TDD Skill Improvement Assistant

This skill assists in improving the tdd-development skill by providing structured guidance for modifications.

Trigger Conditions

• "tdd スキルを改善", "tdd-development を修正"
• "Phase N を改善" (any phase reference)
• "tdd workflow の調整"
• "探索レベルの調整", "retry 制御の変更", "learning 記録の改善"

Workflow

Step 1: Understand the Request

Clarify what the user wants to improve. If the request is ambiguous, use AskUserQuestion with options:

Japanese message examples:

• "どのような改善を行いたいですか？"
• "対象のフェーズを選択してください"

Step 2: Reference Structure

Read references/structure.md to understand the tdd-development skill architecture and identify target files.

Step 3: Analyze Target (if needed)

If the improvement requires understanding the current implementation:

1. Read the target phase file(s) using Serena tools
2. Identify the specific section(s) to modify

Step 4: Present Plan and Get Approval

Present the improvement plan to the user:

1. 変更対象ファイル: List files to be modified
2. 変更内容の概要: Brief description of changes
3. 選択肢（ある場合）: If there are options, present them using AskUserQuestion

Japanese message for approval:

• "上記の変更を実施してよろしいですか？"
• Options: "はい、実施してください", "修正が必要です"

Step 5: Execute Changes

After approval, use Serena tools to make the modifications:

• mcp__plugin_serena_serena__replace_content for targeted changes (preferred)
• Edit tool for simple text replacements

Step 6: Report Changes

Present a summary of changes made:

Japanese report format:

## 変更完了

### 変更されたファイル
- `<file-path>`: <brief description>

### 変更内容
<summary of what was changed>

### 確認事項
<any follow-up actions or recommendations>

Common Improvement Patterns

Exploration Level Adjustment (Phase 1)

• Target: phases/1-exploration.md
• Options: quick, focused, full, custom
• Consider: profile freshness thresholds, scope decision logic

Retry Control (Phase 6/8)

• Target: phases/6-quality-checks.md, phases/8-code-review.md, SKILL.md
• Parameters: max retries, cycle limits, reset conditions

Learning Record Improvements

• Target: phases/9-final-report.md, various phases
• Consider: what to record, where to store, when to apply

Sub-agent Prompts

• Target: Any phase file that launches sub-agents
• Consider: return directives, max_turns, context passing

State Management

• Target: SKILL.md, individual phase files
• Consider: STATE.json fields, phase transitions
