Use when the user asks to create, publish, deploy, update, or maintain a Cowork marketplace - a public GitHub repo with a .agents/plugins/marketplace.json catalog that distributes plugins and standalone skills, versioned by per-entry sourceHash fingerprints. Triggers on: 'create a marketplace', 'publish a marketplace', 'deploy a marketplace', 'set up a marketplace repo', 'add a plugin to my marketplace', 'add a skill to my marketplace', 'update marketplace hashes', 'marketplace source hash mismatch'.

Create, edit, redline, and comment on `.docx` files inside the container, with a strict render-and-verify workflow. Use `render_docx.py` to generate page PNGs (and optional PDF) for visual QA, then iterate until layout is flawless before delivering the final DOCX.

Read, create, inspect, render, and verify PDF files where visual layout matters. Use Poppler rendering plus Python tools such as reportlab, pdfplumber, and pypdf for generation and extraction.

Build premium editorial analytics PPTX decks with artifact-tool presentation JSX, using ruthless narrative editing, chart-first storytelling, rendered critique, and iteration until the output beats the reference deck.

Use when the user asks to create, author, scaffold, package, edit, or update a plugin — a bundle with a .cowork-plugin/plugin.json manifest that groups one or more skills and, optionally, MCP servers and app integrations. Triggers on: 'create a plugin', 'new plugin', 'author a plugin', 'edit a plugin', 'update a plugin', 'add a skill to a plugin', 'bundle these skills into a plugin', 'make a plugin.json', 'add an MCP server to a plugin'.

Use when the user asks to create, author, scaffold, write, or improve a skill — a SKILL.md package that gives an agent specialized, on-demand instructions plus optional bundled resources. Triggers on: 'create a skill', 'new skill', 'write a skill', 'author a skill', 'add a skill', 'scaffold a skill', 'make a SKILL.md', 'improve this skill', 'fix my skill description'.

Transcribe local audio files on macOS 26 or newer with the `apple-native-transcribe` CLI. Use when a task needs Apple's on-device SpeechAnalyzer and SpeechTranscriber workflow for `.mp3`, `.m4a`, `.wav`, or similar local audio, and the CLI may need to be verified or installed with `brew install mweinbach/max-skills/apple-native-transcribe`. Do not use this skill on Linux, Windows, or macOS versions earlier than 26.

Use this skill when a user requests to create, modify, analyze, visualize, or work with spreadsheet files (`.xlsx`, `.xls`, `.csv`, `.tsv`) with formulas, formatting, charts, tables, and recalculation.
