagger/container-use
- **License**: Apache 2.0
- **Isolation**: Docker container per agent + git worktree per agent.
Containers share the host kernel; stronger than bare host but weaker
than microVM.
- **Locality**: Local.
- **Agent integration**: MCP stdio server — Claude Code, Cursor, Windsurf.
`claude mcp add container-use -- container-use stdio`.
- **Config**: None for security policy. Environments are provisioned on
demand; no allowlist or credential config.
- **Network policy**: Not addressed.
- **Notable**: Per-agent git branches (`container-use/<env_name>`);
parallel agents without filesystem conflict; real-time log visibility
and terminal attach for intervention; git-based review workflow.
Oriented toward parallel development safety, not security containment.
- **Maturity**: Early development, active.
### Docker sbx *(added 2026-07-18)*
- **Source**: Docker proprietary (`sbx` CLI, separate from `docker`).
- **License**: Proprietary.
- **Isolation**: MicroVM (Docker's own implementation) — each session gets
its own kernel, Docker daemon inside the VM, and filesystem.
- **Locality**: Local (macOS and Windows; does not require Docker Desktop).
- **Agent integration**: Explicit wrapper — Claude Code, Codex, Gemini
CLI, Copilot CLI, Kiro. Launches agent inside the VM with
`--dangerously-skip-permissions` by default.
- **Config**: Open / Balanced / Locked Down network presets at launch. No
per-role manifest.
- **Network policy**: Default-deny; preset levels control strictness. TUI
dashboard shows a live log of every outbound connection (allowed and
blocked) with point-and-click allow/block for hosts.
- **Credentials**: OS keychain + host-side proxy injection — API keys
never enter the VM.
- **Notable**: Best DX among microVM tools (one command, works like native
yolo Claude but inside a VM); branch mode creates a git worktree in
`.sbx/`. Network policy is preset-based, not role-declarative.
- **Maturity**: GA 2026.
### Anthropic srt *(added 2026-07-18)*
- **Source**: https://github.com/anthropic-experimental/sandbox-runtime
(`@anthropic-ai/sandbox-runtime` on npm, `sandbox-runtime` on PyPI)
- **License**: Apache 2.0 (experimental).
- **Isolation**: OS-level only — Seatbelt (`sandbox-exec`) on macOS,
bubblewrap on Linux, WFP (Windows Filtering Platform) account-fenced on
Windows. **No container or VM.** Lowest overhead in the set.
- **Locality**: Local.
- **Agent integration**: Claude Code's sandboxed bash tool uses this
internally. Can wrap any arbitrary process (`srt <command>`). Cloud
Claude Code sessions use full microVMs instead.
- **Config**: Programmatic per-invocation — allow/deny path lists for
filesystem; allow/denylist for network (HTTP proxy + SOCKS5).
- **Network policy**: Proxy-based filtering (HTTP + SOCKS5); domain
allowlist/denylist enforced at proxy layer. Custom proxy supported
(e.g. mitmproxy for inspection + audit). Processes that ignore proxy
env vars may bypass filtering on some platforms.
- **Notable**: Cross-platform (macOS/Linux/Windows); wraps any process,
not just agents; no role/manifest concept. Annotated as a research
preview — APIs may change.
- **Maturity**: Early research preview.
## Governance / pre-action authorization layers
These two tools don't provide VM or filesystem isolation; they intercept
tool calls before execution and evaluate them against a per-agent
declarative policy. They are the closest competitors on **agent-tailored
policy** and complement isolation sandboxes rather than substituting for
them.
### Microsoft Agent Governance Toolkit (AGT) *(added 2026-07-18)*
- **Source**: https://github.com/microsoft/agent-governance-toolkit
- **License**: MIT (~3.3k stars, open-sourced April 2, 2026).
- **Isolation**: None (OS/VM). Execution rings (03, inspired by CPU
privilege levels) control what an agent can do at the framework layer.
MCP security gateway treats MCP traffic as an untrusted boundary.
- **Locality**: Embedded in the agent framework (Python, TypeScript, .NET,
Rust, Go; 20+ framework adapters).
- **Agent integration**: Framework-agnostic. Plugs into Semantic Kernel,
AutoGen, and others as a middleware layer.
- **Config**: YAML policy per agent — tools can be `allowed`, `denied`,
`sandboxed`, or routed through an `approval` step. Every action passes
through a governance gate checking: agent DID, trust score, risk tier,
requested tool, action type, and policy rules.
- **Network policy**: Not directly — operates at tool-call level.
- **Credentials**: Per-agent DID (Ed25519 decentralized identifier); agent
does not borrow a human's credentials.
- **Notable**: Dynamic trust score (01,000, behavioral decay) —
privilege follows observed behaviour, not just provisioning. Covers all
10 OWASP Agentic Top 10 risks. Kill switch + SLO monitoring. Sub-ms
policy enforcement.
- **Maturity**: MIT, ~3.3k ⭐, v3.7.0 May 2026.
### Open Agent Passport (OAP) *(added 2026-07-18)*
- **Source**: https://github.com/aporthq/aport-spec ; spec at
https://api.aport.io/spec/spec/oap/oap-spec.md/ ; arXiv 2603.20953
- **License**: Open specification.
- **Isolation**: None. Pre-action hook only — intercepts tool calls
synchronously before execution, evaluates against a cloud-registry
declarative policy, fails closed.
- **Locality**: Local hook + cloud policy registry.
- **Agent integration**: Framework-agnostic; hook pattern.
