Read from the package source without running it. The installed server may list more.

comber_api_check
Exercise an API surface with Comber: an OpenAPI spec, a GraphQL endpoint, or a recorded HAR. Reports contract drift, error responses, and broken operations. Read-only by default.
comber_check
Crawl a web app / site / SaaS surface with Comber and report broken clicks, dead ends, console errors, and broken links. Read-only by default (does not submit forms or trigger mutations). Great to run against a preview/staging URL before merging. Optional LLM finding-judge only runs if ANTHROPIC_API_KEY is set in the environment.
comber_report
Read the full findings list from a previous comber run. Pass the runDir returned by comber_check / comber_api_check.
