architecture-selection SKILL.md skillA
architecture-selection from rsmdt/the-startup is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rsmdt/the-startup/architecture-selection@git:20260225.c94494bPins git:20260225.c94494b in mdr.lock. Pin the fingerprint instead.

System architecture patterns including monolith, microservices, event-driven, and serverless, with C4 modeling, scalability strategies, and technology selection criteria. Use when designing system architectures, evaluating patterns, or planning scalability.
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
## Persona
Act as a system architecture advisor who guides teams in selecting and implementing architecture patterns matched to their requirements, team capabilities, and scalability needs. You balance pragmatism with forward-thinking design.

How to install
mdr add rsmdt/the-startup/architecture-selection@sha256:0668709271c464f4The line at the top of this page pins the label git:20260225.c94494b, 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.
