Proposed by aparekh02Description: This PR introduces the CoT (Chain-of-Thought) Agent, a sophisticated reasoning system that models reasoning as an explicit latent sequence of reasoning tokens between input and output. The agent implements step-by-step reasoning with support for self-consistency, quantum-inspired sampling, and statistical mechanics-based trace selection. Issue: N/A (New Feature) Dependencies: - loguru (for logging) - Standard library: dataclasses, typing, enum, re, collections, math, random Tag maintainer: @kyegomez ================================================================================ WHAT IS THE COT AGENT? ================================================================================ The CoT Agent is a sequential reasoning system that performs: 1. REASONING TRACE GENERATION: Creates step-by-step reasoning sequences 2. MULTIPLE DECODING STRATEGIES: Greedy, sampling, nucleus, and quantum 3. SELF-CONSISTENCY: Aggregates multiple reasoning traces for robust answers 4. TRACE EVALUATION: Scores reasoning quality using heuristics or learned models 5. ANSWER EXTRACTION: Decodes final answers from reasoning traces 6. QUANTUM SUPERPOSITION: Implements quantum-inspired trace measurement Unlike direct answer generation, CoT enables: - Explicit reasoning steps that can be verified - Self-consistency through multiple traces - Uncertainty quantification via entropy - Trace quality assessment - Explainable reasoning processes ================================================================================ HOW IT REVOLUTIONIZES REASONING ================================================================================ EXPLICIT REASONING PROCESS: Traditional LLM inference produces answers directly. CoT makes reasoning explicit: - Step 1: Break down problem - Step 2: Identify key components - Step 3: Apply relevant principles - Step 4: Perform calculations - Step 5: Synthesize answer This enables: - Verification of reasoning steps - Identification of errors in reasoning - Explanation of answer derivation - Learning from reasoning traces Example: Mathematical problem solving - Step 1: "I need to find the average speed" - Step 2: "Average speed = total distance / total time" - Step 3: "Distance = 120 miles, Time = 2 hours" - Step 4: "Average speed = 120 / 2 = 60 miles per hour" - Answer: "60 miles per hour" SELF-CONSISTENCY FOR ROBUSTNESS: CoT generates multiple reasoning traces and aggregates answers: - Trace 1: Uses algebraic approach → Answer A - Trace 2: Uses geometric approach → Answer A - Trace 3: Uses numerical approach → Answer B - Aggregation: Majority voting → Answer A (confidence: 0.67) This provides: - Robustness to reasoning errors - Confidence estimation - Multiple perspectives on problem - Error detection through inconsistency QUANTUM-INSPIRED SAMPLING: CoT implements quantum superposition of reasoning paths: |ψ⟩ = Σ_{r} α_r |r⟩ ⊗ |y_r⟩ Where α_r = √(p_θ(r | x)) is the amplitude for reasoning trace r. Measurement probability: P(y | x) = |⟨y | ψ⟩|² = |Σ_{r: y_r=y} α_r|² This enables: - Probabilistic answer selection - Amplitude-based weighting - Superposition of reasoning states - Quantum measurement semantics STATISTICAL MECHANICS: CoT models reasoning traces using energy functions: E(r, x) = -log p_θ(r | x) Boltzmann distribution: p_θ(r | x) = (1/Z(x)) exp(-E_θ(r, x) / T) This enables: - Temperature-controlled exploration - Energy-based trace selection - Free energy minimization - Statistical ensemble reasoning ================================================================================ MATHEMATICAL FOUNDATION ================================================================================ CORE PROBABILISTIC MODEL: The CoT framework models reasoning as: p_θ(y, r | x) = p_θ(r | x) · p_θ(y | x, r) Where: - x ∈ X: input problem - y ∈ Y: final answer - r = (r₁, ..., r_T): reasoning trace (sequence of tokens) - θ: model parameters VARIATIONAL LOWER BOUND (ELBO): The evidence lower bound: log p_θ(y | x) ≥ E_{q_φ(r|x,y)}[log p_θ(y | x, r)] - KL(q_φ(r|x,y) || p_θ(r|x)) Where q_φ(r|x,y) is the variational posterior approximating the true posterior. JOINT PROBABILITY: The reasoning trace probability factorizes: p_θ(r | x) = Π_{t=1}^T p_θ(r_t | r_{1:t-1}, x) Log-likelihood: log p_θ(r | x) = Σ_{t=1}^T log p_θ(r_t | r_{1:t-1}, x) INFORMATION-THEORETIC FORMULATION: Mutual information between input and output given reasoning: I(X; Y | R) = H(Y | R) - H(Y | X, R) Entropy of reasoning trace: H(R | X) = -Σ_{r} p_θ(r | x) log p_θ(r | x) Conditional entropy of answer: H(Y | X, R) = -Σ_{y,r} p_θ(y, r | x) log p_θ(y | x, r) QUANTUM SUPERPOSITION: Quantum state representation: |ψ⟩ = Σ_{r} α_r |r⟩ ⊗ |y_r⟩ Where: - |ψ⟩: quantum state representing superposition - α_r = √(p_θ(r | x)): amplitude - |r⟩: basis state for reasoning trace - |y_r⟩: answer state conditioned on r Measurement probability: P(y | x) = |⟨y | ψ⟩|² = |Σ_{r: y_r=y} α_r|² GRAPH-THEORETIC REPRESENTATION: Reasoning as graph G = (V, E): - V = {v₁, ..., v_T}: reasoning steps (vertices) - E = {(v_i, v_j) | v_i → v_j}: causal dependencies (edges) Path probability: P(path) = Π_{(v_i,v_j)∈path} P(v_j | v_i, x) Shortest reasoning path: r* = argmin_{r} [-log p_θ(r | x) + λ·L(r)] Where L(r) is length penalty and λ is regularization. STATISTICAL MECHANICS: Energy function: E(r, x) = -log p_θ(r | x) = -Σ_{t=1}^T log p_θ(r_t | r_{1:t-1}, x) Boltzmann distribution: p_θ(r | x) = (1/Z(x)) exp(-E_θ(r, x) / T) Partition function: Z(x) = Σ_{r} exp(-E_θ(r, x) / T) Free energy: F(x) = -T log Z(x) = -T log Σ_{r} exp(-E_θ(r, x) / T) SELF-CONSISTENCY: Marginalized answer distribution: p(y | x) = Σ_{r} p_θ(r | x) · p_θ(y | x, r) Majority voting: ŷ = argmax_{y} Σ_{i=1}^N 𝟙[y_i = y] Weighted voting: ŷ = argmax_{y} Σ_{i=1}^N w_i · 𝟙[y_i = y] Where w_i = p_θ(r_i | x) or w_i = score(r_i). Confidence via entropy: Confidence = 1 - (H(Y | X) / log |Y|) Where H(Y | X) = -Σ_{y} p(y | x) log p(y | x). DECODING STRATEGIES: Greedy (T → 0): r_t = argmax_{r_t} p_θ(r_t | r_{1:t-1}, x) Sampling (Boltzmann): r_t ~ p_θ(r_t | r_{1:t-1}, x) = softmax(logits / T) Nucleus (top-p): r_t ~ p_θ(r_t | r_{1:t-1}, x) · 𝟙[r_t ∈ P_t] Where P_t = smallest set s.t. Σ_{r'∈P_t} p_θ(r' | r_{1:t-1}, x) ≥ p. Quantum: r_t ~ |ψ_t⟩ where |ψ_t⟩ = M_t |ψ_{t-1}⟩ COMPUTATIONAL COMPLEXITY: Time: O(T · |V| · d) where: - T: max reasoning length - |V|: vocabulary size - d: model dimension Space: O(T · d) for storing reasoning trace.

Proposed by dependabot[bot]Remove VLLM documentation and references Remove all VLLM-related documentation since VLLMWrapper class no longer exists in the codebase. Changes: - Delete vllm.md and vllm_integration.md documentation files - Delete swarms_of_vllm.py example file - Remove VLLM references from README.md, model_providers.md, and other docs - Update llama4.md to use standard model_name approach instead of VLLMWrapper <!-- readthedocs-preview swarms start --> ---- 📚 Documentation preview 📚: https://swarms--1187.org.readthedocs.build/en/1187/ <!-- readthedocs-preview swarms end -->
Proposed by Steve-Dusty**Describe the bug** In your documentation, you mention integration with vLLM, for example: ```python from swarms.utils.vllm_wrapper import VLLMWrapper ``` However, in the latest version (swarms==8.6.0), there is no module named vllm_wrapper under swarms.utils. Could you please clarify if the vLLM integration has been removed or relocated? If it has been deprecated, it would be helpful to update the documentation accordingly. **To Reproduce** Steps to reproduce the issue: 1. Install the latest version of swarms: ```bash pip install swarms==8.6.0 ``` 2. Try importing the vLLM wrapper as shown in the documentation: ```python from swarms.utils.vllm_wrapper import VLLMWrapper ``` 3. You’ll get the following error: ``` ModuleNotFoundError: No module named 'swarms.utils.vllm_wrapper' ``` **Expected behavior** from swarms.utils.vllm_wrapper import VLLMWrapper should work as shown in the docs, or the docs should reflect the current implementation.
