Cds plan phase

<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> @$HOME/.claude/cds-workflow/workflows/plan-phase.md @$HOME/.claude/cds-workflow/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 /cds-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 @$HOME/.claude/cds-workflow/workflows/plan-phase.md end-to-end. Preserve all workflow gates (validation, research, planning, verification loop, routing). </process>
