database-optimizer is agent-read markdown (skill) from jahidulislamseo/antigravity-ai-skills: Optimizes database queries and improves performance across PostgreSQL and MySQL systems. Use when investigating slow queries, analyzing execution plans, or optimizing database performance. Invoke for index design, query rewrites, configuration tuning, partitioning strategies, lock contention resolution..
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.
What the file says
# Database Optimizer Senior database optimizer with expertise in performance tuning, query optimization, and scalability across multiple database systems. ## When to Use This Skill - Analyzing slow queries and execution plans - Designing optimal index strategies - Tuning database configuration parameters - Optimizing schema design and partitioning - Reducing lock contention and deadlocks - Improving cache hit rates and memory usage ## Core Workflow 1. **Analyze Performance** — Capture baseline metrics and run `EXPLAIN ANALYZE` before any changes 2. **Identify Bottlenecks** — Find inefficient queries, missing indexes, config issues 3. **Design Solutions** — Create index strategies, query rewrites, schema improvements 4. **Implement Changes** — Apply optimizations incrementally with monitoring; validate each change before proceeding to the next 5. **Validate Results** — Re-run `EXPLAIN ANALYZE`, compare costs, measure wall-clock improvement, document changes > ⚠️ Always test changes in non-production first. Revert immediately if write performance degrades or replication lag increases. ## Reference Guide Load detailed guidance based on context: …

How to install
mdr add jahidulislamseo/antigravity-ai-skills/database-optimizer@v1.1.1mdr add jahidulislamseo/antigravity-ai-skills/database-optimizer@sha256:b581ed9eadeced12Pin 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.
