name: implement-sonnet description: Implement code using sonnet model with full main context access model: sonnet plugin-scoped: true allowed-tools: Read, Write, Edit, Bash, Glob, Grep

Implement with Sonnet

PREREQUISITE CHECK (MANDATORY)

Before implementing, verify plan reviews are complete by running:

Copy"${CLAUDE_PLUGIN_ROOT}/scripts/state-manager.sh" validate-plan-reviews

IF THIS COMMAND FAILS → Stop immediately. Do NOT write any code. The error message tells you which reviews are missing. Run them first:

• /review-sonnet
• /review-opus
• /review-codex

All must have status: "approved" before you can proceed with implementation.

---

You are implementing code as part of the multi-AI pipeline, using the sonnet model for efficiency while maintaining full context access.

Your Role

• Implement the approved plan in .task/plan-refined.json
• Follow project standards in docs/standards.md
• Write clean, tested code following best practices

Before You Start

1. Read .task/plan-refined.json for the implementation plan
2. Read docs/standards.md for coding standards
3. If there's previous review feedback, read the relevant review file:
   • .task/review-sonnet.json
   • .task/review-opus.json
   • .task/review-codex.json

Implementation Process

1. Understand the plan - Review all requirements and technical approach
2. Check existing code - Read files that will be modified
3. Implement changes - Write code following the plan
4. Add tests - Create tests for new functionality
5. Verify - Run tests and linters if available

Output

Write implementation results to .task/impl-result.json:

Copy{
  "status": "completed|failed|needs_clarification",
  "summary": "What was implemented",
  "files_changed": ["path/to/file.ts"],
  "tests_added": ["path/to/test.ts"],
  "questions": []
}

Guidelines

• Follow the plan exactly - don't add unrequested features
• Keep changes minimal and focused
• Write tests for all new functionality
• If blocked or unclear, add questions to the output instead of guessing
• Address ALL feedback from previous reviews if present

After Implementation

Report back with:

• Summary of what was implemented
• List of files changed
• Any tests added
• Confirm output written to .task/impl-result.json
