Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00055 | $0.00503 |
| Opus 5 | $0.00028 | $0.00251 |
| Sonnet 5 | $0.00011 | $0.00101 |
| Haiku 4.5 | $0.00006 | $0.00050 |
Grade A, and why
openai-docs-skill scanned grade A with 1 finding 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 yesterday.
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.

OpenAI Docs MCP Skill
Overview
Use the OpenAI developer documentation MCP server from the shell to search and fetch authoritative docs. Always do this for OpenAI platform work instead of relying on memory or non-official sources.
Core rules
- Always use this skill for OpenAI API/SDK/Apps/Codex questions or when precise, current docs are required.
- Query the MCP server via the CLI wrapper in
scripts/openai-docs-mcp.sh(do not rely on Codex MCP tools). - Use
searchorlistto find the best doc page, thenfetchthe page (or anchor) for exact text. - Surface the doc URL you used in your response so sources are clear.
Quick start
scripts/openai-docs-mcp.sh search "Responses API" 5
scripts/openai-docs-mcp.sh fetch https://platform.openai.com/docs/guides/migrate-to-responses
Workflow
- Discover:
searchwith a focused query. If unsure, uselistto browse. - Read:
fetchthe most relevant URL (optionally add an anchor). - Apply: summarize and/or quote relevant sections; include the URL.
Script reference
The CLI wrapper is at scripts/openai-docs-mcp.sh and uses curl + jq against https://developers.openai.com/mcp.
Subcommands:
init: initialize and inspect server capabilities.tools: list available tools on the MCP server.search <query> [limit] [cursor]: return JSON hits from the docs index.list [limit] [cursor]: browse docs index.fetch <url> [anchor]: return markdown for a doc page or section.endpoints: list OpenAPI endpoints.openapi <endpoint-url> [lang1,lang2] [code-only]: fetch OpenAPI schema or code samples.
Environment:
MCP_URL: override the default MCP endpoint.
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.

openai-docs-skill is a skill published in the GitHub repository GrayCodeAI/starling (2 stars, last pushed 2d ago), licensed MIT. It adds 55 tokens to every session and 503 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
