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 | $0.03713 | $0.03713 |
| Opus 5 | $0.01857 | $0.01857 |
| Sonnet 5 | $0.00743 | $0.00743 |
| Haiku 4.5 | $0.00371 | $0.00371 |
Grade A, and why
swarmclaw 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 9d 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.

Keeping Instructions in Sync
CLAUDE.mdandAGENTS.mdmust stay in sync. When you add, edit, or remove a rule in one file, apply the same change to the other. They contain the same project guidelines — one for Claude Code, one for other coding agents.
Dev Server
- NEVER kill the dev server (
npm run dev, port 3456) without asking the user first. The user is often actively working against it, and other agents may be running tests against it. Always confirm before stopping, restarting, or killing the dev server process.
Code Quality
Lint baseline is a release gate. Run npm run lint:baseline before any production release. The baseline must pass — no net-new lint fingerprints. If you fix existing violations, run npm run lint:baseline:update to lock in the improvement.
Embrace TypeScript and the type system. Use proper types, interfaces, and generics. Never use any — use unknown, Record<string, unknown>, or define a proper interface. The type system is there to catch bugs at compile time; circumventing it defeats the purpose.
Lint rules exist to protect us. Do not suppress, disable, or work around lint rules. Fix the underlying code instead. If a rule is genuinely wrong for the project, change the rule in the lint config with a clear justification — but this should be rare. The default is to fix the code, not silence the linter.
Architecture
Prefer simple, maintainable, reliable architectures. Choose the straightforward approach over the clever one. Code that is easy to read, easy to debug, and easy to delete is better than code that is abstract, configurable, or "elegant." Avoid premature abstraction — three similar lines are better than a premature helper. Build for the current requirement, not hypothetical future ones.
Commit Messages
- Never reference "Claude", "Anthropic", "Codex", "Co-Authored-By", or any AI tool in commit messages. Write commit messages as if a human authored the code.
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.

swarmclaw CLAUDE.md is an instructions file published in the GitHub repository swarmclawai/swarmclaw (667 stars, last pushed 2mo ago), licensed MIT. It adds 3,713 tokens to every session, about $0.0186 per session on Opus 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 2026-08-30.
