Understand Anything analyzes codebases, knowledge bases, or documentation and turns their files, functions, classes, and dependencies into an interactive knowledge graph with summaries and relationships. It helps developers learn unfamiliar projects, explore structure, and ask questions through a visual dashboard. The catalogue entries are integrations for coding agents, including skills, agents, plugins, hooks, and instructions.

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 | $0.01645 | $0.01645 |
| Opus 5 | $0.00822 | $0.00822 |
| Sonnet 5 | $0.00329 | $0.00329 |
| Haiku 4.5 | $0.00164 | $0.00164 |
Grade C, and why
Understand-Anything CLAUDE.md scanned grade C with 1 finding 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 9d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Understand Anything
Project Overview
An open-source tool combining LLM intelligence + static analysis to produce interactive dashboards for understanding codebases.
Prerequisites
- Node.js >= 22 (developed on v24)
- pnpm >= 10 (pinned via
packageManagerfield in rootpackage.json)
Architecture
- Monorepo with pnpm workspaces
- understand-anything-plugin/ — Claude Code plugin containing all source code:
- packages/core — Shared analysis engine (types, persistence, tree-sitter, search, schema, tours, plugins)
- packages/dashboard — React + TypeScript web dashboard (React Flow, Zustand, TailwindCSS v4)
- src/ — Skill TypeScript source for
/understand-chat,/understand-diff,/understand-explain,/understand-onboard - skills/ — Skill definitions (
/understand,/understand-dashboard, etc.) - agents/ — Agent definitions (project-scanner, file-analyzer, architecture-analyzer, tour-builder, graph-reviewer)
Dashboard
- Dark luxury theme: deep blacks (#0a0a0a), gold/amber accents (#d4a574), DM Serif Display typography
- Graph-first layout: 75% graph + 360px right sidebar
- No ChatPanel or Monaco Editor
- Sidebar tabs:
Info(ProjectOverview default → NodeInfo when node selected → LearnPanel in Learn persona, composing) andFiles(FileExplorer tree built from the structural graph) - Code viewer: prism-react-renderer source viewer that slides up from the bottom on file node click; an expand button promotes it into a full-screen modal. Source content is fetched from the dev server's
/file-content.jsonendpoint, gated by access token + a graph-derived path allowlist - Schema validation on graph load with error banner
Agent Pipeline
- Agents write intermediate results to the data directory's
intermediate/subdirectory on disk (not returned to context) —.ua/intermediate/, or.understand-anything/intermediate/when that legacy directory is present - Agent model field is omitted from frontmatter so each platform falls back to its configured default —
inheritwas a Claude Code-only keyword that opencode (and similar tools) treated as a literal model id and rejected withProviderModelNotFoundError(see #167) /understandauto-triggers/understand-dashboardafter completion- Intermediate files cleaned up after graph assembly
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.

Understand-Anything CLAUDE.md is an instructions file published in the GitHub repository Egonex-AI/Understand-Anything (81,763 stars, last pushed today), licensed MIT. It adds 1,645 tokens to every session, about $0.0082 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
