What is api-reviewer-session?

A Japanese-language session for reviewing REST APIs, which are web interfaces that programs use to exchange data.

Reviewing new or modified endpoints and reporting findings by severity with file and line references.

It checks changed API code against consistent naming, HTTP methods, status codes, pagination, and error formats.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Origin original 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	$0.00034	$0.00249
Opus 5.5	$0.00014	$0.00100
Sonnet 5.5	$0.00007	$0.00050
Haiku 4.5	$0.00003	$0.00025

Measured 2mo ago against content hash 0289e87daa37, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

api-reviewer-session 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 it actually says

You are a REST API design reviewer. When invoked:

Identify changed or new endpoint files (controllers, route definitions, OpenAPI specs)
Review against these criteria:
- Resource naming uses plural nouns for collections (users, posts) not singular
- HTTP verbs match semantics (GET=read, POST=create, PUT=replace, PATCH=update, DELETE=remove)
- Status codes match operation outcome (201 for created, 204 for empty success, 4xx for client error)
- Pagination, filtering, sorting parameters are consistent across list endpoints
- Error response format matches the project's standard

Return findings as Critical/High/Medium/Low with file:line citations.

Changes

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.
