/plan

Create PLAN.md with phase-based breakdown for tasks, spikes, and bugs.

Usage

/plan 001                    # Create plan for issue 001 (auto-detect project)
/plan 001 --project coordinatr  # Explicit project
/plan SPIKE-003              # Plan for a spike (creates exploration plans)
/plan 003 --second-opinion   # Get peer review from Gemini CLI before finalizing

Issue Type Detection

Execution Flow

For Task/Bug

1. Load Context:

``bash Read: ideas/[project]/issues/###-/TASK.md (or BUG.md) Read: spaces/[project]/docs/specs/.md (if implements: field exists) Glob: spaces/[project]/docs/adrs/ADR-.md Glob: resources/research/.md ``

If the issue has an implements: field, load that specific spec section: ``bash Read: spaces/[project]/docs/specs/required-features.md # Extract relevant section ``

1. Cross-Project Pattern Search:

``bash # Search other projects for similar implementations Grep: spaces/*/src/ for relevant patterns ``

Include relevant references in plan: ```markdown ## Related Implementations

Found similar patterns in other projects: - spaces/yourbench/src/auth/clerk.ts - Clerk auth setup - spaces/coordinatr/src/lib/session.ts - Session handling ```

1. Library Documentation (automatic for integrations):

MANDATORY when task involves: - Installing/configuring external libraries or SDKs - Framework integrations (auth providers, databases, APIs) - Third-party services (Clerk, Stripe, AWS services, etc.)

Process: ```bash # 1. Resolve library ID mcpcontext7resolve-library-id: {libraryName}

# 2. Fetch current documentation mcpcontext7query-docs: {context7CompatibleLibraryID}

# 3. Search for recent patterns/best practices WebSearch: "{library} {framework} integration 2026" ```

Document findings: ```markdown ## Library Documentation Validation

{Library Name} (validated YYYY-MM-DD): - Current version: X.Y.Z - Key integration patterns: [summary] - Recommended approach: [based on current docs] ```

1. Generate Plan:

- Break work into logical phases - Each phase has clear deliverables - Include checkpoints between phases - Add "Done When" criteria

1. Write PLAN.md:

- Present phases, estimated effort, dependencies - Include "Library Documentation Validation" section (if applicable) - Include "Second Opinion Analysis" section (if requested)

1. Commit Suggestion:

- Ask: "Commit PLAN.md to ideas repo? (yes/no)"

For Spike (Exploration)

1. Load Context: Read SPIKE.md (questions, success criteria, time box)

1. Gather Approaches:

- Ask: "How many approaches to explore?" → N - For each: "Describe approach N?"

1. Generate: Create PLAN-N.md for each approach

1. Commit Suggestion: Ask to commit all plan files

Task Plan Example

# Implementation Plan: 001 Research Auth Patterns

## Overview
Research authentication patterns for Coordinatr's multi-tenant architecture.

## Phase 1: Survey Existing Solutions

### 1.1 - Research Auth Libraries
- [ ] Review Better Auth documentation
- [ ] Compare with Auth.js and Lucia
- [ ] Document trade-offs

### 1.2 - Multi-Tenant Patterns
- [ ] Research team-based auth patterns
- [ ] Review how Slack, Linear handle it
- [ ] [CHECKPOINT] Summary document complete

## Phase 2: Architecture Proposal

### 2.1 - Draft Architecture
- [ ] Create architecture diagram
- [ ] Document token strategy
- [ ] Define permission model

### 2.2 - Review
- [ ] Self-critique against requirements
- [ ] [CHECKPOINT] Architecture doc complete

## Done When
- [ ] Auth library recommendation documented
- [ ] Architecture proposal in ideas/coordinatr/docs/
- [ ] Trade-offs and risks identified

Second Opinion Feature

What: Optional peer review from Gemini CLI before finalizing plans.

Usage: Pass --second-opinion flag to trigger Gemini review with Context7 validation.

Process:

1. Send plan to Gemini CLI for review
2. Validate each recommendation against Context7 docs
3. Claude makes final decision on each:

- ✅ ACCEPT: Recommendation validated AND improves plan - ⚠️ MODIFY: Good idea but needs adjustment - ❌ REJECT: Invalid or not applicable

1. Document all decisions in "Second Opinion Analysis" section

Requirements:

• Gemini CLI installed and functional
• --second-opinion flag explicitly passed

Graceful degradation: If Gemini unavailable, proceeds with Claude-only plan.

Workflow

/spec → /issue → /plan {ID} → (work phases) → /complete {ID}
                    ↓
          Load spec section from implements: field

Creates:

• Task/Bug: ideas/{project}/issues/###-*/PLAN.md
• Spike: ideas/{project}/issues/###-*/PLAN-1.md, PLAN-2.md, etc.
