skill-visualizer

skill-visualizer is a skill for Claude Code from mhylle/claude-skills-collection. It costs 67 tokens per session (661 once invoked), scanned A, original, MIT.

A tool for generating interactive web pages that show skills, code structure, or dependencies as diagrams.

In plain words
What is it for?
It helps create maps of available skills, visual overviews of a codebase, and dependency graphs with expandable nodes and hover details.
Why use it?
It makes large collections and relationships easier to explore than a plain folder or text list.

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

skill-visualizer 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/visualize.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Skill Visualizer

Generate interactive HTML visualizations for exploring skills, codebase structure, and dependencies.

Overview

This skill creates browser-viewable HTML files with interactive diagrams. It supports multiple visualization types and outputs self-contained HTML files that open directly in any browser.

Arguments

  • $0: Output type - skills, codebase, or deps (default: skills)

Examples:

  • /skill-visualizer - Generate skills collection map
  • /skill-visualizer skills - Generate skills collection map
  • /skill-visualizer codebase - Generate codebase structure visualization
  • /skill-visualizer deps - Generate skill dependency graph

Visualization Types

Skills Map (skills)

Generates an interactive force-directed graph of all skills showing:

  • Skill nodes with name and type indicator
  • Color coding by skill type:
    • Green: Orchestrators (context: fork)
    • Blue: Read-only (allowed-tools restrictions)
    • Orange: Hybrid (standard skills)
  • Hover tooltips with skill descriptions
  • Drag to reposition nodes

Codebase Structure (codebase)

Generates a treemap visualization of the project structure:

  • Directory hierarchy with expandable nodes
  • File type distribution by color
  • Size indicators for each file/directory

Dependency Graph (deps)

Generates a directed graph showing skill dependencies:

  • Which skills invoke other skills
  • Integration points between skills
  • Visual workflow representation

Usage

  1. Invoke the skill with desired output type
  2. The skill runs Python scripts to analyze the codebase
  3. Generates self-contained HTML with embedded CSS/JS
  4. Opens in default browser automatically
# Run directly
python ~/.claude/skills/skill-visualizer/scripts/visualize.py skills

# Output location
docs/visualizations/skills-map-YYYY-MM-DD.html

Output

All visualizations are saved to docs/visualizations/:

  • skills-map-YYYY-MM-DD.html
  • codebase-structure-YYYY-MM-DD.html
  • skill-deps-YYYY-MM-DD.html

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.
