GraphARC Open-Source Framework: Building Controllable Investigation Agents with Local Qwen 8B
Desperate-Ad-9679 · reddit · 2026-08-06
A developer open-sourced GraphARC, a LangGraph-based CLI tool that leverages local small models like Qwen3:8B to autonomously plan multi-node investigation graphs.
Key Mechanics:
- Deterministic Admission Gate: Proposed execution graphs must pass five checks (registry, policy, budget, depth, acyclicity) before execution.
- Refusals as a Feature: When asked to perform policy-violating actions (e.g., rolling back a deploy), the system uses structured refusals to steer the model towards safe, read-only investigations with a full audit trail.
- Dynamic Topology: Supports model-generated parallel investigation branches merging at a single report node.
All states are logged to an append-only JSONL file, ensuring perfect consistency between the dashboard and audit logs. Requires no API key and supports local running via Ollama.
