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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01006 | $0.01006 |
| Opus 5.5 | $0.00402 | $0.00402 |
| Sonnet 5.5 | $0.00201 | $0.00201 |
| Haiku 4.5 | $0.00101 | $0.00101 |
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 ofHANDOVER.md+LESSONS.md+TASKS.md ## Now+ recentgit log; pick ONE## Nowitem; 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.mdimmediately (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 ## Nowitems, test commands, and any agreement not yet written toLESSONS.md(write it there first).

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.

claude-code-starter-kit CLAUDE.md is an instructions file published in the GitHub repository muratsilahtaroglu/claude-code-starter-kit (9 stars, last pushed 1mo ago), licensed MIT. It adds 1,006 tokens to every session, about $0.0040 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
