Codebase Graphs: How TheAuditor and Brokk Fix AI Agent Context Collapse
AI coding agents hallucinate due to context collapse—data access problems, not model quality. TheAuditor (SQLite graph DB, triple-entry fidelity, cross-microservice taint tracking) and Brokk (in-memory AST cache, 1M LOC/minute) both implement pre-investigation: agents query codebase graphs before writing code. TheAuditor's "crash on silent data loss" contrasts with Brokk's faster but less framework-specific AST approach. The pattern—deterministic code structure access—is durable, though both ...

How ML Intern's Doom Loop Detection Stops AI Agents From Spinning — And How You Can Use It
Doom loops repeat identical tool calls with same results. HuggingFace's ml-intern doom_loop.py uses two algorithms (identical consecutive, repeating sequence) on ToolCallSignature with normalized args and result hash.
