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 | $0.00000 | $0.00300 |
| Opus 5 | $0.00000 | $0.00150 |
| Sonnet 5 | $0.00000 | $0.00060 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
design 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 9d 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
/design
Model a system's architecture as a C4 diagram.
When to use
Describe a system, paste a list of services, share a README, or just say what you're building. The agent will extract the key elements and render the right C4 level for your audience.
What it produces
- Context diagram (for business/executive audiences)
- Container diagram (for architects and engineers)
- Component diagram (for development teams)
- Interactive SVG with clickable drill-down between levels
How to invoke
/design
Then describe your system in natural language. Examples:
/design
Our credit card platform has a React portal, a .NET API, Azure SQL,
and integrates with Visa for payment processing and Azure AD for auth.
/design context
Show how our SaaS platform fits into the wider business ecosystem.
/design container
Zoom into the payment service — it has a REST API, a background worker,
a Postgres database, and publishes to a Kafka topic.
Levels
Append a level hint to control zoom depth:
/design context— system boundary, users, external systems/design container— deployable units inside the system/design component— structural building blocks inside one container
Default (no level): agent starts at Context and offers to drill down.

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.

design is a command published in the GitHub repository vijayjoshi24/ea-agent-skills (5 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 300 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
