About this skill
Data-Intensive Design Rules is a skill in ciembor/agent-rules-books (2.9k stars). Its SKILL.md is about 206 tokens, with 3 other files in the folder. Licence: MIT.
What it can do on your machine
Read from SKILL.md and the folder at commit 893a88a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Data-Intensive Design Rules loads about 206 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 57 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

Questions about Data-Intensive Design Rules
How do I install Data-Intensive Design Rules in Claude Code?
Run `npx skills add ciembor/agent-rules-books --skill designing-data-intensive-applications -a claude-code`. Or copy the skill folder (designing-data-intensive-applications in ciembor/agent-rules-books) into .claude/skills/designing-data-intensive-applications in your project. Claude Code loads it when a task matches its description.
How do I install Data-Intensive Design Rules in Codex?
Run `npx skills add ciembor/agent-rules-books --skill designing-data-intensive-applications -a codex`. Or copy the skill folder (designing-data-intensive-applications in ciembor/agent-rules-books) into .agents/skills/designing-data-intensive-applications in your project. Codex loads it when a task matches its description.
Can I use Data-Intensive Design Rules in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ciembor/agent-rules-books --skill designing-data-intensive-applications -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/designing-data-intensive-applications, .gemini/skills/designing-data-intensive-applications, .github/skills/designing-data-intensive-applications and .opencode/skills/designing-data-intensive-applications in your project.
What does Data-Intensive Design Rules need to run?
SKILL.md names no scripts, command-line tools or credentials: Data-Intensive Design Rules is instructions for the agent only.
Does Data-Intensive Design Rules access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Data-Intensive Design Rules safe to install?
