Auto-load when user says "strategy memo", "pre-read", "6-pager", "director briefing", "leadership document", "data-backed narrative", or "strategy document".
theme-factory
Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.
web-artifacts-builder
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
webapp-testing
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
xlsx-python
Create and edit spreadsheets with Python (openpyxl/xlsxwriter) for formulas, formatting, data analysis, and visualization. Use when you need to CREATE or MODIFY spreadsheets programmatically. For READING/ANALYZING existing spreadsheets, prefer the xlsx CLI skill.
xlsx
Use xlsx binary for Excel file manipulation including viewing, SQL-like filtering, cell editing, conversion to/from CSV, and data analysis operations.
xsv
Use xsv for fast CSV data processing with selection, filtering, statistics, joining, sorting, and indexing for high-performance data manipulation.
brand-guidelines
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
canvas-design
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
claude-cli
Use claude CLI for interactive AI sessions, scripting with print mode, MCP server management, and plugin configuration. Master session management, tool control, and automation workflows.
claude-tail
View Claude Code session logs with colors, filtering, and real-time following
conform
Transform unstructured data into structured JSON using AI-powered extraction. Use when extracting structured data from text/PDFs/CSVs, parsing unstructured content, converting to schema-compliant JSON, or validating data structures. Triggers on "extract data", "parse unstructured", "convert to JSON", "structure data", "schema validation", or AI-based data transformation tasks.
doc-coauthoring
Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
docx

epist
Epistemological tracking system for managing facts, conclusions, and provenance chains with Git integrity and semantic search. Integrates with Quarto for visual provenance analysis. Use when analyzing data from multiple sources, conducting research, working with metrics/surveys, making data-driven conclusions, or tracking complex findings. Triggers on data analysis (analyze data, metrics, survey, research, findings, insights), conclusions (conclude, recommend, decide, infer), quantitative work (percentage, trend, correlation, statistic), source attribution (according to, based on, from source), or any epistemological tracking. Skip for trivial calculations.
frontend-design
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 (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
