postkit

What problem does it solve?

This Skill solves the challenge of building production-ready authentication, authorization, versioned configuration, usage metering, and background job queues without wiring multiple external services.

Core Features & Use Cases

• Postgres-native SQL functions: Use directly from any language/driver to implement identity, permissions, config, metering, and job queues.
• Multi-module coverage: authn for users/sessions/tokens, authz for ReBAC relationship-based permissions, config for versioned key-value settings with rollback, meter for reservations and ledger-based usage tracking, and queue for scheduled/retryable jobs.
• Fast integration path: Build distribution SQL, install into your database, then call the needed schemas/functions in your app workflow.

Quick Start

Run make build to generate dist SQL files, then install the schema with psql $DATABASE_URL -f postkit/dist/postkit.sql, and finally call the relevant functions (for example authz.check for permission checks) using your database connection.
