set-up-database SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
set-up-database from velimirmueller/claude-development-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when a backend needs Postgres, or its schema changes by hand or by `db push` — sets up local Postgres via compose, the ORM or sqlc, pooling, service-layer transactions, versioned reviewed migrations, seed data, and a migration-safety gate.
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
# Set Up Database
Rules and per-track seam code: [database-patterns.md](database-patterns.md). Migration workflow, safety checklist, per-tool recipes: [migration-patterns.md](migration-patterns.md). Layer paths: [service-layout.md](../_shared/service-layout.md). Config: [config.md](../_shared/config.md). Versions: [stack-versions.md](../_shared/stack-versions.md).
Postgres only. Schema changes are versioned SQL files in git, reviewed in the PR, applied forward-only to shared environments.

How to install
mdr add velimirmueller/claude-development-skills/set-up-database@sha256:c44f1d6b6df8e2d3The line at the top of this page pins the label git:20261009.e2b6168, 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.
