- agent-sandbox-landscape.md: update agent-safehouse star count (~1.4k →
~1.8k), add HN thread #47301085 link and key discussion notes (creator
framing, Simon Willison observation, top community quote on sandboxing
being THE major challenge), note Apple Container 1.0 stable (Jun 9 2026)
- hn-agent-safety-discourse-july-2026.md: add Agent Safehouse March 12
launch to the sandboxing boom section as context that prefigures the
June–July shift in community tone
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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.
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.
Covers the CVE cascade (DuneSlide, CVE-2026-39861, MCP STDIO injection),
Agentjacking and README-injection attack classes, community opinion
clusters, and a frank assessment of where bot-bottle covers or falls
short against each issue.
