mindnode-ui

mindnode-ui is a skill for Claude Code, Codex from tdimino/claude-code-minoan. It costs 76 tokens per session (1,287 once invoked), scanned A, original, MIT.

A guide for building React interfaces for visual mind maps, where ideas appear as connected nodes on a canvas. It also covers an outline view, layouts, themes, and keyboard controls.

In plain words
What is it for?
Use it to build brainstorming tools, node diagrams, and mind maps with different node shapes, radial or linear layouts, focus mode, and shortcuts.
Why use it?
It provides patterns for organizing non-linear ideas while still offering a readable list view and ways to navigate without relying on a mouse.

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.

Security

Grade A, and why

mindnode-ui 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 5d 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.

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MindNode UI

Build mind mapping interfaces inspired by MindNode — the Apple-native visual thinking app by IdeasOnCanvas GmbH. This skill encodes MindNode's design system, interaction model, and layout algorithms, adapted for React + ReactFlow + Zustand + Tailwind CSS 3.

Key Design Principles

  • Visual-first thinking — spatial canvas for non-linear ideas, outline for linear structure
  • Apple-native aesthetic — soft rounded elements, generous whitespace, purple accent (#6C63FF)
  • ADHD-friendly — Focus mode isolates one subtree, Quick Entry captures ideas fast
  • Keyboard-driven — Tab=child, Return=sibling, arrows=navigate, no mouse required

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.
