architecture-paradigm-microkernel

architecture-paradigm-microkernel is a skill for Claude Code from athola/claude-night-market. It costs 32 tokens per session (908 once invoked), scanned A, original, MIT.

A software design approach with a small, stable core and optional plugins that add features. A plugin is an extension that follows the core system's rules.

In plain words
What is it for?
Use it to plan plugin systems for platforms, development tools, data pipelines, and marketplaces, including plugin contracts, loading, permissions, and isolation.
Why use it?
It keeps optional features and third-party code separate from the core. This allows extensions to change quickly while the main system remains stable.

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

architecture-paradigm-microkernel 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 7d 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.

The Microkernel (Plugin) Architecture Paradigm

When To Use

  • Building extensible systems with plugin architectures
  • Products requiring customer-specific customizations

When NOT To Use

  • Monolithic applications without plugin extensibility needs
  • Systems where all features are core and tightly coupled by design

When to Employ This Paradigm

  • When building platforms, Integrated Development Environments (IDEs), data ingestion pipelines, or marketplaces where third parties need to extend core functionality.
  • When the core system requires extreme stability, while extensions and features must evolve and change rapidly.
  • When isolating optional dependencies and sandboxing untrusted code provided by plugins is critical.

Adoption Steps

  1. Define Core Services: Clearly delineate the minimal responsibilities of the microkernel, such as scheduling, component lifecycle management, core domain primitives, and messaging.
  2. Specify the Plugin Contract: Design and document the formal contract for all plugins, including registration procedures, capability descriptors, lifecycle hooks (e.g., start, stop), and the permission model.
  3. Build the Extension Loader and Sandbox: Implement the mechanisms for loading extensions, performing version compatibility checks, negotiating capabilities, and isolating plugins to prevent failures from cascading.
  4. Provide a Software Development Kit (SDK): To facilitate plugin development, provide an SDK with project templates, testing harnesses, and compatibility-checking tools.
  5. Govern the Release Process: Maintain a clear compatibility matrix between core and plugin versions. Implement an automated regression test suite that validates core functionality against a variety of plugins.

Key Deliverables

  • An Architecture Decision Record (ADR) describing the division of responsibilities between the core and plugins, along with the governance model for plugin development and certification.
  • Formal documentation for the security and permission model, detailing what capabilities are available to plugins.
  • An automated plugin validation pipeline that performs linting, runs tests, and executes the plugin within a sandbox environment.
