sgc

Use after implementation to run independent code review - dispatches reviewer agents based on task level, ensures author-reviewer separation

Use for the L2+ browser-QA gate. Real-browser mode (Playwright Chromium) is opt-in (--browse / SGC_QA_REAL=1); by default runs a stub returning concern (never rubber-stamps). Writes verdict + findings to reviews/{task}/qa/.

Use when starting any conversation - establishes SGC commands, routes tasks to appropriate skills, and enforces system invariants

Use to capture knowledge from solved problems - extracts structured solution documents via 4 specialized agents with dedup enforcement

Use when requirements are unclear, before planning - clarifies goals, constraints, and acceptance criteria through structured questioning

Use when starting any non-trivial task - classifies task level (L0-L3), runs appropriate planning agents, produces intent document and execution plan

Use when ready to release - verifies all evidence, runs ship gate, handles deployment, triggers compound janitor

Use to check current task state, view decision history, browse knowledge base statistics, or resume from a checkpoint

Use when executing an approved plan - implements with TDD discipline, systematic debugging, worktree isolation, and progress tracking