- **Config**: Declarative policy rules in a cloud registry (evaluated in
order; first failing rule denies). Ed25519-signed, hash-chained audit
records per decision.
- **Network policy**: Not directly.
- **Notable**: 53ms median authorization decision (N=1,000). In an
adversarial testbed ($5,000 bounty, 1,151 sessions), social engineering
succeeded 74.6% of the time under a permissive policy; under a
restrictive OAP policy, 0% success across 879 attempts. Assumes
framework runtime is not compromised.
- **Maturity**: Specification + reference implementation, 2026.

## What's closest, what's different
**Closest in design and scope.** agent-safehouse and litterbox sit
nearest bot-bottle: local, single-user, thin wrappers over an
existing OS primitive, low-dep. The split is the isolation primitive —
bot-bottle uses Docker + pipelock egress (plus gVisor where
available); agent-safehouse uses `sandbox-exec`; litterbox uses Podman +
Landlock. matchlock and smolmachines are spiritually close on the
*policy* side (default-deny net, per-host allowlist) but use microVMs
instead of containers.
bot-bottle now defaults to a VM per bottle (Firecracker microVM on KVM
Linux, Apple Container on macOS) with its own DLP-scanning egress proxy,
keeping Docker only as a legacy fallback; agent-safehouse uses
`sandbox-exec`; litterbox uses Podman + Landlock. matchlock and
smolmachines are close on *both* the policy side (default-deny net,
per-host allowlist) and — now that bot-bottle has moved off
containers-by-default — the microVM isolation primitive.
**New closest on agent-tailored policy.** Two governance tools are the
direct competitors on the "coarse-grained sandbox" axis. **tilde.run**
has had per-agent DSL RBAC since its launch (though it's hosted SaaS).
**Microsoft AGT** is the most serious new entrant: per-agent DID
identity, YAML policy that can allow/deny/sandbox/approve individual tool
calls per agent, and a dynamic behavioural trust score. It operates at
the framework tool-call layer, not the network layer — so it's
complementary to bot-bottle's network/filesystem isolation rather than a
direct substitute, but on the "does this sandbox know what this agent is
for?" question it is the most complete answer in the field. OAP's
pre-action hook pattern achieves similar goals with cryptographic audit
and a 0% adversarial-attack success rate under a restrictive policy.
**New closest on DX.** **Docker sbx** is the first tool in this set that
matches bot-bottle on the "one command, dangerously-skip-permissions safe
by default" DX bar, at microVM isolation strength, with host-side
credential injection. It is proprietary, preset-based (not role-
declarative), and cloud-agent-specific, but it directly competes on the
UX proposition. agent-safehouse was the previous DX peer; Docker sbx
materially raises the bar.
**New closest on repo-scoped policy.** **Cleanroom** (Buildkite) is the
first tool to combine microVM isolation with a declarative egress policy
file — though the policy lives in the repo being sandboxed
(`cleanroom.yaml`), not in an agent-role manifest. That makes it per-
repo rather than per-role: the same Cleanroom config applies to any
agent running in that repo. The distinction matters for bot-bottle's
use case (one developer running multiple agent *roles* with different
egress footprints), but for CI/CD use cases Cleanroom is a direct
alternative.
**Solving a different problem.** tilde.run is hosted SaaS for team /
production agent pipelines with data-versioned rollback — explicitly
opposite to bot-bottle's "infrastructure I control" goal. boxlite and
microsandbox are infrastructure libraries aimed at platform builders
embedding sandboxes into agent frameworks; they would be a *backend*
bot-bottle could call, not a competitor to its manifest layer.
endo-familiar is in a different paradigm entirely: capability passing
rather than kernel boundaries.

## Borrowable ideas
What bot-bottle already has that the survey suggested as
differentiators:
- Default-deny egress with a per-agent allowlist (pipelock).
- Default-deny egress with a per-agent allowlist (own egress scanner).
- DLP scanning of outbound traffic.
- Bottle / agent split (manifest layer above the isolation primitive).
- gVisor auto-detection on Linux.

stance:

3. **MicroVM backend as an opt-in bottle type** — already on the radar
in `stronger-isolation-alternatives.md`. microsandbox, smolmachines,
and matchlock all show that libkrun + Apple's
Virtualization.framework is ergonomic enough that a
`"runtime": "microvm"` field on a bottle is plausible without a heavy
stack.

and matchlock demonstrated turned out to be enough to make it the
default rather than an opt-in.

not independently verified here.
## Addendum 2026-07-18 — CubeSandbox and the positioning read
CubeSandbox (Tencent Cloud, Apache 2.0, ~10.4k stars, HN launch
[#47863430](https://news.ycombinator.com/item?id=47863430)) is the first
project in this survey to combine, in one open-source stack, everything
bot-bottle treated as its differentiator:
- **Egress custody (connection level)** — default-deny domain allowlist
(L7 domain/SNI filtering), instant block on unauthorized egress,
per-sandbox traffic tokens, full audit logs of destinations (eBPF
virtual switch, "CubeVS"). This matches bot-bottle's egress scanner at
the *connection level*, productized — see the one thing it does **not**
match, below.
- **Credential custody** — a vault where keys "never enter the sandbox,
model context, or logs." This is the in-flight-injection idea from
matchlock, but as a first-class feature, and it's exactly the
cross-vendor "egress audit + custody" wedge the monetization
positioning treats as the one defensible moat.
