Understand Anything: a Claude Code skill by EgonexAI
For developers joining or auditing a large codebase who want an explorable map of it. Skip it if your project is small or you can't spend many tokens on the first scan.
Before you install: The README's installer for other agents pipes a script from GitHub straight into bash; the Claude Code plugin route does not need it.

Most people install it straight from GitHub, where it has 91.8K stars, so its skills.sh count understates how widely it is used.

What does Understand Anything do?
Understand Anything is a set of 9 skills that maps a codebase into an interactive knowledge graph. The main /understand skill scans the project, analyzes files in batches with subagents, groups them into architecture layers, builds a guided tour, validates the graph and saves knowledge-graph.json in a .ua folder. Later runs only re-analyze changed files, and an optional post-commit hook keeps the graph current. Companion skills open the dashboard, answer questions with /understand-chat, explain one file, review a diff, write onboarding notes, map business domains, and graph a Karpathy-style Markdown wiki with /understand-knowledge. Output can be written in another language with --language.
When should you use Understand Anything?
Use it when
- You are new to a repository and need to see its architecture
- You want to ask questions about how a flow works
- You want an onboarding guide drawn from the actual code
Skip it when
- The project is a few files you can read yourself
- You can't afford a token-heavy first scan of a big repo
What it needs and what it can touch
You need
- Node.js 22+ and pnpm 10+
What it can do
- Runs shell commands (git, pnpm install and build, Node scripts)
- Writes the graph and its config to a .ua folder in your project
- Can add a post-commit hook when you turn on auto-update
From reading its instructions, not from running it.
Why it scores 63
Strongest on upkeep (100 of 100), weakest on adoption (36).
Is Understand Anything safe to install?
Every scanner that checked it passed it. Scanners often miss what other scanners catch, and a skill can change after a scan. Read its source before you install it.
