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 | $0.00273 | $0.00273 |
| Opus 5.5 | $0.00109 | $0.00109 |
| Sonnet 5.5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00027 | $0.00027 |
Grade A, and why
ai-native-developer-experience 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 11d 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
Shared agent contract
AGENTS.md, CLAUDE.md and GEMINI.md carry the same portable instructions.
Before taking delivery work, read docs/STATUS.md, then the relevant slice of
docs/ROADMAP.md; inspect open issues, PRs and worktrees and coordinate with the
active owner before starting a competing lane.
Ground changed intent in docs/VISION.md and the relevant versioned requirement.
Use skills/delivery-orchestrator/SKILL.md to maintain the golden thread through
GitHub Issues, acceptance checks, review and release. Load only the role, skill and
artifact sections needed for the current task; do not preload the whole library.
For repository changes read docs/REPOSITORY-CONTRACT.md. Run make check and
fresh, read-only independent adversarial review of the exact candidate before merge.
Before delegation read docs/MODEL-ROUTING.md. Explicit user authority and project
controls govern external actions; skill installation grants no authority.
Reconcile affected requirements, decisions, status, roadmap and changelog as work changes. After an authorised merge, verify integration and safely clean up only this lane's merged branches and clean worktrees. Never overwrite another lane.
Canonical skills live in skills/; .agents/skills/ is a discovery alias.
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.
