Detects patterns of downloading and piping to shell execution
curl ... \| bashDownload 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 ... \| bashDownload 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 instructions to decode and execute base64 content
Base64 payloads | Long base64 strings near exec/bash/evalRemove text that simulates multi-turn conversations or fake user/assistant message pairs. These patterns attempt to manipulate the agent by fabricating conversation history.
Likely FP if the matched text is documentation showing example conversations or API request/response formats for illustration purposes.
Detects Python subprocess and os.system calls for command execution in skill descriptions
os.system(Pass arguments as an explicit list instead of a shell string. Set shell=False and validate all user-supplied values before inclusion.
Likely FP if the match is in documentation explaining Python subprocess usage or in a description mentioning it as a topic.
Detects subprocess calls with shell=True which enables shell injection
shell=TrueReplace shell=True with shell=False and pass command arguments as a list. Validate and sanitize all inputs before passing to the shell.
Likely FP if the match is in documentation describing how subprocess works, or in a comment explaining shell risks rather than actual code.
Detects execution of shell script files via bash/sh command or direct invocation
bash install-hook.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.

bash install-hook.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 chained commands using shell operators with dangerous operations
curl ... \| bashBreak 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.
