description: This skill should be used when the user asks to "use Codex CLI", "codex exec", "get a Codex second opinion", or "run a Codex review" as a separate agent.

Codex CLI Delegation

Use Codex CLI as a parallel agent with its own context window. Prefer codex exec for headless runs and codex for the TUI.

When to Use

  • •Code review or spec/plan review
  • •Debugging second opinion
  • •Parallel implementation in an isolated worktree

Quickstart

bash
codex exec --sandbox read-only "Review src/auth against SPEC.md. Focus on security and tests."
codex exec --full-auto --cd ../worktrees/task-3 "Implement Task 3 from IMPLEMENTATION_PLAN.md."

Exec Inputs

  • •PROMPT string, or - to read stdin.
  • •--image, -i attaches one or more images to the first message.

Config and Model Overrides

  • •--model, -m overrides the configured model (e.g., gpt-5-codex).
  • •--profile, -p selects a profile from ~/.codex/config.toml.
  • •--config, -c key=value overrides config values (repeatable).
  • •--oss uses the local open source provider (requires Ollama).
  • •--cd, -C sets the working directory before execution.
  • •--skip-git-repo-check allows running outside a Git repo.

Safety Controls

  • •--sandbox, -s: read-only | workspace-write | danger-full-access.
  • •--ask-for-approval, -a: untrusted | on-failure | on-request | never.
  • •--full-auto: sets --ask-for-approval on-request and --sandbox workspace-write.
  • •--dangerously-bypass-approvals-and-sandbox, --yolo: no approvals or sandbox.
  • •--add-dir: grant extra write roots.
  • •--search: enable web search tool usage.

Output and Scripting

  • •--json / --experimental-json: newline-delimited JSON events.
  • •--output-last-message, -o <path>: write final assistant message to a file.
  • •--output-schema <path>: validate the final response against a JSON Schema.
  • •--color <always|never|auto>: control ANSI output.

Session Control

  • •codex resume [SESSION_ID] or codex resume --last [--all].
  • •codex exec resume [SESSION_ID] to continue non-interactive runs.
  • •codex fork [SESSION_ID] to branch a prior interactive session.

Notes

  • •Global flags apply to subcommands; place them after the subcommand (e.g., codex exec --oss ...).
  • •Codex runs with its own context window; include all necessary context in the prompt.
