tessl review fix ./.agents/skills/boris/SKILL.mdE005: 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
The update check instructs the user to download an installation script from howborisusesclaudecode.com via curl, which is a suspicious domain attempting to mimic legitimate developer tools.
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 contains an update check instructing the agent to fetch instructions and installation scripts from `howborisusesclaudecode.com`, which constitutes a weak or unknown third-party operational dependency.
