Automated README summary
Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A ComfyUI custom node that runs restricted Python-like scripts to handle math, logic, text editing, conditional routing, resolution selection, and filename generation, with optional AI decision functions.
How it uses Jev
In MultiOutputScript (Jev), scripts call jev.yes, jev.choice, or jev.score on a text state to get probabilities and branch in if statements. Results drive outputs like width/height or routing. Backends: TypeSafe API, local GGUF, Clef, or d1.
Primitives:choicescorenoul
Technique worth stealing
Ask typed yes/no, choice, and score questions about a state and use the returned probabilities directly in script conditionals.
Try it
Clone into ComfyUI/custom_nodes, restart ComfyUI. For Jev, pip install typesafe-sdk and add api_key.txt.
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.
