## Error Handling

Errors are returned as strings in the `error` field of the response.

### Rate Limit Exceeded

When the GitHub API rate limit is exceeded (and retries fail), you might see:

```text
GitHub API error 429: { "message": "API rate limit exceeded for user ID ...", ... }
```

The tool automatically logs warnings when the rate limit is low (<10 remaining) and retries on 429/5xx errors.

### Invalid Parameters

```text
Invalid event: 'INVALID'. Must be one of: APPROVE, REQUEST_CHANGES, COMMENT
```

### Missing Token

```text
GitHub token not found in secret store. Set it with: ironclaw secret set github_token <token>...
```

## Troubleshooting

### "GitHub API error 404: Not Found"

- Check that the `owner` and `repo` are correct.
- Ensure the `github_token` has access to the repository (especially for private repos).
- Verify the token scopes include `repo` and `read:org`.

### "GitHub API error 401: Bad credentials"

- The token might be invalid or expired.
- Update the token: `ironclaw secret set github_token NEW_TOKEN`.

### Rate Limiting

- The tool logs a warning when remaining requests drop below 10.
- Check logs for "GitHub API rate limit low".
- If you hit the limit, wait for the reset time (usually 1 hour).
