What is agentlink-visualizer CLAUDE.md?

Project instructions for a React and TypeScript web app that draws a graph of links between AGENTS.md and CLAUDE.md instruction files. It scans a selected folder, finds those files, extracts path references, and displays the connections.

Developing or maintaining the instruction-file visualizer, including file parsing, path resolution, graph construction, and the D3-based graph view.

They explain how folders are scanned and how file references become graph links, which helps contributors change the app without breaking its data flow. They also list the commands for installing, developing, building, and previewing it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00561	$0.00561
Opus 5.5	$0.00224	$0.00224
Sonnet 5.5	$0.00112	$0.00112

Security

Grade A, and why

agentlink-visualizer CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture

This is a React 19 + TypeScript + Vite application that visualizes cross-references between AGENTS.md and CLAUDE.md files in a repository using a force-directed graph.

Core Data Flow

User selects a folder via File System Access API (showDirectoryPicker)
App.tsx recursively scans for AGENTS.md/CLAUDE.md files only (memory efficient)
services/fileParser.ts extracts @path references and builds graph data
components/GraphView.tsx renders D3 force-directed graph

Key Files

App.tsx - Main component: folder scanning, file selection, layout
types.ts - TypeScript interfaces: AgentFile, GraphNode, GraphLink, FileTreeNode
services/fileParser.ts - Link extraction (extractLinks), path resolution (resolvePath), graph building (buildGraphData), tree building (buildFileTree)
components/GraphView.tsx - D3.js force simulation with zoom/drag
components/FileTree.tsx - Recursive file explorer sidebar
components/MarkdownViewer.tsx - Content display with link highlighting

Reference Parsing

The app parses two link formats:

@path/to/file - CLAUDE.md style references
[[wiki-style]] - Legacy AGENTS.md style

Path resolution supports absolute (@/path), explicit relative (@./path, @../path), and implicit root relative (@path).

Tech Stack

React 19 with hooks (useState, useMemo, useEffect, useRef)
TypeScript 5.8
Vite 6 with React plugin
Tailwind CSS 4 via PostCSS (@tailwindcss/postcss)
D3.js 7 for force-directed graph visualization
Lucide React for icons
File System Access API (Chrome/Edge only)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
