depot_tools

Triage and analyze LUCI build results (including tests and compile). Fetches a list of test failures by querying ResultDB directly. Can also be used to check results of specific tests. Use this when you need to investigate specific test failures.

A wrapper around the 'bb' (buildbucket) tool designed for low-context agentic usage without overly verbose logs. Good for a high-level overview of builder failures across a patchset, and for surfacing non-test failures (e.g., compile and profile merge failures). For detailed, complete, and actionable test failures, use the 'luci-test-results' skill which queries ResultDB directly for comprehensive information about failures.

Validate skill files specification. Run before committing to ensure SKILL.md files have correct format, required fields, and naming conventions.
