Runs an automated codex review loop — locally via the codex CLI (no PR needed), or on the current branch's PR via the GitHub App — fixing findings and re-reviewing until codex reports no issues. Use when the user wants codex to review code or a PR, says "ask codex to review", "codex review this locally", "loop codex on this", "get a clean codex pass", or types "/codex-review".
Chooses which model runs a delegated task (subagent, parallel fan-out, or Workflow stage) and how to invoke it. Use whenever spawning agents with the Agent tool, authoring or running a Workflow, delegating to a subagent, dispatching bulk/mechanical work, requesting a review, or otherwise deciding which model should do a piece of work. Trigger on "which model", "spin up agents", "fan out", "run a workflow", "delegate this", "have gpt/codex/fable/opus do X".
Generate high-converting App Store screenshots by analyzing your app's codebase, discovering core benefits, and creating ASO-optimized screenshot images using Nano Banana Pro.
Captures before+after screenshots of the visual changes in the current PR (desktop + mobile-web) using Playwright MCP, uploads them to GitHub as user-attachments, and posts/updates a single bot comment on the PR. Repo-agnostic — driven by an optional .screenshot-pr.json. Use when the user wants to attach screenshots to a PR, show visual changes for review, or runs "/screenshot-pr".
