Plugin features

The plugin combines language-server feedback with CLI commands:

Language server: starts automatically for .sql files. When Claude writes or edits SQL, the server feeds back syntax errors, unknown tables/columns, and function typos. These diagnostics are available to Claude while it edits the file.

CLI skills: Claude can run syntaqlite fmt, syntaqlite analyze, and syntaqlite parse directly when you ask it to format a query, check a file, or inspect a parse tree.

Try it out

Open a project with .sql files and ask Claude to edit one. If the SQL has an error (say a misspelled column name), Claude will notice the diagnostic from the language server and fix it in the same edit.

You can also ask Claude to format or validate explicitly:

Format all the SQL files in src/

Check query.sql for errors against schema.sql

Add schema validation

Without a schema, the language server validates against an empty catalog: it catches syntax errors and bad function calls, but not unknown tables or columns. To enable full validation, set up a schema file. See the project setup guide for instructions.

Once configured, when Claude writes SELECT nme FROM users, the language server flags nme as unknown and suggests name. Claude sees this and corrects it automatically.
