Produces focused instructions, documentation, deterministic tests, Vally evals, locked tooling, registration, and optional validated thumbnail art\\. USE FOR: create-skill, create a skill, add an agent skill, scaffold a portable skill, register a skill, add skill to managed repo, create skill in existing repo, generate an example skill from a fixture, add skill thumbnail art\\. DO NOT USE FOR: scaffolding a new marketplace collection from scratch \\(use create-skills-repo\\), editing one existing skill instruction without registration work \\(use skill-authoring\\), creating an agent persona\\. |\n| [`csv-analysis`](skills/csv-analysis/) | \\*\\*WORKFLOW SKILL\\*\\* - Analyze CSV files and generate statistical data quality reports\\. USE FOR: analyze CSV files, profile tabular data, inspect CSV quality, generate CSV reports\\. DO NOT USE FOR: editing spreadsheets or producing XLSX workbooks; use spreadsheet tooling instead\\. |\n| [`drawio-diagrams`](skills/drawio-diagrams/) | \\*\\*WORKFLOW SKILL\\*\\* - Create, validate, and edit accessible draw\\.io SVG diagrams that remain visually editable\\. Supports basic flowchart and architecture shapes, semantic styling, orthogonal connectors, strict specification validation, and embedded mxGraph XML\\. USE FOR: create a draw\\.io diagram, create a \\.drawio\\.svg, make an editable architecture or flow diagram, validate draw\\.io XML, use diagrams\\.net\\. DO NOT USE FOR: quick throwaway diagrams that do not need draw\\.io editability; use Mermaid instead, or complex cloud/UML diagrams that require full draw\\.io shape libraries; use draw\\.io Desktop or jgraph/drawio-mcp\\. |\n| [`marp-authoring`](skills/marp-authoring/) | \\*\\*WORKFLOW SKILL\\*\\* - Create and revise Marp decks with reliable slide structure, content transformations, speaker notes, layouts, and existing theme styles\\. USE FOR: create Marp slides, add a slide, rewrite slide content, split or merge slides, reorder a deck, add speaker notes, apply slide layouts, restyle slides\\. DO NOT USE FOR: generating chart or diagram assets; use marp-visuals, or reviewing overflow and rendering; use marp-slide-review\\. |\n| [`marp-slide-review`](skills/marp-slide-review/) | \\*\\*WORKFLOW SKILL\\*\\* - Review rendered Marp slide decks for overflow, clipping, visual balance, asset failures, and HTML/PDF rendering differences\\. USE FOR: review Marp slides, check slide overflow, inspect rendered slides, lint a deck layout, verify slides fit, compare PDF rendering\\. DO NOT USE FOR: authoring slide content; use marp-authoring, or generating chart and diagram assets; use marp-visuals\\. |\n| [`marp-visuals`](skills/marp-visuals/) | \\*\\*WORKFLOW SKILL\\*\\* - Create deterministic charts, Mermaid diagrams, graphs, and accessible static visual assets for Marp decks\\. USE FOR: add a chart to slides, build a graph, create a Mermaid diagram, turn data into a slide visual, generate SVG assets for Marp\\. DO NOT USE FOR: editing slide narrative or layout; use marp-authoring, or creating diagrams that must remain editable in draw\\.io; use drawio-diagrams\\. |\n| [`pptx-to-marp-theme`](skills/pptx-to-marp-theme/) | \\*\\*WORKFLOW SKILL\\*\\* - Extract brand colors, font families, logos, images, and slide dimensions from PowerPoint templates, generate a Marp CSS theme, and safely apply it to existing decks\\. USE FOR: convert a PowerPoint template to a Marp theme, extract PPTX or POTX branding, extract colors fonts logos and images, apply a PowerPoint-derived theme to existing Marp slides\\. DO NOT USE FOR: editing PowerPoint slide content; use PPTX tooling, or rewriting Marp slide narrative; use marp-authoring\\. |\n\n## Install\n\nList or install skills with the portable skills installer:\n\n```sh\nnpx skills add https://github.com/codebytes/skills --list\nnpx skills add https://github.com/codebytes/skills --all\n```\n\nInstall the complete Agent Plugins package:\n\n```sh\ncopilot plugin install https://github.com/codebytes/skills\n```\n\n## Supported agents\n\nThe canonical content lives in `skills/`.
