Local Codex

Delegate coding tasks to the local OpenAI Codex CLI agent using the authorized ChatGPT account's OAuth access.

When to Use

• User wants to generate, refactor, or review code via Codex
• User wants to run codex exec for non-interactive tasks
• User wants to use Codex's GPT-5.5 agent capabilities
• User mentions "codex", "run codex", "delegate to codex"

Authentication (ChatGPT OAuth)

CRITICAL: Use ChatGPT OAuth through the selected credential store. Do NOT set OPENAI_API_KEY or pass API keys for this workflow. Keep the authentication route separate from the account's allowance and extra Credit policy; OAuth does not guarantee that long work cannot consume extra Credit.

• Resolve the actual CODEX_HOME and store; the desktop app and CLI can share credentials.
• Before login, account switching or token recovery, read the OAuth guide and select its verified existing-owner branch or independent-grant recovery; retain explicit single-owner transfers and verify actual access, process adoption and business continuation separately.
• Before a native quota query, read refresh ownership; a nominally read-only query can refresh credentials.
• For quota-driven continuation on another authorized account, use the included-usage check before substantial execution; cached login or a new default file is not that check.
