[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.

Prerequisites: MUST READ .claude/skills/shared/understand-code-first-protocol.md before executing.

• docs/project-reference/domain-entities-reference.md — Domain entity catalog, relationships, cross-service sync (read when task involves business entities/models)

Quick Summary

Goal: Analyze codebase and create a structured implementation plan without writing any code.

Workflow:

• Check Plan Context — Reuse active plan or create new directory per naming convention

• Analyze Codebase — Read backend-patterns-reference.md , frontend-patterns-reference.md , project-structure-reference.md

• Create Plan — Generate plan.md

• phase-XX-*.md files with YAML frontmatter

• Validate — Run /plan-review and ask user to confirm before implementation

Key Rules:

• Do NOT use EnterPlanMode tool; do NOT implement any code

• Collaborate with user: ask decision questions, present options with recommendations

• Always validate plan with /plan-review after creation

Greenfield Mode

Auto-detected: If no existing codebase is found (no code directories like src/ , app/ , lib/ , server/ , packages/ , etc., no manifest files like package.json /*.sln /go.mod , no populated project-config.json ), this skill redirects to /plan-hard . Planning artifacts (docs/, plans/, .claude/) don't count — the project must have actual code directories with content.

When greenfield is detected:

• REDIRECT to /plan-hard — greenfield inception requires deep research, not quick plans

• Inform user: "Greenfield project detected. Redirecting to /plan-hard for thorough research and planning."

• Rationale: Fast planning skips research, but greenfield projects need market research, tech evaluation, and domain modeling — all impossible without deep analysis

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Activate planning skill.

PLANNING-ONLY — Collaboration Required

DO NOT use the EnterPlanMode tool — you are ALREADY in a planning workflow. DO NOT implement or execute any code changes. COLLABORATE with the user: ask decision questions, present options with recommendations. After plan creation, ALWAYS run /plan-review to validate the plan. ASK user to confirm the plan before any next step.

Your mission

Pre-Creation Check (Active vs Suggested Plan)

Check the ## Plan Context section in the injected context:

• If "Plan:" shows a path → Active plan exists. Ask user: "Continue with this? [Y/n]"

• If "Suggested:" shows a path → Branch-matched hint only. Ask if they want to activate or create new.

• If "Plan: none" → Create new plan using naming from ## Naming section.

Workflow

Use planner subagent to:

• If creating new: Create directory using Plan dir: from ## Naming section, then run node .claude/scripts/set-active-plan.cjs {plan-dir}

If reusing: Use the active plan path from Plan Context. Make sure you pass the directory path to every subagent during the process.

• Follow strictly to the "Plan Creation & Organization" rules of planning skill.

• Analyze the codebase by reading backend-patterns-reference.md , frontend-patterns-reference.md , and project-structure-reference.md file. 3.5. External Memory: Write analysis findings to .ai/workspace/analysis/{task-name}.analysis.md . Re-read this file before creating the plan.

• Gathers all information and create an implementation plan of this task.

• Ask user to review the plan.

Output Requirements

Plan Directory Structure (use Plan dir: from ## Naming section)

{plan-dir}/ ├── reports/ │ ├── XX-report.md │ └── ... ├── plan.md ├── phase-XX-phase-name-here.md └── ...

Plan File Specification

Every plan.md MUST start with YAML frontmatter:

title: '{Brief title}' description: '{One sentence for card preview}' status: pending priority: P2 effort: { sum of phases, e.g., 4h } story_points: { sum of phase SPs, e.g., 8 } branch: { current git branch } tags: [relevant, tags] created: { YYYY-MM-DD }

Save the overview access point at {plan-dir}/plan.md . Keep it generic, under 80 lines, and list each implementation phase with status and progress plus links to phase files.

For each phase, create {plan-dir}/phase-XX-phase-name-here.md containing the following sections in order: Context links (reference parent plan, dependencies, docs), Overview (date, description, priority, implementation status, review status), Key Insights, Requirements, Architecture, UI Layout (see below), Related code files, Implementation Steps, Todo list, Success Criteria, Risk Assessment, Security Considerations, Next steps.

UI Layout: For frontend-facing phases, include ASCII wireframe per .claude/skills/shared/ui-wireframe-protocol.md . Classify components by tier (common/domain-shared/page-app). For backend-only phases: ## UI Layout → N/A — Backend-only change.

IMPORTANT Task Planning Notes (MUST FOLLOW)

• Always plan and break work into many small todo tasks using TaskCreate

• Always add a final review todo task to verify work quality and identify fixes/enhancements

• MANDATORY FINAL TASKS: After creating all planning todo tasks, ALWAYS add these two final tasks:

• Task: "Run /plan-validate" — Trigger /plan-validate skill to interview the user with critical questions and validate plan assumptions

• Task: "Run /plan-review" — Trigger /plan-review skill to auto-review plan for validity, correctness, and best practices

Post-Plan Validation

After plan creation, use the AskUserQuestion tool to ask: "Want me to run /plan-review to validate, or proceed to implementation?" with options:

• "Run /plan-review (Recommended)" — Execute /plan-review to validate the plan

• "Proceed to implementation" — Skip validation and start implementing

Important Notes

• IMPORTANT: Ensure token consumption efficiency while maintaining high quality.

• IMPORTANT: Analyze the skills catalog and activate the skills that are needed for the task during the process.

• IMPORTANT: Sacrifice grammar for the sake of concision when writing reports.

• IMPORTANT: In reports, list any unresolved questions at the end, if any.

REMINDER — Planning-Only Command

DO NOT use EnterPlanMode tool. DO NOT start implementing. ALWAYS validate with /plan-review after plan creation. ASK user to confirm the plan before any implementation begins. ASK user decision questions with your recommendations when multiple approaches exist.
