Interactive selector and router for architecture paradigms. Triggers: architecture selection, pattern comparison, system design, ADR creation, architecture decision, paradigm evaluation, new system architecture, architecture planning, which architecture, compare architectures Use when: selecting architecture patterns for new systems, comparing paradigm trade-offs, creating architecture decision records, evaluating architecture fit for team size and domain complexity, planning implementation roadmaps DO NOT use when: implementing a specific known paradigm - use the specific architecture-paradigm-* skill (hexagonal, layered, microservices, etc.) instead. DO NOT use when: reviewing existing architecture - use architecture-review instead. Use this skill BEFORE making architecture decisions. Check even if unsure about needs.

Methodology for summarizing changes, extracting insights, and identifying follow-up actions.Triggers: catchup, what changed, summarize changes, context acquisition, handoff,progress review, recent changes, git log analysis, sprint summaryUse when: resuming work after absence, preparing handoff documentation, reviewingsprint progress, analyzing git history for contextDO NOT use when: doing detailed diff analysis - use diff-analysis instead.DO NOT use when: full code review needed - use review-core instead.Use this skill to quickly understand "what changed and what matters".

Workflow for capturing evidence and citations to create reproducible analysesand audit trails.Triggers: evidence capture, citations, reproducible analysis, audit trail,documentation, evidence logging, findings documentationUse when: conducting any review that needs evidence trails, creating auditdocumentation, ensuring reproducibility of analysesDO NOT use when: quick informal checks without documentation needs.DO NOT use when: structured output is the focus - use structured-output.Use this skill as foundation for all evidence-based review workflows.

Development tooling standards including Deno runtime, JSR package registry, and configuration files. Use when setting up projects, managing dependencies, or configuring build tools.

Transform tool-heavy workflows into MCP code execution patterns for token savings and optimized processing.Triggers: MCP, code execution, tool chain, data pipeline, tool transformation, batch processing, workflow optimizationUse when: >3 tools chained sequentially, large datasets (>10k rows), large files (>50KB), context usage >25%DO NOT use when: simple tool calls that don't chain.DO NOT use when: context pressure is low and tools are fast.Use this skill BEFORE building complex tool chains. Optimize proactively.

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.

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。

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.

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 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.

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".

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.

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.

Use when user asks to leverage claude or claude code to do something (e.g. implement a feature design or review codes, etc). Provides non-interactive automation mode for hands-off task execution without approval prompts.

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.

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).

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