architect

architect is a skill for Claude Code, Codex from tmcfarlane/oh-my-cursor. It costs 10 tokens per session (4,693 once invoked), scanned A, original, MIT.

A guide for designing software architecture and making high-level technical decisions. Architecture describes how a system is divided, how its parts interact, and how it can change over time.

In plain words
What is it for?
Use it to design new systems, define interfaces and system boundaries, compare technology or pattern choices, and plan major refactors.
Why use it?
It helps teams make system-wide choices deliberately when a change affects multiple parts of a product or has long-term consequences. It separates those decisions from short-term implementation planning.

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

architect 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.

Architecture Design

Design system architecture and make strategic technical decisions.

Core Principle

Good architecture enables change while maintaining simplicity.

Name

han-core:architect - Design system architecture and high-level technical strategy

Synopsis

/architect [arguments]

Architecture vs Planning

Architecture Design (this skill):

  • Strategic: "How should the system be structured?"
  • Component interactions and boundaries
  • Technology and pattern choices
  • Long-term implications
  • System-level decisions

Technical Planning:

  • Tactical: "How do I implement feature X?"
  • Specific implementation tasks
  • Execution details
  • Short-term focus

Use /architect when:

  • Designing new systems or subsystems
  • Significant system change (new subsystem, major refactor)
  • Affects multiple components or teams
  • Major refactors affecting multiple components
  • Technology selection decisions
  • Defining system boundaries and interfaces
  • Long-term technical strategy needed
  • Need to evaluate multiple approaches
  • Decisions have broad impact

Use /plan when:

  • Implementing within existing architecture
  • Implementing specific feature within existing architecture
  • Tactical execution planning
  • Breaking down known work
  • Architecture is already decided
  • Task sequencing and execution

Architecture Process

1. Understand Context

Business context:

  • What problem are we solving?
  • Who are the users?
  • What are the business goals?
  • What are the success metrics?

Technical context:

  • What exists today?
  • What constraints exist?
  • What must we integrate with?
  • What scale must we support?

Team context:

  • What's our expertise?
  • What can we maintain?
  • What's our velocity?

2. Gather Requirements

Functional requirements:

  • What must the system do?
  • What are the features?
  • What are the user scenarios?

Non-functional requirements:

  • Performance: Response time, throughput
  • Scalability: Expected load, growth
  • Availability: Uptime requirements
  • Security: Compliance, data protection
  • Maintainability: Team size, skills
  • Cost: Budget constraints

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.

architect is a skill published in the GitHub repository tmcfarlane/oh-my-cursor (108 stars, last pushed 2mo ago), licensed MIT. It adds 10 tokens to every session and 4,693 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.
