Detects patterns of downloading and piping to shell execution
curl -s https://raw.githubusercontent.com/babashka/babashka/master/install | bash Download the file first, verify its integrity (checksum, signature), inspect it, then run it. Prefer package managers over raw downloads. Never fetch-and-run in one step.
Likely FP if the target is a well-known installer (e.g., rustup, Homebrew) from its canonical HTTPS domain, though the pattern is inherently risky.
Detects downloading scripts piped directly to a shell interpreter
curl -s https://raw.githubusercontent.com/babashka/babashka/master/install | bash Download the script first, inspect it, verify its checksum, then run it. Do not pipe curl/wget output directly to sh/bash. Prefer package manager installs.
Likely FP if the download is from a well-known installer domain (e.g., brew.sh, rustup.rs), though this pattern is inherently risky even with trusted sources.
Detects skills fetching external URLs to use as runtime instructions
curl -s https://raw.githubusercontent.com + Configuration Pin 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 chained commands using shell operators with dangerous operations
curl -s https://raw.githubusercontent.com/babashka/babashka/master/install | bash Break chained commands into discrete, individually validated steps. Avoid piping untrusted output directly into a shell interpreter.
Likely FP if the matched text is a documentation example showing a common installer one-liner for a well-known tool with a canonical URL.
Detects references to raw.githubusercontent.com on mutable branches like main/master
raw.githubusercontent.com/babashka/babashka/master/ 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.
Detects system-level package installation via brew, apt, yum, or dnf
brew install b Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.
Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.
Detects URLs fetched at runtime that control or influence agent behavior without pinning
Get an API key:** Sign up at [Tabstack Console](https:// + schema Avoid 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.
