Find guidance on Codex settings, pricing, and OpenAI products and APIs using current official documentation. Get cited answers for setup, troubleshooting, model comparisons, migration planning, and prompt changes, with uncertainty stated when sources are inconclusive.
Use for Codex models/pricing, scheduled tasks, skills, settings, setup, troubleshooting, customization, automations, and self-knowledge—including 'you,' 'your,' 'this app,' or 'this coding agent' when they refer to Codex—and for OpenAI APIs/products and ChatGPT Work. Also use for model choice/migration, prompting, SDKs, Responses, Realtime, agents, evals, and Chat/Work/Codex comparisons. Do not use for generic app/software tasks that merely mention Codex.
Researches official documentation to provide cited guidance on Codex settings, setup, pricing, skills, and automation, as well as OpenAI APIs and products. It also supports model comparisons and selection, migration planning, prompt adjustments, and research into implementations using SDKs. It opens the relevant official pages and checks their content instead of relying only on search result summaries.
Use it to check Codex features and settings, learn how to use an API, or investigate the cause of an error. It also helps when comparing model cost, speed, and quality, or checking differences between products such as ChatGPT Work and Codex against official information.
Requires searching and retrieving official documentation. Sources are restricted to developers.openai.com, platform.openai.com, and learn.chatgpt.com. Pricing, usage conditions, and behavior that official sources cannot establish are treated as uncertain. For implementing or running an app that uses an API, the workflow includes checking the API key first.
This overview was written by AI (OpenAI Codex) from the public SKILL.md. Check the original below for the exact behavior.
AI rated this skill on four points using only the contents of its SKILL.md. Stars and popularity are not taken into account.
The total counts each point as A = 25, B = 15, C = 5. Rated by AI (OpenAI Codex) as of Oct 20, 2026. Treat it as a guide and read the original before installing.
Review the instructions the agent will receive before you install.
Provide current, cited OpenAI product, API, model, and Codex guidance. Read zero or one primary reference.
First substantive action: Search the user's exact requested official OpenAI documentation topic and any explicitly named model using a concise, topic-specific query of 2-6 essential terms. When an already-available direct official documentation search and page-retrieval capability is present, use it first: search, then fetch or open the matching official page before general web search. Otherwise, immediately use official-domain web search, then actually open or fetch the relevant official page. Complete this source order before reading a reference, inspecting local or repository files, running a Codex manual or model resolver, drafting a plan, or answering from memory. Use the actual fetched page, not a search snippet or an unopened link. If one official search or page does not establish the answer, search another appropriate official domain and actually open or fetch the result. Preserve the exact requested model; never substitute a newer model.
Only exception: An explicitly requested, genuinely broad, cross-topic Codex setup, orientation, or system-map synthesis may use the manual first when shell execution and an allowed temporary cache are available. A specific Codex feature, setting, command, error, model, or requested citation remains docs-first. Mixed Chat/Work/Codex comparisons are official documentation questions, not manual-first Codex requests.
For generic software tasks, answer the software task directly. OpenAI implementation, debugging, SDK, API, prompting, agent, and eval requests are not generic.
For a straightforward factual or citation-only request, follow the source order and do not read a route reference. This includes straightforward API facts, ChatGPT Work or mixed Chat/Work/Codex comparisons, model tiers, aliases, Pro mode, reasoning settings, factual migration baselines, and narrow Codex facts. Prioritize learn.chatgpt.com for ChatGPT Work.
Use the first matching route, and read its reference only when the requested task needs that specialized workflow:
Read at most one primary reference. Do not open every route, bundled model guide, or helper script. Read a supporting reference or run a helper only when the chosen workflow demonstrably needs it.
developers.openai.com, platform.openai.com, and learn.chatgpt.com. Cite the page that supports the claim. State uncertainty when official sources do not establish pricing, availability, account access, limits, or behavior.references/latest-model.md only as a disclosed fallback after current official model guidance does not answer the question. Read references/upgrading-to-gpt-6-astra.md only for an actual, requested GPT-6 migration; read references/prompting-guide.md only for requested prompting work.openai-platform-api-key first when available. Documentation, conceptual examples, model selection, and read-only guidance do not require an API key.No reviews yet. Tell others what you thought.
