# Task Generator

> How Simulation Lab generates tasks from templates, seed data, NPCs, and toolsets

The Task Generator produces complete task bundles by combining four inputs through an iterative generation process.

## Inputs

* **Template** (`task.json`) — The structural blueprint that defines the task format and constraints.
* **Seed Data** — Domain-specific records injected into the playground (e.g., employee records, resumes, job requisitions).
* **NPCs** — Simulated users with defined interests and personality traits that interact with or are referenced by the task.
* **Toolset** — The available tools described by their descriptions, schemas, and dynamics.

## Iterative Task Generation

The generator combines these inputs and iteratively improves the output for:

* **Grounding in seed data** — Tasks reference real data present in the playground.
* **Realism** — Instructions reflect plausible real-world scenarios.
* **Feasibility with toolset** — Tasks are solvable using the available tools.
* **Diversity** — Generated tasks cover a range of scenarios and difficulty levels.

## Skills.md

Each task is paired with a `Skills.md` file that provides the agent with:

* **Scenario context** — Background information about the task domain and situation.
* **Recurring workflows** — Common patterns and procedures the agent should follow.

## Task Bundle Output

A generated task bundle contains:

* **Task metadata** — Unique ID, display name, difficulty, and category.
* **Task instruction** — The natural language instruction given to the agent.
* **Tool servers** — Which tool servers are required.
* **Seed data** — Data injected into the playground before the agent starts.
* **Verifiers** — Automated checks that determine whether the agent succeeded.
