# Discuss Subtask

> Stage ①.c 子任务层 discuss sub-workflow — superpowers brainstorming (≥2 approach / 核心算法 / API contract / 错误成本高)。schema_version: harnessed.workflow.v3 with disciplines_applied (6 default) + tools_available (superpowers-brainstorming + grill-with-docs + grill-me) + 1 phase (01-brainstorm with conditional invokes_tools for spec_ambiguous + no_docs)。Triggered by harnessed CLI `harnessed discuss-subtask --task <text>` or slash command `/discuss-subtask` after `harnessed setup`.

# discuss-subtask workflow (v3)

## Overview

1-phase sub-workflow mapping CLAUDE.md "Stage ①.c 子任务层 — superpowers brainstorming"
onto harnessed runtime (Phase v3.0-3.4 W0.3 — D-04 Stage ① Discuss 三层 + D-05
phase.invokes_tools conditional fire + Pattern A sub-workflow ship)。

| phase | id | upstream | model | capability / invokes_tools | gate |
| ----- | -- | -------- | ----- | -------------------------- | ---- |
| 1 | `01-brainstorm` | superpowers | opus | `{{ capabilities.superpowers-brainstorming.cmd }}` + conditional `invokes_tools[grill-with-docs, grill-me]` | `gate: judgments.subtask-gate.brainstorming.fires` |

## Capability refs

Sister `workflows/capabilities.yaml` entries:
- `superpowers-brainstorming` — Bucket 4 (impl: superpowers, cmd: superpowers:brainstorming)
- `grill-with-docs` — Bucket 1 mattpocock (impl: mattpocock-skills, cmd: /grill-with-docs)
- `grill-me` — Bucket 1 mattpocock (impl: mattpocock-skills, cmd: /grill-me)

## Gate ref

Sister `workflows/judgments/subtask-gate.yaml`:
- `brainstorming.fires` — `subtask.approaches >= 2 or subtask.core_algorithm == true or subtask.has_api_contract == true or subtask.error_cost == 'high'`

## Conditional tool invocation (D-05 invokes_tools)

- `phase.spec_ambiguous == true` → fire `grill-with-docs`
- `phase.spec_ambiguous == true AND phase.no_docs == true` → fire `grill-me`

## Invocation

- Slash command: `/discuss-subtask <text>` (after `harnessed setup`)

## Routing rules

跳过条件 (sister CLAUDE.md "子任务层 ❌ 跳过"):
- 常规 CRUD / 跟现有模式一致
- 单一明显实现 (< 20 行 / 一个文件)
- 标准库直接调用
- bug 修复且已知根因

## How to invoke

Clarification needs real user dialogue, so run this stage directly in THIS session — do NOT
spawn it, and do NOT improvise: follow these steps so the locked spec is persisted for the
execution stages.

1. Evaluate the clarification criteria for "$ARGUMENTS":
   - **Strategic** — new feature / milestone / unclear business scope → gstack `/office-hours` + `/plan-ceo-review`
   - **Phase** — ≥2 open implementation decisions / unclear cross-phase API contract → GSD `/gsd-discuss-phase`
   - **Subtask** — ≥2 distinct approaches / core algorithm / API contract design / high error cost → superpowers brainstorming
2. For each layer that fires, hold the dialogue with the user (use AskUserQuestion for option-style decisions) and lock every open decision.
3. Transparent-skip layers that don't fire — state which were skipped and why.
4. Persist the locked decisions to `.planning/` via planning-with-files (`findings.md` / `task_plan.md`).

Output: a locked spec the execution stages (`/plan` → `/task` → `/verify`) consume without further user input.
