Transform messy code into clean code through disciplined refactoring. Code smells, refactoring patterns, and the courage to improve without breaking. Leave every codebase better than you found it.

Orchestrate complete or partial feature implementation workflow with configurable phases. This skill should be used to run the full workflow (specification → research → plan → implement → test → fix) or specific phases, coordinating between all feature-implementation skills automatically.

Design reusable prompt templates that encode domain-specific patterns for recurring AI development tasks.Use this skill when you've executed similar prompts 2+ times and need to capture the pattern as reusableintelligence. Transforms one-off prompts into parameterized templates that maintain quality while reducingcognitive load. Helps students move from Layer 2 (AI Collaboration) to Layer 3 (Intelligence Design) inthe 4-Layer Teaching Method.

Asyncio patterns in Python for high-concurrency IO-bound tasks. Includes coroutines, task management, and asynchronous resource handling. Triggers: asyncio, python-async, coroutine, await, async-gather, async-generator, event-loop.

Print settings and optimization for Prusa Mini+ with E3D Revo Micro hotend, bowden direct drive extruder, and ObXidian nozzles (0.25mm, 0.4mm, 0.6mm, 0.8mm). Use when the user asks about print settings, slicer profiles, troubleshooting prints, material temperatures, flow rates, nozzle selection, or optimizing prints for this specific printer configuration. Triggers on phrases like "print settings", "slicer profile", "layer height", "print speed", "temperature", "first layer", "stringing", "calibration", "which nozzle", or any 3D printing task mentioning Prusa Mini, Revo, or ObXidian.

Official Anthropic SDK for Claude AI with chat, streaming, function calling, and vision capabilities

Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack to identify source of invalid data

A learning methodology skill based on Dr. Justin Sung's PACER system for effective information retention and application. Use when helping users (1) learn new material efficiently, (2) take notes or summarize content, (3) create study plans, (4) review or memorize information, (5) understand how to retain knowledge better, or (6) process educational content like books, lectures, courses, or articles.

Check Swift naming conventions for iOS code. Validates class names, variables, functions, and IBOutlets against project standards. Use when reviewing code readability, checking abbreviations, or enforcing naming consistency in Swift files.

Deploys applications to Cloudflare Pages including Functions, KV, D1, and R2 bindings. Use when deploying to the edge, building globally distributed applications, or using Cloudflare's ecosystem.

Diagnose and fix Flutter build failures, including dependency conflicts, Gradle errors, compilation issues, and platform-specific build problems. Use when builds fail locally or in CI.

Provides REQ-* key pattern definitions, validation rules, and traceability operations. Use for understanding requirement key formats, validating keys, or tracing requirements through the SDLC lifecycle.

Meta-skill for selecting correct WorldCrafter skill. Use when unclear which skill to use, request maps to multiple skills, need to orchestrate skills, user asks for guidance, or ambiguous requests need clarification. Provides decision trees and trigger matching for feature-builder (complete features with forms), database-setup (tables/migrations/RLS), test-generator (add tests), route-creator (simple pages/APIs), auth-guard (authentication/authorization), ai-assistant (AI generation/suggestions/consistency), visualization (maps/timelines/graphs), and chatgpt-setup (MCP integration). Do NOT use when request clearly maps to one skill or trigger phrases clearly indicate specific skill.
