Enhance AI Agent Skills: Change-the-Protocol Tool

Enhance AI Agent Skills: Change-the-Protocol Tool

The Change-the-Protocol Tool for AI agent skills offers developers the ability to add new optional fields to existing protocols used in AI coding agents like Claude Code, Cursor, and Codex. This tool ensures forward compatibility by allowing additions without disrupting current client implementations.

What this skill does

• Enables the addition of new optional fields or enum values to existing protocol decks.
• Supports version 1 protocol, ensuring that clients not recognizing new changes read defaults or ignore them, maintaining compatibility.
• Provides a structured approach by requiring changes in five critical locations: `PROTOCOL.md`, `crates/core/src/protocol.rs`, `diagram.rs`, and others.

Who it is for

• Developers who work with AI coding agents and need to extend or modify protocol functionalities.
• Engineering teams that manage large-scale AI applications requiring consistent protocol versioning.

Use cases

• Adding a new optional field to improve data handling without affecting legacy clients.
• Introducing new enum values to enable future expansions while ensuring backward compatibility.
• Implementing changes in a phased approach across multiple sections to ensure synchronicity within the development environment.

Technical details

• Works with AI coding agents such as Claude Code, Cursor, and Codex.
• Utilizes `serde` for serialization and deserialization, ensuring fields are not serialized unless necessary.
• Modification implementation across `crates/core/src/protocol.rs` and `diagram.rs` is required for full integration.
