Interactive project initialization with git setup, workflows, hooks, and build configuration. Triggers: project setup, initialization, scaffold, bootstrap, new project Use when: starting new projects or initializing repositories

Transform specifications into structured implementation plans with architecture design and task breakdown

Analyze and enhance Makefiles for complete user functionality coverage. Triggers: Makefile analysis, Makefile gaps, missing targets, plugin release, Makefile coverage, build targets, make dogfood, plugin quality Use when: analyzing Makefile completeness before releasing plugins, identifying gaps during plugin maintenance, scoring Makefiles against best practices, verifying Makefiles support standard developer workflows DO NOT use when: writing initial Makefiles from scratch. DO NOT use when: debugging specific build target failures. DO NOT use when: creating custom non-standard build systems. Use this skill BEFORE releasing any plugin to verify Makefile coverage.

Qwen CLI delegation workflow implementing delegation-core for Alibaba's Qwen models. Triggers: qwen cli, qwen delegation, alibaba qwen, qwen batch, multi-file analysis, qwen summarization, qwen extraction, 100K context Use when: delegation-core selected Qwen, need Qwen's large context capabilities, batch processing or multi-file analysis required DO NOT use when: deciding which model to use - use delegation-core first. DO NOT use when: qwen CLI not installed or configured. Consult this skill when implementing Qwen-specific delegation workflows.

Post-process video files and generate optimized GIFs. Converts webm/mp4 to GIF with configurable quality settings. Triggers: gif conversion, video to gif, optimize gif, webm to gif Use when: converting browser recordings to GIF format, optimizing GIF file size

Competence in data analytics and machine learning, enabling developers to build data-driven features and integrate AI/ML capabilities.

The practice of restructuring and simplifying code continuously – reducing complexity, improving design, and keeping codebases clean.

承認済みの設計書（DESIGN.md）からTDD準拠のTODO.mdを作成します。analyzing-requirementsスキルで設計が完了・承認された後に使用します。developingスキルで実装できる形式のタスクリストを生成します。

Creates syntactically correct mermaid diagrams (flowchart, sequenceDiagram, classDiagram, stateDiagram, erDiagram, gantt, mindmap) following official specifications. Prevents common errors like special characters in labels, subgraph syntax, note misuse, and reserved words. Use when creating or editing mermaid diagrams in documentation or design files.

ユーザー要件を分析し、システム設計ドキュメント(DESIGN.md)を生成します。ユーザー要件が曖昧または不明確な場合、システムアーキテクチャの設計が必要な場合、大規模な機能開発の設計仕様が必要な場合、技術的実現可能性の検証が必要な場合に使用します。不明点はAskUserQuestionツールで確認します。

Generate or edit images using Google Gemini API via nanobanana. Use when the user asks to create, generate, edit images with nanobanana, or mentions image generation/editing tasks.

Transcribes video audio using WhisperX, preserving original timestamps. Creates JSON transcript with word-level timing. Use when you need to generate audio transcripts for videos.

Sets up a Mac for ButterCut. Installs all required dependencies (Homebrew, Ruby, Python, FFmpeg, WhisperX). Use when user says "install buttercut", "set up my mac", "get started", "first time setup", "install dependencies" or "check my installation".

Creates video rough cut yaml file for use with Buttercut gem. Concatenates visual transcripts with file markers, creates a roughcut yaml with clip selections, then exports to XML format. Use this skill when users want a "roughcut", "sequence" or "scene" generated. These are all the same thing, just with different lengths.

Extract subtitles/transcripts from a YouTube video URL and save as a local file. Use when you need to extract subtitles from a YouTube video.

Creates compressed ZIP backups of libraries directory. Backs up library.yaml, transcripts, and roughcuts (not video files). This skill can also be useful when you need to restore a library.

Adds visual descriptions to transcripts by extracting and analyzing video frames with ffmpeg. Creates visual transcript with periodic visual descriptions of the video clip. Use when all files have audio transcripts present (transcript) but don't yet have visual transcripts created (visual_transcript).

Use when user wants to execute long-running tasks that require multiple sessions to complete. This skill manages task decomposition, progress tracking, and autonomous execution using Codex non-interactive mode with auto-continuation. Trigger phrases include autonomous, long-running task, multi-session, 自主执行, 长时任务, autonomous skill.

Creates a new ButterCut release with version bump, changelog, git tag, gem build, and GitHub release. Use when publishing a new version.

Interactive feature development workflow from idea to implementation. Creates requirements (EARS format), design documents, and implementation task lists. Use when creating feature specs, requirements documents, design documents, or implementation plans. Triggered by "kiro" or references to .kiro/specs/ directory.
