Pgsql Test Jwt Context

What it does

This skill allows AI agents to securely test PostgreSQL database connections and execute queries using a JSON Web Token (JWT) for authentication. It extracts claims from the JWT, which are then used as context within SQL queries, enabling dynamic data access based on user roles or permissions. The skill supports both verifying existing JWTs and generating new ones for testing purposes.

When to use it

• Automated Testing: Verify database connection integrity and query execution in automated test suites without hardcoding credentials.
• Role-Based Access Control (RBAC) Simulation: Simulate different user roles and permissions by providing various JWT claims, ensuring RBAC policies are correctly enforced within the database.
• Secure Data Masking/Anonymization: Generate JWTs with limited claim scopes to test queries against masked or anonymized data sets in a development environment.
• Integration Testing: Test integrations between applications and PostgreSQL databases where authentication relies on JWTs.

Key capabilities

• JWT verification and decoding
• Extraction of claims from JWTs
• Dynamic SQL query construction using JWT claims as context
• Generation of test JWTs with specified claims
• Secure database connection management

Example prompts

• "Verify the provided JWT: [JWT Token] against my PostgreSQL database."
• "Generate a test JWT for user 'testuser' with role 'admin'."
• "Execute the query 'SELECT * FROM users WHERE department = $1' using the 'department' claim from this JWT: [JWT Token]."

Tips & gotchas

• Requires access to a PostgreSQL database and appropriate connection credentials.
• The skill relies on correctly formatted JWTs; ensure the token is valid and properly signed.