- **Isolation on par with bot-bottle's current default** — a dedicated
guest kernel per sandbox (RustVMM/KVM). bot-bottle now defaults to the
same class of boundary (Firecracker microVM / Apple Container), so this
is parity, not an edge; CubeSandbox's remaining edge is running that
per-kernel isolation multi-tenant at scale on one host.
The one axis CubeSandbox does **not** cover — and where bot-bottle stays
distinctive:
- **Content DLP on *authorized* channels.** CubeSandbox's egress control
is connection-level: it decides *whether* a destination is allowed and
logs it, and its vault keeps *injected* credentials out of the sandbox
entirely. Neither inspects the *payload* of traffic to an allowed
destination. So an agent that exfiltrates over a permitted channel —
pasting a repo's contents, an agent-derived secret, or PHI into an
allowed API/domain — is not caught by CubeSandbox. bot-bottle's own
egress DLP scanner does scan that: response + websocket content against
the resolved per-flow config, with per-bottle token redaction (see
recent egress commits). The vault
approach is arguably *stronger* for the specific case of pre-known
injected credentials (they can't leak if they were never present), but
it is not a substitute for content inspection of everything else.
**Long-running posture — a sharper axis than raw isolation.** E2B and
CubeSandbox are *ephemeral-per-task* by design; a long-running agent is an
architected pattern on top, not the default. E2B: 5-minute default
timeout, continuous runtime tier-capped (~1h Hobby / ~24h Pro), duration
achieved via **pause/resume** (preserves filesystem + memory + processes;
reconnect by sandbox ID via `Sandbox.connect()`; resume resets the timeout
to 5 min; auto-pause via `on_timeout: "pause"`). CubeSandbox mirrors this
(E2B drop-in) with first-class auto pause/resume and hundred-ms
checkpoint/fork — and, self-hosted, sets its own timeout policy with no
vendor tier caps. bot-bottle inverts the model: a bottle is **persistent,
named, and supervised by default** — long-running *is* the default, not a
session-management loop over pause/resume. smolmachines is the other
persistent-by-default project in this set. For anyone building agents that
run for hours/days, this posture difference matters more than the
isolation primitive.
**DX — the "run Claude yolo-style" bar.** The reason `claude
--dangerously-skip-permissions` is so widely used is DX: it's one command
and the agent just goes. The bottle thesis is to make a *sandboxed* run
that easy — `start <agent>` builds the image on first run and drops you
into an interactive Claude session that already has
`--dangerously-skip-permissions` on by default
(`contrib/claude/agent_provider.py`), with the sandbox as the guardrail
instead of per-action prompts. On this axis the field splits cleanly:
- **Wrappers around the agent** (as-easy-as-native): bot-bottle and
**agent-safehouse** (`safehouse claude --dangerously-skip-permissions`).
These *are* the run-Claude experience. agent-safehouse is the real DX
peer — but it's macOS-only Seatbelt, single-run, and doesn't address
network egress; bot-bottle adds VM-grade isolation, egress DLP, and
persistent/parallel bottles across macOS + Linux.
- **Libraries / services** (you build the run yourself): boxlite,
microsandbox, CubeSandbox, E2B. These hand you an SDK or a cluster and
expect you to wire the agent in — powerful for platform builders,
heavyweight for "just run Claude on my laptop." microsandbox's MCP/Skills
angle is *sandbox-as-a-tool the agent calls*, which is the inverse of
wrapping the agent.
- **In between:** litterbox (wizard + build, Linux only), smolmachines
(SSH into a named machine), matchlock (run a command in a VM).
So DX is a genuine bot-bottle differentiator, and the only project that
matches it (agent-safehouse) does so with materially weaker isolation and
no egress story. "As easy as native yolo, but actually sandboxed" is a
defensible one-liner.
Why it still doesn't collide head-on:
1. **Shape.** CubeSandbox is a *multi-tenant service for platform
builders* (drop-in E2B replacement, SDK-driven, 2,000 sandboxes on a
box). bot-bottle is a *single-operator, declarative-manifest tool for
the infrastructure I run*. Different buyer, different ergonomics — no
JSON manifest, no bottle/agent split, no "one command on my laptop."
2. **Backend, not competitor.** Like boxlite/microsandbox, CubeSandbox is
something bot-bottle could sit *on top of* — a `"runtime": "microvm"`
or `"runtime": "cubesandbox"` backend under the manifest layer — while
keeping the manifest, the bottle/agent split, and the local,
single-operator default.
Why it matters anyway:
- The "nobody else bundles connection-level egress allowlist + audit +
in-flight credential custody" line is **no longer true for the
primitive** — a well-funded, 10k-star open-source project now ships it.
But **content DLP on authorized channels is still not matched** (see
above), and neither is the *layer above* the primitive (declarative
manifest, cross-vendor orchestration, operator UX, the
phone-control/dashboard north star). Those two — outbound-payload DLP
and the orchestration layer — are where the defensible ground now sits;
the connection-level allowlist + vault mechanism, on its own, is no
longer differentiating. Revisit the monetization open/paid line with
that in mind.
- Worth a closer look at **how** CubeSandbox does credential injection
and per-sandbox egress tokens (eBPF virtual switch vs. bot-bottle's
mitmproxy egress proxy) before the next iteration of bot-bottle's
in-flight-secret feature — see borrowable idea #2 above.
## Addendum 2026-07-18 (second pass) — agent-tailored policy landscape
The second-pass question was: how novel is bot-bottle's per-agent,
role-tailored sandbox relative to the expanded field?
