taint-instrumentation-assistant
Sets up taint tracking by defining sources, sinks, and sanitizers from Project CodeGuard's input-validation taxonomy, then configures the target tool (CodeQL, Semgrep, custom instrumentation). Use when wiring taint analysis into CI, when the user asks for taint tracking, or when you need a source/sink catalog for a specific language.

2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill's workflow explicitly instructs the agent to "Pull the language-specific source/sink/sanitizer lists from the CodeGuard rules" (see the Upstream GitHub link to project-codeguard in SKILL.md), which requires ingesting public third-party repository content that will directly shape tool configuration and behavior.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs runtime fetching of Project CodeGuard rules from https://github.com/cosai-oasis/project-codeguard/tree/main/skills/software-security to obtain the source/sink/sanitizer lists that directly determine the agent's taint-analysis rules and behavior, making this an external resource fetched at runtime that controls the agent's instructions.
