## What it does and how to use it

A **skill** that teaches Claude Code to do scientific tasks well. It is packaged knowledge the model uses whenever it is relevant.

1. Install the skill (command above).
2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
3. No commands to memorize: you talk in plain language and the skill does the rest.

## Install (Claude Code)

```bash
mkdir -p .claude/skills/events && curl -fsSL https://doutorai.pt/data/lib/skills__events.md -o .claude/skills/events/SKILL.md
```

Paste this command into the terminal, in your project folder, and the component installs automatically.

# SimPy Events System

This guide covers the event system in SimPy, which forms the foundation of discrete-event simulation.

## Event Basics

Events are the core mechanism for controlling simulation flow. Processes yield events and resume when those events are triggered.

### Event Lifecycle

Events progress through three states:

1. **Not triggered** - Initial state as memory objects
2. **Triggered** - Scheduled in event queue; `triggered` property is `True`
3. **Processed** - Removed from queue with callbacks executed; `processed` property is `True`

```python
import simpy

env = simpy.Envi