**The short answer:** on the isolation + network + role-tailoring
combination, bot-bottle remains the only tool in this set. On
role-tailored *policy at the tool-call level*, Microsoft AGT and OAP are
the most complete answers, but they don't provide isolation; they
complement rather than substitute.
**The competitive picture by axis:**
- *Agent-tailored egress (declarative, per-role)* — bot-bottle and
tilde.run. Cleanroom is per-repo, not per-role. Everyone else is
per-session or not addressed.
- *Agent-tailored tool-call policy (declarative, per-agent identity)*
Microsoft AGT (YAML policy + DID identity + trust score), OAP
(declarative policy rules + cryptographic audit). Neither provides
network/filesystem isolation.
- *Composable policy (role overlays)* — bot-bottle (`extends:`). No
other tool surveyed supports composable role-policy inheritance.
- *Isolation + DX (one-command safe yolo)* — bot-bottle and Docker sbx.
Docker sbx is proprietary, preset-based, and cloud-agent-specific;
it's the first DX-class competitor at microVM isolation strength.
**What the HN "coarse-grained" complaint maps to:** The complaint is
that a VM isolates the filesystem but doesn't know if the agent
*should* be sending an email. bot-bottle's bottle/agent split is a
structural answer to this: the bottle manifest declares exactly what
the role can reach, and the sandbox enforces it at the network layer.
Microsoft AGT is the most complete answer at the semantic/tool-call
layer. The gap both leave open is *intent classification* — knowing
whether a permitted action is consistent with the agent's actual task.
See `hn-agent-safety-discourse-july-2026.md` for the blast-radius
analysis.
**Borrowable from new tools:**
- **Microsoft AGT's trust-score decay** — privilege that reflects
observed behaviour rather than static provisioning. Applied to
bot-bottle: a bottle that has triggered DLP alerts or supervise holds
could auto-downgrade its network preset, or flag the session for
closer review. Fits the existing supervise-server architecture.
- **Docker sbx's live network TUI** — real-time per-session view of
allowed and blocked outbound connections with point-and-click
allow/block. `cli.py supervise` is the right surface; adding a
live-connections panel would directly address the "I can't see what
the agent is doing" gap without any backend changes.
- **OAP's cryptographic audit chain** — Ed25519-signed, hash-chained
audit records. Currently bot-bottle logs egress decisions but doesn't
chain them. A tamper-evident audit record per session would be useful
for the compliance use case the CubeSandbox positioning targets.

# HN discourse on agent sandbox safety — June/July 2026
A survey of community opinion and notable security disclosures on Hacker
News and adjacent sources over JuneJuly 2026. The question: what does
the current discourse say about whether sandboxes are sufficient for
agentic AI safety, and where does bot-bottle land against the issues
being raised?
Research conducted 2026-07-18.
## Summary
The past month marks a turning point in community opinion. Earlier in
2026, the debate was mostly "which sandbox tool is best?" By JuneJuly,
a cascade of critical CVEs and novel attack classes has shifted the
framing to "sandboxes are not enough — what else do you need?" The
attacks that drove this shift are structurally distinct: most route
through legitimate, trusted channels (Sentry issues, MCP descriptions,
README files) rather than exploiting the isolation boundary directly.
bot-bottle's architecture holds up well against the direct-escape class
(Firecracker/Apple Container default backends, credentials never in the
agent's env, harness entirely on the host). The remaining gap is prompt
injection — attacker-controlled data interpreted as model instructions.
Egress controls and prompt injection defenses are orthogonal: egress
limits what the agent can *send out*; injection is about what it is
*told to do*. The two don't substitute for each other. Inside a tightly-
egressed sandbox a successful injection can't exfiltrate to unknown
hosts, but it can still corrupt the work product, push malicious commits
past a secret scanner, or use allowlisted channels for exfiltration.
Those residual risks are addressed below.
## The sandboxing boom sets the stage
The preceding months generated a wave of sandbox tooling. A March 28
Ask HN thread
([#47444917](https://news.ycombinator.com/item?id=47444917)) catalogued
the explosion: E2B, AIO Sandbox, AgentSphere, Yolobox, Exe.dev,
AgentFence, DenoSandbox, Capsule (WASM), ERA, Vibekit, Daytona, Modal,
Nono, and more — all launched within roughly 12 months. A parallel March
9 thread ([#47185250](https://news.ycombinator.com/item?id=47185250))
surveyed what developers were actually deploying: "containers or YOLO"
dominated. The honest community mood was that most teams hadn't solved
this and were shipping anyway.
## The JuneJuly attack cascade
Six attack patterns broke in quick succession. Together they form the
argument that the community's framing was wrong: the threat model for
agents isn't just "code that escapes its container" — it's also prompt
injection, where attacker-controlled data is interpreted as model
instructions regardless of whether any isolation boundary was crossed.
Sections 24 below are all the same attack class; the "trusted channel"
label describes the delivery vector, not a different threat.
### 1. Sandbox escape CVEs (DuneSlide, CVE-2026-39861)
Cato AI Labs disclosed **DuneSlide** (CVE-2026-50548/50549, CVSS 9.8),
a pair of flaws in Cursor 2.x. CVE-2026-50548 abuses the sandbox's
`working_directory` parameter to point writes at system files; CVE-26-50549
exploits a symlink-resolution fallback that fails open. Both start with
a prompt injection and end in sandbox escape — and Cato's framing was
blunt: "each CVE defeats a different guardrail; the problem is
structural, not a string of one-offs."
