msd-core/get-shit-done/workflows/plan-phase.md

Create executable phase prompts (PLAN.md files) for a roadmap phase with integrated research and verification. Default flow: Research (if needed) -> Plan -> Verify -> Done. Orchestrates gsd-phase-researcher, gsd-planner, and gsd-plan-checker agents with a revision loop (max 3 iterations).

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting.

@~/.claude/get-shit-done/references/ui-brand.md </required_reading>

1. Initialize

Load all context in one call (paths only to minimize orchestrator context):

INIT=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs init plan-phase "$PHASE")

Parse JSON for: researcher_model, planner_model, checker_model, research_enabled, plan_checker_enabled, nyquist_validation_enabled, commit_docs, phase_found, phase_dir, phase_number, phase_name, phase_slug, padded_phase, has_research, has_context, has_plans, plan_count, planning_exists, roadmap_exists.

File paths (for <files_to_read> blocks): state_path, roadmap_path, requirements_path, context_path, research_path, verification_path, uat_path. These are null if files don't exist.

If planning_exists is false: Error — run /gsd:new-project first.

2. Parse and Normalize Arguments

Extract from $ARGUMENTS: phase number (integer or decimal like 2.1), flags (--research, --skip-research, --gaps, --skip-verify).

If no phase number: Detect next unplanned phase from roadmap.

If phase_found is false: Validate phase exists in ROADMAP.md. If valid, create the directory using phase_slug and padded_phase from init:

mkdir -p ".planning/phases/${padded_phase}-${phase_slug}"

Existing artifacts from init: has_research, has_plans, plan_count.

3. Validate Phase

PHASE_INFO=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs roadmap get-phase "${PHASE}")

If found is false: Error with available phases. If found is true: Extract phase_number, phase_name, goal from JSON.

4. Load CONTEXT.md

Check context_path from init JSON.

If context_path is not null, display: Using phase context from: ${context_path}

If context_path is null (no CONTEXT.md exists):

Use AskUserQuestion:

• header: "No context"
• question: "No CONTEXT.md found for Phase {X}. Plans will use research and requirements only — your design preferences won't be included. Continue or capture context first?"
• options:
  • "Continue without context" — Plan using research + requirements only
  • "Run discuss-phase first" — Capture design decisions before planning

If "Continue without context": Proceed to step 5. If "Run discuss-phase first": Display /gsd:discuss-phase {X} and exit workflow.

5. Handle Research

Skip if: --gaps flag, --skip-research flag, or research_enabled is false (from init) without --research override.

If has_research is true (from init) AND no --research flag: Use existing, skip to step 6.

If RESEARCH.md missing OR --research flag:

Answer: "What do I need to know to PLAN this phase well?"

**Project skills:** Check .agents/skills/ directory (if exists) — read SKILL.md files, research should account for project skill patterns

Handle Researcher Return

• ## RESEARCH COMPLETE: Display confirmation, continue to step 6
• ## RESEARCH BLOCKED: Display blocker, offer: 1) Provide context, 2) Skip research, 3) Abort

5.5. Create Validation Strategy (if Nyquist enabled)

Skip if: nyquist_validation_enabled is false from INIT JSON.

After researcher completes, check if RESEARCH.md contains a Validation Architecture section:

grep -l "## Validation Architecture" "${PHASE_DIR}"/*-RESEARCH.md 2>/dev/null

If found:

1. Read validation template from ~/.claude/get-shit-done/templates/VALIDATION.md
2. Write to ${PHASE_DIR}/${PADDED_PHASE}-VALIDATION.md
3. Fill frontmatter: replace {N} with phase number, {phase-slug} with phase slug, {date} with current date
4. If commit_docs is true:

node ~/.claude/get-shit-done/bin/gsd-tools.cjs commit-docs "docs(phase-${PHASE}): add validation strategy"

If not found (and nyquist enabled): Display warning:

⚠ Nyquist validation enabled but researcher did not produce a Validation Architecture section.
  Continuing without validation strategy. Plans may fail Dimension 8 check.

6. Check Existing Plans

ls "${PHASE_DIR}"/*-PLAN.md 2>/dev/null

If exists: Offer: 1) Add more plans, 2) View existing, 3) Replan from scratch.

7. Use Context Paths from INIT

Extract from INIT JSON:

STATE_PATH=$(echo "$INIT" | jq -r '.state_path // empty')
ROADMAP_PATH=$(echo "$INIT" | jq -r '.roadmap_path // empty')
REQUIREMENTS_PATH=$(echo "$INIT" | jq -r '.requirements_path // empty')

11. Handle Checker Return

• ## VERIFICATION PASSED: Display confirmation, proceed to step 13.
• ## ISSUES FOUND: Display issues, check iteration count, proceed to step 12.

12. Revision Loop (Max 3 Iterations)

Track iteration_count (starts at 1 after initial plan + check).

If iteration_count < 3:
