/implement - Issue Implementation Skill

Orchestrates the complete workflow for implementing a GitHub issue, from branch creation to PR submission.

Language Requirement

IMPORTANT: All outputs (commits, PRs) MUST be written in English.

Workflow Overview

Issue Analysis → Branch Creation → Implementation → Commit → PR Creation

Steps

Step 1: Analyze Issue (MANDATORY)

gh issue view <issue-number>

Extract:

• •Issue title and description
• •Labels (to determine branch prefix)
• •Acceptance criteria
• •Files to modify

Step 2: Determine Branch Name

Based on issue labels:

Format: <prefix>/<issue-number>-<short-description>

Step 3: Create Feature Branch (MANDATORY)

# Verify not already on a feature branch for this issue
git branch --show-current

# If on develop or main, create new branch
git fetch origin
git checkout -b <branch-name> origin/develop

CRITICAL: This step cannot be skipped. If already on the correct feature branch, verify and continue.

Step 4: Implement Changes

• •Follow the issue's technical specifications
• •Adhere to project architecture (see .claude/instructions.md)
• •Add tests for new functionality
• •Update documentation as needed

Step 5: Commit Changes

Invoke /commit skill with:

• •Reference to issue number in commit message
• •Conventional commit format

Step 6: Create Pull Request

Invoke /pr skill with:

• •Base branch: develop
• •Reference to issue: Closes #<issue-number>

Step 7: Report Completion

Output:

• •Branch name created
• •Files modified
• •Commit hash
• •PR URL

Error Handling

Already on Feature Branch

If already on a feature branch:

1. •Verify it matches the issue being implemented
2. •If yes, continue from Step 4
3. •If no, ask user for clarification

Issue Not Found

If gh issue view fails:

1. •Report error to user
2. •Ask for correct issue number

Branch Already Exists

If branch already exists:

1. •Check if it's for the same issue
2. •Offer to switch to existing branch or create new one

Example Usage

User: "implement issue #96"

Claude executes /implement skill:

1. •Reads issue #96 details
2. •Determines label is "enhancement" → prefix "feature/"
3. •Creates branch feature/96-check-vulnerabilities-usecase
4. •Implements the changes per issue specification
5. •Runs /commit skill
6. •Runs /pr skill
7. •Reports: "Created PR #XX for issue #96"
