Claude to Codex

Converts any Claude skill into a Codex-compatible skill. Searches the Claude skill marketplace by name, fetches the SKILL.md, rewrites Claude-specific tool references, generates agents/openai.yaml, and writes output to .codex/skills/. Use when asked to convert, port, or transform a Claude skill for use in Codex. Invoke with $claude-to-codex <skill-name>.

Transform any Claude skill into a Codex-compatible skill in one command.

---

## Usage

```
$claude-to-codex <skill-name> [flags]
```

### Flags

| Flag | Effect |
|---|---|
| `--global` | Install to `~/.codex/skills/` instead of `.codex/skills/` |
| `--dry-run` | Print the transformed SKILL.md without writing any files |
| `--no-yaml` | Skip generating `agents/openai.yaml` |
| `--overwrite` | Replace an existing skill without prompting |
| `--multi-agent` | Use explorer + worker sub-agents for Steps 3–6 (see below) |
| `--test` | After writing files, run skill-creator validation on the output |

### Examples

```bash
$claude-to-codex git-commit
$claude-to-codex docx --global
$claude-to-codex "write commit" --dry-run
$claude-to-codex docx --multi-agent
$claude-to-codex docx --test              # convert + validate output
$claude-to-codex docx --dry-run --test    # preview + validate without writing
```

---

## Execution mode

**Default (single agent):** You run all 8 steps yourself, in order.
Fast, simple, best for most single conversions.

**`--multi-agent`:** Steps 3–4 go to an explorer agent, Steps 5–6 to a
worker agent. Use for large skills (500+ lines) or bulk conversions.

**`--test`:** Adds Step 7b validation after writing. Inline by default.

**`--test --multi-agent`:** Step 7b spawns an independent tester sub-agent
that reads the output cold — no context of how it was written. Strictest
validation mode.
