# ModelMux Task Index

> **Source**: Tasks derived from [plan.md](../plan.md). Each task maps to specific plan steps.  
> **Format**: Each task follows [AGENT.md](../AGENT.md) and [tools/task_template.md](../tools/task_template.md).

## How to Use

1. **Pick a task** from the phase you're working on
2. **Open the task file** (e.g. `TASK-001-integration-tests.md`)
3. **Follow the phases** — update status as you progress
4. **Log errors** in the task's Errors Encountered section
5. **Mark complete** when all acceptance criteria are met
