Live Docs Lookup

Why this skill exists

AI platforms change constantly: model IDs get renamed, parameters get deprecated, new features launch behind flags, entire APIs get replaced. Your training data has a cutoff — this skill fetches live docs before you advise on any AI SDK integration, catching the gap between what you remember and what's actually current.

A 30-second doc check prevents hours of wasted implementation effort.

Step 1: Detect which provider is in scope

Check imports, environment variables, model names, or the user's stated intent:

If multiple providers are in scope (e.g. a multi-provider app), fetch docs for each. If unclear, ask the user which SDK they're targeting before fetching.

Step 2: Fetch the relevant live docs

Use your web fetching tool (WebFetch, web_search, browse, or equivalent).

Always fetch the models page first — model IDs are the most common source of outdated guidance, and the user will copy-paste whatever you put in example code. Stale IDs produce confusing "model not found" errors.

If a URL fails or returns a redirect/404, don't stop — search for it instead. Restrict the search to the provider's official docs domain to avoid landing on blog posts or unofficial mirrors:

• Anthropic: site:platform.claude.com/docs
• OpenAI: site:developers.openai.com
• Google: site:ai.google.dev

Example queries: site:platform.claude.com/docs adaptive thinking or site:developers.openai.com responses API. Doc URLs move; the information is always findable on the canonical domain.

Fetch only what's relevant to the task. Three parallel fetches is ideal; don't flood context with docs the user doesn't need.

Step 3: Surface a brief summary

Present only what's relevant and potentially surprising given your training data. Aim for 5–10 bullet points, not a wall of text:

Current recommended models: [list the relevant current model IDs]

Key API details for [features in scope]: [params, headers, syntax that matters]

Watch out for: [deprecations, gotchas, recently changed behavior — omit if nothing notable]

If the docs confirm what you'd expect: "Docs confirm current expected behavior. Recommended model: claude-opus-4-6."

Step 4: Proceed with the original task

Carry the grounded context forward into all code, tests, plans, and reviews. The correct model IDs, parameter names, and feature knowledge should flow through naturally — don't repeat the summary, just use it.

If invoked before a superpowers skill: proceed to invoke that skill next. The live context is now loaded — carry it forward.

Common things to verify

Things that change often and are most likely to be wrong in training data:

Anthropic

• budget_tokens / thinking params — syntax and supported models have changed across versions; verify current API shape in docs
• output_format / output config params — naming has changed; verify current parameter structure from docs
• Model ID suffixes — never construct date-suffixed IDs from memory; copy exact aliases from the models page
• Beta headers (Files API, Compaction, etc.) — required headers and values change; verify current values from docs before using
• Docs base URL — has moved before; if a URL fails, re-find on platform.claude.com/docs

OpenAI

• API surface choice — verify which API the docs currently recommend for the user's use case
• Model IDs — always copy from the live models page
• SDK migration details — confirm version-specific breaking changes before suggesting code
• Output formatting features — verify the current recommended pattern from the docs

Google

• Gemini API vs Vertex AI — clarify which surface the user is targeting, then fetch the matching docs
• SDK choice and imports — verify the current recommended SDK/import path from live docs
• Model IDs — always verify from the live models page

Superpowers integration

Live doc lookup is most valuable before any planning, implementation, testing, debugging, or review of AI SDK work — catching stale assumptions before they get baked into a plan or test suite.
