Use when an execution-layer dev (frontend-dev / backend-dev / ai-agent-dev / ml-engineer / miniapp-dev) has finished feature code + Unit tests and is about to enter code-review. Provides the SIT scope, environment, AC-driven integration walk, and evidence sink (progress/<role>.md). SIT is now a dev-owned step, not a separate QA stage.
Use when apple-dev has finished feature code + Unit tests (Swift Testing) and is about to enter code-review. Provides the Apple SIT scope (xcodebuild test + simulator per declared target), the AC-driven integration walk, APIProtocol-mock discipline, and evidence sink (progress/apple-dev.md). SIT is dev-owned; apple-code-reviewer audits the evidence.
Use when product-lead is about to run a release retrospective after a successful MAJOR or MINOR release push (PATCH skipped). Provides applicability gate, pre-conditions, 7-step execution sequence, anti-patterns, and the verification gate before commit. Pairs with template docs/reviews/retro-_TEMPLATE.md and slash /agf-release-retro.
Use when wiring up or switching between China-domestic LLM providers (DeepSeek, Doubao/Volc Ark, Qwen/DashScope, MiniMax). Provides OpenAI-compatible adapter pattern, env-var contracts, fallback strategy, cost guardrails, and minimum verifications before declaring integration done.
Use when tech-lead is about to record an architecture decision (new tech stack member, deviation from baseline, deployment / observability / auth scheme choice). Provides ADR structure, version-audit appendix format, and "what NOT to ADR" guidance. Replaces ad-hoc copy from ADR-000.
Use when qa-engineer (or miniapp-qa-engineer) is about to publish an E2E or UAT report. Provides the report skeleton, evidence-quality bar, verdict criteria, and hand-off rules. SIT is now dev-owned and lives in progress/<role>.md (see agf-running-sit-tests skill) — this skill does NOT cover SIT reports.
