Set up, use and troubleshoot hotpath, the feature-gated Rust profiler, by fetching the matching hotpath.rs docs page or agent procedure. Use when adding hotpath to a project, instrumenting Rust code with it, reading a hotpath report or hotpath.rs pull request comment, fixing a regression hotpath flagged, measuring Callgrind instruction counts, configuring hotpath-cloud CI, policies or budgets, or any question about hotpath. Not for general Rust performance work in projects that do not use or…
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
# Using hotpath [hotpath](https://hotpath.rs) is a feature-gated Rust profiler: every macro is a no-op and no dependency is compiled unless the `hotpath` cargo feature is enabled. This skill does not hold the API; it routes each task to the docs page or agent procedure that does. Fetch those before writing code or answering, and follow them instead of memory. ## Fetching the docs Every page of https://hotpath.rs is served as markdown with an `Accept: text/markdown` header, which costs far fewer tokens than HTML: ```bash curl -fsSL -H 'Accept: text/markdown' https://hotpath.rs/functions ``` - Pages under `/agent/` are step-by-step procedures, markdown only. When a task routes to one, fetch it and follow it. - If a fetch fails, stop and tell the user which URL failed; do not guess the API. - A `#fragment` is not sent to the server: fetch the whole page and find the heading. - Fetch only the pages the task needs, each once. Follow a link from a page only when you need the detail it points to. ## Routing Paths are relative to https://hotpath.rs. Fetch the pages listed for the task, plus the page of any other subsystem it touches. **Setup and profiling** | Task | Pages | …

How to install
mdr add pawurb/hotpath-rs/hotpath-rs@sha256:6dec3531102b6c2cThe line at the top of this page pins the label git:20261031.9c5ead0, 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.
