## What it is
Cordis is a TypeScript meta-framework for building composable plugin-based applications, centered on a service container (context) with dependency injection, typed events, and reversible side-effect registration. It provides lifecycle management with automatic teardown, multiple event dispatch modes (emit, waterfall, parallel, serial), and is used as the underlying plugin framework for AI agent harnesses.

## Use cases
- build a plugin-based application with dependency injection
- structure services with typed events and lifecycle hooks
- compose AI agent tools and pipelines as plugins
- implement middleware-style request wrapping with waterfall events
- manage reversible registrations with automatic teardown on reload

## When to choose
- you want a service container with declarative dependency injection in TypeScript
- you need plugin hot-reloading with guaranteed resource disposal
- you are building an extensible system where plugins communicate via typed events

## When to avoid
- you need a simple script or one-off tool without plugin architecture
- your team is not comfortable with TypeScript and advanced type-system patterns
- you want a batteries-included web framework with routing and HTTP built in
