Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00028 | $0.02482 |
| Opus 5 | $0.00014 | $0.01241 |
| Sonnet 5 | $0.00006 | $0.00496 |
| Haiku 4.5 | $0.00003 | $0.00248 |
Grade A, and why
diagram scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Eraser Diagram Generator
Generates professional architecture diagrams directly from code, infrastructure files, or natural language descriptions using the Eraser API.
When to Use
Activate this skill when:
- User asks to create, generate, or visualize a diagram
- User wants to document architecture from code
- User has Terraform, AWS, Azure, or infrastructure files
- User describes a system and wants it visualized
- User mentions "diagram", "architecture", "visualize", or "draw"
How It Works
- Analyze the source: Extract architecture information from code, files, or descriptions
- Generate Eraser DSL: Create Eraser DSL code that describes the diagram
- Call the Eraser API: Make an HTTP POST request to render the diagram
- Return the result: Present the image URL and editor link to the user
Diagram Types and Syntax
Eraser supports five types of diagrams, each optimized for different use cases. For detailed DSL syntax and examples, refer to the appropriate reference file:
Flow Charts
Visualize process flows, user flows, and logic flows represented as nodes, groups, and relationships. Diagrams are created using simple syntax.
Use for: Process flows, user journeys, decision trees, business process documentation
diagramType: "flowchart-diagram"
Reference: Flowchart Syntax
Entity Relationship Diagrams (ERD)
Visualize data models represented as entities, attributes, and relationships. Diagrams are created using simple syntax.
Use for: Database schema design, data modeling, understanding entity relationships, documenting data structures
diagramType: "entity-relationship-diagram"
Reference: ERD Syntax
Cloud Architecture Diagrams
Visualize cloud infrastructure represented as nodes, groups, and connections. Diagrams are created using simple syntax.
Use for: Cloud infrastructure visualization, AWS/Azure/GCP architectures, system architecture documentation, data flow visualization
What ships with it
5 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.
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.

diagram is a skill published in the GitHub repository eraserlabs/eraser-io (39 stars, last pushed 5mo ago), licensed MIT. It adds 28 tokens to every session and 2,482 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
