From the README

# open-codebase-index

> Search a codebase by meaning, then follow the result into definitions, callers, and dependency paths.

`open-codebase-index` is a local semantic code index for OpenCode, Jcode, Pi, Codex, Claude Code, and other MCP clients. It combines embeddings, BM25 keyword search, branch-aware filtering, symbol lookup, and a call graph behind agent-friendly tools.

New installs should use `open-codebase-index` and `open-codebase-index-mcp`. The legacy package `opencode-codebase-index` and `opencode-codebase-index-mcp` remain supported aliases.

For terminal use outside an MCP client, install the package globally and use the concise `ocbi` command:

```bash
npm install -g open-codebase-index
ocbi status --project /path/to/repo --host jcode
ocbi search "retry recovery" --project /path/to/repo
```

`cbi` remains available as a compatibility alias. `ocbi` provides status, indexing, search, definition lookup, and direct caller or callee inspection. See [Installation and host set
