E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
This points to a personal GitHub repository (https://github.com/huytieu/COG-second-brain.git) being used as an "upstream" remote for updating framework files and scripts (including an update script), which is risky because unknown/unverified repos can push malicious updates or executables without verification.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The skill adds and fetches from the upstream remote https://github.com/huytieu/COG-second-brain.git at runtime (git fetch / git checkout), which pulls upstream framework files — including skills and scripts — into the agent environment and can change agent prompts or introduce executable code.
