<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

**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.
</objective>

<execution_context>
@${CLAUDE_PLUGIN_ROOT}/workflows/plan-phase.md
@${CLAUDE_PLUGIN_ROOT}/references/ui-brand.md
</execution_context>

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

<context>
Phase number: $ARGUMENTS (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.
- `--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)

Normalize phase input in step 2 before any directory lookups.
</context>

<process>
Execute the plan-phase workflow from @${CLAUDE_PLUGIN_ROOT}/workflows/plan-phase.md end-to-end.
Preserve all workflow gates (validation, research, planning, verification loop, routing).
</process>

<output_format>
When planning concludes (PLAN.md files written, plan-checker passed, STATE.md updated), emit a Next Up continuation block following the pattern in `references/continuation-format.md`:

- Show planning status (e.g., `## ✓ Phase N Planned — M plans, K tasks` with brief plan list)
- Emit a `## ▶ Next Up` heading with `/gsd:execute-phase N`
- Use **`` `/clear` then: ``** before the command
- Include a parenthetical: *(`/clear` is safe — `/gsd:resume-work` restores position from `HANDOFF.json` if you change your mind)*
- Add an "Also available:" section: review the plan files, run `/gsd:list-phase-assumptions N`, etc.

Plan-to-execute is a clean boundary — the discuss/research/plan conversation rarely informs execution. Suggesting `/clear` here keeps execution starting with a tight, plan-focused context.
