<cursor_skill_adapter>
## A. Skill Invocation
- This skill is invoked when the user mentions `gsd-plan-phase` or describes a task matching this skill.
- Treat all user text after the skill mention as `{{GSD_ARGS}}`.
- If no arguments are present, treat `{{GSD_ARGS}}` as empty.

## B. User Prompting
When the workflow needs user input, prompt the user conversationally:
- Present options as a numbered list in your response text
- Ask the user to reply with their choice
- For multi-select, ask for comma-separated numbers

## C. Tool Usage
Use these Cursor tools when executing GSD workflows:
- `Shell` for running commands (terminal operations)
- `StrReplace` for editing existing files
- `Read`, `Write`, `Glob`, `Grep`, `Task`, `WebSearch`, `WebFetch`, `TodoWrite` as needed

## D. Subagent Spawning
When the workflow needs to spawn a subagent:
- Use `Task(subagent_type="generalPurpose", ...)`
- The `model` parameter maps to Cursor's model options (e.g., "fast")

<objective>
Create executable phase prompts (PLAN.md files) for a roadmap phase with integrated research and verification.

**Default flow:** Research (if needed) → Plan → Verify → Done

**Research-only mode (`--research-phase <N>`):** Spawn `gsd-phase-researcher` for phase `N`, write `RESEARCH.md`, then exit before the planner runs. Useful for cross-phase research, doc review before committing to a planning approach, and correction-without-replanning loops where iterating on research alone is dramatically cheaper than re-spawning the planner. Replaces the deleted research-phase command (#3042).

**Research-only modifiers:**
- **No flag** — when `RESEARCH.md` already exists, prompt the user to choose `update / view / skip`.
- **`--research`** — force-refresh: re-spawn the researcher unconditionally, no prompt. Skips the existing-RESEARCH.md menu.
- **`--view`** — view-only: print existing `RESEARCH.md` to stdout. Does not spawn the researcher. Cheapest mode for the correction-without-replanning loop. If no `RESEARCH.md` exists yet, errors with a hint to drop `--view`.

**Orchestrator role:** Parse arguments, validate phase, research domain (unless skipped), spawn gsd-planner, verify with gsd-plan-checker, iterate until pass or max iterations, present results.

<runtime_note>
**Copilot (VS Code):** Use `vscode_askquestions` wherever this workflow calls `conversational prompting`. They are equivalent — `vscode_askquestions` is the VS Code Copilot implementation of the same interactive question API. Do not skip questioning steps because `conversational prompting` appears unavailable; use `vscode_askquestions` instead.

<context>
Phase number: {{GSD_ARGS}} (optional — auto-detects next unplanned phase if omitted)

**Flags:**
- `--research` — Force re-research even if RESEARCH.md exists
- `--skip-research` — Skip research, go straight to planning
- `--gaps` — Gap closure mode (reads VERIFICATION.md, skips research)
- `--skip-verify` — Skip verification loop
- `--prd <file>` — Use a PRD/acceptance criteria file instead of discuss-phase. Parses requirements into CONTEXT.md automatically. Skips discuss-phase entirely.
- `--ingest <path-or-glob>` — Use one or more ADR files instead of discuss-phase. Parses locked decisions + scope fences into CONTEXT.md automatically. Skips discuss-phase entirely.
- `--ingest-format <auto|nygard|madr|narrative>` — Optional ADR parser format override (`auto` default).
- `--reviews` — Replan incorporating cross-AI review feedback from REVIEWS.md (produced by `/gsd-review`)
- `--text` — Use plain-text numbered lists instead of TUI menus (required for `/rc` remote sessions)
- `--mvp` — Vertical MVP mode. Planner organizes tasks as feature slices (UI→API→DB) instead of horizontal layers. On Phase 1 of a new project, also emits `SKELETON.md` (Walking Skeleton). Can be persisted on a phase via `**Mode:** mvp` in ROADMAP.md.

Normalize phase input in step 2 before any directory lookups.
