Data-Intensive Applications
Design reliable, scalable data systems with proven patterns for consistency, replication, and streams.
Installation
- Make sure Claude is on your device and in your terminal.
Skills load from
~/.claude/skills/when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then runclaudein any terminal to verify.One-time setupnpm i -g @anthropic-ai/claude-codeAlready have it? Skip ahead.
- Paste into Claude Code or into your terminal.
This copies the whole skill folder into
~/.claude/skills/designing-data-intensive-applications-ciembor/— the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.Faster alternative (instruction-only skills)
Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.
Quick install (SKILL.md only)Sign up to copy - Restart Claude Code.
Quit and reopen Claude Code (or any other agent that loads from
~/.claude/skills/). New skills are picked up on startup. - Just ask Claude.
Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

When Claude uses it
Apply Martin Kleppmann-inspired data-system rules when designing reliability, scalability, consistency, replication, transactions, streams, or schema evolution.
What this skill does
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. Use designing-data-intensive-applications.md only as a deeper reference when the mini rules are not enough for the current data-system tradeoff.
