Where it applies
Jobs this tool actually does, and the surface each one is exercised on.
Check an API description against an organisation's own design rules before it ships.
coding-agentci-pipeline
The highest-leverage agent use of any tool here — the output is a structured list of findings with paths and line numbers, so the agent can go fix them rather than summarise them.
Prove a third-party API description is fit to build against before generating a client from it.
coding-agent
Author a ruleset that encodes a governance policy, then run it across an estate.
coding-agentci-pipeline
Validate an Arazzo workflow document — currently the most capable option for doing so.
