Methodology System Skill

Language: English | 繁體中文

Version: 1.0.0 Last Updated: 2026-01-12

Overview

The Methodology System provides a unified framework for managing development methodologies in projects that adopt Universal Development Standards. It supports:

• TDD - Test-Driven Development (Red → Green → Refactor)
• BDD - Behavior-Driven Development (Discovery → Formulation → Automation)
• SDD - Spec-Driven Development (Proposal → Review → Implementation → Verification → Archive)
• ATDD - Acceptance Test-Driven Development (Workshop → Distillation → Development → Demo)
• Custom - User-defined methodologies

Features

1. Phase-Aware Guidance

AI automatically tracks the current phase and provides context-appropriate guidance:

Copy┌─────────────────────────────────────────────┐
│ 📋 Current Methodology: TDD                  │
│ 📍 Current Phase: 🔴 RED (1-5 min)           │
│                                             │
│ Checklist:                                  │
│   ✅ Test describes behavior                │
│   ✅ Test name is clear                     │
│   ⬜ Test follows AAA pattern               │
│   ⬜ Test fails when run                    │
│                                             │
│ Next: Write the test following AAA pattern  │
└─────────────────────────────────────────────┘

2. Checkpoint Reminders

Automatic reminders based on methodology triggers:

• Phase Transition: Suggest commit when phase completes
• Accumulation Warning: Warn when changes exceed threshold
• Skip Warning: Alert after consecutive skipped check-ins

3. Methodology Switching

Switch between methodologies as project needs change:

Copy/methodology switch bdd

4. Custom Methodology Support

Define team-specific workflows in .standards/methodologies/:

Copyid: my-team-workflow
name: My Team Workflow
phases:
  - id: plan
    name: Planning
    checklist:
      - id: requirements-clear
        text: Requirements understood
        required: true

Commands

Configuration

Methodology configuration is stored in .standards/manifest.json:

Copy{
  "methodology": {
    "active": "tdd",
    "available": ["tdd", "bdd", "sdd", "atdd"],
    "config": {
      "tdd": {
        "checkpointsEnabled": true,
        "reminderIntensity": "suggest",
        "skipLimit": 3
      }
    }
  }
}

Configuration Options

AI Behavior

Detection

1. Check .standards/manifest.json for methodology.active
2. Load methodology definition from:
   • Built-in: methodologies/{id}.methodology.yaml
   • Custom: .standards/methodologies/{id}.methodology.yaml

Phase Tracking

• Track current phase based on trigger conditions
• Update phase when exit conditions are met
• Provide phase-specific guidance and checklist

Context Keywords

AI will automatically activate methodology context when these keywords are detected:

Integration with Other Standards

Check-in Standards

When a phase completes, the methodology system integrates with checkin-standards.md:

CopyPhase GREEN completed.

Code Review

Additional review checks are added based on active methodology:

• TDD: Tests follow naming conventions, single behavior per test
• BDD: Declarative style, reusable steps
• SDD: Change matches spec, no scope creep
• ATDD: All acceptance criteria have tests
