Provides 100+ production-ready agent implementations across three primary frameworks (Agno, LangChain/LangGraph, and native Python) organized by complexity tier (starter, advanced single-agent, multi-agent). Each implementation includes complete dependency specifications, environment configuration templates, and runnable entry points, allowing developers to clone and immediately execute agents without framework-specific boilerplate. The repository uses a tiered complexity model where starter agents demonstrate basic tool-calling patterns, advanced agents implement planner-executor architectures with state management, and multi-agent systems showcase coordination via message passing or shared context.
Unique: Organizes 100+ implementations across three distinct frameworks (Agno, LangChain/LangGraph, native) with explicit complexity tiers (starter/advanced/expert) and domain-specific examples (finance, travel, research), enabling side-by-side framework comparison and progressive learning paths. Most agent repositories focus on a single framework; this one treats framework diversity as a feature.
vs alternatives: Broader framework coverage and clearer complexity progression than single-framework tutorials; more production-focused than academic agent papers but less opinionated than framework-specific docs
Implements 8+ distinct RAG architectures (basic retrieval, corrective RAG, hybrid retrieval, database routing, agentic RAG, autonomous RAG, RAG with reasoning) with working code for each pattern. Each implementation demonstrates a specific retrieval strategy: basic RAG uses vector similarity search, corrective RAG adds a grading step to filter irrelevant chunks, hybrid RAG combines vector and keyword search, database routing uses an LLM to select which database to query, and agentic RAG treats retrieval as a tool the agent can invoke iteratively. Implementations support multiple vector databases (Pinecone, Weaviate, Chroma, FAISS) and document sources (PDFs, web pages, databases, code repositories).
Unique: Provides 8+ distinct RAG patterns (basic, corrective, hybrid, database routing, agentic, autonomous, reasoning-enhanced) with working implementations for each, allowing developers to compare trade-offs between retrieval quality and latency. Most RAG tutorials show only basic vector search; this library treats RAG as a design space with multiple valid solutions.
vs alternatives: More comprehensive RAG pattern coverage than LangChain's built-in RAG examples; more practical than academic RAG papers with runnable code for each pattern
Implements specialized agents for financial analysis and investment decisions that integrate real-time market data, financial APIs, and domain-specific reasoning. The investment agent can fetch stock prices, analyze financial statements, calculate metrics (P/E ratio, dividend yield), and provide investment recommendations. Integration with financial data providers (Alpha Vantage, Finnhub, or similar) enables real-time market data access. The agent uses domain-specific prompts and reasoning patterns for financial analysis, handles numerical precision and currency conversions, and provides citations to data sources. Examples include portfolio analysis agents, stock recommendation agents, and market trend analysis agents.
Unique: Provides investment agent implementations with real-time market data integration, financial metric calculations, and domain-specific reasoning patterns. Demonstrates how to handle numerical precision, currency conversions, and financial data sources. Most agent tutorials are generic; this library includes domain-specific agents for finance.
vs alternatives: More specialized than generic agents but less comprehensive than dedicated financial analysis platforms; useful for prototyping financial agents
Implements agents that can browse the web, scrape content, and extract information from dynamic websites using browser automation (Selenium, Playwright, or Puppeteer). The web scraping agent can navigate websites, interact with forms and buttons, wait for dynamic content to load, and extract structured data. Integration with agent frameworks allows the agent to decide what to scrape, how to navigate, and how to extract information based on user requests. Examples include competitive intelligence agents that scrape competitor websites, price monitoring agents that track product prices, and content aggregation agents that gather information from multiple sources. The agent handles JavaScript-heavy sites and can wait for content to load before extraction.
Unique: Provides web scraping agent implementations with browser automation, dynamic content handling, and integration with agent frameworks. Demonstrates how agents can decide what to scrape and how to navigate websites. Most agent tutorials don't include web scraping; this library treats it as a legitimate agent capability with appropriate caveats.
vs alternatives: More practical than generic scraping tutorials; enables agent-driven scraping but with significant latency and resource trade-offs vs direct HTTP scraping
Implements advanced RAG patterns that improve retrieval quality beyond basic vector similarity search. Corrective RAG adds a grading step where an LLM evaluates whether retrieved documents are relevant to the query; if not, the system reformulates the query and retrieves again. Hybrid RAG combines multiple retrieval strategies (vector similarity, keyword search, semantic search) and ranks results by combining scores from different methods. Implementations demonstrate how to define relevance criteria, implement grading logic, and combine retrieval scores. The corrective approach trades latency for quality (additional LLM calls), while hybrid approaches balance different retrieval strengths.
