description: Delegate tasks or get a second opinion from OpenAI Codex CLI.

Infers mode (delegation vs validation) from prompt context. Detects

available models at runtime via the CLI. Use when cross-validating code,

plans, or architecture with Codex CLI, or offloading work to it.

- Do not use when already running inside Codex CLI or for tasks

- that do not benefit from cross-model input.

# Cross-Agent Task Runner — OpenAI Codex CLI

## Procedures

- **Step 1: Self-Call Detection**

- 1. Check for `codex` in process ancestry (no dedicated env var exists for Codex CLI).

- 2. If detected, stop and inform the user:

- "Cannot invoke Codex from within Codex. Use a different target CLI."

- **Step 2: Execute Shared Procedure**

+ **Step 1: Execute Shared Procedure**

1. Read `references/shared-procedure.md` for the core workflow

(mode inference, context gathering, prompt construction, result presentation).

2. Read `references/cli-codex.md` for Codex-specific flags, model selection

heuristics, and version compatibility matrix.

3. Follow the shared procedure using the Codex-specific details.
