aget: Skill for Claude Code

.claude/skills/aget-design-architecture/SKILL.md

aget-design-architecture is a skill for Claude Code from aget-framework/aget. It costs 12 tokens per session (582 once invoked), scanned A, original, Apache-2.0.

A guide for planning a software system's structure, including its parts, boundaries, connections, and design patterns.

In plain words
What is it for?
Use it to define components, interfaces, dependencies, communication methods, and qualities such as scalability, reliability, and security.
Why use it?
It turns requirements and constraints into an architecture that can be reviewed before implementation begins.

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

aget-design-architecture 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.

aget-design-architecture

Design system architecture including components, relationships, and patterns. Addresses quality attributes and produces architectural artifacts.

Instructions

When this skill is invoked:

  1. Understand Requirements

    • Gather functional requirements
    • Identify quality attributes (scalability, reliability, security, etc.)
    • Note constraints (technology, budget, timeline)
  2. Decompose the System

    • Identify logical components
    • Define responsibilities (single responsibility)
    • Establish boundaries
  3. Select Patterns

    • Choose appropriate architectural patterns:
      • Layered, Microservices, Event-Driven, etc.
    • Match patterns to requirements and constraints
  4. Define Relationships

    • Document interfaces between components
    • Specify communication protocols
    • Map dependencies
  5. Address Quality Attributes

    • Scalability: How system grows
    • Reliability: How system handles failure
    • Security: How system protects assets

Output Format

## Architecture Design: [System Name]

### Overview

[2-3 sentence description of the architecture]

### Components

| Component | Responsibility | Interface |
|-----------|---------------|-----------|
| [Name] | [What it does] | [API/Events/etc.] |

### Architecture Diagram

┌─────────────┐ ┌─────────────┐ │ Component A │────▶│ Component B │ └─────────────┘ └─────────────┘ │ ▼ ┌─────────────┐ │ Component C │ └─────────────┘


### Patterns Applied

| Pattern | Rationale |
|---------|-----------|
| [Pattern] | [Why chosen] |

### Quality Attributes

| Attribute | Approach |
|-----------|----------|
| Scalability | [How addressed] |
| Reliability | [How addressed] |
| Security | [How addressed] |

### Dependencies

A → B (sync API) B → C (async events)


### Risks & Trade-offs

- [Trade-off 1]: [What was traded for what]

Constraints

  • C1: NEVER propose architecture without understanding requirements — architecture serves requirements
  • C2: NEVER introduce unnecessary complexity — simplest solution meeting requirements preferred
  • C3: NEVER ignore non-functional requirements — quality attributes are architectural drivers

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.

aget-design-architecture is a skill published in the GitHub repository aget-framework/aget (11 stars, last pushed today), licensed Apache-2.0. It adds 12 tokens to every session and 582 once invoked, about $0.0001 per session on Opus 5. 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.
