Typed browser sub-tasks for coding agents via TypeSafe Jev.

Agent Decisions1.00Runner-up: Classification & RoutingFunnel
Automated README summary

Automatically summarized from the README on 27 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

jev-browse adds helpers to browser-harness so coding agents like Claude Code or Codex can hand off a whole website sub-task in one call, getting back the outcome or a typed reason for stopping.

How it uses Jev

Each browser step is decided by TypeSafe Jev, which answers typed questions in a few hundred milliseconds. One Jev request per decision; the agent is handed back control only for unknown values, risky clicks, unsupported frames or uploads, or sensitive data.

Primitives:choicescorenoul

Technique worth stealing

Offload per-step browser decisions to a small typed-question model so the calling agent only re-engages when it must.

Try it

uv tool install jev-browse && jev-browse install, then jev-browse doctor.

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.
