Fix and improve this skill with Tessl
tessl review fix ./.claude/skills/implement-posix-command/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
SKILL.md mandates runtime fetching/reading of GTFOBins pages and POSIX/reference materials (Step 1) from gtfo**bins.org** / other externally fetched files, which would be ingested as readable text into the agent’s LLM context unless explicitly sandboxed.
