Fix and improve this skill with Tessl
tessl review fix ./benchmarks/gdpval/skills/pptx-validation-fallback/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
This skill’s runtime workflow reads the user-supplied .pptx file via `run_shell`/`python-pptx` (extracting slide text/title), so the LLM ingests outsider-authored free text when the presentation document was authored by someone other than the operating user.
