Self-evolving context database for AI agents, with a Jev rerank client.

Scoring & Ranking1.00Runner-up: Classification & Routing
Automated README summary

Automatically summarized from the README on 30 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

OpenViking is an open-source context database for AI agents, unifying knowledge, memory and skills in a virtual filesystem under viking://. Agents browse, search and edit context via ls, tree, read, write, grep and find.

How it uses Jev

A Jev rerank client scores each candidate document against the query using jev-latest at api.typesafe.ai; the returned probability is treated as relevance for reranking, since TypeSafe exposes no native rerank endpoint.

Primitives:score

Technique worth stealing

Use Jev's calibrated probability as a relevance score to rerank retrieved documents when no native rerank API exists.

Try it

uv tool install openviking --upgrade && openviking-server init, then use the ov CLI.

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.
