lmiranda 2d51df7a42 feat(marketplace): command consolidation + 8 new plugins (v8.1.0 → v9.0.0) [BREAKING]

Phase 1b: Rename all ~94 commands across 12 plugins to /<noun> <action>
sub-command pattern. Git-flow consolidated from 8→5 commands (commit
variants absorbed into --push/--merge/--sync flags). Dispatch files,
name: frontmatter, and cross-reference updates for all plugins.

Phase 2: Design documents for 8 new plugins in docs/designs/.

Phase 3: Scaffold 8 new plugins — saas-api-platform, saas-db-migrate,
saas-react-platform, saas-test-pilot, data-seed, ops-release-manager,
ops-deploy-pipeline, debug-mcp. Each with plugin.json, commands, agents,
skills, README, and claude-md-integration. Marketplace grows from 12→20.

Raw Blame History

saas-db-migrate

Database migration management for Alembic, Prisma, and raw SQL.

Overview

The saas-db-migrate plugin provides a complete database migration toolkit. It detects your migration tool, generates migration files from model diffs, validates migrations for safety before applying, plans execution with rollback strategies, and tracks migration history.

Supported Migration Tools

Alembic (Python/SQLAlchemy) - Revision-based migrations with auto-generation
Prisma (Node.js/TypeScript) - Schema-first migrations with diff-based generation
Raw SQL - Sequential numbered SQL files for any database

Supported Databases

PostgreSQL (primary, with lock analysis)
MySQL (with engine-specific considerations)
SQLite (with ALTER limitations noted)

Commands

Command	Description
`/db-migrate setup`	Setup wizard - detect tool, map configuration
`/db-migrate generate <desc>`	Generate migration from model diff or empty template
`/db-migrate validate`	Check migration safety (data loss, locks, rollback)
`/db-migrate plan`	Show execution plan with rollback strategy
`/db-migrate history`	Display migration history and current state
`/db-migrate rollback`	Generate rollback migration or plan

Agents

Agent	Model	Mode	Purpose
`migration-planner`	sonnet	default	Migration generation, planning, rollback
`migration-auditor`	haiku	plan (read-only)	Safety validation and risk assessment

Installation

This plugin is part of the Leo Claude Marketplace. It is installed automatically when the marketplace is configured.

Prerequisites

A project with an existing database and migration tool
Run /db-migrate setup before using other commands

Configuration

The /db-migrate setup command creates .db-migrate.json in your project root with detected settings. All subsequent commands read this file for tool and path configuration.

Safety Philosophy

This plugin prioritizes data safety above all else. Every migration is analyzed for:

Data loss risk: DROP and ALTER operations are flagged prominently
Lock duration: DDL operations are assessed for table lock impact
Rollback completeness: Every upgrade must have a corresponding downgrade
Transaction safety: All operations must be wrapped in transactions
