当用户要求 AI 直接操作他的 macOS 桌面时触发：打开某个 App、点击某个按钮、填写窗口里的表单、读取当前屏幕内容、自动化本地 GUI 流程。典型说法"帮我在访达里…"、"帮我在某 App 里点一下…"、"看看我屏幕上显示的是什么"。**仅在 OpenLoaf Desktop（macOS）中可用**；非桌面端会返回 desktop-only 错误，应改用 `BrowserAct` 或让用户自己操作。**不用于**：网页内交互（→ `browser-ops-skill`）、本地文件读写（→ `Read`/`Edit`/`Write`）。

Triggered when the user asks for page-level interaction with a specific webpage: login, form filling, button clicks, pagination scraping, screenshots, downloading page images, handling CAPTCHAs or anti-bot measures, accessing SPA dynamic content; also used as a fallback when WebFetch returns an empty shell or gets blocked. Typical phrasing: "log me into X then scrape Y", "take a screenshot". **Not for**: factual questions or "what is xx" (→ `WebSearch`), or simply reading static webpage text (try `WebFetch` first).

Guides RESTful API endpoint design, resource naming, status code selection, pagination structure, versioning strategy, and error response schemas. Use when the user asks about designing APIs, defining HTTP endpoints, REST conventions, API versioning, request/response formats, URL structure, OpenAPI/Swagger specs, or reviewing an existing API contract for best practices.

Reliably inspect, create, edit, validate, and transfer files in a Windows-hosted WSL workspace. Use when a task names a WSL path, a `\\wsl.localhost` path, a Windows/WSL project location, or when remote file writes, UNC paths, mounted workspaces, and WSL shell execution may disagree.

Generate and validate shareable PowerShell or Bash command references from an explicitly supplied, non-sensitive command dump. Use when maintaining agent-readable command documentation, validating its JSON contract, or regenerating Markdown/JSON/YAML references without committing personal command histories, credentials, hostnames, or private filesystem paths.

Operate and automate a lossless music library with beets — intake/import loops, tagging policy, quality-ranked deduplication (WAV > FLAC > lossy), fingerprints, quarantine-not-delete policy, and library maintenance. Use whenever a task involves beet/beets commands, music library imports, tagging, dedup, fingerprinting, duplicate cleanup, lossless archive management, or beets configuration — even if the user just says "organize my music", "clean up duplicates", or "import these albums" without naming beets.

This skill should be used when the user asks to "sign this PDF", "fill in this form", "add my signature to", or mentions signing letters, claim forms, or contracts. Overlays a signature image, ticks checkboxes, and fills date/name/phone fields on scanned or digital PDFs using pymupdf, with OCR fallback for scanned documents.

Frontend specialist for Next.js 16 App Router + React 19 + Tailwind + Shadcn UI using Feature-Sliced Design Lite (domain-grouped features/, not traditional layers).

Use when designing new screens, redesigning existing UI, creating visual concepts, or improving interfaces in Nicolify. Executes a 7-phase creative Design Thinking workflow: defines user personas, frames problems, audits existing components (Shadcn UI + Tailwind CSS v4 + FSD architecture), researches SaaS UI patterns, proposes multiple distinct layout paradigms with ASCII wireframes and HTML mockups, iterates through dialogue, and delivers a complete UI-SPEC.md with component trees, data flow, responsive behavior, and interaction patterns — all following Nicolify's design tokens and codebase conventions. Triggers: 'diseña', 'rediseña', 'nueva pantalla', 'concepto visual', 'propuesta de diseño', 'UX', 'layout', 'prototipo', 'mejora la interfaz', 'wireframe', 'mockup', 'esquema de color', 'componentes de pantalla'.

Generate, audit, and compress AI-optimized documentation for codebases. This skill applies research-backed principles from three peer-reviewed papers to create documentation that maximizes AI agent performance instead of degrading it. Use this skill whenever the user asks to "write docs", "create a CLAUDE.md", "document a module", "audit documentation", "compress docs", "optimize docs for AI", "write module docs", "create domain documentation", "review doc quality", or mentions documentation bloat, token waste, or AI context efficiency. Also trigger when the user references "ai-docs principles", "telegram style docs", or wants to apply the "Lost in the Middle", "Less is More", or "AGENTS.md" research findings.

UX agéntico Luana v4 (post pm-redesign 2026-05 Punto 4). Diseña FLUJOS CONVERSACIONALES (no UI tradicional) para agentic-stories state=refining. Toma 01-spec.md (de /po) y produce 02-design-agentic.md en docs/product/stories/{story-id}/ con: turn-by-turn happy path, state machine agente, tools sequence, prompt slot architecture, voice constraints, error recovery, eval policy (personas+rubrics+pass^k), cost/latency budget, observabilidad. Al ratificar diseño → transition state=refining→refined. Carga skills sales-agent-expert, copilot-expert, tessl__langgraph, claude-api. Si descubre edge cases → delta-spec.md → /po ratifica. Activa cuando user dice: '/ux-agentico', 'diseñemos el flujo conversacional', 'cómo conversa el agente', 'flujo del copilot', 'turn-by-turn', 'experiencia agéntica'.

Manage Tessl tiles — search, install, update, and list versioned docs for project dependencies. Use when the user asks about Tessl tiles, adding or finding a tile, updating dependency docs, checking tile versions, or managing package documentation with Tessl. Covers add tile, find tile, tile version, dependency management, and curated version-pinned library docs.

Full production deployment pipeline: merge development to main, run /test-all fixing all errors, commit, push to trigger GitHub Actions, and monitor the workflow until deployment completes. Use when the user says "pase a producción", "hagamos un pase", "deploy to production", "pasamos a prod", "subamos a producción", or "vamos a producción".

Use cuando reportes/investigues bug del copilot module: loops infinitos, cards faltantes, conversaciones vacías al refresh, extracción que falla, trazas que mienten, tools que no ejecutan, costos disparados, routing equivocado, prompt cache roto, mutaciones que no persisten, channel format ignorado, voseo en outputs. Activa también para extender (agregar provider, tool, workflow, channel, KB chunk) sin romper invariantes. Triggers: 'bug copilot', 'loop copilot', 'card no aparece', 'conversación vacía', 'documento no extrae', 'agente no responde', 'tool no ejecuta', 'trazas mienten', 'tokens burned', 'extract_document_to_fields falla', 'propose_field_updates no persiste', 'format_for_channel ignored', 'voseo en respuesta', 'cache hit rate', 'cuántos tokens', 'agregar provider', 'agregar workflow', 'agregar tool transversal', 'agregar canal'.
