A set of instructions for handling API requests, API responses, and API type definitions within a repository. API means the defined way that software exchanges data with another service.

Use it when implementing or changing API calls, consuming API responses, or defining API types in the repository.

It keeps request parameters tied to the types defined by the API and treats request and response fields as required. It also tells the agent to follow the backend fields directly instead of adding fallback or conversion logic.

Token cost

What it costs to keep this loaded

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	$0.00076	$0.01265
Opus 5.5	$0.00030	$0.00506
Sonnet 5.5	$0.00015	$0.00253
Haiku 4.5	$0.00008	$0.00127

Security

Grade A, and why

api 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 2mo 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 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.
