preflight

$npx mdskill add hrconsultnj/claude-plugins/preflight

Runs a production readiness checklist to catch issues before deployment, ensuring environment stability.

  • Helps developers identify and fix problems that work in development but break in production environments.
  • Integrates with environment variables, health endpoints, error monitoring, CORS, rate limiting, and security headers.
  • Uses a step-by-step process to check configuration, health, security, performance, database, and DNS/SSL settings.
  • Presents results through a report and writes tasks for actionable follow-up based on the findings.

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.

## Content Loading

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

```bash
"~/.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.

SkillDescription
app-architectureComplete architecture guide for building features from database to UI. Routes to frontend/, fullstack/, mobile/, backend/, or sdks/ based on detected stack. Covers decomposition, multi-tenant isolation, auth model, query patterns, and component patterns.
audit-depsFocused dependency CVE audit — reports vulnerabilities with version info and safe upgrade commands.
backlogManage the tasks-plans/ workspace — add items to backlog, ideas, or reference. Process queued work. Organize by topic, not flat dumps.
build-graphBuild or update the code review knowledge graph, generate the visualization, and open it. Run this first to initialize, or let hooks keep it updated automatically.
calibrateCalibrate test bench — detect test framework, read existing test conventions, generate .claude/testbench.json config. Query Context7 for test framework reference docs. Run once per project.
ci-generateGenerate CI/CD workflow from detected stack. GitHub Actions, GitLab CI, or Bitbucket Pipelines. Includes lint, typecheck, test, build, and deploy stages.
ci-validateValidate CI/CD workflow files. Runs actionlint for GitHub Actions, checks for common mistakes, and reports issues with fix suggestions.
code-organizerRestructure a messy project into conventional file layout based on detected framework. Analyzes, plans, executes with import updates, and verifies.
deps-checkCheck dependency health -- known CVEs, outdated packages, unsafe versions. Recommends the highest safe version, not just "latest". Blocks Critical CVEs via Composure commit gate.
