Answer questions about a codebase by examining its source files. Explains how components work and where definitions live, with file and line references, a key-files table, and diagrams for architecture or data flow.
Investigate how a specific part of a codebase works by tracing real implementations across files. Receive diagrams, tables, code references, and recommendations covering architecture, data flow, dependencies, and design risks, with facts distinguished from inference.
Turn Git commit history into a structured changelog grouped by date and change type. Combines related commits into clear descriptions, highlights changes that affect users, and adds migration notes for breaking changes.
Generate missing AGENTS.md files from a repository’s actual configuration and code. Gives coding agents folder-specific build commands, testing instructions, conventions, and working boundaries, with companion CLAUDE.md files that direct readers to the instructions.
Set up application registration and authentication with Microsoft Entra ID. Guides API permissions, credentials, and OAuth 2.0 flows, with MSAL authentication library examples for user sign-in and service-to-service access.
Create and update agents defined through configuration files for M365 Copilot and Teams. The skill guides project setup, external service connections, instruction reviews, multilingual support, and deployment with a link for testing.
Build MCP servers that display interactive widgets in M365 Copilot Chat. Covers React and Fluent UI interfaces, structured data responses, adding widgets to existing servers, local tunnel testing, and configuration for connecting tools to Copilot.
Implement secret storage and retrieval in Node.js applications with Azure Key Vault. Covers secret versions, expiration, deletion and recovery, plus examples for managing encryption keys, rotating them, and performing cryptographic operations.
Build text and image moderation in TypeScript with Azure AI Content Safety. Analyze harmful content by category and severity, manage custom lists of prohibited terms, and use the results to implement content review rules.
Build dark-themed React dashboards and admin panels with Tailwind CSS and Framer Motion. Apply consistent colors, reusable interface components, translucent glass-like surfaces, and animations for pages, cards, and buttons.
Create custom React Flow nodes for visual workflow editors using TypeScript templates. Covers typed node data, connection points, resizing controls, Zustand state integration, and registration steps to make nodes available on the canvas and in menus.
Build Python agents for Teams, Microsoft 365, and Copilot Studio. Covers message routing, aiohttp web hosting, MSAL authentication, and streaming responses that display text as it arrives, with examples for protected commands and conversations.
