### Description (declared)

# 🌐 Epicenter

**Name a symbol. See everything that shakes.**

Epicenter parses a Python codebase into a dependency graph, then walks that graph *backwards* to answer the question developers actually ask before touching code:

> **"If I change this, what breaks?"**

It finds indirect callers that text search cannot see, tells you which of them no test reaches, and exposes all of it over [MCP](https://modelcontextprotocol.io) so AI coding assistants can consult real structure instead of inferring it from grep.

---

## Why this exists

AI coding assistants reason about repository structure by searching text and guessing. They miss indirect callers, inherited overrides, and cross-module chains. A parsed call graph doesn't — it knows that editing `fetch_graph_data` reaches `CuriosityEngine.__init__` two hops away, and it can show the chain.

That precision is the product. The graph is the means.

---

## 🚀 Quick start

```bash
pip install epicenter-mcp
```

Index a codebase, then ask:

```bash
epicenter index /path/to/repo
epicenter impact save_user
```

With more than one codebase indexed, name which to query: `--realm /path/to/repo`.

```
Changing db.save_user could affect 5 symbol(s):

  ── directly ──
    api.create_account  (function, 3 dependents)  [UNTESTED]
  ── 2 hops away ──
    web.signup_handler  (function, 0 dependents)
      via web.signup_handler <- api.create_account <- db.save_user

  1 of 5 affected symbol(s) have no test reaching them.
```

| Command | Answers |
|---|---|
| `impact <symbol>` | What breaks if this changes |
| `deps <symbol>` | What this relies on — the code to read first |
| `coverage <symbol>` | Which tests reach it |
| `coupling <symbol>` | What historically changes alongside it |
| `dead` | Symbols no entrypoint or test can reach |
| `find <query>` | Look up a symbol's qualified name |
| `index <path>` | Parse a codebase into the graph |
| `history [path]` | Mine git history for change coupling |
| `stats` | Graph size, entrypoi…
