Writes failing tests first for test-driven development and hands off a strict implementation contract that requires agents to make those tests pass without weakening the tests. Use when users ask for test-first workflows, RED/GREEN cycles, or behavior-gating tasks with automated tests.

Standardize and validate SKILL.md files against the Agent Skills specification (agentskills.io). Use when creating new skills, auditing existing skills for spec compliance, converting legacy skill formats to standard structure, or improving descriptions for reliable triggering. Triggers on: "validate skill", "create SKILL.md", "standardize skill format", "check skill spec", "skill frontmatter", "improve skill description", "add evals to skill".

here.now lets agents publish websites and store private files in cloud Drives. Use Sites to publish HTML, documents, images, PDFs, videos, and static files to live URLs at {slug}.here.now or custom domains. Use Drives as private cloud folders where agents can store files (documents, context, memory, plans, assets, media, research, code, etc), share them with other agents, and continue across sessions and tools. Use when asked to "publish this", "host this", "deploy this", "share this on the web", "make a website", "put this online", "create a webpage", "generate a URL", "build a chatbot", "save this to my Drive", "store this for later", "write this to cloud storage", "share a folder with another agent", or "use my here.now Drive".

小红书（RedNote）内容工具。使用场景： - 搜索小红书笔记并获取详情 - 获取首页推荐列表 - 获取帖子详情（正文、图片、互动数据、评论） - 发表评论 / 回复评论 - 获取用户主页和笔记列表 - 点赞、收藏帖子 - 发布图文或视频笔记 - 热点话题跟踪与分析报告 - 帖子导出为长图 触发词示例： - "搜一下小红书上的XX" - "跟踪一下小红书上的XX热点" - "分析小红书上关于XX的讨论" - "小红书XX话题报告" - "生成XX的小红书舆情报告"

Find bugs, security vulnerabilities, and code quality issues in local branch changes. Use when asked to review changes, find bugs, security review, or audit code on the current branch.

Use for pybytesize/ByteSize tasks: parsing size strings, converting bytes to metric/binary units, formatting human-readable sizes, readable unit selection, block alignment, and ByteSize arithmetic. Triggers "pybytesize", "ByteSize", "format bytes", "human readable size", "MiB/MB", "GiB/GB", "bytes to string", "parse size string", or requests for block-aligned size calculations.

Python code quality with Ruff linting/formatting and ty type checking. Use when configuring Ruff rules, setting up ty type checking, writing pyproject.toml quality config, creating pixi quality tasks, enforcing type annotations, or fixing lint errors—e.g., "set up ruff and ty", "configure Python linting", "add type checking to project", "fix ruff violations".

Azure DevOps Pipelines logging-command guidance for reliable script-to-agent signaling, variable passing, and log UX. Use when writing or debugging `##vso[...]` and `##[...]` commands in YAML/Bash/PowerShell pipelines, troubleshooting output variable scope, handling secrets and masking behavior, or publishing summaries/artifacts from scripts. Pair with `azuredevops-pipelines-template` when template architecture and logging semantics are both in scope.

Generate format-controlled research reports with evidence tracking, citations, and iterative review. This skill should be used when users request a research report, literature review, market or industry analysis, competitive landscape, policy or technical brief, or require a strict report template and section formatting that a single deepresearch pass cannot reliably enforce.

Extract clean markdown content from web pages using Defuddle CLI, removing clutter and navigation to save tokens. Use instead of WebFetch when the user provides a URL to read or analyze, for online documentation, articles, blog posts, or any standard web page. Do NOT use for URLs ending in .md — those are already markdown, use WebFetch directly.

Interact with Obsidian vaults using the Obsidian CLI to read, create, search, and manage notes, tasks, properties, and more. Also supports plugin and theme development with commands to reload plugins, run JavaScript, capture errors, take screenshots, and inspect the DOM. Use when the user asks to interact with their Obsidian vault, manage notes, search vault content, perform vault operations from the command line, or develop and debug Obsidian plugins and themes.

Look up prior Claude Code sessions when context is lost or forgotten. Use when asked "what did we do before?", "what happened in the last session?", "I forgot what we were working on", "find what I told you about X", or any request to recall past conversation history, prior decisions, experiments, or outcomes. Searches raw JSONL transcripts from ~/.claude/projects/ via DuckDB index. Returns verbatim user messages and summarizes AI actions and sub-agent outcomes. Summaries cached at ~/.claude/kaizen/session-summaries/.

Create user-facing App Store release notes by collecting and summarizing all user-impacting changes since the last git tag (or a specified ref). Use when asked to generate a comprehensive release changelog, App Store "What's New" text, or release notes based on git history or tags.

Scaffold, build, and package SwiftPM-based macOS apps without an Xcode project. Use when you need a from-scratch macOS app layout, SwiftPM targets/resources, a custom .app bundle assembly script, or signing/notarization/appcast steps outside Xcode.

Enforces the Airbnb iOS Swift Style Guide on Swift code. Use this skill any time the user wants to: review Swift code for style compliance, lint or audit an iOS codebase, apply Airbnb Swift conventions to new or existing code, understand why code violates Airbnb style rules, or get corrected rewrites of Swift snippets. Triggers on any request mentioning Swift code quality, iOS code review, Airbnb style, linting Swift files, or when the user pastes Swift code and asks for feedback, fixes, or a review. Also use when the user asks to "clean up" or "format" Swift code, or asks "is this good Swift?" — even if they don't mention Airbnb by name.

Diagnose Swift Concurrency issues, refactor callback-based code to async/await, and guide Swift 6 migration when working with tasks, actors, @MainActor, Sendable, data races, thread safety, or concurrency-related compiler and linter warnings.

Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file. Concrete actions include adding Sendable conformance, applying @MainActor annotations, resolving actor isolation warnings, fixing data race diagnostics, and migrating completion handlers to async/await.

Use when implementing Auth0 authentication in Nuxt 3/4 applications, configuring session management, protecting routes with middleware, or integrating API access tokens - provides setup patterns, composable usage, and security best practices for the @auth0/auth0-nuxt SDK

Generate a deep, code-first project wiki and VitePress documentation site (DeepWiki-style) for a repository. Use when asked to create a complete wiki/manual for a new codebase, build a code-first documentation site, or generate a `codewiki/` folder with structured Markdown, diagrams, and navigation based on the source code (not existing docs).

Build, audit, and improve Claude Code skills through guided interview and generation. Use when user says "create a skill", "build a skill", "make a new skill", "write a skill", "improve this skill", "audit this skill", "review my skill", "skill from scratch", "turn this into a skill", or /skill-builder. Produces guide-compliant skill directories with SKILL.md, references, and scripts.
