Skill UI

A comprehensive skill for generating new design screens from text prompts or images, and iteratively editing existing designs. It incorporates advanced prompt enhancement, design tokens, and professional UI/UX terminology to ensure professional, structured, and context-aware design output for web and mobile platforms.

A comprehensive skill for establishing a single source of truth for design tokens within Stitch. This tool guides users through retrieving project assets, synthesizing design rules from existing screens or descriptions, creating/updating the central design system, and systematically applying these tokens across all project screens to ensure UI consistency.

This comprehensive guide and tool suite transforms web designs created in Stitch (HTML/CSS) into clean, production-ready React Native components. It meticulously maps HTML elements (like <div>, <button>) to native RN primitives (View, Pressable) and converts complex CSS styles (Flexbox, typography, shadows) into React Native's StyleSheet.create(). It guides developers to follow architectural best practices, including Atomic Design and data decoupling, for scalable cross-platform mobile development.

This skill provides a robust method for uploading local digital assets, including images, mockups, and full HTML files, to a Stitch project. It bypasses the limitations of standard tool calls by streaming files directly over HTTP, ensuring that large visual assets or complex web pages can be processed accurately for your design and prototyping workflow. Ideal for integrating local design iterations into cloud-based prototypes.

A generic entry point for delegating self-contained, multi-step tasks to specialized LLM agents (Codex, Claude Code, Pi). Utilizes background processing tools to manage the full lifecycle of AI-driven sub-tasks, such as policy review, complex report synthesis, document generation, or large-scale code refactoring. Ideal for meta-skill workflows requiring full agent agency.

This utility burns an SRT subtitle track directly into an MP4 video file using ffmpeg's libass filter. It re-encodes the video (H.264) while copying the audio untouched. It supports defining custom font fallback chains (e.g., CJK fonts) and provides detailed control over font size, margins, and video encoding parameters (CRF, preset) for professional subtitling workflows.

This skill helps users condense large amounts of text into actionable, structured summaries. Whether you need key takeaways, detailed explanations, or identified action items, the output is meticulously formatted into Key Points, supporting Details, and necessary Action Items. Ideal for analyzing reports, academic articles, or meeting transcripts.

This tool standardizes the process of triaging and responding to customer support tickets, emails, or chats. It analyzes incoming text to identify issue type, product area, and severity, then categorizes the ticket, sets a priority level, drafts an empathetic response, and generates internal action items for efficient handling across platforms like Zendesk or Intercom.

This skill reads the contents of a UTF-8 text file and outputs the raw bytes verbatim to stdout. It is designed for meta-skills that require round-tripping an artifact through disk for user inspection or manual editing between steps. Unlike standard file readers that prepend line numbers, this tool preserves the original structure, making it ideal for structured data formats like YAML, scripts, or SRT files that need to be accurately parsed downstream.

A utility to generate a static, centered title or end card PNG image. It accepts a main headline, an optional subtitle, background color, and dimensions. It utilizes Pillow, ensuring deterministic rendering suitable for video intros and outros. Supports CJK character wrapping and provides robust font fallbacks, making it reliable for media production pipelines.

Provides comprehensive, programmatic control over tmux sessions. Users can list, capture output from, send specific keystrokes, and programmatically navigate panes/windows in remote, long-running interactive CLI sessions. Essential for monitoring AI code generation tools (like Claude/Codex) or managing complex multi-terminal workflows via scripting.

This tool concatenates multiple numbered MP4 segments (e.g., 1_*.mp4, 2_*.mp4) into a single cohesive video file. It provides advanced features like optional fade transitions and automatic normalization of resolution, frame rate, and codecs. Use it when a workflow generates several short clips that need to be seamlessly stitched together into a final, polished reel.
