+
+- **Status:** Draft
+- **Author:** didericis
+- **Created:** 2026-06-03
+- **Issue:** #171
+
+## Summary
+
+At agent launch time, present the operator with a curses modal to optionally
+set a human-readable label and color for the agent before it launches. The
+modal pre-fills the label with the current agent name pattern (e.g.
+`implementer-a3f9`) and leaves color unset; Enter with no changes accepts
+those defaults. Store both in the bottle's `metadata.json`. Display the label —
+rendered in the chosen ANSI color — in `cli list active` output, replacing
+the bare manifest key. Inject the label and color into the in-container
+`claude.json` as `name` / `color` so Claude Code can surface them in its own
+harness when upstream support lands.
+
+## Problem
+
+`cli list active` identifies each running instance by its manifest agent key
+(e.g., `implementer`) plus a random slug suffix. When an operator runs three
+`implementer` bottles simultaneously — one each for three different repos —
+the output shows:
+
+```
+docker  a3f9  implementer  egress,pipelock
+docker  b81c  implementer  egress,pipelock
+docker  d220  implementer  egress,pipelock
+```
+
+There is no way to tell which bottle is working on which task without attaching
+to each one in turn. The slug is opaque; the manifest key is shared. Operators
+working a multi-bottle session resort to keeping a mental map of slug→task,
+which breaks the moment they switch windows.
+
+## Goals / Success Criteria
+
+1. After the operator selects an agent (picker or CLI argument) and backend,
+   a curses modal appears before the preflight. The modal pre-fills the label
+   with `<agent_name>-<slug_suffix>` (the same pattern currently shown in
+   `list active`). No color is pre-selected.
+2. In the modal, any printable keystroke immediately replaces the pre-filled
+   label and starts building the new name. Backspace edits normally. Enter
+   at any point confirms — accepting the pre-fill if nothing was typed, or
+   the in-progress text otherwise.
+3. After the label field is confirmed, the modal presents color selection:
+   a list of the 16 ANSI color names the operator can navigate with arrow
+   keys, or Enter / Esc with no selection to skip color entirely.
+4. `label` and `color` are stored in `BottleMetadata` and written to the
+   bottle's `metadata.json`. Both fields default to `""` (empty / unset).
+5. `ActiveAgent` carries `label` and `color`; `enumerate_active()` reads them
+   from `metadata.json`.
+6. `cli list active` shows the label when non-empty (falling back to
+   `agent_name`). If a non-empty color is set and the terminal supports it,
+   the label is prefixed with the appropriate ANSI escape code and reset
+   afterward.
+7. `BottleSpec` carries `label` and `color`; both backends' `prepare` steps
+   copy them into `BottleMetadata`.
+8. `ClaudeAgentProvider.provision_plan()` writes `label` → `"name"` and
+   `color` → `"color"` into the generated `claude.json`. Fields are omitted
+   when empty.
+9. `cmd_start` calls `name_color_modal` after backend selection and before
+   `_launch_bottle`; passes `label` / `color` into `BottleSpec`.
+10. All existing unit tests stay green; no new tests are required for this
+    change (the label/color fields are thin plumbing with no branching logic
+    worth unit-testing beyond the already-tested metadata read/write path).
+
+## Non-goals
+
+- Showing the agent label inside the Claude Code TUI (status line, terminal
+  title, custom header). That requires upstream Claude Code / codex support.
+  Writing to `claude.json` is best-effort scaffolding for when that lands.
+- Validating or constraining label content beyond the 64-byte printable cap.
+- Editing the label or color of an already-running bottle.

+
+### BottleSpec changes
+
+```python
+@dataclass(frozen=True)
+class BottleSpec:
+    manifest: Manifest
+    agent_name: str
+    copy_cwd: bool
+    user_cwd: str
+    identity: str = ""
+    label: str = ""   # operator-chosen display name; defaults to agent_name at render time
+    color: str = ""   # one of the 16 ANSI color names, or "" for terminal default
+```
+
+`label` and `color` default to `""` so all existing callers remain valid with
+no changes.
+
+### BottleMetadata changes
+
+Add two new fields with backward-compatible defaults:
+
+```python
+@dataclass
+class BottleMetadata:
+    identity: str
+    agent_name: str
+    cwd: str
+    copy_cwd: bool
+    started_at: str
+    compose_project: str
+    backend: str
+    label: str = ""
+    color: str = ""
+```
+
+`metadata.json` written by older bot-bottle versions won't have these keys;
+`read_metadata` already uses `dict.get` with defaults, so existing slugs load
+cleanly with `label=""`, `color=""`.
+
+### ActiveAgent changes
+
+```python
+@dataclass(frozen=True)
+class ActiveAgent:
+    backend_name: str
+    slug: str
+    agent_name: str
+    started_at: str
+    services: tuple[str, ...]
+    label: str = ""
+    color: str = ""
+```
+
+`enumerate_active()` copies `label` and `color` out of `BottleMetadata` when
+constructing each `ActiveAgent`. The smolmachines backend gets the same
+additions for symmetry.
+
+### `cli list active` rendering
+
+The current row format is tab-separated:
+`{backend}\t{slug}\t{agent_name}\t{services}`
+
+With labels it becomes:
+```python
+display_name = a.label if a.label else a.agent_name
+```
+
+Color is rendered via ANSI escape codes. A small `_ansi_color(color_name)`
+helper returns the appropriate escape prefix for the 16 named colors, or `""`
+when the name is unrecognised or the terminal doesn't support color
+(`NO_COLOR` env var or `not sys.stdout.isatty()`).