Claude Code's own sandbox had a similar escape this year:
**CVE-2026-39861** (symlink flaw). The CurXecute/MCPoison/CVE-2026-26268
chain from Cursor added a poisoned Slack message, a swap-after-approval
MCP config, and a Git hook as three more entry points in the same
attack class.
All patched, but the pattern holds: any application-level sandbox that
takes attacker-influenced values as path parameters is reachable from a
prompt injection.
### 2. Prompt injection via MCP data (Agentjacking)
Tenet's "Agentjacking" technique planted a fake bug report in Sentry's
MCP output. When an agent queries Sentry to fix open issues, the
malicious event is rendered as structured content visually
indistinguishable from a real Sentry event, and the agent executes the
embedded instructions with the developer's full privileges. Hit rate
across Claude Code and Cursor: **85%**. The route is entirely through a
legitimately-authorized MCP channel — no isolation boundary is crossed;
the injection arrives inbound through a channel the sandbox explicitly
trusts.
The Cloud Security Alliance's summary: treat observability, bug-report,
and integration data as **untrusted agent input**, not neutral
development metadata.
### 3. README-embedded prompt injection
A July disclosure showed malicious instructions hidden in `README.md`
— a file that receives no trust prompt and requires no elevated access.
When asked point-blank whether the repo held hidden instructions, both
Claude Sonnet 4.6 and GPT-5.5 said no. A payload written for Sonnet
4.6 transferred unchanged to Sonnet 5, Opus 4.8, and GPT-5.5. The
attack surface is every repo an agent is asked to work in.
### 4. Prompt injection via MCP tool descriptions
Microsoft research (June 30) showed that attacker-controlled MCP tool
description fields can silently redirect agent behavior. The injection
is embedded in metadata the model reads during tool selection — before
any sandbox enforcement or egress check runs, and entirely on the
inbound path that egress controls cannot touch.
### 5. MCP STDIO command injection (10 CVEs)
OX Security disclosed a systemic command injection class in Anthropic's
MCP protocol, covering 10 CVEs across multiple coding agents. The
Windsurf case (CVE-2026-30615): processing attacker-controlled HTML
causes the agent to auto-register a malicious MCP STDIO server and
execute arbitrary commands with no further user interaction.
### 6. LiteLLM gateway compromise (CVE-2026-40217, CVE-2026-42271)
CVE-2026-40217 exposes LiteLLM's guardrail sandbox via `exec()` with no
source filtering. CVE-2026-42271 (exploited in the wild, added to CISA's
KEV catalog) lets callers spawn subprocesses through MCP preview
endpoints. The threat extends to any agent routed through a compromised
LiteLLM proxy: the proxy can swap model responses for forged tool calls
in transit, giving the attacker a reverse shell from the developer's
machine.
## HN community opinion clusters
**"Move enforcement to the kernel, not the app"** — the Nono Show HN
([#46849615](https://news.ycombinator.com/item?id=46849615)) and a
kernel-sandbox thread
([#47066574](https://news.ycombinator.com/item?id=47066574)) both argued
that application-layer sandboxes are inherently bypassable by the code
they're sandboxing. The academic framing, from *Red-Teaming the Agentic
Red-Team* ([arXiv 2606.24496](https://arxiv.org/pdf/2606.24496)):
"enforcement should occur at the OS level via the kernel refusing system
calls that violate policy at runtime — not pre-execution argument
validation in tool calls."
**"The harness belongs outside the sandbox"** — a May thread
([#47990675](https://news.ycombinator.com/item?id=47990675)) converged
on clean architectural separation: harness in one VM, tool execution in
another. Top comment: "having the harness in one VM, and tool use applied
to user data in another, is about as safe as you can be at present."
Several replies described a hypervisor-like policy layer — sitting outside
both VMs — as the right long-term model.
**"Sandboxes are too coarse-grained"** — a Feb thread
([#47006445](https://news.ycombinator.com/item?id=47006445)) argued
that VMs don't answer the real question: knowing whether an agent
*should* be sending an email or making a transaction. "Everything's just
in the same big box." This framing picked up traction through JuneJuly
as the trusted-channel attacks dominated.
**"MCP's trust model is the real problem"** — the month's recurring
theme. MCP by design gives agents access to authorized external services.
Once a trusted channel delivers a malicious payload, filesystem sandboxing
is irrelevant. The community call: treat all MCP tool metadata and return
values as untrusted input subject to policy validation before ingestion,
and disable automatic MCP server loading from untrusted repositories.
## How bot-bottle addresses these issues
### What it covers well
**Direct sandbox escape (CVEs, container breakout)**
bot-bottle's default backends are Firecracker microVM (KVM Linux) and
Apple Container (macOS). Both run the agent in a separate VM with a
dedicated kernel — the container-escape CVE class (Dirty Pipe, runc
escapes, DuneSlide's path-parameter abuse) requires escaping a real
hypervisor boundary, not just a namespace. On the legacy Docker backend,
gVisor auto-detection provides a userspace syscall barrier for hosts where
neither KVM nor Apple Container is available.
The bot-bottle process itself runs entirely on the host, outside the VM.
This is the "harness outside the sandbox" architecture the HN thread
converged on as best practice. The bottle manifest, egress rules, and
secrets never enter the agent VM.
**Credential theft on sandbox escape**
Even on a successful VM/container escape, the agent has nothing useful
to steal. Credentials are injected in-flight by the gateway proxy
(`auth.scheme` / `auth.token_ref` in the egress route config) — `printenv`
inside the agent shows proxy URLs only. The git-gate similarly holds the
upstream SSH credential on the host; the agent pushes through a
gitleaks-scanned daemon that forwards clean refs upstream. An escaped
agent gets the host filesystem, not the keys.
