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 | $0.01771 | $0.01771 |
| Opus 5.5 | $0.00708 | $0.00708 |
| Sonnet 5.5 | $0.00354 | $0.00354 |
| Haiku 4.5 | $0.00177 | $0.00177 |
Grade A, and why
mcp-client-gen AGENTS.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 21d 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Documentation
Start with docs/architecture.md: pipeline, module boundaries, invariants, and which document to read for a change.
- SPECs (
docs/specs/{name}.md, referenced as SPEC-{name}): what the system does —api,generated-client,introspection,cli,config. Specs are the contract; update them in the same commit as the code. - ADRs (
docs/adr/NNN-slug.md, referenced as ADR-NNN): why, and what was rejected — 001 pipeline, 002 OAuth, 003 generator not runtime, 004 schema typing, 005 config and secrets. Revise in place when a decision changes (see000-template.md). local/is gitignored scratch (review handoffs, drafts); never a source of truth.

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.
