Discover Development skills, compare source repositories and read the instructions for each workflow.
Ensures questions are answered literally before taking action. Triggers on user input containing '?' or patterns like 'why did you...?', 'will that work?', 'have you considered...?'. Use when user asks about yo...
Quick persona switching. Triggers: 'switch persona', 'switch to X', 'become X'. Lists personas, reads selected file, switches immediately.
This skill should be used when fixing bugs, implementing features, debugging issues, or making code changes. Ensures understanding of code flow before implementation by: (1) Tracing execution path with specific...
Strict test-driven development state machine with red-green-refactor cycles. Enforces test-first development, meaningful failures, minimum implementations, and full verification. Activates when user requests: '...
Systematic debugging methodology that eliminates guessing and speculation. Add instrumentation to gather specific data that fully explains the problem. Evidence before hypothesis. Observation before solution.
Comprehensive data visualization skill covering visual execution and technical implementation. Includes perceptual foundations, chart selection, layout algorithms, and library guidance. Load on-demand when buil...
FOLLOW THE STATE MACHINE IN SKILL.MD. When user says 'continue': (1) FIRST: Run pwd, (2) Announce STATE: CHECK_STATUS, (3) Read .claude/session.md to check Status field, (4) Route based on Status. NEVER auto-ad...
Principles for writing effective, maintainable tests. Covers naming conventions, assertion best practices, and comprehensive edge case checklists. Based on BugMagnet by Gojko Adzic.
Professional, skeptical communication style focused on critical thinking and coaching. Never over-enthusiastic, always verifies before agreeing, challenges ideas constructively. Use when you want a persona to a...
Creates well-formed tasks following a template that engineers can implement. Use when creating tasks, defining work items, creating tasks from PRD, breaking down features, or converting requirements into action...
This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures...
Force honest confidence assessment before claiming conclusions. Triggers on 'root cause identified', 'problem identified', 'complete clarity'. Express confidence as percentage, explain what's stopping 100%, val...
Generate production-quality Python code for sensor integration, sensor fusion, and perception systems that run in Pyodide (browser). Creates educational code for teaching IMU sensors, LiDAR simulation, depth pe...
Generate production-quality Python code for robot simulations that run in Pyodide (browser). Supports simplified physics simulations using NumPy, Matplotlib, and basic physics calculations. Creates educational...
Generate production-quality Python code for robot motion planning algorithms that run in Pyodide (browser). Creates educational code for teaching path planning (A*, RRT), trajectory optimization, PID control, m...
This skill should be used when evaluating the quality of book chapters, lessons, or educational content. It provides a systematic 6-category rubric with weighted scoring (Technical Accuracy 30%, Pedagogical Eff...
Plan, structure, and scaffold large educational books using cognitive load management, just-in-time specification, and pedagogical best practices. Use this skill when planning multi-part, multi-chapter educatio...
Autonomously execute exploratory implementation of one approach from spike definition, working independently until natural stop. Use when partner provides spike definition and assigns you an approach number to...
Transform project ideas into requirements documentation focusing on user outcomes and functionality, not implementation. Use when partner describes a new project or feature idea and needs a PRD capturing requir...
Execute implementation plans or backlog items autonomously with shared-context architecture for maximum accuracy
Use when working with any configuration file outside of project directories in ~/Code (unless already managed like ~/Code/CLAUDE.md) - handles chezmoi prefix mappings, template awareness, conflict resolution wo...
Debug visual and spatial bugs in Godot games through user observation, Godot-specific diagnosis, and test-driven fixes. Use when debugging visual or input issues in Godot where the user can observe the game but...
Create spike definitions with canonical names and numbered approaches for parallel exploratory implementation. Use when partner has an underdefined feature idea and wants to explore multiple implementation appr...
Analyzes project structure and generates appropriate Claude Code subagents based on detected tech stack
The default order uses GitHub repository stars from our indexed data. Stars belong to the source repository and may be shared by multiple skills. They indicate repository interest, not skill installs or an independent quality score.