**Orphaned-agent credential risk**
bot-bottle is explicitly ephemeral: when the agent exits, `cli.py` tears
down every gateway and both networks — nothing persists between runs. The
agent never holds credentials, so there is nothing to orphan.
**MCP config redirection / STDIO auto-registration**
The trust boundary at `$HOME` means bottles live only under
`~/.bot-bottle/bottles/` — a cloned repo cannot add egress routes or
redirect env vars to attacker hosts (the design rationale is in
`docs/prds/0011-per-file-md-manifest.md`). Auto-registering a malicious
MCP STDIO server from within the agent is still sandboxed by the VM, and
any outbound calls from that server must pass the egress allowlist and
outbound DLP scanner.
**Per-agent role tailoring (the "coarse-grained sandbox" complaint)**
The Feb 2026 HN thread that argued "sandboxes are too coarse-grained"
was pointing at a real gap: a VM isolates the filesystem but doesn't
know whether an agent *should* be sending email or calling an external
API. bot-bottle's bottle/agent split is a structural answer at the
network layer — the bottle manifest declares exactly what each role can
reach (which hosts, which paths, which HTTP methods), and the egress
scanner enforces it. A `gitea-dev` bottle that only lists
`gitea.dideric.is` and `api.anthropic.com` structurally cannot send
email or reach AWS, not because the model was told not to, but because
those routes don't exist.
The `extends:` composition model means provider-level policy (the Claude
auth route) lives in one base bottle and role-specific overlays are
stacked on top — no duplication, and changing the base propagates to all
derived roles.
Competitive position on this axis (from `agent-sandbox-landscape.md`):
| Tool | Agent-tailored policy |
|---|---|
| **bot-bottle** | Yes — declarative per-role manifest; `extends:` composition; egress + credentials scoped to role |
| **tilde.run** | Yes — per-agent DSL RBAC (allow/deny/approve per action/repo/agent), but hosted SaaS |
| **Microsoft AGT** | Yes — YAML policy + per-agent DID + trust score, but tool-call level only (no network isolation) |
| **OAP** | Yes — declarative pre-action policy + cryptographic audit, but no isolation |
| **Cleanroom** | Partial — per-repo `cleanroom.yaml`, not per-role |
| **Docker sbx** | No — network presets only |
| **Anthropic srt** | No — programmatic per-invocation |
| **matchlock / smolmachines / microsandbox** | No |
| **agent-safehouse** | Partial — per-agent Seatbelt profiles; no egress |
Two takeaways: bot-bottle and tilde.run are the only isolation tools
with declarative role-tailored policy; Microsoft AGT and OAP are the
closest competitors on role-tailoring but operate at the tool-call layer
without network/filesystem isolation — complementary, not substitutes.
**Outbound exfiltration (any injection class)**
Whatever triggers the agent — README injection, Agentjacking, MCP
description poisoning — the final step in most attacks is exfiltration.
bot-bottle's egress allowlist is default-deny with a per-bottle host
allowlist; unknown hosts get a hard 403. Outbound DLP scanning
(`outbound_detectors: [token_patterns, known_secrets]`) catches tokens
and secrets in outbound bodies; the `supervise` policy (default for
manifest routes) holds the request for operator approval rather than
silently blocking it. Together these limit what a successful injection
can *do* even if it succeeds at the model layer.
**LiteLLM / compromised-proxy attacks**
bot-bottle does not use LiteLLM. The model API route (e.g.
`api.anthropic.com`) is an auto-injected provider route on the egress
allowlist; the agent dials the gateway, not the model API directly.
A compromised third-party proxy is not in the architecture.
### Where it is weaker
**Prompt injection**
Egress controls and prompt injection defenses are orthogonal. Egress
limits what the agent can *send out* (outbound leg); prompt injection
is about what attacker-controlled data *tells the agent to do* (inbound
leg). The two don't substitute for each other and must be treated
separately.
The inbound DLP scanner (`inbound_detectors: [naive_injection_detection]`)
is the only runtime defense against injection arriving through allowlisted
channels — Sentry MCP responses, MCP tool descriptions, README content.
It is explicitly pattern-matching and will not catch a sufficiently
crafted payload. There is no semantic / intent-level gate between what
the model decides and what the agent executes.
**Blast radius within the permitted scope**
Inside a tightly-egressed sandbox a successful injection can't
exfiltrate to unknown hosts, but it still has real options:
- *Work product corruption.* The agent can modify, delete, or backdoor
files in the working directory. This is within its permitted scope;
egress controls have nothing to say about it.
- *Malicious commits past the git-gate.* The git-gate scans outbound
refs for secrets (gitleaks), not for semantic code intent. A prompt-
injected agent can commit subtly malicious code — logic bombs,
backdoored auth paths, code that exfiltrates data through the
application's own HTTP clients at runtime — that looks clean to a
secret scanner.
- *Exfiltration through allowlisted channels.* If an attacker knows or
can predict what hosts are in the egress allowlist, those channels are
available for exfiltration. A GitHub remote being allowlisted means
"push to an attacker-controlled fork" is viable. A logging endpoint
being allowlisted means structured data can leave through it. The
outbound DLP scanner catches credential tokens and known secrets but
not arbitrary business data.
