mindmap

A tool for turning written information into visual mind maps. It can produce interactive React files or portable Markdown maps that open in a browser or compatible editor.

In plain words
What is it for?
Use it to map documents, ideas, plans, or knowledge. Choose an interactive map for exploration or a Markdown map for sharing outside Claude.
Why use it?
It helps when a long or complex subject is hard to understand as plain text. The visual structure makes topics, branches, and relationships easier to explore or share.

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

mindmap 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 417 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mind Map Generator

Generate interactive mind maps as React (.jsx) artifacts or portable Markmap (.md) files.

Output Modes

React (default): Interactive artifact with pan, zoom, collapse, palette switching, save button, edge-anchored connectors, and hover tooltips. Best for exploring in Claude.

Markmap (on request): Portable Markdown file that renders with markmap.js. Works in VS Code (Markmap extension), markmap.js.org, or any browser via npx markmap-cli. Best for sharing, embedding, and use outside Claude.

Trigger Markmap mode when the user says any of: "markmap", "markdown map", "--md", "portable format", "I want to open it outside Claude", "export as markdown map", "make it a .md", "markmap format"

If unclear, default to React.

When You Receive a Request

  1. Determine output mode — React (default) or Markmap (if triggered above)
  2. Check for deep mode: if the user says "--deep", "deep mode", "think harder", or "best possible structure", read references/judge-panel.md and follow that workflow. For rich documents (3000+ words with competing themes), you may proactively suggest it.
  3. Analyze the input content — extract the central topic and 4–7 main branches
  4. For React mode: Build the mindmapData object and generate a React artifact with ALL of the Mandatory Code below
  5. For Markmap mode: Generate a Markmap-flavored .md file following the Markmap Output section below
  6. Optionally read references/mindmap-best-practices.md for keyword compression examples

Content Analysis Strategy

  • Central topic: One noun phrase, 2–5 words max.
  • Main branches: 4–7 categories. 5–6 is the sweet spot.
  • Sub-branches: 2–5 items per branch. Keywords only, not full sentences.
  • Depth limit: 3 levels max (central → branch → sub-branch).

For long content: identify the main argument → group into thematic clusters → extract key evidence → discard redundancy. For broad topics: educational overview, foundational concepts first.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

mindmap is a skill published in the GitHub repository 0x-man/mindmap-skill (13 stars, last pushed 6d ago), licensed MIT. It adds 155 tokens to every session and 4,698 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Automatically fix broken OpenCLI adapters when commands fail. Load this skill when an opencli command fails — it guides you through collecting a trace artifact, patching the adapter, retrying, and filing an upstream GitHub issue after a verified fix. Works with any AI agent.

opencli-usage

Use at the start of any OpenCLI session — this is the top-level map of what opencli can do, how to discover adapters, what flags and output formats are universal, and which specialized skill to load next. Point here when an agent asks "what can opencli do?" or "how do I find the right command?".