Unique: Provides implementations of corrective RAG (with relevance grading and query reformulation) and hybrid RAG (combining vector and keyword search) with explicit trade-offs between quality and latency. Demonstrates how to define and implement relevance criteria. Most RAG tutorials show only basic vector search; this library treats quality improvement as a design pattern.
vs alternatives: More sophisticated than basic RAG but with documented latency costs; more practical than academic RAG papers with working code
Demonstrates MCP protocol integration for agents that need to interact with external systems (GitHub, Notion, browsers, file systems) through standardized tool schemas. Implementations show how to define MCP tool specifications (input schemas, descriptions), bind them to agent frameworks (Agno, LangChain), and handle tool execution with error recovery. The repository includes examples of travel planning agents using MCP for flight/hotel APIs, GitHub agents using MCP for repository operations, and browser automation agents using MCP for web scraping, all following the MCP specification for tool discovery and invocation.
Unique: Provides working MCP implementations for diverse use cases (travel planning, GitHub operations, browser automation, Notion integration) with explicit tool schema definitions and error handling patterns. Demonstrates how MCP standardizes tool discovery and invocation across different external systems, reducing boilerplate compared to custom API wrappers.
vs alternatives: More comprehensive MCP examples than official MCP documentation; more standardized than custom tool-calling implementations but less mature than framework-specific tool ecosystems
Implements multi-agent systems where specialized agents (e.g., SEO auditor, content writer, technical reviewer) coordinate via message passing or shared state to solve complex tasks. Examples include an SEO audit team where one agent crawls websites, another analyzes content, and a third generates recommendations; a home renovation agent where one agent gathers requirements, another estimates costs, and a third creates project plans. Coordination patterns include sequential task handoff (agent A completes, passes results to agent B), parallel execution with result aggregation, and hierarchical delegation (manager agent assigns tasks to worker agents). Implementations use either explicit message queues or shared context objects to pass information between agents.
Unique: Provides concrete multi-agent examples (SEO audit team, home renovation agent) with explicit coordination patterns (message passing, shared context, hierarchical delegation) and implementation code. Most agent tutorials focus on single agents; this library treats multi-agent coordination as a first-class pattern with multiple architectural approaches.
vs alternatives: More practical multi-agent examples than academic papers; more detailed than framework docs but less opinionated than specialized multi-agent frameworks like AutoGen
Implements research agents that decompose complex research queries into sub-questions, search the web for relevant information, synthesize findings, and iteratively refine results. The research agent uses a planner-executor pattern: a planner LLM breaks down 'research X' into specific search queries, an executor searches the web and retrieves documents, and a synthesizer combines results into a coherent report. Integration with Google Gemini Interactions API enables real-time web search within agent reasoning loops. The agent can iterate — if initial results are insufficient, it generates follow-up queries and searches again. Outputs include structured research reports with source citations and confidence scores.
Unique: Combines planner-executor-synthesizer architecture with iterative refinement and real-time web search via Gemini Interactions API, enabling agents to conduct research beyond their training data. Most research agents use static RAG; this implementation treats web search as a first-class agent capability with iterative improvement.
vs alternatives: More sophisticated than basic web search agents; tightly integrated with Gemini's native search capabilities but less portable than framework-agnostic approaches

LangChain provides a Chain abstraction that sequences LLM calls, prompt templates, and tool invocations into directed acyclic graphs (DAGs). Chains support sequential execution (SequentialChain), conditional branching (RouterChain), and parallel execution patterns. The framework uses a Runnable interface that standardizes input/output contracts across all chain components, enabling composition via pipe operators and method chaining. This allows developers to build complex multi-step workflows without managing state manually.
Unique: Uses a unified Runnable interface across all components (LLMs, tools, retrievers, parsers) enabling composability via pipe operators, unlike frameworks that require separate orchestration layers for different component types. Supports both sync and async execution with identical code paths.
vs alternatives: More flexible than simple prompt chaining (like OpenAI's function calling alone) because it abstracts orchestration logic, making chains reusable and testable; simpler than full workflow engines (Airflow, Prefect) because it's optimized for LLM-specific patterns rather than general data pipelines.
LangChain's PromptTemplate class provides structured prompt engineering with variable placeholders, automatic validation, and support for few-shot learning patterns. Templates use Jinja2-style syntax for variable substitution and support dynamic example selection via ExampleSelector. The framework includes specialized templates (ChatPromptTemplate for multi-turn conversations, FewShotPromptTemplate for in-context learning) that handle formatting differences across LLM types. This enables prompt reusability, version control, and systematic experimentation without string concatenation.
Unique: Provides first-class abstractions for few-shot learning (FewShotPromptTemplate) with pluggable ExampleSelector strategies, enabling dynamic example selection based on input similarity without requiring developers to implement selection logic. Separates system prompts, conversation history, and user input in ChatPromptTemplate, making multi-turn conversations composable.

vs alternatives: More structured than manual string formatting because it validates variable names and supports semantic example selection; more specialized than generic templating engines (Jinja2) because it understands LLM-specific patterns like chat message roles and few-shot formatting.
