Master AI Extensions: Comprehensive SDK Reference Guide
The "Master AI Extensions: Comprehensive SDK Reference Guide" provides developers with an in-depth resource for creating and managing AI agent skills through the pi extension and PizzaPi packages. This resource offers a detailed understanding of the pi core extension API, including events, UI interfaces, tool registrations, command modules, and interaction with PizzaPi host systems, all tailored for AI coding agents such as Claude Code, Cursor, and Codex.
What this skill does
- Explains the creation of extensions as TypeScript modules that employ an asynchronous factory function.
- Details the process of subscribing to pi events, such as session_start and tool_call.
- Outlines how to register tools, commands, and shortcuts within the extension framework.
- Describes how to request user approvals via user interfaces and send messages to agents.
- Illustrates detection of the PizzaPi host and the method of sending service messages through the event bus and relay socket.
- Covers implementation of runner services, including HTTP panel exposure and event broadcasting.
- Provides insights into resolving sigils, formatted as [[type:id]] tokens.
Who it is for
This guide is designed for software developers and development teams focused on building AI agent extensions and enhancing AI coding capabilities using platforms like Claude Code, Cursor, and Codex.
Use cases
- Developers aiming to build custom tools and commands for AI coding agents.
- Teams looking to integrate and manage extension capabilities in AI-driven environments.
- Technical professionals needing to implement advanced workflows and service communications within AI platforms.
Technical details
- Utilises the pi core extension SDK (`@earendil-works/pi-coding-agent`) for foundational setup.
- Incorporates PizzaPi-specific SDK (`@pizzapi/extension-sdk`) for host detection and messaging.
- Emphasises the use of TypeScript for module development, ensuring wide compatibility and scalability.
- Focuses on daemon-side runner services for extending user session functionality and agent interaction.

Here's what buyers say about the skills they use every day.
Ran it on a client's Google Ads account and it flagged wasted spend we'd been missing for months. Paid for itself on day one.
Optimize Ad Spend: Ad Account AuditorWe finally caught broken conversion tags before launch instead of after. The pre-launch checklist alone is worth the price.
Optimize Conversion Tracking: Pre-Launch QADropped it into Claude Code and my LCP went from 4.1s to 1.9s in an afternoon. It explains every fix it suggests, so I actually learned something too.
Optimize Core Web VitalsOur agency uses it as the final review step on every PR now. It catches security issues our linters never did.
Optimize Your Code: Best Practices & SecurityMade WCAG 2.2 compliance actually manageable. It walked through our whole storefront and produced a fix list our devs could work from directly.
Enhance Web Accessibility: WCAG 2.2As an expat freelancer in France, the DGFIP simulation saved me a very expensive appointment with an accountant. Incredibly thorough.
AI Tax Audit Skill: DGFIP Fiscal ControlWorks with both Cursor and Claude Code exactly as advertised. Setup took less than five minutes with the included README.
Optimize Profits: AI Conversion Value MapperInstant delivery, clean files, clear docs. This is how digital products should be sold. Already bought three more skills.
AI Comptable: French AccountingSupport answered my install question within a couple of hours on a Sunday. The skill itself has become part of my daily workflow.
