stella-runtime-extension

What problem does it solve?

This Skill eliminates the complexity of modifying Stella's Pi-shaped runtime by providing clear, structured guidance for adding or updating agents, tools, lifecycle hooks, providers, and prompt templates, so you can extend Stella's functionality without navigating unorganized kernel internals.

Core Features & Use Cases

• Runtime Extension Guidance: Step-by-step instructions for adding markdown-based agents, core tools, lifecycle hooks, providers, and prompt templates to Stella's extension system.
• Built-in Runtime Management: Clear patterns for working with the existing stella-runtime built-in extension, including hook registration, agent prompt updates, and capability gating.
• Use Case: If you want to add a custom agent that handles your team's internal documentation queries, this Skill walks you through creating the markdown agent file, registering it via the extension loader, and adding any required tools or hooks without restarting Stella.

Quick Start

Use the stella-runtime-extension skill to add a new markdown-based agent that answers questions about your internal project documentation and registers it to Stella's runtime.
