Load [Mode Rules](references/mode-rules.md) and [Reporting](references/reporting.md). - **Review Retrospective**: inspect recent history, usually latest 30 commits. Identify commit-message habits, weak traceability, missing Spec/Test/Risk evidence, oversized or mixed-scope commits, spec-doc patterns, and rework signals. Load [Mode Rules](references/mode-rules.md) and [Reporting](references/reporting.md). ## Entry and Routing 1. Identify the mode from the user's request or the current review surface. 2. Read repo instructions first: nearest `AGENTS.md`, plugin manifests, and the target spec or diff. 3. Gather bounded local evidence using [Evidence Commands](references/evidence-commands.md). 4. Apply the relevant contract: - Spec Preparation: [Spec Con...
