Codex-native parity wrapper. The full skill content — overview, critical
constraints, the three-phase workflow, output spec, exit codes, quality rubric,
examples, and troubleshooting — lives in the sibling base file ../SKILL.md.
Read it first.
Codex execution steps and guardrails for this skill are in prompt.md (same dir).
Temporary inboxes for agent signup QA — create disposable addresses, wait for verification email, extract OTP or magic links. Use when automating signup, login, or email verification without parsing HTML manually.
Spin up isolated sandboxes ("boxes") for coding agents, run them in parallel, queue background runs with -i, and push commits safely through the host relay. Use when the user wants to run Claude Code / Codex / OpenCode in a sandbox, start more boxes, attach to a running box, or otherwise operate the `agentbox` CLI on their laptop.
Use when building an HTTP val — a web endpoint, API route, webhook receiver, or any val that responds to HTTP requests. Covers the handler signature, Hono usage, the endpoint URL, CORS behavior, redirects, and Val Town-specific limitations.
Use when creating a new val and choosing which starter to fork. Covers the catalog of official starter templates, which project shape each one fits, and when forking an existing val is the better starting point.
Switch coding-agent accounts on a usage/rate limit, routed by host and agent.
Use Agent Mail from Codex for file leases, notifications, inboxes, and conflict prevention.
