The user's digital twin browser — a persistent headless Chromium that inherits their real Arc/Chrome cookies and browses the web as them. Use nightcrawl whenever the user wants to interact with a website as themselves: "go to", "open this site", "navigate to", "read this page", "search on [site]", "log in to", "download from", "scrape", "crawl", "what does this page say", "fill out this form", "check if this site blocks us", or any task involving a URL or web page. Also use it to LOG THE USER IN as themselves — "log me in", "sign in as me", "use my saved password", "get me into my account" — via `autofill-login`, which submits the browser's OWN saved password through Engine R (the real Arc browser) without ever reading it; and to FILL FORMS — "fill in my details/email/address", "autofill this signup" — via `autofill` from a local non-secret profile vault. Cookies already imported from the user's real browser persist across sessions in ~/.nightcrawl/ — never re-import. Stealth (CDP patches, UA, optional CloakB
Load task PRD and project specs before writing code. Use before implementation, refactors, or harness changes.
Post-bug-fix retrospective — classify root cause, identify prevention, write the lesson into specs. Use after fixing any non-trivial bug, when a task involving 'fix', 'bug', 'debug', or 'diagnose' is being finished, or when the user asks 'what went wrong', 'why did this break', 'root cause', or 'lessons learned'. Also use when the lifecycle hook reminds you to run break-loop.
Resume the current Codex harness task. Use when returning to a task, when the user asks what state we are in, or when the conversation has shifted between planning, implementation, and checking.
Finish a Codex harness task after implementation, checking, spec updates, and rollout verification.
Analyze a codebase and generate durable spec files from existing patterns, architecture, and conventions. Use to initialize or refresh .codex/spec/ for a project. Also use when the lifecycle hook reminds you to run spec-bootstrap, when a project has empty or template-only specs, when the user says 'generate specs', 'initialize specs', 'bootstrap specs', or 'make the codebase context durable'.

Verify the current task without turning the main session into a diagnostic dump.
Identify changed files:
git status --short
git diff --name-only
Load check context:
python3 scripts/codex_harness.py task agent-context <task> check
Run task-specific tests and focused syntax checks.
For harness changes, run:
python3 install.py
Use deeper diagnostics only when the focused check fails:
python3 scripts/codex_harness.py context --dashboard
python3 ~/.codex/harness/bin/verify_all_codex_harness.py --deep
python3 ~/.codex/harness/bin/verify_all_codex_harness.py --state-audit
Report product/task outcome first. Mention harness internals only if they block the requested work or explain a failed verification.
