CRITICAL
Curl or wget piped to shell
L70

Detects downloading scripts piped directly to a shell interpreter

curl -fsSL https://raw.githubusercontent.com/jacob-bd/universal-skills-manager/main/install.sh | sh
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
L70

Detects patterns of downloading and piping to shell execution

curl -fsSL https://raw.githubusercontent.com/jacob-bd/universal-skills-manager/main/install.sh | sh
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
Runtime URL controls agent behavior
L70

Detects skills fetching external URLs to use as runtime instructions

curl -fsSL https://raw.githubusercontent.com + prompts
FIX

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.

FP?

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.

LOW
Chained shell command execution
L70

Detects chained commands using shell operators with dangerous operations

curl -fsSL https://raw.githubusercontent.com/jacob-bd/universal-skills-manager/main/install.sh | sh
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
Mutable GitHub raw content reference
L70

Detects references to raw.githubusercontent.com on mutable branches like main/master

raw.githubusercontent.com/jacob-bd/universal-skills-manager/main/
FIX

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.

FP?

Likely FP if the raw GitHub URL points to a versioned release tag in a well-known repository, though even tags are technically mutable.

LOW
External API response used without validation
L81

Detects patterns where external API responses are used directly without validation or sanitization

API response + without a specific query, use
FIX

Validate and sanitize all data received from external APIs before using it in tool operations or agent prompts. Implement schema validation and treat API responses as untrusted input.

FP?

Likely FP if the match is a truncated table cell or documentation fragment that mentions API responses in a descriptive context, not actual unvalidated data processing.

LOW
Runtime URL controlling behavior
L192

Detects URLs fetched at runtime that control or influence agent behavior without pinning

get one at https:// + config
FIX

Avoid loading configuration or behavior-controlling content from runtime URLs. Bundle required configurations locally or pin remote config to versioned, integrity-verified endpoints.

FP?

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.

LOW
Remote SDK or script fetch as agent input
L211

Detects fetching remote documentation or code to load as agent context

curl -X GET  + https://raw.githubusercontent.com/{user}/{repo}/{branch}/{path}/SKILL.md
FIX

Pin 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.

FP?

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.
