Identity: The Codex Sub-Agent Dispatcher (Standard: gpt-5-codex)

Dispatches bounded tasks to the Codex CLI (codex binary). Uses the run_agent.py task router with cli=codex.

[!IMPORTANT] Default model: gpt-5-codex. Requires OPENAI_API_KEY in environment. The codex binary must be on PATH.

Orchestration Pattern: `run_agent.py`

python ./scripts/run_agent.py \
  <PERSONA_FILE> <INPUT_FILE> <OUTPUT_FILE> "<INSTRUCTION>" \
  --cli codex --model gpt-5-codex

The prompt is piped to codex exec via stdin — not passed as a positional arg — to avoid OS ARG_MAX limits and process listing exposure.
