Look up Tampermonkey documentation — metadata keys (`@match`, `@grant`, `@run-at`, etc.), the GM_* / GM.* API, and configuration. Fetches the official docs page on demand to stay current.

When to use

The user asks about a specific metadata directive (@match vs @include, @require, @resource, @connect, @run-at, @inject-into, etc.).

Questions about a GM_* / GM.* function (GM_xmlhttpRequest, GM_setValue, GM_addStyle, GM.cookie, etc.).

Differences between Tampermonkey, Greasemonkey, and Violentmonkey behavior.

Method

Use mcp__jungle-shared__fetch-and-convert__fetch_markdown (or WebFetch as fallback) on:

https://www.tampermonkey.net/documentation.php?locale=en

Extract the section matching the user's question.

Quote the relevant directive signature + 1–2 sentences of explanation. Keep it concise.

If the question is about a GM. (promise-based) vs GM_ (sync) variant, mention both and which one Tampermonkey recommends.

Common gotchas to flag proactively

@match is stricter and faster than @include; prefer it.

@grant none runs the script in the page context (can touch window, no GM_*). Any other grant runs in a sandbox with unsafeWindow for page access.

@run-at document-start fires before the DOM is ready — use it for header injection, not DOM mutation.

@require URLs are fetched once at install time and cached; updating the remote file does not re-fetch unless the user reinstalls.

@connect is required for cross-origin GM_xmlhttpRequest.