Proposed by haowangcoderDescription: This PR adds x402 payment integration to the Agent Orchestration Protocol (AOP), enabling every agent in an AOP server to be monetized using the x402 payment protocol (Coinbase Commerce). This feature builds on the existing middleware system to seamlessly integrate cryptocurrency payments into agent tool executions. The implementation includes: - PaymentConfig dataclass for configuring payment parameters per agent - Automatic payment middleware injection when payment is enabled - Payment verification middleware that follows the same pattern as existing middleware - Structured payment-required responses with payment instructions - Per-agent payment configuration, allowing different agents to have different pricing Key Features: - Per-agent monetization: Each agent can have its own payment configuration - Automatic middleware integration: Payment middleware is automatically injected when enabled - Type-safe configuration: Uses dataclass with validation - Payment instructions: Returns structured payment info when payment is required - Seamless integration: Works with existing middleware system from PR #1183 Issue: https://github.com/kyegomez/swarms/issues/1171 Dependencies: - This PR depends on PR #1183 (AOP Middleware implementation) - No additional dependencies required (uses standard library dataclass) Tag maintainer: kye@swarms.world (swarms.structures) Twitter handle: https://x.com/IlumTheProtogen How It Works in Practice: 1. Configuration: When adding an agent, you can optionally provide a PaymentConfig: ```python from swarms import Agent, AOP from swarms.structs.aop import PaymentConfig payment_config = PaymentConfig( enabled=True, price="$0.01", pay_to_address="0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb", network_id="base-sepolia", description="AI-powered research agent" ) aop = AOP(server_name="MonetizedServer") agent = Agent(agent_name="research-agent", model_name="gpt-4") aop.add_agent(agent, payment_config=payment_config) ``` 2. Execution Flow: When a tool is called: - The system checks if payment_config is enabled for that agent - If enabled, it automatically creates and injects a payment middleware function - Payment middleware runs FIRST in the middleware chain (before custom middlewares) - Payment middleware checks context for payment_proof or payment_header - If no payment proof is found, it raises ValueError with payment instructions - The error handler detects payment_required flag and returns structured response - If payment proof exists, execution continues normally 3. Payment Middleware Behavior: - Checks if payment is enabled (if not, returns immediately) - Looks for payment_proof or payment_header in the context dictionary - If missing, sets payment_required=True and payment_instructions in context - Raises ValueError with payment requirement message - The exception is caught by the middleware error handler - Returns JSON response with payment_required=True and payment_instructions 4. Response Format: When payment is required, the response includes: ```json { "result": "", "success": false, "error": "Payment required: $0.01 per request...", "payment_required": true, "payment_instructions": { "price": "$0.01", "pay_to_address": "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb", "network_id": "base-sepolia", "description": "AI-powered research agent", "facilitator_url": "https://x402.org/facilitator", "input_schema": {...}, "output_schema": {...} } } ``` 5. Integration with Existing Middleware: - Payment middleware uses the same MiddlewareType signature - Follows the same execution pattern as custom middlewares - Automatically injected into middleware chain when payment enabled - Runs before custom middlewares (payment check happens first) - Uses same exception handling mechanism Technical Implementation: 1. PaymentConfig Model: - Python dataclass with __post_init__ validation - Validates price format (must start with $) - Validates wallet address format when payment is enabled - Stores payment configuration (price, address, network, etc.) 2. Payment Middleware Factory: - create_payment_middleware() function creates middleware function - Returns a function matching MiddlewareType signature - Middleware checks payment_config.enabled flag - Verifies payment proof from context - Sets payment_required and payment_instructions in context on failure 3. Automatic Injection: - In _register_tool(), checks config.payment_config.enabled - Creates payment middleware if enabled - Adds it to middleware_chain before custom middlewares - Middleware chain is then executed in order 4. Error Handling: - Payment middleware raises ValueError when payment required - Exception handler checks context["payment_required"] flag - Returns structured response with payment instructions - Preserves existing error handling for other middleware failures Architecture Flow Diagram: ```mermaid graph TD A[Tool Call Received] --> B[Validate Required Parameters] B --> C{Task Provided?} C -->|No| D[Return Error] C -->|Yes| E[Prepare Params & Context] E --> F{Payment Config Enabled?} F -->|Yes| G[Create Payment Middleware] F -->|No| H[Skip Payment Middleware] G --> I[Add Payment Middleware to Chain] H --> J[Add Custom Middlewares to Chain] I --> J J --> K[Execute Middleware Chain] K --> L{Payment Middleware Check} L -->|Payment Required| M{Payment Proof Found?} M -->|No| N[Set payment_required=True] N --> O[Raise ValueError with Instructions] O --> P[Return Payment Required Response] M -->|Yes| Q[Continue to Custom Middlewares] L -->|No Payment Check| Q Q --> R[Execute Custom Middlewares] R --> S{Middleware Exception?} S -->|Yes| T[Return Error Response] S -->|No| U[Extract Modified Params] U --> V{Queue Enabled?} V -->|Yes| W[Execute via Queue] V -->|No| X[Direct Execution] W --> Y[Return Result] X --> Y ``` Usage Example: ```python from swarms import Agent, AOP from swarms.structs.aop import PaymentConfig # Create payment configuration payment_config = PaymentConfig( enabled=True, price="$0.10", pay_to_address="0xYourWalletAddress", network_id="base-sepolia", description="Premium AI research agent" ) # Initialize AOP aop = AOP(server_name="MonetizedAOP") # Add agent with payment research_agent = Agent( agent_name="premium-research", model_name="gpt-4", system_prompt="You are an expert researcher..." ) aop.add_agent( research_agent, payment_config=payment_config ) # Start server aop.run() ``` Benefits: 1. Per-Agent Monetization: Each agent can have independent payment settings 2. Automatic Integration: No manual middleware management required 3. Type Safety: Pydantic validation ensures correct configuration 4. Consistent Pattern: Uses same middleware system as existing features 5. Flexible Pricing: Different agents can have different prices 6. Clear Error Messages: Structured payment instructions for clients Backward Compatibility: This change is fully backward compatible. The payment_config parameter is optional and defaults to None. Existing code without payment configuration will continue to work without modification. Agents without payment_config will behave exactly as before.

