Generate Mermaid diagrams in markdown. Triggers on: diagrams, charts, visualizations, flowcharts, sequence diagrams, architecture diagrams, ER diagrams, state machines, Gantt charts, mindmaps, C4, class diagrams, git graphs. Use when: user asks for visual representations of code, systems, processes, data structures, database schemas, workflows, or API flows. Proactively suggest diagrams when explaining complex systems.
Provides comprehensive guidance for creating Mermaid diagrams. Mermaid is a JavaScript-based diagramming and charting tool that uses Markdown-inspired text definitions and a renderer to create and modify complex diagrams. The main purpose of Mermaid is to help documentation catch up with development. Mermaid is particularly well-suited for use in Markdown documents, GitHub, GitLab, wikis, blogs, and other Markdown-based platforms. Use when the user wants to draw, create, generate, make, build, or visualize any diagram, chart, graph, flowchart, architecture diagram, sequence diagram, class diagram, state diagram, Gantt chart, mindmap, timeline, or any other visual diagram in Markdown-friendly format. This skill covers all 23+ Mermaid diagram types including flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, Gantt charts, pie charts, quadrant charts, Git graphs, C4 diagrams, mindmaps, timelines, and more. Always use this skill when the user mentions Mermaid, needs diagrams for Markdown documentation, or wants quick diagrams that render directly in Markdown renderers.
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. Taken from https://github.com/anthropics/skills/blob/main/skills/brand-guidelines/SKILL.md
Expert blueprint for digital card games (CCG/Deckbuilders) including card data structures (Resource-based), deck management (draw/discard/reshuffle), turn logic, hand layout (arcing), drag-and-drop UI, effect resolution (Command pattern), and visual polish (godot-tweening, shaders). Use for CCG, deckbuilders, or tactical card games. Trigger keywords: card_game, deck_manager, card_data, hand_layout, drag_drop_cards, effect_resolution, command_pattern, draw_pile, discard_pile.
Safe experimentation framework for AI agents. Creates isolated sandbox environments for trying new features, testing approaches, and exploring solutions without polluting the main codebase. USE WHEN: Agent needs to try something uncertain, explore multiple approaches, test a new library, prototype a feature, or run a technical spike before committing to implementation. PRIMARY TRIGGERS: "experiment with" = Setup sandbox + run experiment "try this approach" = Quick experiment in sandbox "spike" / "POC" / "prototype" = Time-boxed technical investigation "tinker" / "tinkering mode" = Enter experimentation workflow "explore options" = Multi-approach comparison in sandbox NOT FOR: Debugging (use debugger), testing (use test runner), or committed feature work (use git branches). DIFFERENTIATOR: Unlike git branches (for committed direction), tinkering is for "I don't know if this will work" exploration. Try 5 things in sandbox before committing to a branch. Faster feedback, zero codebase pollution.
Interact with third-party services (Slack, Google Workspace, Dropbox, GitHub, Linear...) on the user's behalf using their public APIs.
Professional graphic design principles for digital and print media. Use when creating visual designs, choosing color palettes, typography, layouts, or providing design feedback.
Turn your marketing into an event that makes people beg to buy before you even release the product Use when: **Launching a new product or course** and want to maximize first-day sales; **Building anticipation** for an upcoming offer instead of "surprise" launching; **Growing your email list** while simultaneously warming them up to buy; **Creating urgency without being sleazy** with legitimate scarcity; **Turning skeptics into buyers** through sequenced value delivery
Conexión con herramientas externas via MCP: PostgreSQL, GitHub, Slack, Brave Search. Creación de MCP servers personalizados.
Technical safeguards and architectural patterns for building HIPAA-compliant software on AWS. Use when building healthcare SaaS, handling PHI (Protected Health Information), designing patient data systems, implementing healthcare APIs, setting up HIPAA-eligible AWS infrastructure, reviewing code for PHI exposure, designing audit logging, or when the user mentions patients, medical records, EHR/EMR, health data, HL7, FHIR, or covered entities. Essential for founders and developers building in healthcare or digital health space.
Meta-skill for extracting and creating reusable Claude Code skills from past work sessions. Analyzes git history, code patterns, workflows, and documentation to identify harvestable skills, then generates comprehensive skill definitions with best practices, examples, and structured templates.
Deep EVM smart contract security audit system. Use when asked to audit a contract, find vulnerabilities, review code for security issues, or file security issues on a GitHub repo. Covers 500+ non-obvious checklist items across 19 domains via parallel sub-agents. Different from the security skill (which teaches defensive coding) — this is for systematically auditing contracts you didn't write.
