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 workflows fetch and execute remote code at runtime — e.g., installing and running the Tessl CLI (npm package @tessl/cli, fetched from the npm registry) and pulling GitHub Actions like actions/checkout (https://github.com/actions/checkout) and peter-evans/create-or-update-comment (https://github.com/peter-evans/create-or-update-comment) — which are required for the skill to run and thus present a remote-code execution / supply-chain risk.
