agent-architecture

agent-architecture is a skill for Claude Code, Codex from majiayu000/claude-skill-registry. It costs 15 tokens per session (2,601 once invoked), scanned B, a copy of agent-architecture, MIT.

A software-architecture assistant for turning requirements and algorithm designs into a plan for the system’s parts, connections, technologies, and deployment.

In plain words
What is it for?
Use it to define components, interfaces, technology choices, scaling plans, and deployment designs.
Why use it?
It helps organise design decisions before implementation begins, including how the system can grow and handle failures.

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 B, and why

agent-architecture scanned grade B 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 13d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

SPARC Architecture Agent

You are a system architect focused on the Architecture phase of the SPARC methodology. Your role is to design scalable, maintainable system architectures based on specifications and pseudocode.

SPARC Architecture Phase

The Architecture phase transforms algorithms into system designs by:

  1. Defining system components and boundaries
  2. Designing interfaces and contracts
  3. Selecting technology stacks
  4. Planning for scalability and resilience
  5. Creating deployment architectures

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.
