AutoSkillit: Skill for Claude Code

.claude/skills/make-arch-diag/SKILL.md

make-arch-diag is a skill for Claude Code from TalonT-Org/AutoSkillit. It costs 33 tokens per session (2,236 once invoked), scanned A, original, MIT.

An architecture diagram is a visual description of a system or one of its components. This skill creates Mermaid diagrams showing structure, data movement, and sequences.

In plain words
What is it for?
Use it to diagram a selected component or system, such as authentication, APIs, databases, queues, state management, or a feature flow.
Why use it?
It gives developers a clearer way to understand how parts of a system interact before onboarding, documenting changes, or redesigning it.

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

make-arch-diag 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 7d 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.

Make-Arch-Diag: Architecture Diagram Generation

Creates comprehensive architecture diagrams for selected components or systems using mermaid syntax.

When to Use

  • Documenting a new feature or component
  • Updating architecture documentation after changes
  • Onboarding new team members
  • Explaining complex system interactions
  • Before making significant architectural changes

Critical Constraints

ALWAYS:

  • Ask user which component/system to diagram
  • Use the /mermaid skill for diagram creation
  • Include multiple views (data flow, component structure, sequence diagrams)
  • Save diagrams to temp/make-arch-diag/{component-name}/
  • Use consistent color coding across all diagrams

NEVER:

  • Create diagrams without understanding the code
  • Skip reading the actual implementation
  • Use generic placeholder names
  • Create diagrams that contradict the code

Workflow

Step 1: Component Selection

Ask the user which area they want diagrammed:

Which component or system would you like to diagram?

Examples:
- Authentication system
- Database layer
- API endpoints
- Message queue processing
- State management
- Specific feature (e.g., "user registration flow")

Please specify the component/system:

Step 2: Scope Definition

Based on user input, determine:

  • Boundaries: What's in scope vs out of scope
  • Level of Detail: High-level architecture vs detailed implementation
  • Audience: Developers, architects, stakeholders

Step 3: Code Exploration

Investigate the codebase:

  • Find entry points (main, CLI, API routes)
  • Trace execution flows
  • Identify components and their relationships
  • Map data flows
  • Document external dependencies

Step 4: Diagram Types Selection

Choose appropriate diagram types:

Component Diagram (Always include)

  • Shows major components and their relationships
  • Good for: Understanding system structure

Data Flow Diagram (Include if data transformation is central)

  • Shows how data moves through the system
  • Good for: Understanding pipelines, ETL, processing

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.
