Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned personamanagmentlayer/pcl at 79ccaa9820.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides expert guidance on system design, software architecture, and distributed systems. It covers core architectural patterns like microservices, event-driven architectures, layered architectures, and more. The skill also explains scalability strategies (horizontal vs. vertical scaling, caching, database sharding) and concepts related to distributed systems such as the CAP theorem and consensus algorithms.

When to use it

  • When designing a new software system or application architecture.
  • To understand different architectural patterns and their trade-offs.
  • For troubleshooting scalability issues in an existing system.
  • To learn about best practices for building robust distributed systems.
  • To explore design patterns like Singleton, Factory, Observer, Strategy, and Circuit Breaker.

Key capabilities

  • Architectural Patterns: Explains microservices vs monolithic architectures, event-driven architecture, CQRS/Event Sourcing, layered architecture, hexagonal architecture, and service-oriented architecture (SOA).
  • Scalability Strategies: Covers horizontal and vertical scaling, load balancing, caching layers, database sharding, and CDN usage.
  • Distributed Systems Concepts: Provides insights into the CAP theorem, consistency models, distributed consensus (Raft, Paxos), message queues, service discovery, and circuit breakers.
  • Design Patterns: Illustrates common design patterns with code examples including Singleton, Factory, Observer, Strategy, and Circuit Breaker.

Example prompts

  • "Explain the difference between microservices and a monolithic architecture."
  • "What are some strategies for scaling a database?"
  • "Can you give me an example of how to implement a circuit breaker pattern in Python?"
  • "Describe the CAP theorem and its implications for distributed systems design."

Tips & gotchas

  • The skill provides conceptual explanations and code examples. It is not intended as a substitute for practical implementation experience.
  • While it covers various patterns, understanding their applicability requires careful consideration of specific project requirements.
