design

design is a command for coding agents from nguyenthienthanh/aura-frog. It costs 0 tokens per session (252 once invoked), scanned A, original, MIT.

A set of commands for designing APIs, databases, and technical documentation before coding. An API is the defined way that software systems exchange requests and responses.

In plain words
What is it for?
Use it to design REST or GraphQL APIs, database schemas and migrations, and structured feature, API, component, or architecture documents.
Why use it?
It helps settle data structures, endpoints, errors, relationships, and documentation before implementation begins.

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.

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

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 5d 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 Commands

Design APIs, databases, and documentation before coding.

Category: Design Scope: Session


/design api

Design API endpoints with OpenAPI spec generation. Detects REST vs GraphQL from project. Generates endpoint definitions, request/response schemas, error handling patterns, versioning strategy, and OpenAPI 3.0 YAML.

Usage: /design api "User management CRUD with roles", /design api --graphql


/design db

Design database schema with ERD and migration scripts. Generates entity definitions, relationships, indexes, constraints, and migration files for the detected ORM (Prisma/TypeORM/Eloquent/SQLAlchemy/GORM).

Usage: /design db "E-commerce: users, products, orders, payments"


/design doc

Generate documentation: feature specs, API docs, component docs, architecture docs. Produces structured markdown with sections appropriate to the doc type.

Usage: /design doc "User authentication feature", /design doc --type api


  • Skills: api-designer, documentation
  • Agents: architect (API + DB design), lead (documentation)

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 nguyenthienthanh/aura-frog (24 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 252 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 2026-08-30.
