Claude Harness Canary

Run all three groups serially against the currently installed Claude Code. Take no arguments and do not offer group selectors. Target 5–8 minutes, but preserve bounded waits and evidence over that estimate.

Keep this canary core-only, current-Claude-only, interactive-tmux-only, and loaded through --plugin-dir. Never add it to CI, release commands, or $pre-release-review.

Shared probe prerequisite

Reuse the installed $probe lifecycle. Before creating canary state, read its active SKILL.md and require all of these properties:

• real interactive Claude in tmux, never claude -p, Codex, or another PTY;
• no interactive --no-session-persistence;
• tmux pipe-pane starts before any input;
• one bounded readiness phase that detects the trust dialog, accepts it only when present, handles only explicitly recognized startup onboarding, and waits for the normal prompt;
• a unique output-only completion nonce whose complete value is never contiguous in the injected prompt;
• completion accepted only from assistant output after the requested evidence, never prompt echo;
• one bounded wait per canary action;
• teardown with rm -r only after validating the exact scratch path.

If any property is absent, stop before preflight and report:

PREREQUISITE BLOCKED — update the local $probe protocol

Do not recreate generic tmux lifecycle rules locally or hand-roll a fallback. Extend the probe lifecycle only for the multi-action assertions below.

Preflight

Run from the repository root.

1. Resolve the absolute core path at plugins/claude-code-hermit.

2. Record bounded output from:

   claude --version
   claude --help
   tmux -V
   claude auth status --json
   

3. Require current help to expose --plugin-dir, --model, --permission-mode, and --session-id.

4. Require authentication through the default profile. Do not set CLAUDE_CONFIG_DIR.

5. Require these core files:

   • .claude-plugin/plugin.json
   • hooks/hooks.json
   • scripts/lib/harness-command.ts
   • scripts/stop-pipeline.ts
   • scripts/hermit-watchdog.ts
   • scripts/ask-gate.ts
   • scripts/apply-settings.ts
   • scripts/routines.ts
   • scripts/routine-monitor.sh
   • skills/hermit-routines/SKILL.md
