database-migration-manager
managing-database-migrations: This skill enables Claude to manage database schema changes through version-controlled migrations. It is activated when the user requests to create, apply, or rollback database migrations. The skill supports generating timestamped migration files with both up and down migrations for PostgreSQL, MySQL, SQLite, and MongoDB. It helps in tracking schema evolution and ensuring safe database modifications. Use this skill when the user mentions "database migration", "schema change", "add column", "rollback migration", or "create migration".

Overview
This skill empowers Claude to handle database migrations, including creating new migrations, applying changes, and rolling back previous modifications. It ensures that database schema changes are managed safely and efficiently.
How It Works
- Migration Request: The user requests a database migration task (e.g., "create a migration").
- Migration File Generation: Claude generates a timestamped migration file, including both "up" (apply changes) and "down" (rollback changes) migrations.
- Database Support: The generated migration file is compatible with PostgreSQL, MySQL, SQLite, or MongoDB.
When to Use This Skill
This skill activates when you need to:
- Create a new database migration file.
- Add a column to an existing database table.
- Rollback a previous database migration.
- Manage database schema changes.
Examples
Example 1: Adding a Column
User request: "Create a migration to add an 'email' column to the 'users' table."
The skill will:
- Generate a new migration file with timestamped name.
- Populate the 'up' migration with SQL to add the 'email' column to the 'users' table.
- Populate the 'down' migration with SQL to remove the 'email' column from the 'users' table.
Example 2: Rolling Back a Migration
User request: "Rollback the last database migration."
The skill will:
- Identify the most recently applied migration.
- Execute the 'down' migration script associated with that migration.
- Confirm the successful rollback.
Best Practices
- Idempotency: Ensure your migrations are idempotent, meaning they can be applied multiple times without unintended side effects.
- Transactions: Wrap migration steps within transactions to ensure atomicity; either all changes succeed, or none do.
- Naming Conventions: Use clear and descriptive names for your migration files (e.g.,
YYYYMMDDHHMMSS_add_email_to_users).
Integration
This skill can be used independently or in conjunction with other plugins for database management, ORM integration, and deployment automation.

evaluating-machine-learning-models: This skill allows Claude to evaluate machine learning models using a comprehensive suite of metrics. It should be used when the user requests model performance analysis, validation, or testing. Claude can use this skill to assess model accuracy, precision, recall, F1-score, and other relevant metrics. Trigger this skill when the user mentions "evaluate model", "model performance", "testing metrics", "validation results", or requests a comprehensive "model evaluation".
building-neural-networks: This skill allows Claude to construct and configure neural network architectures using the neural-network-builder plugin. It should be used when the user requests the creation of a new neural network, modification of an existing one, or assistance with defining the layers, parameters, and training process. The skill is triggered by requests involving terms like "build a neural network," "define network architecture," "configure layers," or specific mentions of neural network types (e.g., "CNN," "RNN," "transformer").
