system-architecture from endorphin-ai/hasbrains-agent-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when designing a system, choosing an architecture pattern, making a technology decision, or doing capacity/scalability planning — BEFORE drilling into framework-specific mechanics. A lean MAP over three reference docs: pattern selection (monolith → modular monolith → microservices → event-driven → CQRS → event sourcing → hexagonal → clean → API gateway, with trade-offs), the how-to system-design workflows (system-design-interview approach, capacity planning, API design, DB schema design…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
TASKLANG
TYPE SKILL
IDENTITY "System Architecture"
> General-purpose system-design knowledge for the planning step that comes
> BEFORE technology-specific mechanics: pick the right architecture PATTERN,
> make the load-bearing TECHNOLOGY decisions, and run the system-design
> WORKFLOWS (capacity, API, schema, scalability, migration). This skill is a
> lean MAP — the substance lives in three reference docs under references/.
> Read the map, then open the one reference that matches the question.
!!! References FIRST — this SKILL.md only routes; the answers live in references/.
!!! This is technology-AGNOSTIC system design. Framework-specific mechanics —
!!! this stack's module/context boundaries, its ORM schema and migration syntax,
!!! its background-job and authorization APIs — belong to a stack-specific skill.
!!! system-architecture supports the PLANNING that precedes those mechanics.

## When to use this skill
KNOWLEDGE
USE_WHEN
- "Choosing an architecture pattern for a new system or a milestone (and weighing its trade-offs)."
- "Making a technology decision — database, cache, message queue, auth, frontend framework, cloud provider, API style."

How to install
mdr add endorphin-ai/hasbrains-agent-kit/system-architecture@sha256:bbb3332e7ffce548The line at the top of this page pins the label git:20260731.4cba6d1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
