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-starter-kit 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — project constitution (TEMPLATE)

Claude Code reads this first every session. The four @-imports below auto-load the working rules, the running handover, the lessons database, and the task board — always in context, re-injected from disk after every compaction. Keep this file lean (< ~200 lines); push sometimes-relevant knowledge into .claude/skills/ and deterministic checks into .claude/hooks/. Fill in the <...> blanks.

@rules.md @HANDOVER.md @LESSONS.md @TASKS.md

Session protocol (rules.md §9)

  • Start: run /keel-continue (cross-checks the loaded memory against PLAN.md + git, then RESUMES half-done work, TAKES the lane's next assigned item via the comprehension gate, or reports IDLE) — or by hand: read the TOP block of HANDOVER.md + LESSONS.md + TASKS.md ## Now + recent git log; pick ONE ## Now item; verify tests pass before new work.
  • During: the moment a rule / must-run test / gotcha / failed approach is agreed or discovered — ask "shall I note this?" and append it to LESSONS.md immediately (don't wait for compaction).
  • End (or before compact): /keel-handover (new HANDOVER block) · delete done TASKS items · commit with approval. If any memory file exceeds its cap → /keel-distill. About to compact manually? Run /keel-compact — it bundles all of the above, verifies freshness, then hands off to /compact.
  • When compacting, always preserve: the list of modified files, open TASKS.md ## Now items, test commands, and any agreement not yet written to LESSONS.md (write it there first).

Architecture (summary)

Key decisions (ADRs in docs/adr/)

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.
