What it is
Skillbox is a self-hosted, versioned skills library for AI agents. It provides a Markdown/file editor, immutable revisions, profiles with grants, revocable client keys, HTTP MCP, and optional Jev recommendations using your own provider key.
How it uses Jev
Jev provides task-aware skill recommendations. It sends task text and authorized active skill descriptions to the selected provider (Vercel AI Gateway, TypeSafe AI, or OpenRouter). The result is used to rank skills; on failure, deterministic search with an explicit fallback reason is returned.
Primitives:choicescore
Technique worth stealing
Bounded catalog with score rubric, batched evaluation, and deterministic fallback on provider failure.
Try it
Run `node cli/skillbox.mjs recommend "Fix choppy scrolling in an Expo app"` after configuring a provider key.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
