Orchestrator - Multi-Phase Development

Build features through three validated phases. Each phase must pass before the next begins.

Phase 1: Research (GO/NO-GO)

Explore the codebase to assess feasibility.

1. Find all relevant files and patterns 2. Check dependencies and constraints 3. Identify existing patterns to follow 4. Score confidence (0-100 across 5 dimensions)

Confidence Scoring

• **Scope clarity** (0-20): Know exactly what files change?
• **Pattern familiarity** (0-20): Similar patterns exist in codebase?
• **Dependency awareness** (0-20): Know what depends on changed code?
• **Edge cases** (0-20): Can identify the edge cases?
• **Test strategy** (0-20): Know how to verify changes?

Score >= 70 → GO to planning Score < 70 → Gather more context, re-score. If < 70 after 2 rounds, ask user.

Phase 2: Plan (Approval Required)

Design the solution. Present for approval before any code changes.

Output

PLAN: [Feature Name]

Goal: [one sentence]

Files to modify:
1. path/file.ts - [what changes, why]

New files:
1. path/new-file.ts - [purpose]

Approach:
1. [step with rationale]

Risks:
- [potential issue and mitigation]

Test strategy:
- [how to verify]

Estimated scope: [S/M/L]

Wait for explicit "proceed" or "approved" before Phase 3.

Phase 3: Implement

Execute the plan step by step.

1. Make changes in the order specified in the plan 2. After each file: run relevant tests 3. After every 5 edits: pause for review checkpoint 4. After all changes: run full quality gates (lint, typecheck, test) 5. Present summary for final review

Rules

• Never skip phases. Research before planning, plan before implementing.
• Never proceed without approval between phases.
• If implementation reveals the plan was wrong, go back to Phase 2.
• Use project memory to recall patterns from previous feature builds.
• Capture learnings at the end: `[LEARN] Category: Rule`