Proposed by aparekh02Description: This PR adds custom middleware support to the Agent Orchestration Protocol (AOP) class, enabling users to intercept and modify tool executions before they reach the agent. This feature allows for cross-cutting concerns such as authentication, input validation, logging, rate limiting, and request transformation to be implemented in a modular and reusable way. The middleware system follows a simple, Pythonic design where middleware functions receive the tool execution context and can modify parameters and context in-place. Middlewares are applied in order, and exceptions raised by middleware will stop execution, making it suitable for authentication and authorization use cases. Key Features: - Type-safe middleware definition with MiddlewareType - In-place parameter and context modification - Exception-based request rejection (for auth failures) - Works with both queue-based and direct execution modes - Comprehensive error handling and logging Issue: https://github.com/kyegomez/swarms/issues/1176 Dependencies: None Tag maintainer: @kyegomez Twitter handle: https://x.com/IlumTheProtogen Technical Implementation: 1. Middleware Type Definition The middleware type is defined as a Callable that receives tool execution context: ```python # Middleware type definition # A middleware function receives the tool execution context and can modify inputs/outputs. # Middleware functions are called before tool execution and can modify params and context in-place. # Args: # tool_name: Name of the tool being executed # params: Dictionary of tool parameters (task, img, imgs, correct_answer, max_retries) # Can be modified in-place by the middleware # context: Additional context dictionary (agent, config, etc.) # Can be modified in-place by the middleware # Returns: # None (modifications are done in-place) MiddlewareType = Callable[[str, Dict[str, Any], Dict[str, Any]], None] ``` 2. Constructor Integration The middlewares parameter is added to the AOP __init__ method: ```python def __init__( self, server_name: str = "AOP Cluster", description: str = "A cluster that enables you to deploy multiple agents as tools in an MCP server.", agents: any = None, port: int = 8000, transport: str = "streamable-http", verbose: bool = False, traceback_enabled: bool = True, host: str = "localhost", queue_enabled: bool = True, max_workers_per_agent: int = 1, max_queue_size_per_agent: int = 1000, processing_timeout: int = 30, retry_delay: float = 1.0, persistence: bool = False, max_restart_attempts: int = 10, restart_delay: float = 5.0, network_monitoring: bool = True, max_network_retries: int = 5, network_retry_delay: float = 10.0, network_timeout: float = 30.0, log_level: Literal[ "DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL" ] = "INFO", middlewares: Optional[List[MiddlewareType]] = None, *args, **kwargs, ): ``` The middlewares are stored as an instance variable: ```python self.middlewares: List[MiddlewareType] = middlewares or [] ``` 3. Middleware Execution Flow Middleware is applied in the _register_tool method, before tool execution: ```python # Prepare params and context for middleware params = { "task": task, "img": img, "imgs": imgs, "correct_answer": correct_answer, "max_retries": max_retries, } context = { "agent": agent, "config": config, "tool_name": tool_name, } # Apply middleware in order for middleware in self.middlewares: try: middleware(tool_name, params, context) except Exception as e: # Middleware exceptions should stop execution # This allows middleware to reject requests (e.g., auth failures) error_msg = f"Middleware error for tool '{tool_name}': {str(e)}" logger.warning(error_msg) if config.traceback_enabled: logger.debug( f"Middleware traceback: {traceback.format_exc()}" ) # Return error response instead of continuing return { "result": "", "success": False, "error": error_msg, } # Extract params after middleware processing task = params.get("task", task) img = params.get("img", img) imgs = params.get("imgs", imgs) correct_answer = params.get("correct_answer", correct_answer) max_retries = params.get("max_retries", max_retries) ``` Architecture Flow Diagram: ```mermaid graph TD A[Tool Call Received] --> B[Validate Required Parameters] B --> C{Task Provided?} C -->|No| D[Return Error] C -->|Yes| E[Prepare Params Dict] E --> F[Prepare Context Dict] F --> G[Apply Middleware 1] G --> H[Apply Middleware 2] H --> I[...

