Plan Phase

plan-phase workflow (v3)

Overview

2-phase sub-workflow mapping CLAUDE.md "Plan 阶段 — GSD + planning-with-files" onto harnessed runtime (Phase v3.0-3.4 W0.5 — D-04 Stage ② Plan 二层 + D-15 planning-with-files claude-code-plugin /plan + Pattern A sub-workflow ship)。

| phase | id | upstream | model | capability / invokes | artifacts | | ----- | -- | -------- | ----- | -------------------- | --------- | | 1 | 01-gsd-plan | gsd | sonnet | {{ capabilities.gsd-plan-phase.cmd }} | (Wave A research + Wave B planner + Wave C plan-checker) | | 2 | 02-persist | planning-with-files | haiku | {{ capabilities.planning-with-files.cmd }} + invokes: /plan | artifacts_expected: [task_plan.md, progress.md] |

Capability refs

Sister workflows/capabilities.yaml entries:

• gsd-plan-phase — Bucket 2 (impl: gsd, cmd: /gsd-plan-phase)
• planning-with-files — Bucket 4 (impl: claude-code-plugin, cmd: /plan;

requires the planning-with-files Claude Code plugin to be installed via the Claude Code plugin marketplace; outputs: task_plan.md + progress.md + findings.md)

Stage ② 铁律 — dual capability

GSD /gsd-plan-phase orchestrate (Wave A research → Wave B planner → Wave C plan-checker) → planning-with-files /plan 持久化 (plugin 真生成 task_plan.md + progress.md, NOT fs.writeFile self-impl per D-15 Q-AUDIT-5a claude-code-plugin reframe)。

Invocation

• Slash command: /plan-phase (after harnessed setup)

Output artifacts

• task_plan.md — 主任务清单 + 文件路径 + 依赖 + 验收标准
• progress.md — phase 进度跟踪 + cross-session 恢复
• (findings.md 由 discuss-* sub-workflow 产出, 此处不重复)

How to invoke

!harnessed checkpoint intent plan-phase

> The banner above (when present) means this invocation is REGISTERED with the engine (an intent marker) — not yet compliant: the steps below (prompt → spawn → checkpoint complete) resolve it, and a per-turn `` reminder persists until they run.

The numbered sequence below is the state machine — execute it with Bash. Do NOT improvise an equivalent flow from the Overview above: freelancing bypasses the engine (no ledger, no evidence guard). harnessed gives you the spawn-ready prompt; YOU spawn the subagent with a CC-native Task / Agent tool (keeps the session responsive + lets clarification round-trips reach the user).

Do NOT pipe to harnessed run plan-phase — that is the CI/headless path (in-process SDK spawn that blocks the session inside Claude Code).

1. Bash: harnessed prompt plan-phase --task "$ARGUMENTS" --json → parse {prompt, max_iterations, model}.
2. Spawn a CC-native subagent (Task / Agent tool) with that prompt + model, wrapped in the ralph-loop plugin: /ralph-loop "" --max-iterations --completion-promise "COMPLETE". If the plugin is absent, use the native goal gate instead (Claude Code 2.1.139+ / Codex): /goal "this subtask is delivered: the subagent's final output contains verbatim COMPLETE; or stop after turns" then spawn the subagent and let the goal evaluator drive re-spawns until it clears. If /goal is unavailable too, self-loop: spawn → check output for COMPLETE → re-spawn with prior output appended (up to max_iterations). Set the goal only at the leaf subtask level — /goal is single-slot per session and a nested goal overwrites the outer one.
3. If the output contains STATUS: NEEDS_CLARIFICATION + a question list: STOP, relay them verbatim via AskUserQuestion, append the answers to the spec, then re-spawn the same sub.
4. On COMPLETE: Bash harnessed checkpoint complete plan-phase --summary "". The evidence guard runs here (fail-CLOSED): if a declared artifacts_expected file is missing it exits non-zero — re-spawn to produce it before treating the sub as done.
