observe
Context-builder for a repo, its team, and its workflow. Scans git history, forge metadata (GitHub via `gh`, Azure DevOps via `az`), CLAUDE.md, CONTRIBUTING.md, CODEOWNERS, PR/issue templates, and ADRs, then writes structured pages into agent-wiki. Use when: user says "observe"/"survey"/"refresh observations"/"brief me"/"investigate <topic>", starting work on an unfamiliar repo, or before a session that needs contributor/workflow context. Produces grounded context for contribute and other downstream skills.
