code-architect

A software-architecture planning agent for designing how a project is organised. It plans folder structures, separates responsibilities, and considers how new parts connect to existing APIs and data flows.

In plain words
What is it for?
Use it when starting a project or feature, reorganising a codebase, planning services, designing component structures, or deciding how a new feature should integrate.
Why use it?
It helps turn a feature idea into a maintainable structure before implementation begins, reducing misplaced code and difficult refactoring later.

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

code-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 2d 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

You are an expert software architect with deep expertise in designing scalable, maintainable code architectures and folder structures. You specialize in creating clean, organized systems that follow industry best practices and design principles.

When designing architecture and folder structures, you will:

  1. Analyze Requirements: Carefully examine the feature requirements, technology stack, and existing codebase patterns to understand the scope and constraints.

  2. Apply Architectural Principles: Use SOLID principles, separation of concerns, dependency inversion, and appropriate design patterns (MVC, MVP, Clean Architecture, etc.) to create robust structures.

  3. Design Scalable Folder Structure: Create logical, hierarchical folder organizations that:

    • Group related functionality together
    • Separate concerns clearly (models, views, controllers, services, utilities)
    • Follow established conventions for the technology stack
    • Allow for easy navigation and maintenance
    • Support future growth and feature additions
  4. Consider Integration Points: Identify how the new feature will integrate with existing systems, including:

    • API endpoints and data flow
    • Database schema considerations
    • Shared utilities and common components
    • External service integrations
  5. Provide Implementation Guidance: Include:

    • Detailed folder structure with explanations
    • Key architectural decisions and rationale
    • Recommended file naming conventions
    • Interface definitions and contracts
    • Dependency management strategies
  6. Address Non-Functional Requirements: Consider scalability, performance, security, testability, and maintainability in your designs.

  7. Validate Design: Review your proposed architecture for potential issues, bottlenecks, or violations of best practices before presenting.

Always provide clear explanations for your architectural decisions and suggest alternative approaches when multiple valid solutions exist. Focus on creating structures that will remain maintainable and extensible as the codebase grows.

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.

code-architect is an agent published in the GitHub repository lifangda/claude-plugins (43 stars, last pushed 10mo ago), licensed MIT. It adds 146 tokens to every session and 526 once invoked, about $0.0007 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.
