html-mind-map

html-mind-map is a skill for Claude Code from f-labs-io/agent-html-skills. It costs 107 tokens per session (2,997 once invoked), scanned A, original, MIT.

An interactive web-based mind map for arranging ideas as connected branches. It can capture brainstorms, knowledge structures, debugging possibilities, or other nested information and send the result back to the agent.

In plain words
What is it for?
Brainstorming, mapping a subject, organizing nested concepts, and exploring possible causes during debugging.
Why use it?
It makes tree-shaped thinking visible and editable instead of leaving ideas in a flat text conversation. Users can rearrange the structure before continuing.

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

html-mind-map 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 1mo 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 — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HTML Mind Map & Concept Map

Some thinking is tree-shaped or graph-shaped: brainstorming variations of an idea, mapping a knowledge domain, working through "what if X is the cause" debugging trees, or organizing nested concepts. A mind map externalizes that structure so the user can see it, rearrange it, and hand it back to the agent for the next step.

Pre-flight — run BEFORE writing the artifact

Invoke html-skills:html-skills-listen (Skill tool) first; it is idempotent. If it returns a URL, inject it verbatim as window.__CLAUDE_SUBMIT_URL__ in the HTML you are about to write, ?t= query string included (a local, single-session loopback handshake — not a credential). If it reported web/sandbox mode, leave that line out; submitToClaude then falls back to clipboard mode.

When to use this skill

  • "Brainstorm / map out / explore X"
  • "What are all the possibilities for Y"
  • "Help me think through the causes of Z"
  • "Organize these ideas / concepts / hypotheses"
  • "Build me a concept map for X"
  • Any explanation that branches recursively

Output requirements

Nodes draggable. New nodes addable inline. Connections between nodes (most often a tree, sometimes a graph). Always include one Submit button that sends the map back as a structured tree in the standard envelope.

The map starts populated with whatever the user provided as starting nodes; the user expands from there.

Boundary: this skill captures and rearranges the user's ideas as an editable tree. When the user wants Claude to generate N distinct alternatives to compare, use html-brainstorm-grid; for a written plan, html-spec-planning.

Core structure

  1. Canvas — the main interactive area where nodes live
  2. Root / starting node — central, larger, anchored
  3. Branches — child nodes radiating outward (or hanging downward)
  4. Connections — lines (sometimes labeled) showing parent-child or relational links
  5. Toolbar — add node, delete, reset
  6. Submit — one button that sends the tree back

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.
