description	Delegate tasks to OpenAI Codex CLI for review and get responses back. Use when user explicitly asks to "ask codex", "let codex review", or "pass to codex", or wants a second opinion from another AI on code or text, or wants code review via codex review command.

Ask Codex

Invoke OpenAI Codex CLI to review content and return results for discussion.

Modes

1. Code Review Mode (codex review)

For reviewing git changes:

# Review uncommitted changes
codex review --uncommitted

# Review against a branch
codex review --base main

# Review a specific commit
codex review --commit <sha>

# With custom instructions
codex review --uncommitted "Focus on security issues"

2. General Query Mode (codex exec)

For arbitrary prompts (read-only by default):

# Ask codex a question (read-only sandbox)
codex exec -s read-only "Review this code and explain potential issues: <content>"

# Pass content via stdin
echo "content to review" | codex exec -s read-only -

Workflow

1. Determine appropriate mode based on user request:

   • Git changes → use codex review
   • Arbitrary content → use codex exec -s read-only

2. Execute codex command and capture output

3. Present codex's response to user

4. If issues found, discuss with user and offer to help resolve

Examples

User: "Ask codex to review my uncommitted changes"

codex review --uncommitted

User: "Let codex review this function for bugs"

codex exec -s read-only "Review this function for potential bugs and suggest improvements:

<paste function code here>"

User: "Get codex's opinion on my PR against main"

codex review --base main

Important

• Default to read-only sandbox (-s read-only) unless user explicitly allows edits
• Always show codex's full response to user
• Discuss any issues or suggestions with user before taking action
