**The Egonex-AI Understand Anything plugin is built as a PNPM monorepo featuring three distinct layers—a core static-analysis engine, a React-based dashboard UI, and platform-specific plugin glue—connected by a parallelized multi-agent pipeline that combines deterministic tree-sitter parsing with LLM-enhanced semantic analysis.**

The **Egonex-AI/Understand-Anything** repository provides a sophisticated code comprehension tool designed to analyze any codebase and generate interactive knowledge graphs. The plugin architecture follows a strict separation of concerns that enables deployment across 15+ AI coding platforms including Claude Code, Cursor, and Copilot.

## Monorepo Structure

The plugin organizes code into three primary packages under `understand-anything-plugin/`:

- **`packages/core`** – Houses the static-analysis engine, schema definitions, and graph generation logic. This layer implements the deterministic **tree-sitter** parser using `web-tree-sitter` (WebAssembly version) for browser compatibility, and manages the persistent knowledge-graph format.
- **`packages/dashboard`** – A React + TypeScript SPA that renders the force-directed graph visualization. It consumes the knowledge graph via dev-server endpoints and provides layered visualisation, fuzzy search, and guided tours.
- **`src/`** – Contains the plugin glue including skill definitions, multi-agent orchestration, and CLI entry points. The main entry point at [`src/index.ts`](https://github.com/Egonex-AI/Understand-Anything/blob/main/src/index.ts) registers commands like `/understand`, `/understand-dashboard`, and `/understand-chat`.

## Multi-Agent Pipeline

When a user invokes **`/understand`**, the plugin spins up a **pipeline of specialized agents** that run in parallel where possible:

1. **`project-scanner`** – Discovers all files and detects languages/frameworks.
2. **`file-analyzer`** – Extracts functions, classes, and imports; creates graph nodes and edges.
3. **`architecture-analyzer`** – Derives logical layers (API, Service, Data, UI) from directory grouping and import patterns.
4. **`tour-builder`** – Generates guided walkthroughs of the architecture.
5. **`graph-reviewer`** – Validates graph completeness and referential integrity.
6. **`domain-analyzer`** *(optional)* – Extracts business-domain concepts and flows.
7. **`article-analyzer`** *(optional)* – Parses external wiki/articles for additional entities.

Each agent writes intermediate results to `.understand-anything/intermediate/`, with the final knowledge graph persisted as [`.understand-anything/knowledge-graph.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json).

## Core Engine Implementation

The core engine in `packages/core` implements a hybrid parsing strategy:

**Tree-sitter Integration** – Every source file undergoes deterministic parsing via `web-tree-sitter` to build a concrete syntax tree. This WebAssembly-based approach ensures the parser runs identically in both Node.js environments and browsers.

**LLM Hybrid Layer** – After static parsing, the LLM consumes the syntax tree plus original source to generate human-readable summaries, tags, and layer labels. This guarantees repeatable structural data while capturing semantic intent.

**Schema Validation** – Every generated graph undergoes validation against strict JSON schemas; errors surface as warning banners in the dashboard.

**Browser-Safe Exports** – The core's public API deliberately splits into browser-safe sub-path exports (`./search`, `./types`, `./schema`) so the dashboard never bundles Node-only modules.

## Dashboard UI Architecture

The dashboard at `packages/dashboard` renders a **force-directed layout** (75% graph, 360px sidebar) with several interactive features:

- **Layer Colour-Coding** – Visual distinction between API (red), Service (blue), Data (green), and Infrastructure layers.
- **Side-Panel Tabs** – `Info` and `Files` tabs displaying node details, guided tour steps, or a file explorer built from the graph structure.
- **Code Viewer** – A Prism-based viewer that slides up on node click, with expand-to-full-screen capability.
- **Styling** – Built with **Tailwind v4** following the "dark-luxury" theme (deep blacks, gold accents).

The dashboard consumes the persisted graph via the [`/file-content.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main//file-content.json) dev-server endpoint.

## Platform Integration Layer

The plugin ships with **auto-discovery manifests** for supported platforms:

- **Claude Code** – [`.claude-plugin/plugin.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.claude-plugin/plugin.json)
- **Cursor** – [`.cursor-plugin/plugin.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.cursor-plugin/plugin.json)
- **VS Code + Copilot** – [`.copilot-plugin/plugin.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.copilot-plugin/plugin.json)
- **Copilot CLI** – Standard CLI installation
- **Others** – [`install.sh`](https://github.com/Egonex-AI/Understand-Anything/blob/main/install.sh) script supporting 15+ platforms including Codex, OpenCode, and Gemini

The [`install.sh`](https://github.com/Egonex-AI/Understand-Anything/blob/main/install.sh) script creates appropriate symlinks and registry entries for each target environment.

## Data Flow Overview

The complete analysis workflow follows this deterministic sequence:

1. **Invocation** – User runs `/understand`, triggering `project-scanner` to discover files.
2. **Parsing** – `file-analyzer` parses each file with tree-sitter, extracting imports, functions, and classes.
3. **Layer Assignment** – `architecture-analyzer` groups files by directory patterns (e.g., `routes → api`, `services → service`) and computes import adjacency to emit 3-10 logical layers.
4. **Tour Generation** – `tour-builder` creates ordered "learning tours" based on dependency direction.
5. **Validation** – `graph-reviewer` validates the graph and optionally performs full LLM review.
6. **Persistence** – Results written to [`.understand-anything/knowledge-graph.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json).
7. **Visualization** – Dashboard reads the JSON and renders the interactive interface.

## Frequently Asked Questions

### What parser does the Understand Anything plugin use for static analysis?

The plugin uses **tree-sitter** via the `web-tree-sitter` WebAssembly package to parse every source file into a concrete syntax tree. This ensures deterministic parsing that behaves identically across Node.js and browser environments, as implemented in `packages/core`.

### How does the plugin support multiple AI coding platforms?

The repository includes platform-specific manifest files (e.g., [`.claude-plugin/plugin.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.claude-plugin/plugin.json), [`.cursor-plugin/plugin.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.cursor-plugin/plugin.json)) and an [`install.sh`](https://github.com/Egonex-AI/Understand-Anything/blob/main/install.sh) script that handles auto-discovery and symlink creation for 15+ platforms including Claude Code, Cursor, GitHub Copilot, Codex, and Gemini.

### Where does the plugin store analysis results?

Intermediate agent results are written to `.understand-anything/intermediate/`, while the final validated knowledge graph is persisted as [`.understand-anything/knowledge-graph.json`](https://github.com/Egonex-AI/Understand-Anything/blob/main/.understand-anything/knowledge-graph.json). The dashboard reads this JSON file via a dev-server endpoint to render the visualization.

### What is the role of the architecture-analyzer agent?

The `architecture-analyzer` agent performs a two-phase process: first, it computes structural analysis including directory groups, import adjacency, and pattern matches (e.g., mapping `routes/` to `layer:api`); second, it assigns semantic layer labels to produce 3-10 logical architecture layers such as API, Service, Data, and Infrastructure.
