visualize

visualize is a command for Claude Code from athola/claude-night-market. It costs 16 tokens per session (479 once invoked), scanned A, original, MIT.

A command that creates Mermaid diagrams, which are text-defined visual charts, for a codebase's architecture, data flow, dependencies, workflows, or classes.

In plain words
What is it for?
Use it to document system structure, trace dependencies and data movement, or create diagrams for onboarding and code reviews.
Why use it?
It turns difficult-to-read relationships between modules and files into diagrams that are easier to inspect and explain.

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

visualize 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 6d 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.

What it actually says

Visualize Codebase

Generate visual diagrams of codebase structure using Mermaid Chart MCP rendering.

Arguments

  • type - Diagram type: architecture, data-flow, dependency, workflow, or class (required)
  • scope - Directory path to limit analysis (optional, defaults to project root)

Usage

/visualize architecture
/visualize data-flow plugins/sanctum
/visualize dependency --depth 2
/visualize workflow .github/workflows
/visualize class plugins/sanctum/scripts

Diagram Types

Type Skill Mermaid Format
architecture cartograph:architecture-diagram flowchart TD
data-flow cartograph:data-flow sequenceDiagram
dependency cartograph:dependency-graph flowchart LR
workflow cartograph:workflow-diagram flowchart TD/LR
class cartograph:class-diagram classDiagram
call-chain cartograph:call-chain flowchart TD
communities cartograph:code-communities flowchart TD

Workflow

  1. Parse the diagram type from arguments
  2. Invoke the matching skill:
    • architecture invokes Skill(cartograph:architecture-diagram)
    • data-flow invokes Skill(cartograph:data-flow)
    • dependency invokes Skill(cartograph:dependency-graph)
    • workflow invokes Skill(cartograph:workflow-diagram)
    • class invokes Skill(cartograph:class-diagram)
    • call-chain invokes Skill(cartograph:call-chain)
    • communities invokes Skill(cartograph:code-communities)
  3. Pass scope argument to the skill
  4. Skill handles exploration, Mermaid generation, and MCP rendering

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.
