Code Implementation

Invoke the implementer agent to write code that makes tests pass.

Implementation

Invoke the implementer agent with the user's feature description.

ARGUMENTS: {{ARGUMENTS}}

Use the Task tool to invoke the implementer agent with subagent_type="implementer" and provide the feature description from ARGUMENTS.

What This Does

You describe a feature. The implementer agent will:

1. Write code to make failing tests pass (TDD approach)
2. Follow existing code patterns and conventions
3. Implement clean, maintainable code
4. Ensure all tests pass after implementation

Time: 5-10 minutes (vs 20-30 min full pipeline)

Usage

/implement rate limiting with Redis backend

/implement JWT authentication with token refresh

/implement blog post CRUD API endpoints

Output

The implementer provides:

• Working Code: Implementation that makes tests pass
• Pattern Compliance: Follows existing codebase conventions
• Clean Implementation: Maintainable, readable code
• Test Coverage: All tests passing

When to Use

Use /implement when you need:

• Code generation after tests are written
• Implementation without full pipeline overhead
• Quick feature implementation
• Following TDD workflow (tests already exist)

Prerequisites

For best results:

1. Tests should already exist (use /test-feature or write manually)
2. Have a plan (use /plan or know the approach)

If no tests exist, the implementer will still work but may not follow TDD.

Next Steps

After implementation, you can:

1. Review code - Use /review for quality check
2. Security scan - Use /security-scan for vulnerabilities
3. Update docs - Use /update-docs for documentation
4. Full pipeline - Use /auto-implement <feature> for complete workflow

Comparison

Command	Time	What It Does
/research	2-5 min	Research only
/plan	3-5 min	Research + planning
/test-feature	2-5 min	TDD test generation
/implement	5-10 min	Code implementation (this command)
/review	2-3 min	Code quality review
/auto-implement	20-30 min	Full pipeline (research → plan → test → implement → review → security → docs)

Technical Details

This command invokes the implementer agent with:

• Model: Sonnet (balanced speed/quality)
• Tools: Read, Write, Edit, Grep, Glob, Bash
• Permissions: Can write code and run tests
