## Description

Use when reproducing an existing Codex or Claude Code feature in Qwen Code or another agent CLI by choosing a reference agent, capturing HTTP request bodies, prompts, tool/function schemas, terminal output, and then implementing the matching behavior in the target repo.

# Agent Reproduce Feature

## Purpose

Use this skill to turn an observed feature from a reference agent into an implementation task for Qwen Code. The workflow treats the current session as the outer harness and runs a nested reference agent process as the program under test.

Default target repo: the current working directory. Use a user-specified path only when the user explicitly provides one.

## Reference Agent Selection

Start by selecting exactly one reference agent:

- `codex`: use nested Codex as the reference implementation.
- `claude-code`: use nested Claude Code as the reference implementation.

If the user did not choose one, ask once before capture. Then discover the local commands instead of assuming them:

```sh
command -v codex || true
command -v claude || command -v claude-code || true
```

Record the selected adapter in the run notes or scenario:

```json
{
  "reference_agent": "codex",
  "reference_interactive_command": "codex",
  "reference_headless_command": "codex exec",
  "target_agent": "qwen-code",
  "target_repo": "."
}
```
