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 | $0.00373 | $0.00373 |
| Opus 5 | $0.00187 | $0.00187 |
| Sonnet 5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
aontu 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 6d 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.
What it actually says
CLAUDE.md
See AGENTS.md for the full contributor and agent guide:
repository layout, build/test commands, the shared test/spec/*.tsv
suite, and TypeScript/Go parity conventions.
Fundamentals are recorded in ADR.md: ADR-001 (TS/Go full parity via the shared spec) and ADR-002 (100 % coverage in both, every exclusion justified). Do not reverse those without a new ADR entry.
Quick reference:
- TypeScript (
ts/) is the canonical implementation; the Go port (go/) is kept in parity for the subset it implements. ts/distandts/dist-testare committed — rebuild after editingts/srcorts/test(make build-ts).- Shared behaviour lives in
test/spec/*.tsvand is run by bothts/test/spec.test.tsandgo/spec_test.go. make testruns both suites;make covchecks the ADR-002 floor.- Documentation edits follow docs/STYLE-GUIDE.md
(Diátaxis placement, voice, banned phrases, snippet directives);
ts/test/docs.test.tsenforces it — every tagged snippet tested or skipped with a reason. - Forward-looking work is the capability review in
docs/capability-review/(G1–G10, design) plusdocs/capability-review/progress.md(the register of what has landed). A phase's row in the register changes in the same commit that changes its status — see AGENTS.md, "The capability-review progress register".
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.
