kernel-extension

What problem does it solve?

This Skill provides extension points for the composable kernel so developers can implement custom per-turn logic, intercept or block tool calls, synthesize tool outputs, or replace the phase pipeline for new reasoning strategies.

Core Features & Use Cases

• Phase Extension: Define pure, Effect-based phases that read kernel state and return updated KernelState for enrichment, analysis, or reflection.
• Guard Rules: Implement synchronous guards that explicitly allow or block tool calls with reasons to enforce execution policies and safety constraints.
• MetaTools & Custom Kernels: Intercept named tool calls to synthesize results in-memory or compose a fully custom phase sequence for alternative reasoning strategies.
• Use Case: Create a strategy that inserts a pre-think enrichment phase, adds a guard to block unsafe tool names, and registers a MetaTool to return cached responses without external I/O.

Quick Start

Use the kernel-extension skill to add a pre-think phase that enriches per-turn context and register it in your kernel's phases array.
