Automated README summary
Automatically summarized from the README on 6 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An n8n community node that calls System One decision models (TypeSafe's Jev, Cloudflare's Clef) via OpenRouter, TypeSafe, Cloudflare Workers AI, or a custom endpoint. It lets n8n users add routing, classification, and guardrail decisions to workflows.
How it uses Jev
Jev evaluates a state (text or JSON) against typed questions (Noul yes/no, Choice, Score) and returns calibrated probabilities. The node maps these to simplified outputs like probabilities and confidence, optionally routes uncertain items to a second output, and can be used as an AI Agent tool.
Primitives:choicescorenoul
Technique worth stealing
Confidence-gated routing: send items to a separate output when any answer's confidence falls below a threshold.
Try it
Install @diegohh0411/n8n-nodes-system-one via n8n community nodes, then configure credentials and use the node.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