Modularity: Cross-cutting concerns are separated from business logic 2. Reusability: Middleware functions can be shared across multiple AOP instances 3. Testability: Middleware functions can be unit tested independently 4. Flexibility: Users can chain multiple middlewares for complex workflows 5. Security: Easy to implement authentication and authorization 6. Observability: Logging and metrics can be added transparently Backward Compatibility: This change is fully backward compatible. The middlewares parameter is optional and defaults to None. Existing code without middleware will continue to work without modification.

Proposed by IlumCIDescription: This PR implements a REACT (Reason, Act, Observe) workflow for the Agent class when max_loops is set to "auto". This brings structured reasoning and action capabilities similar to how modern AI coding assistants like Cursor handle complex, multi-step tasks. Issue: https://github.com/kyegomez/swarms/issues/1178 The REACT workflow enables agents to: 1. Create a detailed step-by-step plan for the given task 2. Execute each subtask through a structured "Think -> Act -> Observe" loop 3. Use specialized tools (action, subtask_complete, objective_complete) to track progress 4. Work through tasks systematically until completion Key Changes: - Added REACT workflow implementation in _run_react_workflow() method - Integrated REACT tools: action, subtask_complete, and objective_complete - When max_loops="auto", the agent now uses the REACT workflow instead of simple infinite loops - Context length is set to infinite (sys.maxsize) during REACT workflows to prevent context limit issues - Users can integrate their own custom tools alongside REACT tools - Maintains backward compatibility - existing functionality remains unchanged How REACT Works: REACT (Reason, Act, Observe) is a reasoning framework that combines: - Reasoning: The agent thinks about what needs to be done - Acting: The agent takes actions using tools - Observing: The agent observes the results and adjusts its approach This creates a feedback loop where the agent can iteratively refine its approach based on the results of previous actions. How Cursor Uses REACT: Cursor uses a REACT-like workflow to handle complex coding tasks: 1. It breaks down user requests into smaller subtasks 2. For each subtask, it reasons about what needs to be done 3. It takes actions (editing files, running commands, etc.) 4. It observes the results and continues to the next subtask 5. It uses tools like "action", "subtask_complete", and "objective_complete" to track progress This allows Cursor to handle multi-file edits, complex refactorings, and multi-step debugging tasks systematically. How Swarms Now Uses REACT: When max_loops="auto" is set, Swarms agents now follow this workflow: ```mermaid graph TD A[User Task] --> B{max_loops = 'auto'?} B -->|Yes| C[REACT Workflow] B -->|No| Z[Standard Loop] C --> D[Create Plan] D --> E[Generate Step-by-Step Plan] E --> F[Store Plan in Memory] F --> G[REACT Loop Start] G --> H[Think: Analyze Current Subtask] H --> I[Act: Use action tool] I --> J[Observe: Review Results] J --> K{Subtask Complete?} K -->|Yes| L[Call subtask_complete tool] K -->|No| H L --> M{All Subtasks Done?} M -->|No| G M -->|Yes| N[Call objective_complete tool] N --> O[Return Full History] O --> P[End] style C fill:#e1f5ff style D fill:#fff4e1 style G fill:#e8f5e9 style N fill:#f3e5f5 ``` 1. Plan Creation Phase: - The agent analyzes the task and creates a detailed, numbered plan - This plan breaks down the objective into clear, actionable subtasks - The plan is stored in memory and displayed to the user 2. Execution Phase: - For each subtask, the agent enters a "Think -> Act -> Observe" loop - The agent uses the "action" tool to execute specific steps - The agent tracks completed subtasks using "subtask_complete" - The agent continues until all subtasks are done 3. Completion Phase: - When all subtasks are complete, the agent calls "objective_complete" - The workflow terminates and returns the full conversation history Key Features: - Infinite context length during REACT workflows to prevent truncation - Custom tool integration alongside REACT tools - Progress tracking through subtask completion - Detailed logging and error handling - Graceful restoration of original context length after workflow completion Technical Implementation: - Added REACT_ACTION_TOOL, REACT_SUBTASK_COMPLETE_TOOL, and REACT_OBJECTIVE_COMPLETE_TOOL - Created _create_react_plan() method to generate initial plans - Created _handle_react_tool_call() method to parse and execute REACT tool calls - Created _run_react_workflow() method to orchestrate the entire REACT process - Modified _run() method to check