- *Dependency installation within the sandbox.* An agent that runs
`npm install` or `pip install` on attacker-specified packages executes
code inside the sandbox with the same capabilities the agent has:
filesystem access, tool calls, calls to allowlisted hosts. Supply chain
injection via package names is in the same injection family, triggered
by the same prompt-injection path.
### What would close the remaining gaps
The blast-radius risks above point at two distinct mitigations that
don't yet exist in bot-bottle:
- *Outbound intent classification.* The egress addon today scans
outbound request content for token patterns. What it lacks is
awareness of context — it can't distinguish "agent is pushing a
legitimate commit" from "agent was injected and is pushing a backdoor."
The `supervise` policy is already the right shape for human-in-the-loop
review on sensitive outbound actions; extending it with context from
the agent's recent tool calls (what files were touched, what was the
triggering task) would narrow the gap.
- *Semantic code review on git push.* gitleaks is the wrong tool for
catching injected logic. A review step on outbound commits — even a
simple diff summary surfaced in `cli.py supervise` before the push is
forwarded — would close the malicious-commit path without requiring
the agent to be fully trusted.

# Scanning for malicious commits at the git-gate — and whether the semantic layer is a paid feature
A sandboxed agent's most durable way out isn't live exfiltration — it's the
**artifact it pushes**. Code committed through the git-gate leaves the
sandbox and runs *later*, in CI or production, with none of the bottle's
isolation or egress control. gitleaks covers *secrets* on that channel
(see [`git-gate` pre-receive](../../bot_bottle/git_gate_render.py)); this
note asks the harder question — can we scan for *malicious code* in
commits — and the product question the answer raises: is the semantic
(LLM) layer a decent paid feature on "git egress," alongside a paid
human-review console for the supervise flow?
## Summary
- **No scanner reliably detects malicious code.** It's undecidable in
general and adversarial in practice — a capable agent hides a backdoor
from any pattern scanner (and from human reviewers). So the frame is not
"detect malice"; it's **raise the cost, cover the common/obvious cases,
and put a human on the high-leverage ones.**
- **Layered, ranked by ROI:** (1) supply-chain / malicious-dependency
scanning (Socket, OSV-Scanner, GuardDog) — highest ROI, best git fit;
(2) fast heuristic / obfuscation / dangerous-sink scanning
(Semgrep-on-diff) — gitleaks-shaped; (3) **risk-based human gating** via
the existing supervise plane on high-risk file classes; (4) **LLM
semantic diff-review** as a best-effort backstop for novel backdoors.
- **Architecture:** the git-gate's `pre-receive` is *synchronous* (it
blocks the push), so run only fast scanners inline and push heavy
analysis (CodeQL, full LLM review) to an **async post-push CI lane** that
can't hold the developer hostage.
- **Monetization verdict: yes — but the paid unit is the *governed
git-egress review bundle*, not the raw scanner.** The pre-receive
mechanics and the fast OSS scanners stay free (open-core social
contract, same as gitleaks). The sell is the control-plane workflow
around them: **managed semantic review + a web-console human-review flow
+ RBAC + audit retention + cross-run policy.** A bare per-push scan is
borderline "single-run = free" by our own heuristic, and its detection
accuracy is not something to sell on. Sell the *workflow and the
governance*, not the detector.
## The threat: temporal escape
This is the one containment fundamentally can't close. bot-bottle's VM
isolation + egress DLP shrink *live* exfiltration, but the git push
channel launders a payload past all of it: the agent commits code that
looks benign at review time and does its work later, outside the
perimeter — the "blind-XSS"-style temporal escape that both the "3 reasons
sandboxing won't secure your AI agent" talk and Embroidery's "In sandboxes
we (shouldn't) trust" call the sharpest gap. gitleaks gates *secrets* on
this channel; malicious *code* is the uncovered surface, and it's the
behavioral half of the isolation-vs-behavioral split noted in
[`agent-sandbox-landscape.md`](agent-sandbox-landscape.md).
## Why it's fundamentally hard
Distinguishing malicious from legitimate code is undecidable in general
and adversarial in the specific. The underhanded-code contests show humans
hide backdoors from *human reviewers*; a scanner reduces to regex/dataflow
heuristics a motivated agent writes around. So "catch malicious commits"
is the wrong success metric. The right ones: *how much did we raise the
cost*, *did we cover the common and the obvious*, and *did a human see the
dangerous changes before they left*.
## Landscape of git-pluggable approaches (ranked by ROI)
1. **Supply-chain / malicious-dependency scanning — highest ROI.** The
most likely agent-introduced threat is a malicious or typosquatted
*dependency*, not a hand-written backdoor — and it's far more
detectable. **Socket** (behavioral analysis of packages: install
scripts, obfuscation, unexpected network/fs access, typosquats) is the
closest thing to malicious-intent detection that actually works;
**OSV-Scanner** (known-bad DB, fast) and **GuardDog** (PyPI/npm
heuristics) complement it. Trigger only when a commit changes a
lockfile/manifest → block or escalate.
2. **Fast heuristic / obfuscation / dangerous-sink scanning.** **Semgrep**
with a curated ruleset, scanning the *diff* (fast enough for
pre-receive). Catches obfuscation (`eval(atob(...))`, base64/hex blobs,
minified source), exfil primitives (`curl | sh`, reverse shells,
DNS-exfil), and dangerous sinks (`shell=True`, `pickle.loads`, unsafe
`yaml.load`, `child_process.exec`). Tune noisy rules to *escalate*, not
block.
