Fix and improve this skill with Tessl
tessl review fix ./skills/whatsapp-automation/SKILL.mdW011: 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 workflow handles sending WhatsApp messages and interacting with the WhatsApp Business API, which involves incoming customer messages read via the integration, exposing the agent to outsider-authored free text.
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 references an external Model Context Protocol endpoint (https://rube.app/mcp) which serves as an operational configuration and runtime tool source, but lacks established official provenance, placing it in the high-risk tier.
