live-docs-lookup

A skill that fetches current AI SDK/API documentation before answering any question about Anthropic, OpenAI, or Google APIs. Prevents stale training data from producing wrong model IDs, deprecated parameters, or missed APIs.

The problem it solves

AI coding assistants have a training cutoff. Documentation changes faster than models retrain:

• Model IDs get renamed or deprecated (gemini-1.5-flash → gemini-2.0-flash)
• Parameters get removed (budget_tokens deprecated on Claude Opus 4.6)
• New APIs replace old ones (OpenAI Responses API replaces Chat Completions for agents)
• Built-in tools go unnoticed (Anthropic's native web_search and web_fetch tools)

A 30-second doc fetch before answering catches all of these. See CREATION-LOG.md for the real-world failure that motivated this skill.

What it covers

Provider	What gets fetched
Anthropic	Models, tool use, streaming, prompt caching, batch API, extended thinking
OpenAI	Models, Responses API vs Chat Completions, function calling, streaming, batch
Google	Gemini models, Gemini API vs Vertex AI, function calling, structured output

Detection is automatic — the skill infers which provider is in scope from imports, environment variable names, and model name patterns in your code or question.

Install

Claude Code

cp -r live-docs-lookup ~/.claude/skills/

Other tools (Cursor, Codex, OpenCode)

Copy the live-docs-lookup/ directory into your tool's skills/plugins folder. Check your tool's documentation for the exact path.

How it triggers

The skill activates automatically when you ask about:

• Which model to use
• Tool use / function calling / structured output
• Streaming responses
• Prompt caching, batch processing, rate limits
• SDK setup, debugging, or planning for any AI API integration
• Anything that involves Anthropic, OpenAI, or Gemini

You can also force it at any time with the slash command:

/live-docs-lookup

Useful when you want a fresh doc check before starting a new feature, or when the skill didn't auto-trigger but you'd like it to.

Superpowers compatibility

If you use the obra/superpowers plugin system, you can install live-docs-lookup separately and it will work alongside it. It will automatically trigger before brainstorming, plan writing, or other SDK-related workflows — so plans are built on current docs.

Evals

The evals/ directory contains 9 test prompts (5 Anthropic, 2 OpenAI, 2 Google) used during development. Pass rate with skill: 100%. Without skill: 45%. See CREATION-LOG.md for details.