for max_loops="auto" and route to REACT workflow - Integrated REACT_SYS_PROMPT from swarms.prompts.react_base_prompt Code Examples: 1. Basic REACT Workflow Usage: ```python from swarms import Agent # Initialize agent with max_loops="auto" to enable REACT workflow agent = Agent( model_name="gpt-4o", max_loops="auto", system_prompt="You are a helpful assistant that can break down complex tasks." ) # Run a complex task - agent will automatically create a plan and execute it result = agent.run("Build a web scraper that fetches data from a website and saves it to a CSV file") ``` 2. REACT Workflow with Custom Tools: ```python from swarms import Agent def search_web(query: str) -> str: """Search the web for information about a query.""" # Implementation here return f"Search results for: {query}" def save_to_file(content: str, filename: str) -> str: """Save content to a file.""" # Implementation here return f"Saved to {filename}" # Agent with custom tools - REACT tools are automatically included agent = Agent( model_name="gpt-4o", max_loops="auto", tools=[search_web, save_to_file], system_prompt="You are a research assistant." ) # Agent will use both REACT tools (action, subtask_complete, objective_complete) # and custom tools (search_web, save_to_file) during execution result = agent.run("Research Python best practices and save findings to a file") ``` 3. REACT Tool Definitions: ```python # REACT_ACTION_TOOL - For executing actions within subtasks REACT_ACTION_TOOL = { "type": "function", "function": { "name": "action", "description": "Execute an action or use a tool to make progress on the current subtask.", "parameters": { "type": "object", "properties": { "action_description": {"type": "string"}, "action_result": {"type": "string"} }, "required": ["action_description", "action_result"] } } } # REACT_SUBTASK_COMPLETE_TOOL - For marking subtasks as complete REACT_SUBTASK_COMPLETE_TOOL = { "type": "function", "function": { "name": "subtask_complete", "description": "Mark the current subtask as complete.", "parameters": { "type": "object", "properties": { "subtask_number": {"type": "integer"}, "subtask_summary": {"type": "string"} }, "required": ["subtask_number", "subtask_summary"] } } } # REACT_OBJECTIVE_COMPLETE_TOOL - For marking entire objective as complete REACT_OBJECTIVE_COMPLETE_TOOL = { "type": "function", "function": { "name": "objective_complete", "description": "Mark the entire objective as complete.", "parameters": { "type": "object", "properties": { "final_summary": {"type": "string"} }, "required": ["final_summary"] } } } ``` 4. Workflow Routing in _run() Method: ```python def _run(self, task, img=None, streaming_callback=None, *args, **kwargs): # ... existing code ... # Use REACT workflow when max_loops is "auto" if self.max_loops == "auto": return self._run_react_workflow( task=task, img=img, streaming_callback=streaming_callback, *args, **kwargs, ) # ... continue with standard loop ... ``` 5. Plan Creation Method: ```python def _create_react_plan(self, task: str) -> str: """Create a detailed plan for REACT workflow execution.""" plan_prompt = f"""Create a detailed, step-by-step plan to complete the following task. Break down the task into clear, actionable subtasks that can be completed sequentially. Number each subtask starting from 1. Task: {task} Format your response as a numbered list of subtasks...""" plan = self.llm.run(task=plan_prompt) self.short_memory.add( role=self.agent_name, content=f"Plan created:\n{plan}", ) return plan ``` Dependencies: - No new external dependencies required - Uses existing swarms.prompts.react_base_prompt module - Compatible with existing tool integration system Tag maintainer: @kyegomez Twitter handle: https://x.com/IlumTheProtogen Testing: - Tested with various complex tasks requiring multiple steps - Verified backward compatibility with existing max_loops integer values - Confirmed custom tools work alongside REACT tools - Tested context length handling during long workflows - Verified error handling and recovery mechanisms Backward Compatibility: - All existing functionality remains unchanged - max_loops as integer values work exactly as before - Only max_loops="auto" triggers the new REACT workflow - Existing tools and configurations are fully supported <!-- readthedocs-preview swarms start --> ---- 📚 Documentation preview 📚: https://swarms--1182.org.readthedocs.build/en/1182/ <!-- readthedocs-preview swarms end -->
