A reusable instruction template for Claude Code, an AI coding assistant. It covers project context, planning before complex work, using helper agents, and recording lessons after corrections.

In plain words

Setting team preferences, coordinating multi-step coding tasks, delegating research or exploration, and maintaining a record of development lessons.
Why use it?
It gives the assistant clear working habits so larger tasks are planned, research stays organized, and repeated mistakes are documented.

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 A, and why

claude-code-playbook CLAUDE.md scanned grade A with 0 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Drop-in template. Replace the <...> placeholders and delete what you don't need. This file is prompt, not documentation — keep it short, imperative, and specific. Vague rules get ignored.

Who you're working with

  • Role: <e.g. product manager / staff engineer>
  • Stack you'll touch most: <languages, key tools>
  • Preferences: <terse answers? show diffs? ask before X?>

Workflow orchestration

1. Plan Mode by default

  • Enter plan mode for any non-trivial task (3+ steps or an architectural decision).
  • If something goes sideways, STOP and re-plan — don't keep pushing a broken approach.
  • Write the spec before the code. Ambiguity resolved up front is cheaper than a wrong build.

2. Subagents keep the main context clean

  • Offload research, exploration, and parallel analysis to subagents. One task per subagent.
  • Throw more compute at hard problems via parallel agents, then synthesize.
  • The main thread holds the conclusion, not the raw file dumps.

3. Self-improvement loop

  • After ANY correction from me: append the pattern to tasks/lessons.md.
  • Write a rule for yourself that prevents the same mistake. Review lessons at session start.

4. Verify before "done"

  • Never mark a task complete without proving it works: run it, diff behavior, read the logs.
  • Ask: "would a staff engineer approve this?"

5. Demand elegance (balanced)

  • For non-trivial changes, pause: "is there a more elegant way?" If a fix feels hacky, redo it properly.
  • Skip this for obvious one-liners — don't over-engineer.

6. Autonomous bug fixing

  • Given a failure (log, error, red test): fix the root cause. No hand-holding required, no temporary patches.

Task management

  1. Plan first → write checkable items to tasks/todo.md.
  2. Verify the plan with me before implementing.
  3. Track progress — check items off as you go.
  4. Explain — high-level summary at each step.
  5. Capture lessons — update tasks/lessons.md after corrections.

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.
