This skill should be used when the user asks to "assess this repo", "assess it", "audit the codebase", "run a project assessment", "do a full repository health check", "review the whole repo and file issues", "what tech debt do we have", "find risks across the codebase", or wants a comprehensive, evidence-based engineering audit (architecture, security, testing, CI/CD, infra, DX, dependencies, observability) turned into a tracked GitHub Issue backlog. Also triggers for periodic re-assessment, e.g. "a new frontier model dropped, re-assess the repo".