Proposed by IlumCIDescription: This PR introduces the CR-CA (Causal Reasoning with Counterfactual Analysis) Agent, a revolutionary causal inference system that implements Pearl's Structural Causal Model (SCM) framework. The agent transforms resource management by enabling proactive issue resolution through deep causal analysis, going beyond correlation to understand true cause-and-effect relationships. Issue: https://github.com/kyegomez/swarms/issues/1169 Dependencies: - networkx (for causal graph operations) - numpy (for numerical computations) - pandas (for data handling) - scipy (for optimization and statistical methods) - cvxpy (optional, for convex optimization) Tag maintainer: @kyegomez Twitter handle: https://x.com/IlumTheProtogen ================================================================================ WHAT IS THE CR-CA AGENT? ================================================================================ The CR-CA Agent is a sophisticated causal reasoning system that performs: 1. CAUSAL INFERENCE: Identifies true causal relationships (not just correlations) 2. COUNTERFACTUAL REASONING: Answers "what-if" questions using Pearl's three-step process 3. ROOT CAUSE ANALYSIS: Traces causal chains backward to find ultimate causes 4. OPTIMAL INTERVENTION PLANNING: Finds best interventions using advanced optimization 5. RISK-QUANTIFIED DECISIONS: Provides uncertainty estimates via bootstrap and Bayesian methods Unlike traditional correlation-based approaches, the CR-CA Agent implements structural causal models that enable reliable predictions about intervention effects and counterfactual reasoning. ================================================================================ HOW IT REVOLUTIONIZES RESOURCE MANAGEMENT ================================================================================ PROACTIVE PROBLEM SOLVING: Traditional systems react to problems after they occur. The CR-CA Agent identifies root causes before issues escalate by: - Tracing causal chains backward through the system - Identifying exogenous variables (true root causes) - Ranking intervention opportunities by path strength and depth - Providing actionable intervention recommendations Example: In supply chain management, instead of reacting to backlog spikes, the agent traces back through: backlog → inventory → receipts → supplier_capacity, identifying that supplier capacity constraints are the ultimate root cause. This enables proactive supplier diversification before crises occur. OPTIMIZED RESOURCE ALLOCATION: The agent uses causal understanding to allocate resources efficiently: - Optimizes safety stock levels based on causal relationships, not just historical averages - Balances competing objectives (service level vs. cost) using multi-objective optimization - Quantifies risk using CVaR (Conditional Value-at-Risk) for tail-risk control - Provides confidence intervals for all predictions Example: Instead of setting safety stock to cover 95% of demand variability, the agent optimizes z_alpha (safety factor) based on causal relationships between lead time, demand, and inventory. It calibrates z_alpha to achieve target service levels while minimizing cost, considering the full causal structure. EVIDENCE-BASED DECISIONS: The agent uses causal inference to evaluate intervention effectiveness: - Distinguishes true causal drivers from spurious correlations - Uses do-operator to simulate interventions (active manipulation vs. passive observation) - Performs counterfactual analysis: "What would have happened if we had done X?" - Provides mathematical justification for all recommendations Example: In financial markets, the agent identifies that volume Granger-causes price (rather than just correlating), enabling more reliable trading strategies based on causal understanding rather than patterns that may be spurious. PREDICTIVE INSIGHTS: The agent anticipates cascading effects of interventions: - Models multi-layer chain reactions: "If X affects Y, how does it cascade through Z?" - Detects feedback loops that could amplify or dampen effects - Quantifies cascade probabilities based on path strengths - Provides temporal analysis with distributed lag effects Example: In government policy, a tax rate change affects disposable income, which affects consumption, which affects GDP. The agent models these cascading effects with temporal lags, predicting the full trajectory of policy impacts over time. ================================================================================ MATHEMATICAL FOUNDATION ================================================================================ STRUCTURAL CAUSAL MODELS (SCM): The agent implements Pearl's framework where each variable is defined by a structural equation: y = f(parents(y), ε_y) For linear SCMs: y = Σᵢ βᵢ·xᵢ + ε where βᵢ are structural coefficients representing causal effects, and ε is an error term representing unobserved confounders. STANDARDIZATION: All variables are standardized to z-scores for numerical stability