update-gitignore
Creates or updates a .gitignore file using git-agent AI generation. This skill should be used when the user asks to "update gitignore", "create gitignore", "add ignore rules", or needs to initialize ignore rules for a project.
Best use case
update-gitignore is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Creates or updates a .gitignore file using git-agent AI generation. This skill should be used when the user asks to "update gitignore", "create gitignore", "add ignore rules", or needs to initialize ignore rules for a project.
Teams using update-gitignore should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

update-readme
Updates README.md and README.zh-CN.md to reflect the project's current state. Use this skill whenever the user asks to "update the README", "sync the docs", "update documentation", "reflect latest changes in README", or wants both the English and Chinese READMEs to match the current project. Always triggers when the user mentions updating or regenerating README files, especially for bilingual (EN/ZH) projects.
swiftui-review
Reviews SwiftUI code for best practices on modern APIs, maintainability, and performance. This skill should be used when the user asks to review SwiftUI code, check for deprecated iOS/macOS APIs, validate data flow patterns, or audit accessibility compliance in Swift projects.
writing-plans
Creates executable implementation plans that break down designs into detailed tasks. This skill should be used when the user has completed a brainstorming design and asks to "write an implementation plan" or "create step-by-step tasks" for execution.
systematic-debugging
Provides a systematic debugging methodology with a 4-phase root cause analysis process. This skill should be used when the user reports a bug, error, test failure, or unexpected behavior, ensuring thorough investigation precedes any code changes.
need-vet
This skill should be used when the user invokes /need-vet to enable work verification for the current task. Claude must verify completion and append the verified tag before the session can end.
executing-plans
Executes written implementation plans efficiently using agent teams or subagents. This skill should be used when the user has a completed plan.md, asks to "execute the plan", or is ready to run batches of independent tasks in parallel following BDD principles.
build-like-iphone-team
Applies Apple's Project Purple design philosophy for radical innovation. This skill should be used when the user wants to challenge industry conventions, approach open-ended problems requiring disruptive thinking, or when standard brainstorming needs a breakthrough approach.
brainstorming
Structures collaborative dialogue to turn rough ideas into implementation-ready designs. This skill should be used when the user has a new idea, feature request, ambiguous requirement, or asks to "brainstorm a solution" before implementation begins.
behavior-driven-development
Applies behavior-driven development principles including Gherkin scenarios and test-driven development. This skill should be used when the user asks to implement features, fix bugs, or when writing executable specifications and tests before writing production code.
agent-team-driven-development
Provides guidance on coordinating multiple specialized teammates working in parallel. This skill should be used when the user needs to execute complex implementation plans, resolve cross-cutting concerns, or coordinate independent work streams requiring communication.
shadcn
Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".
refactor
Executes automated refactoring for specific files, directories, or semantic queries. This skill should be used when the user asks to refactor specific files or directories, simplify recently changed code, clean up dead code in a limited scope, or invokes "/refactor".
