Detects skills fetching external URLs to use as runtime instructions
WebFetch to load `https://raw.githubusercontent.com + guidelinesPin the downloaded resource to a specific version or commit hash, and verify its integrity with a checksum (SHA-256). Avoid fetching scripts or binaries from arbitrary URLs at runtime.
Likely FP if the download URL points to a well-known CDN or package registry (e.g., npmjs.com, pypi.org) and is pinned to a specific version.
Detects fetching remote documentation or code to load as agent context
WebFetch to load + https://modelcontextprotocol.io/llms-full.txtPin the SDK or script to a specific version and verify its checksum after download. Prefer installing SDKs via a package manager instead of fetching remote scripts directly.
Likely FP if the match is documentation showing how to install an official SDK (e.g., Google Cloud SDK, AWS CLI) from its canonical URL.
Detects URLs fetched at runtime that control or influence agent behavior without pinning
Fetch to load: `https:// + promptAvoid loading configuration or behavior-controlling content from runtime URLs. Bundle required configurations locally or pin remote config to versioned, integrity-verified endpoints.
Likely FP if the URL in the match is a documentation link or example URL (e.g., example.com) rather than an actual runtime-fetched configuration endpoint.
Detects references to raw.githubusercontent.com on mutable branches like main/master
raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/Replace GitHub raw.githubusercontent.com references with pinned commit SHAs instead of branch names (e.g., /commit-sha/file instead of /main/file). Branch references are mutable.
Likely FP if the raw GitHub URL points to a versioned release tag in a well-known repository, though even tags are technically mutable.
