LLM & Agents

Install agent docs without overwriting or deleting existing content.

Write clear, effective technical documentation following industry-proven patterns from exemplary projects and authoritative style guides, with built-in countermeasures for common LLM documentation issues

Automatically detects, installs, and configures Language Server Protocol (LSP) servers for enhanced code intelligence. Provides go-to-definition, find-references, hover docs, and symbol navigation.TRIGGERS - Keywords: lsp, language server, code intelligence, go to definition, find references, hover, symbols, diagnostics, autocomplete, intellisense, code navigation, jump to definition, find usages, type info.TRIGGERS - Phrases: "set up lsp", "install language server", "enable code intelligence", "configure lsp", "go to definition not working", "find references", "show type", "navigate to symbol", "code navigation".TRIGGERS - Automatic: After tech-detection completes, when opening new file types, when LSP operations fail.

Use this skill when building MCP (Model Context Protocol) servers with FastMCP in Python. FastMCP is a framework for creating servers that expose tools, resources, and prompts to LLMs like Claude. The skill covers server creation, tool/resource definitions, storage backends (memory/disk/Redis/DynamoDB), server lifespans, middleware system (8 built-in types), server composition (import/mount), OAuth Proxy, authentication patterns, icons, OpenAPI integration, client configuration, cloud deployment (FastMCP Cloud), error handling, and production patterns. It prevents 25+ common errors including storage misconfiguration, lifespan issues, middleware order errors, circular imports, module-level server issues, async/await confusion, OAuth security vulnerabilities, and cloud deployment failures. Includes templates for basic servers, storage backends, middleware, server composition, OAuth proxy, API integrations, testing, and self-contained production architectures.

Add a new tool to the backend OpenAI function calling system. Use when user mentions "new tool", "add tool", "backend function", "agent capability", or wants to extend what the AI agent can do.

Guides npm package maintenance tasks. Use when user mentions outdated packages, npm audit, security vulnerabilities, dependency updates, package optimization, unused dependencies, or devDependencies categorization. Recommends the npm-package-maintainer agent via /maintain commands.

Master MongoDB schema design and data modeling patterns. Learn embedding vs referencing, relationships, normalization, and schema evolution. Use when designing databases, normalizing data, or optimizing queries.

specialized agent for writing high-quality, educational technical content for Docusaurus books. Focuses on clarity, engagement, and technical accuracy using modern documentation standards.

Creates Claude Code skills where each skill is tied to a specialist agent optimized with evidence-based prompting techniques. Use this skill when users need to create reusable skills that leverage specialized agents for consistent high-quality performance. The skill ensures that each created skill spawns an appropriately crafted agent that communicates effectively with the parent Claude Code instance using best practices.

Creates complete PowerPoint presentations from a topic or brief. Generates slide structure, compelling content, speaker notes, and image suggestions/prompts. Use when you need to create business presentations, pitch decks, educational slides, or any visual presentation quickly.

Upload images to Imgur for free hosting. Use this skill when you need to upload images and get public URLs for sharing or embedding in articles.

Autonomous web research for presentation topics using Claude Agent SDK. Conducts multi-step research, extracts insights, and manages citations.

This skill should be used when parallelizing multi-issue sprints using git worktrees and parallel Claude agents. Use when tackling multiple GitHub issues simultaneously, when the user mentions "blitz", "parallel sprint", "worktree workflow", or when handling 3+ independent issues that could be worked on concurrently. Orchestrates the full workflow from issue triage through parallel agent delegation to sequential merge.
