Extract vocals from audio files using Demucs with Apple GPU acceleration, and cut/trim audio to a specified duration. Use when the user asks to: (1) separate or extract vocals/voice from music, (2) remove vocals from a song, (3) cut or trim an audio file to a shorter length, (4) extract vocals AND trim them in one step. Handles MP3, WAV, and other common formats. Requires macOS with Apple Silicon (M-series) for GPU acceleration and the `uv` tool.

Take full-page screenshots of web pages using Playwright via a uv script. Use when the user asks to screenshot a URL for documentation, READMEs, or visual reports — whether live sites or local static HTML files.

Interact with local Chrome browser session (only on explicit user approval after being asked to inspect, debug, or interact with a page open in Chrome)

User-facing reference for Apple’s lightweight Linux container runtime `container`, which runs on Apple Silicon Macs. Covers everyday command usage including `container run`, `container build`, `container image pull/push`, `container machine`, volumes, networks, DNS, configuration files, and troubleshooting for the `container` command.

Write and edit in GOV.UK / GDS house style — plain English, active voice, front-loaded content, sentence case, and no bold or italics for emphasis. Use when writing or editing reports, research write-ups, guidance, documentation, summaries, or any prose where clarity and accessibility matter.

Browsing/scraping for sites with anti-bot protection (Cloudflare, Akamai, etc.) using CloakBrowser. Use whenever you need to access protected sites.

Generate an interactive PR review walkthrough as an HTML page. Fetches PR data via gh API, categorizes files into core vs mechanical changes, adds reviewer annotations, and renders diffs with moved-code detection. Use when the user pastes a GitHub PR URL and asks for a review, walkthrough, or summary, or says "review this PR".

Iterate on a PR until CI passes. Use when you need to fix CI failures, address review feedback, or continuously push fixes until all checks are green. Automates the feedback-fix-push-wait cycle.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Render inline interactive visuals — SVG diagrams, HTML widgets, charts, and explainers — directly in the conversation. Use this skill whenever the user asks to visualize, diagram, chart, illustrate, or explain something visually, or when an explanation would genuinely benefit from a spatial/interactive diagram rather than text. Also triggers for: flowcharts, architecture diagrams, data visualizations, interactive explainers, comparison layouts, UI mockups, and any request containing 'show me', 'draw', 'map out', 'visualize', or 'diagram'. Even when the user doesn't explicitly ask for a visual, use this skill proactively when the topic has spatial, sequential, or systemic relationships that a diagram would clarify better than prose.

Keep CLAUDE.md current after significant project changes. Use proactively when: (1) adding new modules, packages, or top-level directories, (2) changing build/test commands or tooling, (3) renaming/moving/deleting files referenced in CLAUDE.md, (4) introducing new conventions or patterns, (5) reorganizing document structure, (6) adding dependencies requiring setup steps. Invoke when user mentions CLAUDE.md, project docs update, or after completing architectural changes.

Generate beautiful, self-contained HTML pages that visually explain systems, code changes, plans, and data. Use when the user asks for a diagram, architecture overview, diff review, plan review, project recap, comparison table, or any visual explanation of technical concepts. Also use proactively when you are about to render a complex ASCII table (4+ rows or 3+ columns) — present it as a styled HTML page instead.

Operate Docker Sandboxes for AI coding agents to choose and run agents, configure credentials, reuse named sandboxes, mount multiple workspaces, apply network policies, use custom templates, troubleshoot failures, and migrate legacy setups. Use when requests involve docker sandbox commands, sandbox isolation behavior, supported agents (claude, codex, copilot, gemini, cagent, kiro, opencode, shell), or Docker Sandbox setup/debugging on macOS or Windows.

Create stunning, animation-rich HTML presentations from scratch or by converting PowerPoint files. Use when the user wants to build a presentation, convert a PPT/PPTX to web, or create slides for a talk/pitch. Helps non-designers discover their aesthetic through visual exploration rather than abstract choices.

PR review mode skill. Use this skill when the user wants to run in pull request review mode, automatically respond to GitHub PR review comments, have an AI agent monitor open GitHub pull requests and address feedback, run preemptive code reviews on new GitHub PRs, or replicate the --pull-request-mode workflow using Agent natively. Trigger on phrases like "PR review mode", "monitor pull requests", "address review comments automatically", "preemptive PR review".

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Agent's capabilities with specialized knowledge, workflows, or tool integrations.

Adversarial requirements engineering skill that compiles ambiguous feature requests into a validated JSON spec, then instructs the LLM to generate context-appropriate artifacts in the target repository's native stack. Use when users ask to define, clarify, or formalize software requirements before implementation.

Create distinctive, production-grade SwiftUI interfaces with high design quality for Apple platforms. Use this skill when the user asks to build iOS, iPadOS, macOS, watchOS, or tvOS interfaces. Generates creative, polished code that follows Apple Human Interface Guidelines.

Ticket mode skill. Use this skill when the user wants to run in ticket mode, automate JIRA-to-GitHub-PR workflows, implement JIRA tickets automatically, poll JIRA for ready issues and create GitHub pull requests, or replicate the ticket automation workflow using Agent natively. Trigger on phrases like "run ticket mode", "automate issues", "issue to PR", "implement tickets automatically".
