database-postgresql is agent-read markdown (skill) from d-padmanabhan/agent-engineering-handbook: PostgreSQL database design patterns, naming conventions, schema design, migrations, performance optimization, and security best practices. Use when designing database schemas, writing migrations, optimizing queries, or working with PostgreSQL-specific features like JSONB, full-text search, or RLS..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add d-padmanabhan/agent-engineering-handbook/database-postgresql@git:20260207.963c258
Exact content
mdr add d-padmanabhan/agent-engineering-handbook/database-postgresql@sha256:bb0749e31aaacf79

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
