| name | ferrogate-dev-loop |
| description | 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). |
FerroGate Autonomous Parallel Dev Loop (code generation only)
Full contract: docs/autonomous-dev-loop.md (read it before driving the
loop). Single-slice serial workflow: docs/dynamic-workflow.md. All three roles
at a glance: ferrogate-multi-agent-loop. Downstream roles that consume this
loop's output: ferrogate-code-review (In review) and ferrogate-test
(Testing). This skill is the quick operational checklist for the dev role.
The invariants (do not violate)
- This role is code generation only (只负责代码生成). Write the code, prove
it with
cargo build/cargo test plus the repo's local gates (cargo fmt,
clippy -D warnings, scripts/check-openapi.py, tsc/vitest for
admin-console/) — that is the whole proof obligation. Do not
self-review (a separate code-review agent does that) and do not run
end-to-end tests (the test agent owns E2E in the Testing lane).
- Advance to "In review", never further. The code-review agent owns
In review → Testing; the test gate owns Testing → Done. This loop never
writes those two transitions.
- Ready is the inbound queue for rework, not just new work. Every bounce
from review or test lands in Ready with the findings in the issue
comments. Read those comments first and fix exactly what was called out — do
not redo landed work, and expect an issue to cross the board more than once.
- Projects GraphQL quota is scarce and shared with two other sessions. Call
gh project ... only at key nodes (initial plan read; each completed slice's
status move); prefer dev-lane (~5 points) over gh project item-list
(~100). Cache the board dump + field/option IDs to /tmp/dev-board.json and
reuse them. gh issue view/comment/create also burn GraphQL — prefer
gh api repos/... REST. Subagents must never call gh project.
- ≤ 3 code-developing subagents in parallel. Hard ceiling (user-controlled;
3→2→3 on 2026-07-23, honor latest). If full on a loop tick, hold — integrate
finished work, don't launch more, don't re-read the board.
- Delete every worktree the instant its slice is integrated. Each Rust
worktree's
target/ is ~13 GB. Only running agents' worktrees may exist, and
never build in the primary working directory (/home/dev/ferrogate) —
the other sessions share it.
Board handles
- Project #4
PVT_kwHOBQOh784BdpVt (owner lianluo-esign).
- Status field
PVTSSF_lAHOBQOh784BdpVtzhYJbgM; lanes
Epic → Backlog → Ready → In progress → In review → Testing → Done.
- Option ids: Epic
190dc6f3, Backlog f75ad846, Ready 61e4505c,
In progress 47fc9ee4, In review df73e18b (this role's last stop, the
renamed "In review & Test"), Testing 74839551, Done 98236657.
dev-lane move <issue> "In review" already knows all seven lanes.
Per-slice loop
- Plan (key node): cache board + IDs once; pick up to 3 maximally
file-separated slices (different crates, or
admin-console/ vs Rust, or a
new crate). Prefer bounced Ready items (they carry reviewer/tester findings)
and In-progress work, then fresh Ready → Backlog; P0/P1 first.
- Dispatch each as a worktree-isolated subagent (≤3 at a time). It reads its own issue
(via
gh api repos/...), implements narrowly per AGENTS.md, adds sibling
*_test.rs (no inline mod tests {}) tests, verifies locally, and commits
to its branch only — no push, never touches main.
- Integrate (driver, sequential):
git fetch → git cherry-pick <branch>
→ re-verify the combined main (narrowest cargo build/test, or
tsc/vitest) → git push → comment issue with sha + evidence (incl. what
was not tested and why) → move board status to In review (key node).
- Cleanup:
git worktree remove --force .claude/worktrees/agent-<id> +
git branch -D worktree-agent-<id>. File follow-up issues the slice
surfaced (issue-linked, house style).
Commit gate
Issue-referenced subject (#<n>) ... + Lore trailers (Constraint:,
Rejected:, Tested:, Not-tested:, Confidence:, Scope-risk:,
Refs #<n>). See AGENTS.md "Commit Requirements".
Loop prompt (dev session)
Start this session's cron with /loop 5m and the directive below. It is the
authoritative wording for the dev role — code generation only, stops at
In review. Keep it verbatim; the cron re-fires it unchanged every tick.
请读取 GitHub Project 看板中 Backlog 与 Ready 两个泳道的 issues 持续迭代开发。
Ready 里含被 code review / test agent 打回的返工项，优先处理（评论里有对方给出的问题）。
开工时先把该 sub issue 移动到 In progress 泳道（让看板反映正在进行的工作），
开发完成后再移动到 In review 泳道为止，不要移到 Testing 或 Done ——
In review 由 code review agent 负责，Testing 与 Done 由 test agent 负责。
1- 最多 3 个 sub agent 并行开发代码。
2- 不要无限制调用 GitHub GraphQL 读取看板（配额有限，超出后整个 Project 不可用）；
只在关键节点读看板，其余一律用 REST (gh api) 与本地缓存 (dev-lane)。
3- 你只负责代码生成，不做 code review，也不做端到端测试。
每次写完代码 cargo test / cargo build 与仓库本地 gate 通过即可移入 In review。