+
+The 16 ANSI color name → escape mapping:
+
+| Name | ANSI code |
+|------|-----------|
+| `black` | `\033[30m` |
+| `red` | `\033[31m` |
+| `green` | `\033[32m` |
+| `yellow` | `\033[33m` |
+| `blue` | `\033[34m` |
+| `magenta` | `\033[35m` |
+| `cyan` | `\033[36m` |
+| `white` | `\033[37m` |
+| `bright-black` | `\033[90m` |
+| `bright-red` | `\033[91m` |
+| `bright-green` | `\033[92m` |
+| `bright-yellow` | `\033[93m` |
+| `bright-blue` | `\033[94m` |
+| `bright-magenta` | `\033[95m` |
+| `bright-cyan` | `\033[96m` |
+| `bright-white` | `\033[97m` |
+
+Reset is `\033[0m`. Applied around the label substring only.
+
+### The label+color modal
+
+A single curses modal (`name_color_modal` in `bot_bottle/cli/tui.py`) handles
+both label and color in two sequential steps within the same window.
+
+```python
+label, color = name_color_modal(default_label=f"{agent_name}-{slug_suffix}")
+```
+
+**Step 1 — label.** The window renders:
+
+```
+  Name agent
+  ──────────────────────────────────────
+  implementer-a3f9
+  ──────────────────────────────────────
+  [any key] edit  [Enter] confirm
+```
+
+The pre-filled text is shown in the input field. Any printable keystroke
+immediately clears the pre-fill and starts a new name from that character
+(first-keystroke-replaces semantics). Subsequent keystrokes append normally.
+Backspace edits from the right. Enter confirms — accepting the pre-fill if
+the field was never edited, or the typed text otherwise.
+
+**Step 2 — color.** After confirming the label, the window transitions to:
+
+```
+  Name agent
+  ──────────────────────────────────────
+  implementer-a3f9  ← confirmed label
+  ──────────────────────────────────────
+  Color (optional)
+  > (none)
+    red
+    green
+    blue
+    …
+  ──────────────────────────────────────
+  [↑↓] move  [Enter] select  [Esc] skip
+```
+
+The list starts with `(none)` selected. Arrow keys move the cursor; Enter
+confirms the highlighted choice; Esc or `q` skips color. Each color name in
+the list is rendered in its own curses color so the operator can preview the
+palette.
+
+The function returns `(label, color)` — both strings, `color` is `""` when
+`(none)` is selected or the step is skipped.
+
+### Slug suffix for the default label
+
+The default label is `<agent_name>-<slug_suffix>`, where `slug_suffix` is the
+last four characters of the slug (the same short hash shown in `list active`).
+
+In `cmd_start` the slug is minted inside `prepare`, after the modal appears.
+The modal is therefore called with the manifest agent key as a fallback
+(`default_label=agent_name`). Once `prepare` returns the plan (which contains
+the slug), the `BottleSpec` is not reconstructed — the label entered by the
+operator is already in the spec. The full `<agent_name>-<slug_suffix>` form is
+only available for display in subsequent `list active` calls once the bottle
+is running.
+
+### Claude Code config injection
+
+Per PRD 0050, the `claude.json` trust-marker file is written by
+`ClaudeAgentProvider.provision_plan()` in
+`bot_bottle/contrib/claude/agent_provider.py`. Add `label: str = ""` and
+`color: str = ""` keyword parameters to `provision_plan()` on both the
+`AgentProvider` ABC and `ClaudeAgentProvider`, and to the
+`agent_provision_plan()` shim in `agent_provider.py`. Both `prepare.py`
+modules pass `spec.label` / `spec.color`; `CodexAgentProvider` accepts the
+params and ignores them.
+
+In `ClaudeAgentProvider.provision_plan()`:
+
+```python
+payload = {
+    "hasCompletedOnboarding": True,
+    "theme": "dark",
+    "bypassPermissionsModeAccepted": True,
+    "projects": claude_projects,
+}
+if label:
+    payload["name"] = label
+if color:
+    payload["color"] = color
+claude_config.write_text(json.dumps(payload, indent=2) + "\n")
+```
+
+## Implementation chunks
+
+Two PRs, each independently mergeable.
+
+### Chunk 1 — schema + storage
+
+- Add `label: str = ""` and `color: str = ""` to `BottleSpec`,
+  `BottleMetadata`, and `ActiveAgent`.
+- `docker/prepare.py` and `smolmachines/prepare.py`: copy `spec.label` /
+  `spec.color` into `BottleMetadata`; pass them to `agent_provision_plan()`.
+- `docker/enumerate.py` and smolmachines equivalent: copy `metadata.label` /
+  `metadata.color` into `ActiveAgent`.
+- Add `label: str = ""` and `color: str = ""` keyword params to
+  `AgentProvider.provision_plan()` (ABC), `ClaudeAgentProvider.provision_plan()`
+  (uses them in the `claude.json` write), and the `agent_provision_plan()` shim.
+  `CodexAgentProvider` accepts the params and ignores them.
+- `cmd_list`: update `list active` row to use `label` when non-empty, with
+  ANSI color escape codes.
+- No prompt changes; no UI changes. All existing behavior is identical.
+
+### Chunk 2 — modal
+
+- `bot_bottle/cli/tui.py`: add `name_color_modal(default_label)` implementing
+  the two-step curses window described above.
+- `cmd_start`: call `name_color_modal(default_label=agent_name)` after backend
+  selection and before `_launch_bottle`; pass `label` / `color` into
+  `BottleSpec`.
+
