## What it does

The skill documents a complete `mcp-vector-search` flow: install the package with `pip`, run setup, build a codebase index, and issue semantic queries. The setup command detects project languages, creates configuration, indexes the repository, and prepares MCP connectivity for tools such as Claude Code and Cursor.

It covers regular and forced indexing, full or path-based reindexing, status checks, and diagnostics. Auto-indexing can be configured, inspected, or removed, while `MCP_ENABLE_FILE_WATCHING=true` keeps file changes visible to the integration. The workflow depends on `mcp-vector-search` being installed first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add bobmatnyc/claude-mpm-skills --skill vector-search-workflows -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/vector-search-workflows/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/vector-search-workflows/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bobmatnyc/claude-mpm-skills --skill vector-search-workflows -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/vector-search-workflows/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bobmatnyc/claude-mpm-skills --skill vector-search-workflows -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/vector-search-workflows/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bobmatnyc/claude-mpm-skills vector-search-workflows
```

2. **Manually: put the files in place**
- File: `.github/skills/vector-search-workflows/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add bobmatnyc/claude-mpm-skills --skill vector-search-workflows -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/bobmatnyc/claude-mpm-skills --path toolchains/ai/techniques/vector-search-workflows
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/vector-search-workflows/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add bobmatnyc/claude-mpm-skills --skill vector-search-workflows -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/bobmatnyc/claude-mpm-skills/tree/HEAD/toolchains/ai/techniques/vector-search-workflows/SKILL.md

## When to use it
- index a repository for semantic code search
- locate code by describing its behavior
- rebuild the index after parser or dependency changes
- configure automatic reindex checks
- connect vector search through MCP

## Example prompts
- Set up `mcp-vector-search` for this repository and configure its MCP integration.
- Search the codebase for the logic that handles authentication errors.
- Check the index, then force a reindex after the parser changed.

# Vector Search Workflows (MCP Vector Search)

## Overview

Use `mcp-vector-search` to index codebases into ChromaDB and search via semantic embeddings. The recommended flow is `setup` (init + index + MCP integration), then `search`, and use `index` or `auto-index` to keep data fresh.

## Quick Start

```bash
pip install mcp-vector-search
mcp-vector-search setup
mcp-vector-search search "authentication logic"
```

`setup` detects languages, initializes config, indexes the repo, and configures MCP integrations (Claude Code, Cursor, etc.).

## Core Commands

### Indexing

```bash
mcp-vector-search index
mcp-vector-search index --force
mcp-vector-search index reindex --all --force
mcp-vector-search index reindex path/to/file.py
```

### Auto-Index Strategies

```bash
mcp-vector-search auto-index setup --method all
mcp-vector-search auto-index status
mcp-vector-search auto-index check --auto-reindex --max-files 10
mcp-vector-search auto-index teardown --method all
```

### Search

```bash
mcp-vector-search search "error handling patterns"
mcp-vector-search search "vector store initialization"
```

### Status + Doctor

```bash
mcp-vector-search status
mcp-vector-search doctor
```

## MCP Integration Pattern

`setup` uses native `claude mcp add` when available, otherwise falls back to `.mcp.json`.

Typical `.mcp.json` entry:

```json
{
  "mcpServers": {
    "mcp-vector-search": {
      "type": "stdio",
      "command": "uv",
      "args": ["run", "mcp-vector-search", "mcp"],
      "env": {
        "MCP_ENABLE_FILE_WATCHING": "true"
      }
    }
  }
}
```

## Reindex Triggers

- Dependency updates or parser changes
- Large refactors
- Adding new languages or file extensions
- Tool upgrades (version tracking triggers reindex)

## Local Patterns

- Use `uv` for dev installs: `uv sync --dev`
- Use `setup --force` to rebuild config + index after tool upgrades
- Keep file watching on via `MCP_ENABLE_FILE_WATCHING=true`
