name: startcycle

description: Linear multi-agent build pipeline with file hand-offs in production_artifacts/, run after /bdbrainstorm or /grill-me. This is the linear variant — no state.json, no repair loop, no dispatcher graph — distinct from startcycle-graph, which adds durable state and automated escalation.

# `/startcycle` — Linear Build Pipeline

A straight-line run through the BDB agent roster. Whoever invokes this skill invokes each step in turn, in order, and every hand-off between steps is a file written under `production_artifacts/`. Nothing else is shared between steps — no memory, no live conversation state, no orchestrator process watching over the run.

## Steps

### 1. Architect

- **Agent**: `architect`

- **Reads**: the goal (or `/bdbrainstorm` / `/grill-me` output), existing architecture.

- **Action**: turns the goal into a system plan with an explicit capability map — module boundaries, dependency direction, what streams the goal actually touches.

- **Writes**: `production_artifacts/00_execution_plan.md`

### 2. TechLead

- **Agent**: `techlead`

- **Reads**: `00_execution_plan.md`.

- **Action**: reviews the plan for module boundaries, dependency direction, and build order. Approves it, or sends it back to Architect once for a revision. This is a gate, not a deliverable — TechLead does not invoke Architect itself; the invoker re-runs step 1 if TechLead rejects.

- **Writes**: no separate file; approval is just the invoker's own record of the gate having passed.

> **Optional — Plan Canvas.** Before or alongside TechLead's gate, the plan can be reviewed in the browser: `aos-plan-canvas open production_artifacts/00_execution_plan.md`, then `aos-plan-canvas await …`. An `approve` verdict is a human confirmation of the gate. This is optional; the pipeline runs unchanged without it. See the `plan-canvas` skill.

### 3. Build (parallel, stream-selective)

Run only the streams the goal actually needs. A plain backend feature does not need step 3a or 3c; a pure copy change does not need 3b. Each stream's `skills:` frontmatter already lists what it should reach for — the invoker passes that list through rather than restating it here.

|---|---|---|---|

3c is for TouchDesigner, show-control, DMX/grandMA3, 3D, or other media-pipeline goals — most goals are not this. Skip it unless the plan actually calls for it.

+ > **Injecting a specific skill.** `/startcycle --skill=<name> <goal>`

+ > (repeatable, quote a name with spaces) forces that skill into this run as

+ > a hard requirement — for a private skill of your own that isn't part of

+ > any build agent's own `skills:` frontmatter. Since this variant has no

+ > dispatcher script or `state.json` to carry it automatically, the invoker

+ > does the work `startcycle-graph`'s script does for you: extract the

+ > `--skill=` flag(s) from the invocation text before anything else runs,

+ > confirm each name resolves to a real `SKILL.md` (under

+ > `~/.claude/skills/<name>/` or this project's own `skills/` tree) — stop

+ > and tell the user if one doesn't, don't silently proceed without it —

+ > note the validated list in `00_execution_plan.md`, and include it as a

+ > **hard requirement, not a suggestion** in each Build stream's dispatch

+ > prompt at step 3. Reviewer (step 4) checks the resulting artifacts for

+ > evidence the skill was actually applied, not just available, and treats

+ > an ignored mandate as a contract-misread finding. See

+ > [`.agents/graph.md`](../../../.agents/graph.md)'s "Mandatory Skill

+ > Injection" section for the full rationale — this is the same mechanic,

+ > just invoker-driven instead of script-driven.

### 4. Reviewer

- **Agent**: `reviewer`

- **Reads**: the artifacts each build stream produced (01/02/03) and the plan's stated contract (`00_execution_plan.md`) — nothing else. Never the goal directly, never a build agent's own claim that it's done; passing that claim through biases the review toward agreement.

- **Action**: adversarial pass — "find what is wrong," never "does this look good." Every finding is classified by fixed precedence:

1. contract misread

2. valid & actionable (blocking)

3. valid trade-off (advisory)

4. noise

- **Writes**: `production_artifacts/review_findings.md`

**The linear pipeline ends here by default.** A plain build or refactor goal is done at step 4 — it does not automatically drag a quality gate and release report behind it.

### 5. Shipping — optional, not a hard-wired terminal step

- **Agent**: `godmode-shipping`

- **Runs only when**: the user explicitly asks for it, or the original goal was itself a release.

- **Action**: lint, typecheck, tests, a11y, SEO — the mechanical quality gate, deliberately separate from Reviewer's adversarial correctness pass.

- **Writes**: `production_artifacts/04_release_report.md`

If the invoker isn't sure whether shipping applies, treat step 4 as the finish line and ask before running step 5.

## Explicit non-goals

This skill deliberately does **not** have:

- `production_artifacts/state.json` or `.agents/state.schema.json`

- `.agents/graph.md` bootstrap

- a dispatcher script or `Workflow` tool call

- a repair loop, an iteration counter, a no-progress guard, or escalation machinery

- agents invoking each other — whoever runs the skill invokes each step in turn; no agent hands off directly to the next

If a run needs any of the above, it needs `startcycle-graph`, not this skill.

---

## Which startcycle do I want?

| Skill | Use when |

|---|---|

| `startcycle` (this one) | Linear, predictable, cheapest of the three. You want a straight run through the agents with file hand-offs and no state machine. |

| `startcycle-graph` | You need the full dispatcher graph: durable `state.json`, a Reviewer repair loop with a no-progress guard, an automated quality gate, escalation to a human, and a resumable record. |

| `startcycle-graph-user` | A small throwaway fan-out (2-4 nodes) in any project, nothing persistent left behind. |

---

## Safety

`git push`, `npm publish`, and `npm version` are blocked by `.claude/hooks/go-gate.mjs` unless the user's immediately preceding message is the literal word `GO`. This skill never pushes on its own — Shipping (step 5) prepares the release report; the invoker still needs a fresh `GO` before anything leaves the machine.
