ostk — the kernel

RepoWhat it is
ostk.aiProduction release mirror. Signed binaries, governance bail, prime key.
ostk-siteSource for ostk.ai. Astro.
libostkUserspace client library for the ostk kernel.
homebrew-ostkHomebrew tap. Auto-updated on release.
ostk-recallLocal-first hybrid retrieval MCP server — model2vec embeddings + LanceDB + Tantivy BM25 + SQLite. One binary; hybrid search across markdown, code, and Claude Code sessions.
ostk-cacheContext-aware caching proxy for Anthropic and OpenAI. Drop-in for Claude Code, Codex, Cursor, and custom harnesses.
osteakElm-style architecture for ratatui — you bring the loop.

Companion tools

RepoWhat it is
prismProject a canonical .agents/ directory into every AI coding tool's config (Claude, Cursor, Gemini, Cline, Continue, Windsurf, Copilot, AGENTS.md).
docfreshTrack documentation freshness against source code.

Benchmarks

RepoWhat it is
find-the-needle23 Docker benchmarks. Submit broken Dockerfiles, watch models fix them. Leaderboard at needle-bench.cc.

File Context Protocol (FCP)

MCP servers that expose verb-based DSLs over complex file formats. Each driver exposes the semantic operations a format supports rather than raw file I/O.

Frameworks

RepoLanguage
fcpProtocol spec
fcp-coreTypeScript + Python shared framework
fcp-core-rustRust shared framework

Drivers
