Implementation Review (Code Phase)

You are conducting an implementation review for decision ID:

$1

.

This review happens after implementation is complete (implementationStatus: IN_REVIEW).

Your Task

Review the implementation code to verify it matches the decision requirements.

1. Read the Decision Document

First, read

CDD/**/*$1*.cdd.md

to understand:

• Goal: What was supposed to be achieved
• Selection: What approach was chosen and why
• Rejections: What alternatives were explicitly rejected (should NOT be in the implementation)
• Review Criteria: Any specific review points mentioned in the document

2. Check for Review Criteria Section

If the cdd.md contains a

## Review Criteria

section:

• Read any referenced documents (e.g., "参照: docs/SECURITY.md")
• Apply the criteria specified in that section
• Document your findings in the review report

3. Locate Implementation

Two methods to find implementation files:

Method 1: Git commit search (Primary)

Use the Bash tool to search for commits related to this decision:

git log --all --grep="CDD: $1" --name-only --pretty=format:"%H %s"

This will show:

• Commit hashes and messages containing

  CDD: $1

• Files changed in those commits

Extract the file list from the commits for review.

Method 2: Code marker search (Fallback for older implementations)

If no commits are found, search for

@cdd #$1

markers (deprecated but may exist in older code):

grep -r "@cdd #$1" --include="*.ts" --include="*.js" --include="*.tsx" --include="*.jsx"

Prefer Method 1 - Git commits are the source of truth for recent implementations.

4. Conduct the Review

Check the following:

Decision Alignment

• All items in the Selection section are implemented correctly
• None of the Rejections section items are present in the implementation
• Implementation follows the constraints and guidelines in the Context section

Code Quality

• Code follows project conventions and style
• Appropriate error handling
• Adequate test coverage

Architecture & Security (if applicable)

• Follows architectural principles
• Security best practices applied
• No security vulnerabilities introduced

5. Generate Review File

Create a review file at:

CDD/.logs/review/$1-{{YYYYMMDD}}-{{sequence}}.md

Use this structure:

---
reviewId: $1-{{YYYYMMDD}}-{{sequence}}
decisionId: $1
decisionFile: {{path to cdd.md}}
reviewDate: '{{YYYY-MM-DDTHH:mm}}'
reviewer: AI
status: [APPROVED|REJECTED|NEEDS_REVISION]
---

## Summary

[Brief overview of the review - 2-3 sentences describing what was reviewed and the outcome]

## Implementation Check

### Decision Alignment

- [x] Selection section items are implemented
  - [Detail what was checked and found]
- [x] Rejections section items are NOT implemented
  - [Detail what was verified]
- [x] Context constraints are followed
  - [Detail compliance]

### Code Quality

- [x] Code follows project conventions
- [x] Error handling is appropriate
- [x] Tests are adequate

## Review Criteria Check

[If Review Criteria section exists in cdd.md, document findings here]

### [Criterion 1]
- Finding: ...
- Status: ✅ Pass / ❌ Fail / ⚠️ Needs attention

### [Criterion 2]
- Finding: ...
- Status: ✅ Pass / ❌ Fail / ⚠️ Needs attention

## Issues Found

[List any issues discovered - omit this section if no issues]

1. **[Issue Title]**
   - Location: file:line
   - Description: ...
   - Severity: Critical / High / Medium / Low
   - Recommendation: ...

## Conclusion

**Status:** [APPROVED|REJECTED|NEEDS_REVISION]

[Final verdict with brief justification]

### Next Steps

[Only if REJECTED or NEEDS_REVISION]
- Action 1
- Action 2

6. Update cdd.md (IMPORTANT)

After creating the review file, you MUST update the cdd.md file to add the review to its

reviewHistory

in the YAML frontmatter:

reviewHistory:
  - date: '{{YYYY-MM-DDTHH:mm}}'
    file: 'CDD/.logs/review/$1-{{YYYYMMDD}}-{{sequence}}.md'
    status: '[APPROVED|REJECTED|NEEDS_REVISION]'

Append this to the existing

reviewHistory

array if it exists, or create the field if it doesn't.

7. Present Results and Update Status

Show the user:

1. Review status (APPROVED/REJECTED/NEEDS_REVISION)
2. Key findings (if any issues)
3. Path to the review file
4. Confirmation that cdd.md was updated

If Review Status is APPROVED

Use AskUserQuestion tool to confirm:

• Question: "レビューがAPPROVEDになりました。implementationStatusをDONEに変更しますか？"
• Options: "はい" / "いいえ"

If "はい":

• Update the cdd.md file to change

  implementationStatus: DONE

• Use the Edit tool to update the frontmatter
• Show confirmation: "✓ Updated implementationStatus to DONE"

If "いいえ":

• Keep current implementationStatus unchanged
• Show confirmation: "implementationStatus kept as-is"

Important:

• Only use AskUserQuestion if the review status is

  APPROVED

• Do not ask for

  REJECTED

  or

  NEEDS_REVISION

  reviews

File Naming Convention

• Format:

  $1-{{YYYYMMDD}}-{{sequence}}.md

• Example:

  PHASE1.1-A-20260120-1.md

• Sequence number differentiates multiple reviews on the same day
• Check existing files to determine the next sequence number

Important Notes

• Be thorough but concise
• Focus on objective findings, not opinions
• If uncertain about something, investigate further before making a judgment
• Use checkboxes ([x] / [ ]) to make findings scannable
• Always reference specific file locations when mentioning issues
• The review should be constructive and actionable
