-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](#benchmarks)). Everything runs on CPU with no API keys, GPU, or external services. Run it as an [MCP server](#mcp-server) and any agent (Claude Code, Cursor, Codex, OpenCode, etc.) gets instant access to any repo, cloned and indexed on demand.

 ## Quickstart
 
+Your agent will automatically use Semble whenever it needs to find code. Instead of grepping with a keyword and reading full files, it queries in natural language (e.g. `"How is authentication handled?"`) and gets back only the relevant context. Semble can be set up as an MCP server or as a bash tool:
+
+### MCP
+
 Add Semble to Claude Code (requires [uv](https://docs.astral.sh/uv/getting-started/installation/)):
 
 ```bash
 claude mcp add semble -s user -- uvx --from "semble[mcp]" semble
 ```
 
-Once added, your agent will automatically use Semble whenever it needs to find relevant code. Instead of having to use grep with a keyword (e.g. `"authentication"`) and reading full files, it can query in natural language (e.g. `"How is authentication handled?"`) and immediately get back only the relevant context.
+Using another agent harness? See [MCP Server](#mcp-server) for setup instructions for Codex, OpenCode, Cursor, and other MCP clients.
+
+### Bash / AGENTS.md
+
+Install Semble first, then add the [code search snippet](#bash-integration) to your `AGENTS.md` or `CLAUDE.md`:

-### Sub-agent support
-
-Claude Code and Codex CLI lazy-load MCP tool schemas, so sub-agents cannot call `mcp__semble__search` directly. The fix is to invoke semble through the [CLI](#cli) via Bash instead.

-semble init
