santa-method is a multi-agent verification workflow for outputs that need to be right before they ship. It uses independent review to catch blind spots in content, code-adjacent deliverables, compliance-sensitive copy, and workflow automation tasks. Install the santa-method skill when you need a repeatable generate, verify, converge loop.

lead-intelligence is an AI lead intelligence workflow for Lead Research, scoring prospects, finding warm paths, and drafting outreach. Use the lead-intelligence skill to build a ranked lead list, assess fit, and turn research into email, LinkedIn, or X outreach with less guesswork.

gan-style-harness is a Generator-Evaluator skill for Agent Orchestration that helps build complete apps with stricter critique, better iteration, and fewer weak spots. Use it when you need the gan-style-harness skill for frontend-heavy, full-stack, or production-minded work where review quality matters more than speed.

claude-api helps with Anthropic Claude API patterns for Python and TypeScript, including install, messages, streaming, tool use, vision, batches, prompt caching, model selection, and Claude Agent SDK workflows.

autonomous-agent-harness turns Claude Code into a persistent, self-directing agent system with memory, scheduled runs, task dispatch, and computer use. It fits agent orchestration, recurring checks, and long-lived workflows when you need more than a one-time prompt.

writing-skills is a Skill Authoring guide for creating, editing, and validating agent skills with a test-driven workflow. Learn the key files, prerequisites, and practical steps for pressure scenarios, baseline tests, and concise SKILL.md iteration.

skill-creator is a Skill Authoring meta-skill for drafting new skills, revising existing SKILL.md files, running evals, comparing variants, and improving trigger descriptions with repository scripts and review tools.

webapp-testing is a skill for testing local web apps with Python Playwright. It helps agents start servers with scripts/with_server.py, inspect rendered UI, discover selectors, capture screenshots and console logs, and validate frontend behavior with a reconnaissance-first workflow.

theme-factory is a curated theming skill for slides, docs, reports, and landing pages. Review the showcase, choose from 10 preset themes, then apply consistent colors and font pairings to your artifact.

Use the pptx skill to read, create, edit, split, merge, and inspect PowerPoint .pptx files. It guides you through text extraction with markitdown, thumbnail review, unpack/edit/clean/pack workflows, and PptxGenJS for new deck creation.

mcp-builder is a practical guide for planning, building, and evaluating MCP servers for external APIs and services. It helps developers choose tool scope, naming, transport, Python or Node implementation patterns, and evaluation workflows so agents can use the server reliably.

The internal-comms skill helps write internal company communications like 3P updates, newsletters, FAQs, status reports, and leadership updates using example-driven formats from the Anthropic skills repository.

doc-coauthoring is a structured workflow for drafting docs with AI through context gathering, iterative outlining, section-by-section writing, and reader testing for review-ready specs, RFCs, and proposals.

claude-api is a practical skill for installing and using the Claude API and Anthropic SDKs. It helps developers choose the right SDK or raw HTTP path, detect language-specific docs, and implement streaming, tool use, files, batches, and error handling with less guesswork.

canvas-design helps create original static visual work through a two-step flow: write a design philosophy in Markdown, then render it as a .png or .pdf. Best for posters, cover art, concept visuals, and UI-adjacent campaign graphics with minimal text.

brand-guidelines gives agents Anthropic brand colors and typography for restyling docs, slides, HTML, and other text-led artifacts. Use it to apply consistent on-brand formatting, font hierarchy, and palette choices after content is drafted.

algorithmic-art helps create original generative art in p5.js with a two-step workflow: write an algorithmic philosophy, then build runnable .html and .js outputs with seeded randomness, parameter controls, and an interactive viewer.

cso is a Chief Security Officer–style security audit skill for agents. It helps review codebases and workflows for secrets exposure, dependency and supply-chain risk, CI/CD security, and LLM/AI security using OWASP Top 10 and STRIDE. Use cso for structured Security Audit reviews with confidence gates, active verification, and trend tracking.

embedding-strategies helps you choose and optimize embedding models for semantic search and RAG workflows, with practical guidance on chunking, model tradeoffs, multilingual content, and retrieval evaluation.

develop-ai-functions-example helps you create or modify runnable AI SDK examples in vercel/ai under examples/ai-functions/src/. Use it to choose the right category, match repo conventions, and build minimal examples for provider validation, demos, or fixtures.

The context-engineering skill helps you structure project context so agents follow conventions, reduce hallucinations, and stay focused. Use it when starting a session, switching tasks, or building a context-engineering guide for a codebase.

browser-testing-with-devtools helps agents test and debug real browser behavior through Chrome DevTools MCP. Use it to inspect the DOM, capture console errors, analyze network requests, profile performance, and verify fixes in a live browser.

git-guardrails-claude-code adds a Claude Code PreToolUse hook that blocks dangerous Git commands like push, reset --hard, clean -f, branch -D, checkout ., and restore . before execution. It supports project or global install, manual hook setup, executable script permissions, and behavior testing with the bundled shell script.

aihot is a web-research skill for current AI news, daily picks, model launches, and trend summaries from aihot.virxact.com. Use the aihot skill when you need fresh AI updates in Chinese or English, including today’s headlines, recent releases, and concise briefing-style summaries without relying on stale training data.
