# discuss-phase workflow (v3)

## Overview

2-phase sub-workflow mapping CLAUDE.md "Stage ①.b Phase 层 — GSD /gsd-discuss-phase 灰色澄清"
onto harnessed runtime (Phase v3.0-3.4 W0.2 — D-04 Stage ① Discuss 三层 + Pattern A
sub-workflow ship)。

| phase | id | upstream | model | capability / invokes | gate / artifacts |
| ----- | -- | -------- | ----- | -------------------- | ---------------- |
| 1 | `01-gsd-discuss` | gsd | sonnet | `{{ capabilities.gsd-discuss-phase.cmd }}` | `gate: judgments.phase-gate.gsd-discuss-phase.fires` |
| 2 | `02-persist` | planning-with-files | haiku | `{{ capabilities.planning-with-files.cmd }}` + `invokes: /plan` | `artifacts_expected: [findings.md, knowledge.md]` |

## Capability refs

Sister `workflows/capabilities.yaml` entries:
- `gsd-discuss-phase` — Bucket 2 (impl: gsd, cmd: /gsd-discuss-phase)
- `planning-with-files` — Bucket 4 (impl: claude-code-plugin, cmd: /plan)

## Gate refs

Sister `workflows/judgments/phase-gate.yaml`:
- `gsd-discuss-phase.fires` — `phase.open_decisions >= 2 or phase.has_cross_phase_data_flow == true or phase.scope_days > 1`

## Invocation

- Slash command: `/discuss-phase <num>` (after `harnessed setup`)

## Routing rules

跳过条件 (sister CLAUDE.md "Phase 层 ❌ 跳过"):
- 单一明确子任务
- 跟前 phase 同 module 同 pattern
- < 1 天工作量
- bug 修复且已有最小复现

## How to invoke

Use the Bash tool to run:

```bash
echo "$ARGUMENTS" | harnessed run discuss-phase --task-stdin
```

If `$ARGUMENTS` is empty, run `harnessed run discuss-phase` (no stdin pipe).

After completion, the Bash output prints a `Next:` hint on stderr suggesting the next stage. Decide whether to invoke based on conversation context — the hint is informational, not prescriptive.
