The Open Container Initiative is an open governance structure for the express purpose of creating open industry standards around container formats and runtimes.

Established in June 2015 by Docker and other leaders in the container industry, the OCI currently contains three specifications: the Runtime Specification (runtime-spec), the Image Specification (image-spec) and the Distribution Specification (distribution-spec). The Runtime Specification outlines how to run a “filesystem bundle” that is unpacked on disk. At a high-level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle. At this point the OCI Runtime Bundle would be run by an OCI Runtime.

Fast and Accurate Code Search for Agents. Uses ~98% fewer tokens than grep+read.

Semble is a code search library built for agents. It returns the exact code snippets they need instantly, using ~98% fewer tokens than grep+read and cutting latency on every step. Indexing and searching a full codebase end-to-end takes under a second, with ~200x faster indexing and ~10x faster queries than a code-specialized transformer, at 99% of its retrieval quality (see benchmarks). Everything runs on CPU with no API keys, GPU, or external services.

Run it as an MCP server and any agent (Claude Code, Cursor, Codex, OpenCode, etc.) gets instant access to any repo, cloned and indexed on demand.

Give a coding agent its own disposable Linux machine, not yours. Disposable, network-restricted Linux VMs for AI coding agents.

clawk is a third option. cd into a repo, type clawk, and Claude Code (or Codex, or a shell) is working inside a disposable Linux VM (your code mounted in, root in the guest, no permission prompts) while your files, your keychain, and the rest of your machine stay out of reach. The agent gets its own machine instead of yours.
