docgraph

A powerful lint tool and graph generator designed to build and verify directed graphs embedded in standard Markdown files. docgraph ensures your documentation is consistent, traceable, and AI-ready.

Overview

docgraph treats Markdown blocks as nodes in a graph. By using HTML anchors (<a id="..."></a>) and standard Markdown links, you can define structured relationships (edges) between documents. This enables automated traceability across your entire documentation suite—from business actors and use cases down to technical requirements and architecture decisions.

For a comprehensive guide on concepts, architecture, and specifications, please refer to the Documentation Overview.

Key Features

• Graph Validation: Automated checks for broken links, duplicate IDs, and relationship rule violations defined in docgraph.toml.

• Template Validation: Enforce consistent documentation structure using Markdown templates with wildcard support.

• Traceability Analysis: Tools to search, trace, and describe complex node relationships.

• AI-Agent Ready: Built-in support for GraphRAG knowledge construction. AI Agents can consume docgraph outputs to assist in documentation and development workflows.

• Modern IDE Integration: A dedicated VS Code plugin with full LSP support. Configuration changes (docgraph.toml, .gitignore) are automatically reflected in real-time.

Getting Started

Follow these steps to set up docgraph for your project.

Step 1: Install CLI Binary

docgraph requires the CLI binary to be installed on your system for all use cases (CLI, AI, and IDE).

macOS / Linux (x86_64, aarch64):

curl -fsSL https://raw.githubusercontent.com/sonesuke/docgraph/main/install.sh | bash

Windows (PowerShell):

powershell -c "irm https://raw.githubusercontent.com/sonesuke/docgraph/main/install.ps1 | iex"

Or build from source: cargo install --path .

Step 2: Configure (docgraph.toml)

Create a docgraph.toml file in your project root to define your documentation architecture rules.

[node_types]
UC = { desc = "Use Case", template = "doc/templates/use_case.md" }
FR = { desc = "Functional Requirement", template = "doc/templates/functional.md" }
IF = { desc = "Interface", template = "doc/templates/interface.md" }

[references.FR]
rules = [
  { dir = "from", targets = [
    "UC",
  ], min = 1, desc = "Requirements must be derived from a use case" },
  { dir = "to", targets = [
    "MOD",
  ], min = 1, desc = "Requirements must be realized by a module" },
]

[references.IF]
rules = [
  { dir = "from", targets = [
    "UC",
  ], min = 1, desc = "Interfaces must be justified by a use case" },
  { dir = "from", targets = [
    "FR",
  ], min = 1, desc = "Interfaces must be defined by a functional requirement" },
]

Step 3: Set Up Your Environment

Choose how you want to interact with docgraph:

Option A: Claude Code

1. In a Claude chat, install the official plugin:

   /plugin marketplace add sonesuke/docgraph
   /plugin install docgraph-plugin@docgraph-claude-plugins
   

2. The AI agent will now automatically use the installed docgraph binary to analyze your documentation.

   Example Claude Interaction:

   You: "Build a knowledge graph from the current directory." Claude: "Building knowledge graph... Done. Found 15 nodes and 24 relationships."

   You: "What are the dependencies for UC_WRITE?" Claude: "UC_WRITE depends on ACT_USER and is realized by IF_CLI_LINT."

Option B: VS Code Extension

1. Download docgraph.vsix from GitHub Releases.
2. Install via Command Palette (Extensions: Install from VSIX...) or CLI:

   code --install-extension docgraph.vsix
   

Option C: Zed Editor Extension

1. Build the extension or download from releases:

   cd zed-extension && cargo build --release --target wasm32-wasip1
   

2. In Zed, run the command zed: install dev extension.

3. Select the zed-extension directory.

4. Create .zed/settings.json in your project root to enable the language server:

   {
     "languages": {
       "Markdown": {
         "language_servers": ["docgraph"],
         "format_on_save": "on"
       }
     }
   }
   

5. Note: Ensure the workspace is trusted (exit Restricted Mode) to allow the language server to start.

Option D: Standard CLI
