## AiDex - Persistent Code Index (MCP Server)
AiDex provides fast, precise code search through a pre-built index. **Always prefer AiDex over Grep/Glob for code searches.**
### Auto-Init Rule
**At the start of every session, check if \`.aidex/\` exists in the project directory.**
- If \`.aidex/\` does NOT exist → **automatically run \`aidex_init\`** to create the index. Do not ask, just do it.
- If \`.aidex/\` exists → use AiDex tools for all code searches.
### When to Use AiDex (instead of Grep/Glob)
| Task | Do NOT use | Use instead |
|------|-----------|-------------|
| Find a function/class/variable | \`Grep pattern="name"\` | \`aidex_query term="name"\` |
| See all methods in a file | \`Read entire_file.cs\` | \`aidex_signature file="..."\` |
| Explore multiple files | Multiple Read calls | \`aidex_signatures pattern="src/**"\` |
| Project overview | Many Glob/Read calls | \`aidex_summary\` + \`aidex_tree\` |
| What changed recently? | \`git log\` + Read | \`aidex_query term="X" modified_since="2h"\` |
### Available Tools
| Tool | Purpose |
|------|---------|
| \`aidex_init\` | Index a project (creates \`.aidex/\`) |
| \`aidex_query\` | Search by term (exact/contains/starts_with) |
| \`aidex_signature\` | Get one file's classes + methods |
| \`aidex_signatures\` | Get signatures for multiple files (glob) |
| \`aidex_update\` | Re-index a single changed file |
| \`aidex_summary\` | Project overview with entry points |
| \`aidex_tree\` | File tree with statistics |
| \`aidex_files\` | List project files by type |
| \`aidex_session\` | Start session, detect external changes |
| \`aidex_note\` | Read/write session notes |
| \`aidex_viewer\` | Open interactive project tree in browser |
### Why AiDex over Grep?
- **~50 tokens** per search vs 2000+ with Grep
- **Identifiers only** - no noise from comments/strings
- **Persistent** - index survives between sessions
- **Structure-aware** - knows methods, classes, types
