Jev's System One decision model wired into coding agent harnesses.

Automated README summary

Automatically summarized from the README on 8 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

An experimental plugin connecting Jev, TypeSafe's System One decision model, to coding agents like OpenCode and Claude Code. It picks skills, tools, subagents, models and browser actions. Not for production use.

How it uses Jev

Jev answers typed questions about which skill to load, which tool subset a step needs, whether to delegate to a subagent, and each browser_task click or value. It also picks the model tier and thinking effort. Results are used by the plugin to route work; if Jev is slow or unsure, it does nothing.

Primitives:choicescorenoul

Technique worth stealing

Gate mechanical steps up front so they get no skill, and fail open when Jev is unsure.

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.
