designing-data-intensive-applications SKILL.md skillA
designing-data-intensive-applications from ciembor/agent-rules-books is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Apply Martin Kleppmann-inspired data-system rules when designing reliability, scalability, consistency, replication, transactions, streams, or schema evolution.
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
# Designing Data-Intensive Applications Skill Use this skill when a task involves data ownership, consistency semantics, event flows, replication, partitioning, transactions, streams, batch processing, fault tolerance, or schema evolution. Before making design or code decisions, read and apply [designing-data-intensive-applications.mini.md](designing-data-intensive-applications.mini.md). Use [designing-data-intensive-applications.md](designing-data-intensive-applications.md) only as a deeper reference when the mini rules are not enough for the current data-system tradeoff.

How to install
mdr add ciembor/agent-rules-books/designing-data-intensive-applications@sha256:7d456399437f9840The line at the top of this page pins the label git:20260909.802595f, 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.
