vinilana/jev-eval-agent

Compares LLM tool selection with Jev routing in a 100-tool agent.

Automated README summary

Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A personal-assistant agent built with eve (Vercel), served through OpenRouter, containing 100 mocked tools. It benchmarks how many steps the agent needs when the LLM picks the tool itself versus when Jev picks it.

How it uses Jev

In jev-classifier mode, Jev is called before every model step with state { user_request, actions_taken[], assistant_said[] }. It answers next_tool (choice over 100 tools + respond_to_user) and done (noul). If respond_to_user is chosen but done is below JEV_DONE_THRESHOLD, the router blocks the reply and exposes the next-best tool.

Primitives:choicenoul

Technique worth stealing

Confidence-gated routing: a noul 'done' check gates the choice's respond_to_user, falling back to the next-best tool.

Try it

cp .env.example .env.local, fill keys, npm install, then npm run eval or AGENT_MODE=jev-classifier npm run eval.

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.