LangChain abstracts function calling across LLM providers by converting Python functions or Pydantic models into provider-specific schemas (OpenAI function_call, Anthropic tool_use, etc.). The framework automatically generates schemas, handles argument parsing, and routes calls to the correct provider. Developers define functions once and LangChain handles provider-specific formatting. This enables tool use without learning each provider's function calling API.
Unique: Automatically converts Python functions and Pydantic models into provider-specific function calling schemas (OpenAI, Anthropic, Cohere, etc.) and handles parsing and routing transparently. Developers define tools once and LangChain handles provider-specific formatting and execution.
vs alternatives: More portable than using provider SDKs directly because function definitions are provider-agnostic; more automated than manual schema management because schemas are generated from function signatures.
LangChain supports streaming LLM output at token granularity, enabling real-time user feedback as tokens are generated. The framework provides streaming iterators and async generators that yield tokens as they arrive from the LLM. Streaming is integrated into chains and agents, so developers can stream output from complex workflows without special handling. This enables responsive user experiences where output appears in real-time rather than waiting for full completion.
Unique: Integrates streaming at the framework level so chains and agents can stream output transparently without special handling. Provides both sync and async streaming iterators and handles provider-specific streaming formats uniformly.
vs alternatives: More integrated than provider-specific streaming APIs because streaming works across chains and agents; more responsive than buffering full output because tokens appear in real-time.
LangChain provides async/await support throughout the framework, enabling concurrent execution of LLM calls, chains, and agents. All major components (LLMs, chains, retrievers, agents) have async variants (e.g., arun() alongside run()). The framework uses asyncio for Python and native async/await for Node.js. This enables high-concurrency applications that can handle multiple requests simultaneously without blocking. Async execution is transparent; developers write the same code as sync but use async/await syntax.
Unique: Provides async/await support throughout the framework with parallel async implementations of all major components. Enables transparent concurrent execution without requiring developers to manage thread pools or explicit parallelization.
vs alternatives: More integrated than manual async management because async is built into the framework; more scalable than sync-only implementations because it enables handling multiple concurrent requests.
LangChain abstracts LLM APIs behind a common BaseLanguageModel interface, supporting OpenAI, Anthropic, Cohere, Hugging Face, Ollama, and 20+ other providers. The abstraction handles provider-specific details: token counting, streaming, function calling schemas, and cost tracking. Developers write LLM-agnostic code and swap providers via configuration. The framework includes built-in retry logic, rate limiting, and fallback chains for reliability. This enables portability and cost optimization without rewriting application logic.
Unique: Implements a unified BaseLanguageModel interface that abstracts away provider differences in token counting, streaming protocols, and function calling schemas. Includes built-in retry policies, rate limiting, and cost tracking at the framework level rather than requiring developers to implement these separately for each provider.
vs alternatives: More portable than using provider SDKs directly because swapping providers requires only configuration changes; more comprehensive than simple wrapper libraries because it handles streaming, retries, and cost tracking uniformly across 20+ providers.
LangChain provides a Retriever abstraction that enables RAG by connecting LLMs to external knowledge sources. The framework supports multiple retrieval strategies: vector similarity search (via VectorStore), BM25 keyword search, hybrid search, and custom retrievers. Documents are chunked, embedded, and stored in vector databases (Pinecone, Weaviate, Chroma, FAISS, etc.). The RetrievalQA chain automatically retrieves relevant documents and passes them as context to the LLM. This enables LLMs to answer questions grounded in custom data without fine-tuning.
Unique: Provides a unified Retriever interface that abstracts different retrieval strategies (vector, keyword, hybrid, custom) and integrates seamlessly with LLM chains via RetrievalQA. Includes built-in document loaders for 50+ formats (PDF, HTML, Markdown, code files) and automatic chunking strategies, reducing boilerplate for document ingestion.
vs alternatives: More integrated than building RAG from scratch because document loading, chunking, embedding, and retrieval are unified in one framework; more flexible than specialized RAG platforms (Pinecone, Weaviate) because it supports multiple vector stores and custom retrieval logic.
LangChain's Agent abstraction enables autonomous task execution by combining LLMs with tools (functions, APIs, retrievers). The agent uses an action-observation loop: the LLM decides which tool to call based on the task, executes the tool, observes the result, and repeats until the task is complete. Agents support multiple reasoning strategies: ReAct (reasoning + acting), chain-of-thought, and tool-use patterns. The framework handles tool schema generation, argument parsing, and error recovery. This enables building autonomous systems that can decompose complex tasks without explicit step-by-step instructions.
Unique: Implements a generalized Agent interface that supports multiple reasoning strategies (ReAct, chain-of-thought, tool-use) and automatically handles tool schema generation, argument parsing, and error recovery. The action-observation loop is abstracted, allowing developers to focus on defining tools rather than implementing agent logic.
vs alternatives: More flexible than simple function calling (OpenAI's tool_choice) because it implements multi-step reasoning and tool sequencing; more accessible than building agents from scratch because it handles schema generation, parsing, and error recovery automatically.
