Guide for safely refactoring Python code using proven techniques, detecting code smells, and implementing improvements.

Skill for developing, maintaining, and extending Obsidian's MCP server with code patterns, architecture, testing, and package management.

Provides utilities for running, managing, and debugging tests with common patterns and fixtures to streamline software development testing processes.

Enforces consistent TypeScript coding standards for writing and reviewing code in .ts and .tsx files.

Provides Electron desktop app patterns for PhotoVault bulk uploader, including main/renderer communication, chunked uploads, and security for large file handling.

Analyzes coding sessions to detect user preferences and corrections, then proposes targeted improvements to code skills and codifies them into skill files.

Automates Git version control tasks including commits, changelogs, and releases to streamline code versioning and publishing workflows.

Adds shadcn/ui components to the Gooey custom component library for consistent UI development.

Provides end-to-end development guidance for responsive React mobile web applications with performance optimization, PWA implementation, and touch interaction support.

Creates comprehensive test cases for user flows and end-to-end testing to validate feature functionality and coverage.

Manages Git worktrees for repository isolation, enabling parallel development on different branches without context switching.

Enforces and automates Rust crate conventions including layout, formatting, linting, testing, and benchmarking for consistent development.

Reviews user stories for clarity, completeness, and feasibility from a developer's perspective to ensure implementation readiness.

Intelligently splits mixed Git changes into semantic, conventional commits for cleaner version control history.

Provides AI-driven design feedback from Gemini and Codex for architecture decisions and design reviews in software development projects.

Enables deterministic integration testing for Java applications, covering external dependencies (DB, queues, IO) with fixture strategies and CI compatibility.

Provides Kafka producer/consumer patterns with at-least-once semantics, DLQ handling, and schema evolution for event-driven features and issue diagnosis.

Creates Stripe webhook handlers to process payment events and enable real-time synchronization with the stripe-sync-engine.

Generates NPC profiles from YAML input and saves JSON output to the designated directory without external dependencies.
