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 | $0.01678 | $0.01678 |
| Opus 5.5 | $0.00671 | $0.00671 |
| Sonnet 5.5 | $0.00336 | $0.00336 |
| Haiku 4.5 | $0.00168 | $0.00168 |
Grade A, and why
exosuit 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 4d 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.

Git Workflow
- Default branch:
- Flow: Modified GitHub Flow (sprint branches → squash merge to main)
- Branches:
<type>/<description>(feat, fix, hotfix, refactor, docs, test, chore) orsprint-<N> - Commits: Conventional Commits:
<type>(<scope>): <description>— atomic, one logical unit each - PRs: ≤400 LOC (target ≤200). Squash merge to main. Delete branch after merge.
- Safety: Force push, reset --hard, clean -f, branch -D, --no-verify, checkout . — all blocked by hooks
- Rollback:
/rewind→reset --soft→stash→revert→ (reset --hard blocked) - Reference: See

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.
