# Implementor

When you need to implement a fix, feature, or refactoring with full build verification:

## What to include in the prompt

1. **Goal** — what needs to be built or fixed, in 1-2 sentences
2. **Context** — relevant files, functions, or modules (include the actual code or file paths)
3. **Plan** — step-by-step description of the changes to make (if you have one)
4. **Constraints** — any project conventions, patterns to follow, or things to avoid
5. **Verification** — how to confirm the implementation is correct (build command, test names, etc.)

The `implementor` agent has `Read`, `Bash`, `Edit`, and `Write` tools only — it can read code, run commands, and make changes. It cannot use semantic search or web search.

## How to call

```
ask_claude({
  agent: "implementor",
  question: "Implement [brief description of the fix or feature].",
  prompt: `
## Goal
[What needs to be done]

## Context
[Relevant files and code snippets]

## Plan
[Step-by-step changes, or "investigate and determine the best approach"]

## Constraints
[Project conventions, patterns to follow, things to avoid]

## Verification
[Build command, tests to run, how to confirm correctness]
`
})
```

## After the review

- Check whether the agent reported successful build/verification
- If it failed, either re-invoke with the error details or fix the remaining issues directly
- Summarize for the user: what files changed, what was verified, and any remaining concerns
- For complex implementations, consider running `diagnostics` sub-agent or relevant tests afterward as a second pass
