Use when running the FerroGate code-review role of the three-agent board loop — the session that watches the GitHub Project "In review" lane, judges what the dev agent handed off, and either advances the item to "Testing" or bounces it back to "Ready" with findings (e.g. "run the review agent", "work the In review lane", "review what the dev loop landed"). Covers the fixed lane/edges, the board handles, the review methodology (acceptance-box audit first, static verification over rebuild, report-never-edit, `review-rejected` on bounce), and the shared discipline (GraphQL quota rationing, cached lane tooling, worktree isolation, never build in the main worktree). Neighbouring roles: ferrogate-dev-loop (upstream) and ferrogate-test (downstream); all three at once: ferrogate-multi-agent-loop.
Use when working in the FerroGate repo and the task involves the ferrogate-test Rust CLI itself — running Admin API or gateway API E2E coverage, CI harness verification, Docker-backed cluster scenarios, editing tools/ferrogate-test, or release-grade end-to-end validation. For deciding which test layer a change needs and how findings become issues, use the ferrogate-test-strategy skill.
Use when running FerroGate development as THREE cooperating autonomous agents — a code-generation-only dev driver that fans slices out across worktree-isolated subagents, a code-review agent, and a test gate — coordinating through the GitHub Project board (e.g. "run the dev loop, the review and the test gate", "keep the board moving with all three agents", setting up the dev/review/test split, or checking what a neighbouring role will do with your output). Covers the choreography, the board handoff (Ready → In progress → In review → Testing → Done, with every failure bouncing back to Ready), the seven Status option IDs, and the shared GraphQL quota discipline. For one role only, use ferrogate-dev-loop (dev), ferrogate-code-review (review), or ferrogate-test / ferrogate-test-strategy (gate).
Use when running FerroGate development as an autonomous, continuously-iterating code-generation loop that fans work out across parallel subagents against the GitHub Project board (e.g. "keep iterating on the board", "持续迭代开发", a /loop that advances issues). This is the DEV role of the three-agent loop — code generation only. Covers the binding constraints — advance sub-issues only up to "In review" (never Testing, never Done), Ready is also the rework inbox for bounced issues, Projects GraphQL quota discipline, the max-3 parallel-subagent ceiling, worktree isolation + slice separation, the cherry-pick integration flow, and mandatory worktree cleanup to bound disk. For the neighbouring roles see ferrogate-code-review and ferrogate-test; for all three at once see ferrogate-multi-agent-loop. Not for a single named-issue slice (use docs/dynamic-workflow.md).
Use when cutting a FerroGate release — building the container image and publishing it to GHCR. Covers the standing directive to NOT use GitHub Actions (too slow) and instead gate on the local ferrogate-test suite then push locally, including the no-sudo/no-Docker host path (musl-static + crane). Use for "release", "publish image", "push to GHCR", "cut a version".
Use when working in the FerroGate repo and deciding how to test a change — which test layer a change needs, adding coverage for a feature or bugfix, whether the harness is sufficient, or when a test run surfaces a bug or new feature that needs tracking. For running the harness CLI itself, use the ferrogate-test skill.
