## What it does and how to use it

A **skill** that teaches Claude Code to do databases tasks well. It is packaged knowledge the model uses whenever it is relevant.

1. Install the skill (command above).
2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
3. No commands to memorize: you talk in plain language and the skill does the rest.

## Install (Claude Code)

```bash
mkdir -p .claude/skills/data-pagination && curl -fsSL https://doutorai.pt/data/lib/skills__data-pagination.md -o .claude/skills/data-pagination/SKILL.md
```

Paste this command into the terminal, in your project folder, and the component installs automatically.

## Use Cursor-Based Pagination Instead of OFFSET

OFFSET-based pagination scans all skipped rows, getting slower on deeper pages. Cursor pagination is O(1).

**Incorrect (OFFSET pagination):**

```sql
-- Page 1: scans 20 rows
select * from products order by id limit 20 offset 0;

-- Page 100: scans 2000 rows to skip 1980
select * from products order by id limit 20 offset 1980;

-- Page 100
