CodeSeek

Code intelligence CLI tool for Claude Code. AST-based call graph analysis + semantic search — right from your terminal.

Quick Start

# Install via npm (handles setup wizard + binary download automatically)
npm install -g codeseek

# First run — interactive setup wizard configures your embedding model
codeseek

# Index your project
codeseek init

# Search code by symbol name
codeseek search main --limit 10

# Query call graph
codeseek callers main
codeseek callees process_data

# Register with Claude Code / Codex as MCP tools
codeseek install

# Check status
codeseek status

# Auto-index on git commits
codeseek install-hooks

Install

npm

npm install -g codeseek

The npm package ships a lightweight JS wrapper that handles:

Step	Description
First-run wizard	Interactive CLI prompts for embedding API token, model, and base URL
Binary download	Automatically pulls the correct Rust binary for your platform from GitHub Releases
Pass-through	All commands (init, search, callers, etc.) are forwarded to the native binary

Supported platforms:

Platform	Architecture
macOS	arm64 (Apple Silicon), x64 (Intel)
Linux	x64
Windows	x64

Homebrew (coming soon)

brew install CodeBendKit/tap/codeseek

From source

git clone https://github.com/CodeBendKit/codeseek.git
cd codeseek
./build.sh --release

build.sh compiles both the TypeScript wrapper (dist/) and the Rust binary, then installs to ~/.codeseek/bin/.

Commands

Command	Description
codeseek	First-time setup wizard (configures embedding model interactively)
codeseek init	Build/update code index (full on first run, MD5-incremental thereafter)
codeseek status	Index statistics: functions, files, last update
codeseek search <query>	Symbol name search (falls back from vector → graph name match)
codeseek callers <symbol>	Find functions that call this symbol
codeseek callees <symbol>	Find functions this symbol calls
codeseek list	List all indexed projects with paths
codeseek install	Register codeseek as MCP tools in Claude Code / Codex
codeseek uninstall	Remove MCP integration
codeseek uninit	Delete the current project index
codeseek install-hooks	Install git hooks (post-commit/post-merge → codeseek init)
codeseek serve --mcp	Start MCP server (stdio JSON-RPC, used by Claude Code internally)

All query commands support --json for machine-readable output.

Claude Code / Codex Integration

codeseek install

Writes MCP server config to:

Agent	Config file
Claude Code	~/.claude.json (global, all projects) or ./.mcp.json (project-local)
Codex CLI	~/.codex/config.toml

Claude Code auto-discovers these tools after restart:

Tool	Capability
codeseek_search	Find symbols by name
codeseek_callers	Trace upstream callers
codeseek_callees	Trace downstream callees
codeseek_status	Check index health

Remove integration:

codeseek uninstall

How It Works

codeseek search "auth middleware"
  → Detect project root (walk up to .git/)
  → Load index from ~/.codeseek/<project_hash>/
  → Graph-based name search (PetCodeGraph)
  → Output results

No daemon, no HTTP server. Every command is a standalone process.

Storage

• Config: ~/.codeseek/config.json (global, shared across all projects)
• Index: ~/.codeseek/<md5(project_root)>/
  • project.json — Project metadata (root path, indexed timestamp)
  • graph.bin — Serialized call graph (PetCodeGraph)
  • embeddings.lance/ — LanceDB vector data (optional, requires API token)
  • tantivy_bm25/ — BM25 full-text index (optional)
  • file_hashes.json — MD5 incremental tracking

Incremental Updates

codeseek init is idempotent:

• First run: Full AST parse → build graph → save
• Subsequent runs: MD5 comparison → only re-process changed files → merge with existing graph

# Install git hooks for automatic re-index on commit/merge
codeseek install-hooks

Configuration

~/.codeseek/config.json:

{
  "embedding": {
    "provider": "openai-compatible",
    "model": "Qwen/Qwen3-Embedding-4B",
    "api_token": "sk-...",
    "api_base_url": "https://api.siliconflow.cn/v1",
    "dimensions": 2560
  },
  "index": {
    "min_code_block_length": 16,
    "enable_reranker": false
  },
  "installed_hooks": {}
}

Set via the interactive wizard on first run, or create manually.
