What it does
SQL is an agent skill from sendou-ink/sendou.ink. Help write, debug, and explore SQLite database queries using Kysely. Use when writing repository code, exploring data, debugging query issues, or understanding the database schema.
Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering SQL, Database schema design and Debugging. It works with SQL and SQLite. The repository describes itself as: Competitive Splatoon Platform. The licence is AGPL-3.0.
When your agent uses it
- Writing repository code
- Debugging query issues
- Understanding the database schema
Example prompts
- “/sql”
What it can do on your machine
Read from SKILL.md and the folder at commit 5730769. 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
Shell commands in SKILL.md call:
sqlite3
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
SQL loads about 423 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 148 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.
SKILL.md

SQL Database Helper
Databases
| File | Purpose | When to use |
|---|---|---|
db.sqlite3 | Development database | Writing/testing new features, running the dev server |
db-prod.sqlite3 | Copy of production database | Exploring real data, investigating bugs, verifying assumptions about data shape |
db-test.sqlite3 | Unit test database (blank + migrations, created automatically by test runs) | Unit tests only |
db-prod.sqlite3 can be modified if the task requires it. Never modify db-copy.sqlite3 — it is the untouched backup.
Schema
All table definitions live in app/db/tables.ts. Read this file first to understand available tables, columns, and their types. Key conventions:
- Every table has a numeric
idprimary key (typenumber) - Booleans are stored as
0/1(typeDBBoolean)
Exploring data
When the user needs to explore or query existing data, use sqlite3 CLI commands against the appropriate database.
Important: Always quote table and column names with double quotes ("TableName", "columnName") because the schema uses camelCase naming and some names are reserved SQL keywords.
# Explore production data
sqlite3 db-prod.sqlite3 'SELECT * FROM "User" LIMIT 5;'
# Check schema of a table
sqlite3 db-prod.sqlite3 '.schema "User"'
# Count rows
sqlite3 db-prod.sqlite3 'SELECT COUNT(*) FROM "User";'
# Development database
sqlite3 db.sqlite3 'SELECT * FROM "User" LIMIT 5;'© sendou-ink, AGPL-3.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Questions about SQL
What does SQL do?
Help write, debug, and explore SQLite database queries using Kysely. ink. Help write, debug, and explore SQLite database queries using Kysely.
When should I use SQL?
SQL fits situations like: writing repository code; debugging query issues; understanding the database schema.
How do I install SQL in Claude Code?
Run `npx skills add sendou-ink/sendou.ink --skill sql -a claude-code`. Or copy the skill folder (.claude/skills/sql in sendou-ink/sendou.ink) into .claude/skills/sql in your project. Claude Code loads it when a task matches its description.
How do I install SQL in Codex?
Run `npx skills add sendou-ink/sendou.ink --skill sql -a codex`. Or copy the skill folder (.claude/skills/sql in sendou-ink/sendou.ink) into .agents/skills/sql in your project. Codex loads it when a task matches its description.
Can I use SQL 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 sendou-ink/sendou.ink --skill sql -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sql, .gemini/skills/sql, .github/skills/sql and .opencode/skills/sql in your project.
What does SQL need to run?
Going by SKILL.md and its folder, SQL needs the command-line tools its instructions call (sqlite3).
Does SQL 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 SQL safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does SQL use?
SQL is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does SQL use?
About 423 tokens (SKILL.md is roughly 1.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to SQL?
Skills that share tags, products or a category with SQL: Golang Database (unxed/f4, 240 stars), Cursor BYOK Database Schema (leookun/cursor-byok, 3.2k stars), SQL Expert (aiskillstore/marketplace, 430 stars) and SQL Toolkit (LeoYeAI/openclaw-master-skills, 2.2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains SQL?
sendou-ink (a GitHub organization) maintains it in sendou-ink/sendou.ink, which has 297 GitHub stars. The repository holds 7 skills in this directory. The repository was last updated on October 7, 2026.
Source: sendou-ink/sendou.ink on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
