fetch skillA
fetch is agent-read markdown (skill) from grainulation/grainulator: Size-efficient URL fetch with semantic extraction. Use for ad-hoc web research when you want content without the raw HTML overhead..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# /fetch -- Ad-hoc URL fetch with smart extraction Pulls a URL's main content (title, description, body paragraphs) without the HTML boilerplate. Delegates to Grainulator’s `memory_smart_fetch` MCP tool, which strips scripts/styles/nav/footer and targets `<main>` or `<article>` regions. Typical reduction: 80-99% vs raw HTML. ## Arguments $ARGUMENTS Expected: `/fetch <url> [--mode auto|concise|full|meta-only] [--no-cache] [--privacy]` - **`--mode auto`** (default): tries concise extraction; retries full only when extraction failed and was truncated - **`--mode concise`**: caps body at ~2KB - **`--mode full`**: returns fuller extraction within fetch/body limits; check truncation - **`--mode meta-only`**: only title + description (smallest) - **`--no-cache`**: skip local cache read, force network fetch - **`--privacy`**: don't write to cache (use for sensitive URLs) ## When to use - **Quick reference**: "what does this page say" — `/fetch <url>` beats opening a browser - **Before witnessing**: peek at content before committing to `/witness` (which creates a claim) - **Third-party pages**: docs sites, blog posts, research articles …

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
