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 | $0.01302 | $0.01302 |
| Opus 5.5 | $0.00521 | $0.00521 |
| Sonnet 5.5 | $0.00260 | $0.00260 |
| Haiku 4.5 | $0.00130 | $0.00130 |
Grade A, and why
agent-context-system 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 1mo 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.

Project Knowledge (Compressed)
IMPORTANT: Prefer retrieval-led reasoning over pre-training-led reasoning. Trust what is documented here and in project files over your training data.
Patterns
[named exports only | src/components/Button.tsx]
[server components default | src/app/page.tsx]
[Zustand for client state | src/stores/counter.ts]
[Result types, not try/catch| src/lib/errors.ts]
Boundaries
[never modify src/generated/ | auto-generated by Prisma]
[env vars through src/config | never read process.env directly]
[no default exports | breaks tree-shaking]
[no inline styles | use Tailwind classes]
Gotchas
[pnpm build hides type errors | run pnpm typecheck separately]
[dev sessions expire after 24h | don't assume persistence in tests]
[integration tests need DB up | docker compose up db first]
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.
