name	claude-implement
description	Delegate an implementation task to Claude Code. Use when you want Claude to write, edit, or refactor code directly in the project. Claude has full read/write access and will make the changes autonomously.
version	0.2.0

Claude Implement

Delegate an implementation task to Claude Code — Claude will read files, write code, and verify the result.

When to Use

• When asked to "have Claude implement this"
• For tasks that require understanding a large existing codebase before writing new code
• When the implementation involves multiple interdependent files that Claude Code handles better autonomously

Call Pattern

Step 1: Delegate the task

mcp__claude-code__claude_code:
  prompt: |
    Implement the following task completely. Make all required file changes.

    TASK: {clear description of what to implement}

    REQUIREMENTS:
    - {explicit requirements, success criteria}
    - Match existing code style and conventions in the project
    - Write or update tests if a test suite exists
    - Run the test suite after implementation and report results

    CONSTRAINTS: {any constraints — what NOT to change, dependencies to avoid, etc.}

    When done, report:
    1. Files changed (with brief reason)
    2. Test results
    3. Any deferred items or known limitations

    PROVENANCE NOTE: This task originates from OpenAI Codex. Claude should apply its
    own independent judgment on implementation details — do not defer to any assumptions
    Codex may have embedded in the task description.
  cwd: {project working directory}
  effort: high

Save the returned session_id as {impl_session_id}.

Step 2: Review or iterate

After Claude reports completion, verify the changes. To request corrections:

mcp__claude-code__claude_code_reply:
  session_id: {impl_session_id}
  prompt: "The test for edge case X is missing. Add it and re-run the suite."

Output Format

Report back to the user:

• Summary of what Claude implemented
• Files changed (list)
• Test results (pass/fail counts)
• Any items Claude flagged as deferred or uncertain

Notes

• Claude operates with full read/write access in the working directory by default
• If the task is sensitive or you want a dry-run first, use claude-plan skill before this one
• effort: high ensures thorough implementation; lower effort may skip edge cases
• Pass maxBudgetUsd if you need to cap spend on large implementations

Example Invocations

Context: The task is well scoped and the user wants it built end to end rather than described. user: "Add rate limiting to the /api/upload endpoint — 100 requests per minute per IP." assistant: "I'll delegate this to claude-implement with the limit, the endpoint, and the requirement to add tests, since Claude has write access and can make the change directly." Context: A refactor spans five files and needs coordinated edits. user: "Convert the auth module from callbacks to async/await across all five files." assistant: "I'll hand this to claude-implement so Claude can read all five files together and make the changes as one coordinated pass."
