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
A Rust CLI and stdio MCP server that finds open-source repositories and crates from natural-language queries, for developers and autonomous coding agents. It grounds results in live GitHub and crates.io metadata instead of generating text.
How it uses Jev
After fetching candidates, jev-scout sends one speculative fan-out call to the TypeSafe systemone endpoint. Jev scores architectural fit, estimates maintenance freshness, and picks the best match. Results are ranked by score times confidence and rendered as terminal cards or JSON.
Primitives:choicescorenoul
Technique worth stealing
Decouple discovery from decision: ground candidates in real registry metadata, then let one typed Jev fan-out call rank them.
Try it
cargo install jev-scout, export TYPESAFE_API_KEY, then run jev-scout "fast sqlite tui in rust".
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.
