Fetch HexDocs for Elixir libraries with HTML-to-markdown conversion.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HexDocs Fetcher Efficiently fetch Elixir library documentation from hexdocs.pm using Claude Code's native `WebFetch` tool. ## Usage When researching libraries, use `WebFetch`: ``` # Fetch library overview WebFetch( url: "https://hexdocs.pm/oban", prompt: "Extract the main documentation, including module overview, installation instructions, and key functions. Format as clean markdown." ) # Fetch specific module docs WebFetch( url: "https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html", prompt: "Extract the module documentation including all public functions, their specs, and examples." ) # Fetch getting started guide WebFetch( url: "https://hexdocs.pm/ecto/getting-started.html", prompt: "Extract the complete getting started guide content." ) ``` ## Token Efficiency WebFetch automatically converts HTML to markdown and extracts relevant content: | Source | Raw HTML | With WebFetch | Benefit | |--------|----------|---------------|---------| | HexDocs page | ~80k tokens | ~15k tokens | **80% reduction** | | Phoenix docs | ~120k tokens | ~25k tokens | **79% reduction** | | README | ~20k tokens | ~8k tokens | **60% reduction** | …

How to install
mdr add oliver-kriska/claude-elixir-phoenix/hexdocs-fetcher@sha256:30b0dafc451750b5The line at the top of this page pins the label git:20260721.df395b3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
