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.
