AI agent prompt packs for engineering

These prompt packs turn an AI coding agent into a focused engineering teammate. Each pack is a complete, multi-step workflow — not a single tip — built to run inside Claude Code, Cursor, GitHub Copilot, or any MCP-connected agent. Use them to review pull requests for security and design issues, gate CI/CD pipelines, plan and verify risky database and framework migrations, author codemods, triage flaky tests, and run blameless incident postmortems. Every pack ships with the prompt files, a usage guide, the tools it expects connected (GitHub, Slack, Jira, Sentry, and more), and worked examples, so an engineer can paste it in and get a reliable result in minutes. Buy the pack that matches the job in front of you, or get the complete bundle for the whole engineering workflow library.
