Skillscript: Local Agent Orchestration Language

sshwarts · hn · 2026-07-12

Skillscript is a lightweight declarative language for orchestrating local agent tool calls. The author aims to write "how-to" processes as readable, version-controlled programs rather than relying on the model for on-the-fly reasoning.

It supports variables, conditions, and tool calls (MCP connectors, local models, restricted shell commands) while deliberately restricting capabilities: no eval, arbitrary imports, subprocesses, or infinite loops. The author emphasizes that this makes processes more controllable and auditable, making it ideal to hand off complex but fixed tasks to local small models.

Currently at version 0.30, it supports MCP, is self-hostable, but remains pre-1.0: initial setup is cumbersome, syntax is still evolving, and local model integration defaults to Ollama. The author uses it daily but notes it isn't production-ready yet.
