MCP App StoreMCP App StoreProvides a clear, opinionated set of SQL formatting and query-saving conventions for agents that generate or demonstrate SQL. It standardises casing, comma placement, CTE layout, WHERE/JOIN styles, and a test-driven CTE pattern so SQL examples are consistent and easier to read and validate.
Use when the agent is asked to write, demonstrate, or save SQL queries (e.g. "write an SQL query", "show a query example"). Also apply before presenting SQL code in answers so examples follow the repository's conventions.
test CTE. The SKILL.md includes examples for SELECT, JOIN, WHERE, and full example queries.Best applied by language models or agents that generate code examples or run SQL-aware workflows (Claude-style assistants, code-focused agents, or any agent that formats SQL for humans).
A Japanese-language SQL formatting style guide from a dotfiles repo.

No scripts included — purely a markdown rule set. Niche utility limited to Japanese-speaking PostgreSQL users.
No scripts to execute. Pure markdown skill with formatting rules. No security concerns whatsoever. Architecture is flat — single SKILL.md with no scripts/ or references/ directories. Useful as a personal style guide but very niche.
