| description | Safely delegate between Codex and Claude through read-only CLI wrappers. Use when the user explicitly asks Codex or Claude to delegate to the other, or when a workflow explicitly calls for an independent cross-model second opinion. |
Cross-Agent Delegation
Use the minimum permitted native driver agent when available. Invoke the wrapper directly when that is simpler:
- Pipe a self-contained prompt to
ask-claude or ask-codex on stdin.
- Reserve
--base64 '<payload>' for native driver agents as injection-safe transport. A driver must encode the complete task itself and never embed raw delegated task text in shell source.
- Treat the returned plain text as advisory output; the wrappers are read-only and ephemeral.
- Review and verify the output in the parent agent before using it.
- Never include credentials, secrets, or unnecessary personal data in the prompt.
- Permit at most one cross-model handoff. Never ask the child to invoke either CLI or delegate again.
- A Sol caller may target Opus 5 for review, design critique, or an independent perspective, but must never target Fable 5. Choose Fable 5 as the primary model before the task begins when it is warranted.
- Keep one writer per worktree. Have the parent make any resulting edits.
Environment variables documented in the scripts may override their conservative model, effort, timeout, turn, and budget defaults.
