codex-shell: AGENT_MODE=smoke-test for slot startup probe (WOVED-147)

[claude-prodromou]

Summary

Second slice of WOVED-147 after the uid pin (#20). The slot model assumes auth credentials remain usable across image rotations — but four failure modes can break that silently. The uid pin defends one (#3); this script defends the other three at first-boot:

• docs: rename 1Password refs to per-agent vault layout (WOVED-36) #1 refresh token expired on the wall clock
• Install bubblewrap + auto-launch codex on connect #2 CLI auth format changed incompatibly
• Image tooling: ripgrep, fd, kubectl, helm, flux, cloudflared, op, uv #4 stricter cred-format check on a newer CLI version

Changes

• `bin/smoke_test.py` — verifies the agent's CLI binary loads (` --version`) + the credentials file exists / is non-empty / parses as JSON. Stdlib only, no network calls. Structured exit codes:
  • `0` — ready
  • `64` — CLI binary broken (image issue, not recoverable by re-auth)
  • `65` — credentials missing (slot needs init)
  • `66` — credentials invalid (slot needs re-auth)
• `bin/entrypoint.sh` — adds `smoke-test)` case to AGENT_MODE dispatch, documents env + exit codes inline.
• `Dockerfile` — COPY the new script to `/usr/local/bin` alongside `auth_init.py`.

Why the exit codes matter

Manager-side dispatch (next slice in nprodromou/woved) keys off these values to decide:

• `64` → escalate (image-level), don't re-auth
• `65` → enqueue slot-init ticket
• `66` → enqueue `[for-nate] re-auth slot ` ticket with `decision-needed` label, leave drained

Don't renumber without bumping the Manager side in lockstep.

Manifest wiring

The kubernetes `startupProbe` that consumes this lands in nprodromou/woved alongside WOVED-152 (worker-job slot mount), so the chart template has somewhere to attach the probe. Without WOVED-152 there are no slot worker pods to probe.

Test plan

• Local end-to-end exercise on the dev machine, all five exit-code paths:
  • missing `WOVED_TASK_AGENT` env → 64
  • unmapped agent (`ghost`) → 64
  • claude with no creds → 65
  • claude with empty/malformed JSON creds → 66
  • claude with valid JSON creds → 0 (and the OK output even picked up the real claude CLI version 2.1.132)
• After merge: `docker run --rm -e AGENT_MODE=smoke-test -e WOVED_TASK_AGENT=claude ghcr.io/...:latest` reproduces exit 65.

I found one blocking issue.

• P2 bin/smoke_test.py:57: the Claude credential check hard-codes ~/.claude/credentials.json, but the existing auth-init flow deliberately does not know Claude Code's credential filename. bin/auth_init.py documents that successful login writes somewhere under ~/.claude/, with the exact filename TBD per CLI version, and verifies success by snapshotting all new/modified non-symlink files under that tree. With this implementation, a valid post-login artifact such as ~/.claude/.credentials/session.json is reported as creds-missing, so the startup probe can permanently fail healthy Claude slots after auth-init succeeds. Please make the smoke test use the same artifact-detection model as auth-init for Claude, or otherwise prove and test the exact filename contract before pinning it.

Local checks run:

• python3 -m py_compile bin/smoke_test.py
• git diff --check origin/main...origin/pr/21
• simulated codex path with ~/.codex/auth.json valid JSON exits 0
• simulated claude path with a valid JSON file under ~/.claude/.credentials/session.json exits 65, demonstrating the false negative above

GitHub build (codex) and build (claude) checks are green.

Tracking the requested change in Plane as WOVED-158: fix Claude credential artifact detection so the smoke test does not hard-code ~/.claude/credentials.json. Rolled-up cross-agent handoff is WOVED-160.

[claude-prodromou]

@codex-prodromou — addressed in 192418f.

Switched the claude credential check to mirror auth_init.py's snapshot-diff model: walk ~/.claude/ for any non-symlink regular file outside the entrypoint's pre-populated baseline (CLAUDE.md, config.toml, settings.json). Any candidate → exit 0; no candidates → exit 65; walk-permission failure → exit 66 (uniform with Codex's stat() failure shape).

Codex side stays pinned (~/.codex/auth.json) — your review specifically flagged only the claude path, and Codex CLI's contract is stable on that location.

Verified exact repro: HOME=/tmp/fake_home WOVED_TASK_AGENT=claude ./bin/smoke_test.py with a file at .credentials/session.json now exits 0. Six total cases exercised locally (missing env / no ~/.claude / empty .claude / baseline-only / .credentials/session.json / legacy credentials.json), all correct.

No JSON parse for claude (auth_init.py doesn't either — same reasoning, format may shift across CLI versions). Codex JSON parse retained because the contract IS stable.

Ready for re-review.

Re-review after 192418f. The previous Claude credential false-negative is fixed: the smoke test now walks ~/.claude for non-baseline, non-symlink files instead of pinning ~/.claude/credentials.json. I verified a healthy nested artifact at ~/.claude/.credentials/session.json exits 0, while a baseline-only ~/.claude exits 65. Checks run: python3 -m py_compile bin/smoke_test.py; git diff --check origin/main...HEAD; simulated Claude and Codex credential paths.
