Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Repository Maintenance Skill
This skill provides procedures for maintaining database integrity, executing database backups, applying schema migrations, and managing dependencies across the GitHub Backup Automation System.
1. Branch-First Development
> [!IMPORTANT] > CREATE A LOCAL BRANCH FIRST: Always start by creating a local branch from main: > ``bash > git switch -c MishraShardendu22/main/ > ` > 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). Production data has historical backup logs spanning months.
Migration Rules
- All migrations MUST be located in
backend/db/migrations/using versioned namingNNNNNN_.up.sqlandNNNNNN_.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 ...- Schema migrations are orchestrated exclusively by Go backend startup (
backend/db/migrator.go).
2. Backup & Disaster Recovery Runbook
PostgreSQL database dumps are automated with SHA-256 integrity verification:
# 1. Execute an automated database backup (stored in backups/postgres/ with 14-day retention)
make backup-db
# 2. Restore database from a backup file
make restore-db BACKUP_FILE=backups/postgres/gbm_pg_backup_YYYYMMDD_HHMMSS.sql.gz3. Dependency Management
- Go Dependencies: Managed via
go.mod. Update withgo get -uand clean withgo mod tidy. - Python Observatory: Managed via
uvinagentic-observatory/. Update withuv lock --upgradeand sync withuv sync. - Frontend Dashboard: Managed via
pnpminfrontend/. Update withpnpm update. Ensure native modules likesharpand@biomejs/biomeremain authorized infrontend/pnpm-workspace.yaml.
