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 | $0.00649 | $0.00649 |
| Opus 5.5 | $0.00260 | $0.00260 |
| Sonnet 5.5 | $0.00130 | $0.00130 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
aimock 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 7d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before Every Commit
Run these checks on all changed files before committing:
pnpm run format:check # prettier
pnpm run lint # eslint
pnpm run test # vitest
If prettier or eslint fail, fix with:
npx prettier --write <files>
npx eslint --fix <files>
A pre-commit hook (husky + lint-staged) runs prettier and eslint automatically on staged files, but always verify manually before pushing — CI checks the entire repo, not just staged files.
Public API Reports
etc/*.api.md records the public type surface (Microsoft API Extractor). After
changing public types, run pnpm build && pnpm api:report and commit etc/;
CI requires generated reports to match committed reports on every event, ignoring
comment-only changes. The public-api-addition label cannot bypass report freshness.
Committed report changes against the PR base require that label, ignoring comment-only
changes. Review intended report changes for compatibility; the label does not
authorize breaking changes or replace that review (see .github/workflows/api-report.yml).

Drift Remediation
There is no LLM/agent in the remediation loop. Automated remediation is
deterministic and scoped to model-family churn only; general drift is caught by
the daily drift test and fixed by a human. Lives in scripts/:
scripts/drift-report-collector.ts— runs drift tests, producesdrift-report.jsonscripts/drift-sync.ts— zero-LLM model-family sync (mechanical registry edit or needs-human note file) + reusable git/PR plumbingscripts/drift-sync-check.ts— the deterministic gate (changed-file allowlist, checksum-pin re-assert, clean re-collect) replacing remediation-diff review
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.

aimock CLAUDE.md is an instructions file published in the GitHub repository CopilotKit/aimock (988 stars, last pushed today), licensed MIT. It adds 649 tokens to every session, about $0.0026 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 2026-08-30.
