3 findings — 1 high severity, 2 medium severity. You should review these findings carefully before considering using this skill.
W007: Insecure credential handling detected in skill instructions
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
Insecure credential handling detected (high risk: 1.00). The workflow explicitly requires reviewing code for "hardcoded secrets" and including "Code Snippet" for each finding, which would force the agent to extract and embed secret values from the repository verbatim into the generated report.
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: 0.85). The skill’s runtime workflow fetches and reads security rule markdown from the public GitHub repository `Project CodeGuard` (e.g., `.../sources/rules/core/*.md` and `.../sources/rules/owasp/*.md`), so outsider-authored free text from those pages is ingested into the agent’s LLM context.
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: 1.00). The skill explicitly requires fetching and reading Project CodeGuard rule files at runtime (e.g., https://github.com/cosai-oasis/project-codeguard/tree/main/sources/rules/core and https://github.com/cosai-oasis/project-codeguard/tree/main/sources/rules/owasp), which are mandatory and directly control the agent's prompt/instruction behavior.
