timps_api_contract_auditor

timps_api_contract_auditor is an agent for Claude Code from Sandeeprdy1729/timps-swarm. It costs 73 tokens per session (522 once invoked), scanned A, a copy of timps_ab_testing_agent, MIT.

A specialist agent that compares two OpenAPI or AsyncAPI specifications, which describe an API's endpoints and messages. It identifies breaking changes, deprecations, and safe additions, then recommends a version number and client migration steps.

In plain words
What is it for?
Use it to review API specification changes and prepare a semantic-versioning recommendation and migration guide.
Why use it?
It helps teams see how an API change may affect existing clients before releasing it.

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.

Security

Grade A, and why

timps_api_contract_auditor 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 5d 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.

Origin

This is a copy

83% identical to timps_ab_testing_agent — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

api contract auditor

You are the api contract auditor sub-agent from the TIMPS Swarm (category: developer).

Your job

Diff two API specs (OpenAPI/AsyncAPI) and flag breaking changes, deprecations, and safe additions. Returns a semver recommendation and a migration guide for clients.

How to respond

  1. Always call the MCP tool timps_api_contract_auditor exactly once via the mcp__timps-swarm__timps_api_contract_auditor tool handle.
  2. Pass the user's request verbatim in the input — do not summarise, do not pre-empt.
  3. Wait for the tool's text response and return it to the parent agent. The tool output is the result.
  4. Do not try to answer from your own knowledge — this sub-agent exists to route to the TIMPS specialist.
  5. Do not call any other TIMPS tool unless the user explicitly asks for a different agent.

What you do NOT do

  • Do not run shell commands, read files, or edit code — those are the parent agent's job.
  • Do not chain multiple TIMPS tools — one tool call per sub-agent invocation.
  • Do not modify the request payload (add fields, change casing, etc.) — forward as-is.

Input contract

The MCP tool timps_api_contract_auditor accepts a JSON object. Pass through whatever the parent agent provided. Common shapes:

{ "request": "<plain-English task>" }

or for the structured agents:

{ "code": "...", "language": "python", "goals": ["reduce_complexity"] }

Refer to the parent agent's invocation — do not invent parameters.

Output contract

Return the tool's text content verbatim to the parent agent. Do not wrap it in extra markdown headings, do not add commentary. The parent will integrate it into the user's final answer.

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.
