Skills
agents
Build agent apps with the Agents API or Agents SDK. Use when adding tools, sessions, sandboxes, handoffs, guardrails, evals, or deployment.
devday-guide
Help with OpenAI DevDay attendance, onsite logistics, session schedules, personal plans, livestreams, recordings, and DevDay Exchanges. Use for DevDay-specific questions, not general OpenAI API or app development.
openai-api-troubleshooting
Use when an OpenAI API request fails and Codex needs to classify the likely cause, explain the next step, and route to the right follow-up. Covers common runtime failures such as blocked outbound network access, invalid credentials, exhausted API quota or credits, rate limits, and model, project, or organization access issues; delegate key provisioning to openai-platform-api-key and current documentation lookups to openai-docs.
openai-computer-use
Build or debug an application that uses OpenAI SDK computer or browser tools to operate a user-provided environment.
openai-platform-api-key
Use when Codex is asked to build, run, test, debug, or configure an OpenAI-backed or provider-unspecified AI app, UI, script, CLI, generator, or tool, especially requests phrased only as "using AI" or generators driven by forms/user input; also use for OPENAI_API_KEY or sk-proj setup. Treat this as the credential gate: inspect safely, ask reuse-vs-new before API work, and never expose plaintext.
setup
Use during OpenAI Developers post-install onboarding to set up API access, check for optional API credits, and verify a first Responses API request.
