Git & Version Control

This skill guides writing DigitalOcean infrastructure with OpenTofu/Terraform. Use when provisioning Droplets, VPCs, Managed Databases, Firewalls, or other DO resources.

Create new Claude Code skills with proper structure and best practices. Use when the user wants to create a new skill, extend Claude's capabilities, or needs help structuring a SKILL.md file.

Use when creating or refactoring Action Mailer emails. Applies Rails 7.1+ conventions, parameterized mailers, preview workflows, background delivery, and email design best practices.

Design comprehensive customer retention systems with health scoring, churn prediction, proactive engagement workflows, and customer success frameworks to maximize lifetime value.

This skill provides guidance for tasks involving merging git branches that contain different implementations of ARC-AGI pattern recognition algorithms, and then implementing a working solution that generalizes across examples. Use this skill when the task involves (1) merging git branches with conflicting code, (2) analyzing ARC-AGI style input/output grid transformations, or (3) implementing pattern recognition algorithms that must generalize to unseen test cases.

Use when creating or refactoring Stimulus controllers. Applies Hotwire conventions, controller design patterns, targets/values usage, action handling, and JavaScript best practices.

Task list management and execution for spec-driven development.Use when: executing implementation tasks, managing task progress, processing task list with git commits.Keywords: task execution, process-task, implementation, commit, task management, 任務執行, 實作, 任務清單.

Guidance for extracting weight matrices from black-box ReLU neural networks using only input-output queries. This skill applies when tasked with recovering internal parameters (weights, biases) of a neural network that can only be queried for outputs, particularly two-layer ReLU networks. Use this skill for model extraction, model stealing, or neural network reverse engineering tasks.

Build health audit worker (L3). Checks compiler/linter errors, deprecation warnings, type errors, failed tests, build configuration issues. Returns findings with severity (Critical/High/Medium/Low), location, effort, and recommendations.

Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. When Claude needs to fill in a PDF form or programmatically process, generate, or analyze PDF documents at scale.

Create user-focused, SEO-optimized changelog entries for software releases. Use when writing release notes, version updates, product changelogs, or "what's new" documentation for developer tools.

Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. When Claude needs to fill in a PDF form or programmatically process, generate, or analyze PDF documents at scale.

This skill implements test-driven development workflow using the red-green-refactor cycle. Use when building new features or fixing bugs that require test coverage. Framework-agnostic methodology that works with any testing framework and programming language. Triggers on requests to implement features using TDD, write tests first, or follow test-driven development practices.

Research a market, pinpoint an underserved customer pain, and design a venture that can capture the opportunity within 12 months. Comprehensive 10-step workflow from market mapping to 90-day action plan.

Write modern React components with TypeScript, hooks, and best practices. Creates functional components, custom hooks, and follows composition patterns.

Guide for recovering lost Git commits, resolving detached HEAD states, and fixing common Git repository issues. This skill should be used when users need help recovering from Git mistakes such as lost commits, detached HEAD situations, accidental resets, or when commits appear to be missing from branches.

This skill provides a complete workflow for handling GitHub Pull Request reviews, specifically optimized for @gemini-code-assist automated reviews. This skill should be used when addressing PR review comments, responding to reviewers, resolving threads, requesting re-reviews, or merging PRs after feedback is addressed. Triggers include: /pr-review command, "address PR feedback", "handle review comments", "respond to gemini", or any PR review lifecycle management request.

Extracts hidden or encoded text from GCODE files by analyzing toolpath geometry and coordinate data. This skill should be used when tasks involve decoding text from 3D printing files, recovering embossed or engraved text from GCODE, or CTF-style challenges involving GCODE analysis. Applies to any task requiring geometric reconstruction of text from CNC or 3D printer movement commands.

Manage git worktrees for parallel development. Use when the user wants to work on multiple branches simultaneously, create isolated environments for features/fixes, or clean up completed worktrees.

Guidance for solving ARC-AGI style pattern recognition tasks that involve git operations (fetching bundles, merging branches) and implementing algorithmic transformations. This skill applies when tasks require merging git branches containing different implementations of pattern-based algorithms, analyzing input-output examples to discover transformation rules, and implementing correct solutions.
