Fetch and display AI-powered SAST findings from the Endor Labs platform. Default path is summary-only (aggregated counts + clusters); full masked listing runs only when the user asks to drill down (speed and token use). Use when the user says "AI SAST results", "AI SAST findings", "AI static analysis", "endor ai sast", "show AI SAST", or wants pre-computed AI-driven code security findings. Do NOT use for running a new SAST scan (/endor-sast), viewing general findings (/endor-findings), or explaining a specific CVE (/endor-explain).
