A set of instructions for getting current, accurate guidance about OpenAI products, APIs, models, and software kits. It also covers model choices and prompt updates.

Use it to answer OpenAI development questions, look up documentation, choose or migrate models, improve prompts, and prepare API examples.

It helps avoid relying on outdated or guessed OpenAI information when building or changing code.

openai-docs — Skill for Claude Code by openai

About the project

OpenAI Developers for Claude Code is a Claude Code plugin bundle that connects OpenAI developer documentation and workflow guidance to Claude Code. It helps users build AI applications, agents, and ChatGPT Apps from Claude Code, including setup, troubleshooting, Agents SDK development, and app submission. The catalogue entries are the plugin's skills, plugin metadata, and documentation MCP integration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.01315
Opus 5.5	$0.00022	$0.00526
Sonnet 5.5	$0.00011	$0.00263

Security

Grade A, and why

openai-docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenAI Docs

Use the plugin-provided OpenAI Docs MCP server at https://developers.openai.com/mcp first for current OpenAI developer guidance. This skill also owns model selection, API model migration, and prompt-upgrade guidance.

API Key Setup

For requests that require a live OpenAI API call, use openai-platform-api-key first when available. Missing credentials block only the live call. They do not block requested source or configuration edits, documentation retrieval, or offline, mocked, static, fixture-based, or syntax validation.

Use this skill directly for docs-only questions, citations, model/API guidance, and examples that do not require a live API call.

For model migration or prompting-guidance requests, retrieve the relevant current guidance before any live-call credential check. Continue with requested source edits and offline validation when no API key is available; skip only validation that actually sends a live API request, and say that it was skipped.

First Action for Model Requests

Before inspecting a repository or checking API credentials, classify the model target:

Latest/current/newest/recommended/default/flagship/unspecified target: fetch https://developers.openai.com/api/docs/guides/latest-model.md through Docs MCP. Read its latestModelInfo block and follow the exact migrationGuide and promptingGuide URLs it provides. Do not infer those URLs or the current model.
Explicitly named target: preserve that model and fetch https://developers.openai.com/api/docs/guides/latest-model?model=<requested-model> through Docs MCP. For example, use ?model=gpt-5.6 or ?model=gpt-5.3-codex. Do not substitute the current model or guidance for a different model.

If a requested page is unavailable, contains only a title or no substantive body, retry the exact URL once through Docs MCP, then use a focused Docs MCP search for the same official guide. If the guide still cannot be retrieved, search only official OpenAI domains such as developers.openai.com and platform.openai.com. If that also fails, state what could not be verified and return bounded uncertainty. Never use bundled or remembered model facts as a fallback.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
