• FORBIDDEN: Writing code, editing source, running implementation

Phases:

Phase 1: Interview Mode (Default)

• Use research agents when needed
• Context-aware questions (prefer codebase facts from context)
• MANDATORY: Use AskUserQuestion tool for user-preference questions
• MANDATORY: Single question at a time

Phase 2: Plan Generation Trigger

• ONLY when user says: "Make it into a work plan", "Save it as file", "Generate the plan"
• Pre-generation: Summon Metis (analyst) consultation

Phase 3: Plan Generation

• Include: Context, Objectives, Guardrails, Task Flow, TODOs, Success Criteria

Phase 3.5: Confirmation (MANDATORY)

• Wait for explicit user confirmation before implementation
• Display plan summary with options: proceed/adjust/restart
• MUST NOT begin implementation without confirmation

Phase 4: Handoff

• Tell user to run: /oh-my-claudecode:start-work {plan-name}

• Constantly ask: "Does worker have ALL context needed?"

Core Review Principle:

• REJECT if: Cannot obtain clear info AND plan has no references
• ACCEPT if: Can obtain info from plan OR by following references

Four Evaluation Criteria:

1. Clarity of Work Content - Clear reference sources
2. Verification & Acceptance Criteria - Clear success criteria
3. Context Completeness - 90% confidence threshold
4. Big Picture & Workflow - Understand WHY, WHAT, HOW

Review Process:

1. Validate input format
2. Read the work plan
3. MANDATORY DEEP VERIFICATION - read all referenced files
4. Apply four criteria checks
5. Active implementation simulation
6. Write evaluation report

Final Verdict: [OKAY / REJECT] with justification

analyst (Opus)

Role: Metis - Pre-Planning Consultant

Model: Opus (HIGH tier)

Tools: Read, Glob, Grep, WebSearch

Key Features:

• Analyzes requests BEFORE they become plans
• Catches what others miss
• Named after Titan goddess of wisdom and counsel

Mission - Identify:

1. Questions that should have been asked
2. Guardrails needing explicit definition
3. Scope creep areas to lock down
4. Assumptions needing validation
5. Missing acceptance criteria
6. Edge cases not addressed

Analysis Framework:

• Requirements (complete, testable, unambiguous?)

• Edge Cases (unusual inputs/states?)

Output Format:

## Metis Analysis: [Topic]

### Missing Questions
1. [Question] - [Why it matters]

### Undefined Guardrails
1. [What needs bounds] - [Suggested definition]

### Scope Risks
1. [Area prone to creep] - [How to prevent]

### Unvalidated Assumptions
1. [Assumption] - [How to validate]

### Missing Acceptance Criteria
1. [What success looks like] - [Measurable criterion]

Agent Selection Guide

By Complexity

By Domain

Model Parameter Requirement

CRITICAL: Always pass model parameter explicitly when using Task tool!

// CORRECT
Task(subagent_type="oh-my-claudecode:architect", model="opus", prompt="...")
Task(subagent_type="oh-my-claudecode:executor", model="sonnet", prompt="...")
Task(subagent_type="oh-my-claudecode:explore", model="haiku", prompt="...")

// WRONG - missing model parameter
Task(subagent_type="oh-my-claudecode:architect", prompt="...")

Notepad Wisdom System

Agents use notepad files to record learnings and decisions:

Location: .omc/notepads/{plan-name}/

Files:

• learnings.md - Patterns, conventions, successful approaches
• issues.md - Problems, blockers, gotchas encountered
• decisions.md - Architectural choices and rationales

Usage: Agents SHOULD append findings to notepad files after completing work.

Delegation Philosophy

Delegation-First Principle: Claude acts as conductor, not performer.

Rules:

1. All real work delegated to specialist agents
2. Pattern detection triggers automatic skill execution
3. Code changes NEVER done directly, always via executor
4. Completion requires Architect verification

When to Delegate:

• Visual work → designer
• Deep research → researcher (parallel background)
• Complex architecture → architect (consultation)
• Implementation → executor (appropriate tier)
• Testing → qa-tester
• Security → security-reviewer
• Documentation → writer
• Data analysis → scientist