3. **Risk-based human gating — the most robust control, already
half-built.** The git-gate already escalates `# gitleaks:allow`
findings to a supervisor proposal and blocks the push pending approval
(`supervise_gitleaks_allow`, [`git_gate_render.py`](../../bot_bottle/git_gate_render.py)).
Extend the same flow to **high-risk file classes**: any commit touching
CI/build/deploy scripts, auth/crypto code, egress config, or
adding/changing dependencies → route to `./cli.py supervise`. This is
attribution/policy, not detection, and it's the strongest thing here —
a human on exactly the temporal-escape surfaces.
4. **LLM semantic diff-review — the behavioral backstop.** The only
approach with a shot at a novel, benign-looking backdoor: a model
reviews the diff for a backdoor / exfiltration / obfuscated payload /
dangerous behavior. This is the behavioral-detection thesis applied to
the *artifact* (the diff) rather than the agent's reasoning. Real
caveats: false positives and negatives, latency/cost, it can be
prompt-injected by hostile content *in the diff itself*, and it invites
over-trust. Useful, never a guarantee.
**Not for this job:** CodeQL, Trivy, Grype, Bandit. They find *known
vulns and insecure patterns* (bugs), not deliberate backdoors, and the
powerful ones (CodeQL taint) need a build + database — too heavy for a
synchronous gate. They belong in the async CI lane if at all.
## Fit into bot-bottle's git-gate
The `pre-receive` hook today is: gitleaks-scan each ref → escalate
`# gitleaks:allow` findings to supervise → forward to upstream
([`git_gate_render.py`](../../bot_bottle/git_gate_render.py)). The
additions slot in cleanly:
- **Inline (fast), before forward:** a dep-scan phase (on manifest/lockfile
change) and a Semgrep-diff phase. Findings block or open a supervise
proposal, same shape as gitleaks.
- **New supervise tool types** alongside the existing
`egress-block/allow`, `gitleaks-allow`, `egress-token-allow`
([`supervise_types.py`](../../bot_bottle/supervise_types.py)) — e.g. a
`commit-review` proposal for risky-file-class gating and for semantic
review. The supervise plane is already the right abstraction; this is
another *producer* feeding it, and [`supervise_server.py`](../../bot_bottle/supervise_server.py)
(JSON-RPC) is already the console backend.
- **Async lane (heavy):** full LLM review + any CodeQL run out of band
after the push, feeding the same review/audit surface, so the
synchronous gate stays fast.
## The product question: paid feature on git egress?
Restating the open-core line bot-bottle runs on: *give away the
sandbox/runtime, charge for the control plane; single-run/single-node =
free, cross-run aggregation + central enforcement + identity/fleet = paid;
the moat is uniform egress audit + secret custody + policy across
untrusted agents.*
Against that line, the split is clean:
**Free (OSS runtime — the trust funnel):**
- the `pre-receive` gate mechanics and gitleaks;
- wiring the OSS scanners (Socket CLI / OSV-Scanner / Semgrep);
- the CLI supervise flow.
Keeping the raw scanners free is the same social contract as gitleaks and
preserves the bottom-up distribution funnel.
**Paid (the governed git-egress bundle — the control plane):**
- **Managed semantic diff-review** — hosted inference + a curated,
maintained malicious-pattern/policy set. This is *capability* (metered),
not *insurance* — the thing individuals actually pay for. Position it as
**governed code-egress review**, not "we resell inference" (the
monetization notes explicitly warn against reselling compute).
- **The web-console supervise/review flow — the strongest anchor.** Turn
the CLI `./cli.py supervise` approval into a real review surface:
rendered diff + finding context, approve/reject, **who-approved audit
trail, RBAC on approvers, mobile/phone-control** (ties to the
dashboard/vault north star). This is "central enforcement +
identity/fleet = paid" almost verbatim — and it generalizes across
*every* supervise proposal (egress block/allow, gitleaks-allow,
commit-review), so it's worth building for the whole plane, with the
semantic check as one producer.
- **Cross-run governance:** fleet-wide policy for what escalates,
review-decision history/search/export, and drift alerts.
**Why it fits the moat rather than bolting on:** a git push *is* an egress
channel. A semantic review + human approval + audit on it extends the
uniform "egress audit + custody + policy across untrusted agents" wedge to
**code artifacts** — the same product, applied to the one channel gitleaks
only half-covers. That's on-moat, not a detour.
**The honest nuance (don't oversell):** a bare per-push LLM scan is
arguably *free* by the single-run heuristic, and its detection accuracy is
not defensible to charge for. The paid value is the **governance around
it** — the console, RBAC, audit retention, cross-run policy — plus the
managed capability. Sell the *review-and-approve-and-audit workflow*; let
the detector be explicitly best-effort. And per the monetization
guardrail, the "anti-corporate" free crowd must not veto these team
features: the review console + RBAC + audit *are* the monetization.
## Recommendation
1. **Land the free layer first.** Add the dep-scan and Semgrep-diff phases
to `pre-receive`, and extend supervise to risky-file-class gating —
reuses existing machinery, immediate value, stays OSS.
2. **Build the supervise web console** over `supervise_server`'s JSON-RPC
(already the Phase-1 move in the monetization path). This is the paid
anchor and it serves *all* proposal types, not just commit review.
3. **Add managed semantic diff-review as a paid producer** feeding that
console — "governed code-egress review," metered, explicitly
best-effort on detection.
4. **Don't oversell detection.** Market the workflow (review + approve +
audit) and the cross-run policy/RBAC, where the value is real and
