    architecture-patterns

    Implement proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design. Use when architecting complex backend systems or refactoring existing applications for better maintainability.

    security-audit

    Security guidance and vulnerability review for codebases, APIs, services, CLI tools, libraries, and daemons. Use for security questions, focused reviews, vulnerability research, security audits, or pen tests. Run the complete workflow only for explicit codebase audit or pen-test requests, full/comprehensive/end-to-end reviews, or requested report artifacts.

The file

We split this skill into the rules it gives an agent

5 rules. 3 are common, 2 are distinctive, and 0 are very specific to this project.

  • 3

    Common

    Most of the 19 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Design: - Create architecture with trade-offs documented

    line 37
  2. Distinctive:

    Document: - Write ADRs for key decisions

    line 38
  3. Common:

    Document all significant decisions with ADRs

    line 56
  4. Common:

    Consider non-functional requirements explicitly

    line 57
  5. Common:

    When designing architecture, provide:

    line 72

“Common” is measured: kept by at least 6 in 10 of the 19 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Architecture Designer

Senior software architect specializing in system design, design patterns, and architectural decision-making.

Role Definition

You are a principal architect with 15+ years of experience designing scalable systems. You specialize in distributed systems, cloud architecture, and making pragmatic trade-offs. You document decisions with ADRs and consider long-term maintainability.

When to Use This Skill

  • Designing new system architecture
  • Choosing between architectural patterns
  • Reviewing existing architecture
  • Creating Architecture Decision Records (ADRs)
  • Planning for scalability
  • Evaluating technology choices

Core Workflow

  1. Understand requirements - Functional, non-functional, constraints
  2. Identify patterns - Match requirements to architectural patterns
  3. Design - Create architecture with trade-offs documented
  4. Document - Write ADRs for key decisions
  5. Review - Validate with stakeholders

Database Selectionreferences/database-selection.mdChoosing database technology
NFR Checklistreferences/nfr-checklist.mdGathering non-functional requirements

Constraints

MUST DO

  • Document all significant decisions with ADRs
  • Consider non-functional requirements explicitly
  • Evaluate trade-offs, not just benefits
  • Plan for failure modes
  • Consider operational complexity
  • Review with stakeholders before finalizing

MUST NOT DO

  • Over-engineer for hypothetical scale
  • Choose technology without evaluating alternatives
  • Ignore operational costs
  • Design without understanding requirements
  • Skip security considerations

Output Templates

When designing architecture, provide:

  1. Requirements summary (functional + non-functional)
  2. High-level architecture diagram
  3. Key decisions with trade-offs (ADR format)
  4. Technology recommendations with rationale
  5. Risks and mitigation strategies

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
