What is init-rules/api-agent?

A helper that examines API route files, middleware, response formats, and validation patterns. An API is the part of an application that lets other software communicate with it.

Use it during project setup to analyze API endpoints and their supporting code. It checks how requests are processed, validated, and returned.

It gives the setup process a focused review of the API layer instead of treating the whole codebase the same way. It runs only when an API layer is found.

When invoked 725 The whole file, excluding the scripts and references it only reads on demand.

Origin unknown No closer match found in the catalogue.

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	$0.00042	$0.00725
Opus 5.5	$0.00017	$0.00290
Sonnet 5.5	$0.00008	$0.00145
Haiku 4.5	$0.00004	$0.00072

Security

Grade A, and why

init-rules/api-agent 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.
