deployment-checklist

A checklist for preparing and monitoring staging or production deployments. It covers code checks, environment settings, builds, rollback plans, health checks, and follow-up monitoring.

In plain words
What is it for?
Use it before deploying application code, database migrations, environment changes, or infrastructure updates.
Why use it?
It reduces common deployment mistakes by requiring tests, configuration checks, and a way to undo the release if something fails.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

deployment-checklist scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Deployment Checklist

Overview

Deployments fail in predictable ways. This checklist prevents the most common causes.

Core principle: Never deploy what you haven't tested. Never deploy without a rollback plan.

Iron Law:

NO DEPLOY WITHOUT ROLLBACK PLAN
If you can't roll back in < 5 minutes, don't deploy.

When to Use

  • Before every production deployment
  • Before staging deployments of critical features
  • When deploying database migrations with code
  • When changing environment configuration
  • When deploying infrastructure changes

Phase 1: Pre-Deploy Validation

Code Readiness

- [ ] All tests passing (zero failures)
- [ ] Test coverage meets threshold (≥ 80% for new code)
- [ ] No TypeScript errors (tsc --noEmit passes)
- [ ] Linting passes (eslint/prettier)
- [ ] No TODO/FIXME in production code paths
- [ ] Security audit passed (npm audit --audit-level=high)
- [ ] PR reviewed and approved
- [ ] Branch up-to-date with main

Build Verification

# Verify build succeeds from clean state
rm -rf dist/ node_modules/.cache
npm run build

# Verify the build output
ls dist/
node dist/main.js --version

Environment Configuration

- [ ] All required env vars documented in .env.example
- [ ] Production env vars set in deployment system
- [ ] No secrets committed to git
- [ ] Config differences between environments documented
- [ ] Feature flags configured correctly

Phase 2: Database Migration (if applicable)

- [ ] Migration files reviewed and approved
- [ ] Migration tested on staging with production data snapshot
- [ ] Rollback migration written and tested
- [ ] Migration is backward-compatible (expand-contract pattern)
- [ ] Estimated migration duration known
- [ ] Maintenance window scheduled if migration > 30s

Migration order: deploy migration → verify → deploy code
# Test migration on staging first
npm run migration:run --env=staging

# Verify migration applied correctly
npm run migration:status

# Verify rollback works
npm run migration:revert --dry-run

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deployment-checklist is a skill published in the GitHub repository JeremyDev87/codingbuddy (31 stars, last pushed 4mo ago), licensed MIT. It adds 33 tokens to every session and 1,490 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
