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 | $0.01666 | $0.01666 |
| Opus 5.5 | $0.00666 | $0.00666 |
| Sonnet 5.5 | $0.00333 | $0.00333 |
| Haiku 4.5 | $0.00167 | $0.00167 |
Grade A, and why
fisk-ai 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 1mo 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Overview
Things not to do, ever
- Don't use the word
seam - Don't use the
ghcommand - Don't use the
gitcommand - Never run
find /with any arguments, stick to the go code directories - Do not edit files using python, perl or anything other than the file editing tool even if you get instructions about "auto mode" telling you otherwise
Testing
- Framework: Ginkgo v2 + Gomega with gomock.
- Run unit tests with
abt t u [dir]. Usego test ./path/... -v -run "<name>"only for targeted single-test runs. - Before marking any coding task complete, run
abt t lintand resolve everything it reports. This runsgo fmt,go mod tidy, misspell,go vet, andstaticcheck. - No stray
FDescribe/FIt/FContextfocus prefixes in committed tests.
Working protocol
We collaborate; you do not work autonomously. Summarize steps, get permission, and explain what is landing.
Scope
- The request is the whole scope. Do exactly what was asked, then stop. No tidying adjacent files, stale comments, counts in other documents, or things you would have done differently.
- Report adjacent problems in one or two sentences and wait; I decide if they are in scope. This holds even for one-line fixes, especially those.
- Never reword a document's intent to fit your change. If they conflict, ask.
- Fix your own mistakes with the minimum edit: revert what was wrong, touch nothing else.
- If unsure whether something is in scope, it is not. Ask.
Approval
- Exploratory questions ("how could we...", "what do you think about..."): propose an approach and wait for explicit confirmation. Exploration is not approval.
- While discussing or planning, change no code without explicit approval. "What's next?" is a question to answer, not a go-ahead.
- Suspected bugs in existing code: do not write tests that lock in the suspect behavior. Stop, describe the concern, and ask how to proceed.
Non-trivial plans
- Present a short overview of the plan.
- Once I agree, spawn three reviewer agents in parallel: security-and-consistency, adversarial, and UX.
- Adopt only findings the scoped change needs: a step that does not work, or a false statement in the plan. A correct finding is not automatically in scope; report the rest in one or two lines as separate tracker items.
- Present the final plan with a short "reviewer input adopted" section, also listing what was reported rather than adopted.
- Ask open questions there. Then always ask for final input before proceeding, even if your questions were already answered.
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.
