anthropicsA growing collection of Claude-compatible academic workflow bundles. Covers scientific figures, manuscript writing and polishing, reviewer assessment, citation retrieval, data availability, paper reading, literature search, response letters, paper-to-PPTX conversion, and evidence-grounded Chinese invention patent drafting. Rules are organized as reusable skill folders with explicit workflows and quality checks.
Yuan1z0825Evidence-gated AI coding workflow: scan → analyze → plan → TDD → execute → fix → verify → review, powered by Codebase Memory MCP >= 0.9.0 with optional Serena LSP intelligence. Includes blast-radius planning, test/cycle gates, independent review, and Windows Git Bash hook auto-resolution.
datit309Browser automation and end-to-end testing MCP server by Microsoft. Enables Claude to interact with web pages, take screenshots, fill forms, click elements, and perform automated browser testing workflows.
anthropicsComprehensive feature development workflow with specialized agents for codebase exploration, architecture design, and quality review
anthropicsCore skills library for Claude Code: TDD, debugging, collaboration patterns, and proven techniques
obraUse this agent for analyzing test results, synthesizing test data, identifying trends, and generating quality metrics reports. This agent specializes in turning raw test data into actionable insights that drive quality improvements. Examples:\n\n<example>\nContext: Analyzing test suite results
SenSei2121Universal expert problem-solving agent specializing in complex debugging, mysterious runtime behavior, integration issues, and multi-layered technical challenges across any technology stack or project type. Uses advanced research methodologies including GitHub issues mining, Perplexity deep research, community solutions validation, browser automation testing, and multi-source documentation analysis. Proactively use for intricate bugs, cryptic error messages, performance anomalies, framework integration problems, legacy system compatibility issues, and any technical challenges requiring deep investigation across multiple knowledge sources. Project-agnostic and universally applicable.
SenSei2121Use this agent when you need to optimize B2B pricing strategies, packaging models, and revenue optimization for enterprise sales. This agent specializes in value-based pricing, usage-based billing, enterprise contract negotiations, and competitive pricing analysis for SaaS platforms. Examples:
SenSei2121Use this agent when you need to design, build, or validate n8n automation workflows. This agent specializes in creating efficient n8n workflows using proper validation techniques and MCP tools integration.\n\nExamples:\n- <example>\n Context: User wants to create a Slack notification workflow when a new GitHub issue is created.\n user: "I need to create an n8n workflow that sends a Slack message whenever a new GitHub issue is opened"\n assistant: "I'll use the n8n-workflow-builder agent to design and build this GitHub-to-Slack automation workflow with proper validation."\n <commentary>\n The user needs n8n workflow creation, so use the n8n-workflow-builder agent to handle the complete workflow design, validation, and deployment process.\n </commentary>\n</example>\n- <example>\n Context: User has an existing n8n workflow that needs debugging and optimization.\n user: "My n8n workflow keeps failing at the HTTP Request node, can you help me fix it?"\n assistant: "I'll use the n8n-workflow-builder agent to analyze and debug your workflow, focusing on the HTTP Request node configuration."\n <commentary>\n Since this involves n8n workflow troubleshooting and validation, use the n8n-workflow-builder agent to diagnose and fix the issue.\n </commentary>\n</example>\n- <example>\n Context: User wants to understand n8n best practices and available nodes for a specific use case.\n user: "What are the best n8n nodes for processing CSV data and sending email reports?"\n assistant: "I'll use the n8n-workflow-builder agent to explore the available nodes and recommend the best approach for CSV processing and email automation."\n <commentary>\n This requires n8n expertise and node discovery, so use the n8n-workflow-builder agent to provide comprehensive guidance.\n </commentary>\n</example>
