tessl review fix ./.claude/skills/add-linear/SKILL.mdW007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
The skill explicitly prompts for OAuth client ID/secret and webhook signing secret and then injects those answers into an nc:env-set directive ({{...}}), which requires the agent to output the secret values verbatim into the generated .env content.
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
The required runtime workflow is webhook-driven for Linear issue comment threads (a Linear team webhook “Comment” event delivers free-text comments to the agent), so outsider-authored comment bodies are ingested at runtime via the Linear adapter.
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 installs and imports the external package @chat-adapter/linear@4.29.0 at runtime (installed in SKILL.md and exercised by the registration test), which fetches and executes third-party adapter code inside the agent process.
