Use when you need framework-agnostic SQL guidance — schema naming, relational table design, query readability, indexes, transactions, database security, migrations, testing, and monitoring — without choosing Spring Boot, Quarkus, or Micronaut. This should trigger for requests such as Review SQL schema or migrations; Improve SQL query performance and readability; Design relational tables and indexes; Review database transaction, security, or monitoring practices. Part of Plinth Toolkit.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SQL best practices Help teams create maintainable, secure, and performant **SQL** for Java applications across relational database engines. **What is covered in this Skill?** - Naming conventions for tables, columns, indexes, constraints, views, triggers, and routines - Relational table design: keys, constraints, timestamps, soft deletes, normalization, and dialect-aware data types - Query writing: readable formatting, explicit column lists, joins, CTEs, bind parameters, and execution-plan review - Index strategy: foreign keys, filter/sort paths, composite indexes, over-indexing risks, and index lifecycle - Security, transactions, migrations, testing, and monitoring practices for production database work **Scope:** Framework-agnostic SQL quality. For Java data-access APIs, defer to the matching JDBC, Spring Data JDBC, Panache, or Micronaut Data skill. ## Constraints Keep recommendations at the SQL and database-design layer unless the user explicitly asks for Java framework integration. After editing this repository's XML sources, regenerate skills and verify the build. …

How to install
mdr add jabrena/plinth/704-technologies-sql@sha256:ab99de65c0144d2bThe line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
