Portability Across Runtimes

How one skill format operates across six agent runtimes.

What It Does

Technical notes exploring how skill files translate across Claude Code, Cursor IDE, Google Antigravity, ChatGPT Custom GPTs, OpenClaw, and local models via Ollama.

Architecture and Design Rationale

Developers frequently switch agent interfaces. Normalizing skill files into universal instructions ensures behavioral consistency across different environments.

When to Activate

  • •Configuring agent skills across diverse development environments

## Overview
Technical notes exploring how skill files translate across Claude Code, Cursor IDE, Google Antigravity, ChatGPT Custom GPTs, OpenClaw, and local models via Ollama.

## Rationale
Developers frequently switch agent interfaces. Normalizing skill files into universal instructions ensures behavioral consistency across different environments.

## Core Principles
* Always verify environment constraints and dependencies before executing.
* Enforce negative constraints and reject speculative abstractions.
* Validate output against stated acceptance rubrics.

## Execution Workflow
1. Discovery: Map requirements and inspect active context.
2. Decomposition: Break down the task into discrete, verifiable phases.
3. Execution: Implement surgical changes preserving existing code architecture.
4. Verification: Test all criteria before declaring completion.
