gsd:plan-phase

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.

<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>

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.

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).

<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. </output_format>
