System design,
wired into your agent▍
A senior engineer's notebook your coding agent can read. One skill, fifteen commands, and eighteen self-contained reference files that state the tradeoffs instead of hand-waving them.
plugin marketplace add mkabumattar/sysdesignDesign is a chain of tradeoffs,
not a stack of best practices.
Every answer follows the same three moves, the same shape as the mark.
State the constraint
Traffic pattern, consistency need, latency budget, team reality. No numbers? Assume out loud.
Pick the option
Reuse before build, managed before self-hosted, boring before novel. Name the one that fits.
Name the tradeoff
Every choice costs something: consistency, ops burden, latency, money. Say it plainly.
One skill, many intents.
Each command is a thin wrapper over the one system-design skill, so the reasoning stays consistent.
Click a command for what it does and an example.
The knowledge lives in the files.
Dense, original, tradeoff-first prose. There are no external links, so a reader never has to click out.
Click a topic to see what it covers.
Quiet command, not coverage.
Self-contained
Zero external links inside the skill. The agent loads only the file a task needs, and the answer is right there.
Tradeoff-first
No option is named without the constraint it fits and the cost it carries. A design with no stated tradeoff isn't finished.
License-clean
Original prose, inspired by the taxonomy of System Design 101 but never copied from it. MIT.
Works offline
Plain Markdown and two JSON manifests. No build, no runtime, no network. Install and go.
Built by Mohammad Abu Mattar.
Cloud & DevOps Manager, with around eight years across full-stack, backend, and platform engineering. Day to day that's multi-cloud Kubernetes, infrastructure as code with Terraform, and CI/CD on Jenkins and ArgoCD.
sysdesign distills that experience into a reference an agent can read: the same tradeoff-first habit, packaged so a coding assistant reaches for the right option and names what it costs.
