db-optimization skillA

db-optimization is agent-read markdown (skill) from jdanigo/hydraia: Use when the bottleneck is database-shaped — slow queries, lock timeouts, connection exhaustion, N+1 patterns, index questions, schema migrations on hot tables. Evidence-first DB playbook for PostgreSQL, MySQL/MariaDB, MongoDB, and Redis backing the db-performance-tuner agent..

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 jdanigo/hydraia/db-optimization@git:20260703.44486a5
Exact content
mdr add jdanigo/hydraia/db-optimization@sha256:d098b208e00145a4

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.
