Detects downloading scripts piped directly to a shell interpreter
curl -sSL https://raw.githubusercontent.com/fiatjaf/nak/master/install.sh | shDownload 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 patterns of downloading and piping to shell execution
curl -sSL https://raw.githubusercontent.com/fiatjaf/nak/master/install.sh | shDownload 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 references to raw.githubusercontent.com on mutable branches like main/master
raw.githubusercontent.com/fiatjaf/nak/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 chained commands using shell operators with dangerous operations
curl -sSL https://raw.githubusercontent.com/fiatjaf/nak/master/install.sh | shBreak 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 execution of shell script files via bash/sh command or direct invocation
bash
./scripts/derive-nostr.shReplace direct shell script execution with a language-native implementation or a sandboxed executor. If shell scripts must run, restrict them to a vetted allowlist with integrity checks.
Likely FP if the match references running a script that is part of the skill's own repository (e.g., ./setup.sh) with clear, auditable contents.

Detects npx executing packages from unverified sources without pinned versions
npx @didcid/keymaster Pin the npx package to an exact version (e.g., npx @scope/package@1.2.3). Unversioned npx commands can silently install a different or malicious package version.
Likely FP if the npx command targets a well-known package in documentation context, though unpinned versions are a real supply chain concern.
