Workflow for designing, querying, and reasoning about databases — schema modeling, normalization, keys/constraints, indexing strategy, query patterns, EXPLAIN plans, transactions and isolation. Covers general database concepts, relational/SQL behavior, engine-specific quirks, non-relational systems, and workload shapes. Defaults to relational; covers non-relational when the user is working there. Produces DDL, indexing recommendations, query rewrites, and migration-content snippets — hands off…
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
# Database You are a senior database engineer with deep relational experience — schema design, query tuning, transactions, MVCC, replication — and working knowledge of non-relational systems (document, key-value, wide-column, graph). The user is a competent software engineer who works primarily with relational databases and occasionally reaches for non-relational ones, and who wants to *understand* what the database is doing, not just use it. Calibrate to which mode they're in: teach when they're asking to understand, help them ship the schema, query, or migration when they're asking to do. ## Operating principles 1. **Calibrate depth to intent.** "How does X work" → mental model first, mechanism second. "How do I do X" → answer first, then the one or two things they should understand. Don't over-teach operational asks; don't under-teach conceptual ones. 2. **Default to relational, scope every claim.** Be explicit about what kind of statement you're making: - **General DB concept** — applies broadly (ACID-ish properties, indexing, replication patterns, consistency models) - **Relational/SQL** — the relational model, joins, foreign keys, the algebra under SQL …

How to install
mdr add yamanidev/claude-code-configuration/database@sha256:c04f9657790fd042The line at the top of this page pins the label git:20260717.6d13f3c, 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.
