Seewhatyourcodeactuallymeans

Paste a GitHub URL. Claude agents map your entire codebase into an interactive 3D causal graph — a galaxy of files, connected by what actually imports, calls, and depends on what.

Add your Anthropic API key in settings to analyze a new repo.

In ninety seconds

From a URL to a graph you can actually read.

Ingest

Paste any GitHub URL

Public or private. Octokit fetches the repo tree client-side with your PAT. No upload step.

Analyze

Four Claude agents, parallel

Structure · Dependency · Semantic · Oracle — each with a specialized system prompt. Results stream into the graph as they arrive.

Visualize

3D causal graph

Every file placed, every import traced, layered by semantic role — infra, data, logic, API, UI, tests, config.

Ask

"What breaks if I delete this module?"

Click any node. Oracle answers using the graph as context — extended thinking for blast-radius simulation before you touch the code.

Works in every agent

Web, CLI, Claude Code plugin. Any agent that can run a shell command can map a repo.

Four Claude Opus 4.7 agents run in parallel on every repo you map. They share their findings over context handoffs — Structure feeds Dependency, Dependency feeds Semantic, Semantic feeds Oracle.
