postgresql is agent-read markdown (skill) from jnpiyush/agentx: Develop PostgreSQL databases with JSONB, arrays, full-text search, and performance optimization. Use when writing PostgreSQL queries, using JSONB operations, implementing full-text search, optimizing query performance with indexes, or configuring row-level security..
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.
