Preflight

description: Production readiness checklist — env, health, security.
argument-hint: "[--strict] [--url <deployment-url>]"
---

Run a production readiness checklist before deploying. Checks environment variables, health endpoints, error monitoring, CORS, rate limiting, security headers, performance, database, and DNS/SSL configuration. Catches the things that work in dev but break in prod.

## Progress Tracking

This skill uses TaskCreate for progress tracking. Before starting work:
1. Create one task per major step using TaskCreate
2. Set each task to `in_progress` when starting it (TaskUpdate)
3. Mark `completed` when done
4. Write deliverables to files, not inline — inline text is for communication only

## Content Loading

Load each step through the fetch command (handles caching, decryption, and auth):

```bash
"$HOME/.composure/bin/composure-fetch.mjs" skill shipyard preflight {step-filename}
```

**Do NOT read cache files directly** — they are encrypted at rest. Always use the fetch command above.
