// Capabilities

Built for serious agents

Native Pascal Core

Compiled, fast, and binary-small. No interpreter, no runtime tax.

Tool-Using Loop

Reason → call tool → observe → repeat. Built-in agent control flow.

Cross-Platform

FireMonkey + VCL targets: Windows, macOS, Linux, iOS, Android.

Streaming Output

Token-by-token streaming responses straight into your Pascal app.

Extensible Tools

Register custom Pascal procedures the model can invoke at runtime.

Open Source

MIT licensed. Built by the Delphi community, for the Delphi community.

// Pipeline

A simple agentic loop

01

Prompt

Send a user goal into the agent from any Pascal app.

02

Reason + Tool-call

PasClaw plans, invokes registered Pascal tools, and observes results.

03

Result

Streaming response delivered back to your UI or service.
