Suggest reviewing before use
Security
2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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). This skill's required workflow explicitly detects and ingests changed SKILL.md files from pull requests (e.g., "Detect changed SKILL.md files" and the various CI templates that run `tessl skill review --json <path>`), and it can optionally run `--optimize --yes` and commit optimized files back to the PR branch — meaning untrusted, user-generated repository/PR content is parsed and can directly influence automated tool actions and commits.
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 repeatedly run "npm install -g @tessl/cli" and then execute "tessl skill review" (and optionally "--optimize --yes"), meaning the workflow fetches and runs remote code from the Tessl npm package (e.g. https://www.npmjs.com/package/@tessl/cli), which is a required runtime dependency that can modify repo files.
