Procedures for database schema integrity, idempotent migrations, backup/restore execution, and dependency maintenance.
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
# Repository Maintenance Skill This skill provides procedures for maintaining database integrity, executing database backups, applying schema migrations, and managing dependencies across repositories. --- ## 1. Local Branch-First Development > [!IMPORTANT] > **CREATE A LOCAL BRANCH FIRST**: Always start by creating a dedicated local branch from `main`: > ```bash > git switch -c <developer-or-agent>/main/<feature-name> > ``` > Never apply maintenance or schema changes directly on `main`. --- ## 2. Database Schema Integrity & Migrations > [!CAUTION] > **CRITICAL RULE**: Never execute destructive SQL statements (`DROP TABLE`, `TRUNCATE`) in production environments. ### Migration Rules - All migrations MUST be located in a versioned migrations directory (e.g. `db/migrations/` or `migrations/`) using timestamped or numbered files (`NNNNNN_<name>.up.sql` and `NNNNNN_<name>.down.sql`). - All SQL statements MUST be idempotent: - `CREATE TABLE IF NOT EXISTS ...` - `CREATE INDEX IF NOT EXISTS ...` - `ALTER TABLE ... ADD COLUMN IF NOT EXISTS ...` --- ## 3. Backup & Disaster Recovery Runbook PostgreSQL database dumps should be automated with SHA-256 integrity verification: …

How to install
mdr add mishrashardendu22/agent-skills/repository-maintenance@sha256:8e7c3bd83edd6b7bThe line at the top of this page pins the label git:20260914.e06e21c, 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.
