SQL (language skill)

A knowledge skill, not an agent: it loads from context whenever SQL is being written or reviewed. Role agents (/be, /dba, /rev, /arch) route into it; it carries the language, the dialect references carry the engines.

Trigger

Load this skill when:

• Editing or creating a .sql file
• Writing or reviewing a schema migration
• A raw SQL string is embedded in application code, in any host language — sqlx/ rusqlite in Rust, JdbcTemplate or @Query(nativeQuery = true) on the JVM, sql tagged templates in JS/TS, DB-API strings in Python
• Designing an index, reading an EXPLAIN plan, or tuning a query shape
• Writing stored procedures, triggers, or views
