Most prompt packs are one-liners you try once and forget. This is a short, practical reference for the parts of Claude Code that change how much you ship: briefing it on a codebase, making it plan before it edits, getting it to debug from the root cause instead of guessing, having it review its own work, and handing a session off cleanly when context runs out.
Copy a template, fill in the bracketed parts, paste it in.
What's inside (17 templates)
- CLAUDE.md starter templates: solo project, team repo, monorepo
- Planning-first prompts: spec-first, phased "don't surprise me" changes, architecture tradeoffs
- Systematic debugging loop: root cause before fix, plus what to send when a fix didn't work
- Self-review prompts: strict-reviewer pass, security pass, simplification pass
- Subagent and parallel work: fan-out research, fork-and-verify
- Test-driven development loop
- Refactor and simplify prompt
- Session handoff templates: end-of-session handoff, resuming from one
- Quick-reference cheat sheet: which template to reach for in which situation

Format
One Markdown file (about 1,900 words) that opens in any editor, GitHub, or Obsidian. The prompts also work with other coding agents, though they're written with Claude Code in mind.
