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: 0.80). The skill's pipelines explicitly detect and run "tessl skill review --json <path>" on changed SKILL.md files from pull requests (see "Core Review Logic" in SKILL.md and the GitHub/Azure/CircleCI workflow templates) — meaning it ingests untrusted, user-contributed markdown from public forks/PRs and uses the review output to block builds, post PR comments, and update cache, so third-party content can materially influence actions.

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: 0.80). The CI templates install and run a third‑party CLI at runtime via "npm install -g @tessl/cli" (fetched from the npm registry, e.g. https://registry.npmjs.org or https://www.npmjs.com/package/@tessl/cli), which downloads and executes remote code that the skill depends on.
