Design and review high-performance YugabyteDB YSQL schemas. Covers hash vs range sharding, write hotspots on sequential columns, partial indexes for nullable or skewed columns, low-cardinality indexes, covering indexes, primary keys, foreign key indexes, and redundant index cleanup. Includes read-only scripts and an offline analyzer that review an existing database from its catalog, pg_stats, pg_stat_statements or statements.json. Use this skill when the user asks how to design a YugabyteDB…
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
# YugabyteDB Schema Design Best Practices This skill covers **how to design schemas well** for YugabyteDB: the design patterns that make a schema performant in a distributed SQL environment. ## Two Modes - **Design mode**: the user is designing or changing tables and indexes. Use the reference files below and the golden rules. - **Review mode**: the user wants an *existing* database reviewed: live (you may connect) or offline (they have, or can produce, a schema dump / stats export / statements file). Read `references/review-mode.md` first. It covers the bundle, safety rules, the scripts, how to triage the analyzer's findings, and the rollout runbook. Never run DDL or `ANALYZE` against the user's database. Changes go into `changes.sql` (phased, with `rollback.sql`), rendered from the triaged `findings.json` so the SQL always matches the report. ## Core Concepts (Read First) YugabyteDB is an index-organized, distributed SQL database. Every design decision flows from three foundational facts: 1. **The primary key IS the table.** Rows are stored sorted by PK. No PK = system assigns `ybrowid` (hidden, hash-sharded). …

How to install
mdr add srinivasa-vasu/agent-skills/yugabytedb-schema-design@sha256:c91810dd9a2f6b41The line at the top of this page pins the label git:20261015.a2fe562, 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.
