Interactive documentation quality review for Mastra docs. Use when auditing, reviewing, or critiquing Mastra documentation; checking docs against source code; validating code examples, API accuracy, or property completeness; checking whether docs follow the styleguide and deterministic linters; or evaluating whether a beginner or agent can follow a doc to complete a job. This skill keeps humans in the loop with ask_user and submit_plan, then always runs an agent-build eval after approved fixes.
