CRITICAL
Curl or wget piped to shell
L32

Detects downloading scripts piped directly to a shell interpreter

curl \| bash
FIX

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.

FP?

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.

CRITICAL
Download-and-execute
L32

Detects patterns of downloading and piping to shell execution

curl \| bash
FIX

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.

FP?

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.

HIGH
Curl or wget piped to shell
L55

Detects downloading scripts piped directly to a shell interpreter

curl -s https://xyz.example.com/setup.sh | bash
FIX

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.

FP?

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.

HIGH

L55

FP?

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.

LOW
Chained shell command execution
L32

Detects chained commands using shell operators with dangerous operations

curl \| bash
FIX

Break chained commands into discrete, individually validated steps. Avoid piping untrusted output directly into a shell interpreter.

FP?

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.

LOW
Chained shell command execution
L55

Detects chained commands using shell operators with dangerous operations

curl -s https://xyz.example.com/setup.sh | bash
FIX

Break chained commands into discrete, individually validated steps. Avoid piping untrusted output directly into a shell interpreter.

FP?

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.

LOW
Shell script file execution
L61

Detects execution of shell script files via bash/sh command or direct invocation

./install.sh
FIX

Replace 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.

FP?

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.