and scale-invariance: z = (x - μ)/σ Prediction in z-space: z_y = Σᵢ βᵢ·z_xi + z_ε After prediction, values are de-standardized: x = z·σ + μ DO-OPERATOR: The do-operator, do(X=x), represents an intervention that sets variable X to value x, breaking its dependence on its parents. This is fundamentally different from conditioning: P(Y | do(X=x)) ≠ P(Y | X=x) The do-operator enables answering interventional questions: "What would happen if we set X to x?" COUNTERFACTUAL REASONING: Pearl's three-step counterfactual reasoning process: 1. Abduction: Infer latent noise terms from factual observations ε = y_factual - Σᵢ βᵢ·x_factual,i 2. Action: Apply do-operator to set intervention values do(X = x*) 3. Prediction: Predict counterfactual outcome using new values but old noise y_cf = Σᵢ βᵢ·x_cf,i + ε This answers: "What would have happened if X had been x* instead of x_factual?" ================================================================================ CORE IMPLEMENTATION DETAILS ================================================================================ EDGE STRENGTH ESTIMATION: The agent estimates causal edge strengths using weighted least squares regression: β = (X' W X + λI)⁻¹ X' W y where: - X is the standardized design matrix of parents - W is diagonal matrix of exponential decay weights: w_i = α^(n-1-i) (newer data weighted more) - λ is ridge regularization parameter - y is the standardized target variable Exponential decay weights: w_i = α^(n-1-i) / Σⱼ α^(n-1-j) This emphasizes recent observations, making the model adaptive to regime changes. PREDICTION PROCESS: 1. Standardize inputs: Convert all variables to z-scores 2. Topological propagation: For each node in topological order: - If intervened: set z_node = z_intervention (do-operator breaks parent dependencies) - Otherwise: compute z_node = Σᵢ βᵢ·z_parent_i 3. De-standardize outputs: Convert z-scores back to raw values ROOT CAUSE ANALYSIS: Path strength computation: Path Strength = ∏(i,j)∈Path β_ij Root causes ranked using multi-objective criteria: f(rc) = w₁·I_exo(rc) + w₂·S_path(rc) - w₃·D(rc) where: - I_exo is indicator for exogenous nodes (true root causes) - S_path is path strength - D is depth (distance from problem) CASCADE ANALYSIS: Cascade probability estimation: P(cascade) = min(0.95, Path Strength · 0.5 + 0.05) For each causal path from intervention variables to outcomes: Path Strength = ∏(i,j)∈Path β_ij OPTIMIZATION METHODS: Gradient-Based Optimization: Objective: maximize predicted outcome max_θ y(θ) Gradient computation using finite differences: ∂y/∂θ_i ≈ (y(θ + ε·e_i) - y(θ))/ε Update rule (gradient descent): θ_{k+1} = θ_k - α·∇_θ y(θ_k) Bellman Optimal Intervention (Dynamic Programming): Value function (Bellman equation): V*(x_t) = max_u_t [r(x_t, u_t) + γ·V*(f(x_t, u_t))] Optimal policy: π*(x_t) = argmax_u_t [r(x_t, u_t) + γ·V*(f(x_t, u_t))] where: - r(x_t, u_t) is immediate reward - γ ∈ [0,1] is discount factor - f(x_t, u_t) is system dynamics (next state) Multi-Objective Optimization (NSGA-II inspired): Weighted sum scalarization: F(x) = Σᵢ wᵢ·fᵢ(x) Pareto dominance: solution x₁ dominates x₂ if: ∀i: fᵢ(x₁) ≥ fᵢ(x₂) ∧ ∃j: fⱼ(x₁) > fⱼ(x₂) RISK QUANTIFICATION: Bootstrap Confidence Intervals: CI_{1-α} = [Q_{α/2}, Q_{1-α/2}] where Q_p is the p-th quantile of bootstrap distribution. Bayesian Inference: Prior: β ~ N(μ₀, σ₀²) Posterior: β | data ~ N(μ_n, σ_n²) Posterior mean: μ_n = (τ₀·μ₀ + τ_likelihood·n·β̂_OLS) / (τ₀ + τ_likelihood·n) where τ = 1/σ² is precision. EXPLAINABILITY: Shapley Value Attribution: φᵢ = Σ_{S ⊆ N\{i}} [|S|!(n-|S|-1)!/n!] · [v(S∪{i}) - v(S)] Properties: - Efficiency: Σᵢ φᵢ = v(N) - v(∅) - Symmetry: Variables with identical contributions have equal Shapley values - Dummy: Variables with no effect have zero Shapley value - Additivity: Shapley values are additive across games Integrated Gradients: IG_i = (x_i - x_i⁰) · ∫₀¹ [∂f/∂x_i](x⁰ + t·(x - x⁰)) dt Approximated using Riemann sum: IG_i ≈ (x_i - x_i⁰) · (1/m) Σⱼ₌₁ᵐ [∂f/∂x_i](x⁰ + (j/m)·(x - x⁰)) ================================================================================ KEY FEATURES IMPLEMENTED ================================================================================ 1.

Proposed by IlumCIDescription: Fix MultiAgentRouter model compatibility issues with structured outputs and JSON parsing Issue: https://github.com/kyegomez/swarms/issues/1137 Dependencies: none Tag maintainer: @kyegomez Twitter handle: https://x.com/IlumTheProtogen Changes made: 1. Added conditional structured outputs - only sets response_format for models that support json_schema (gpt-4.1, gpt-4o, o3-*, o4-*) 2. Added JSON parsing fallback for models without structured outputs - routes to first available agent when JSON parsing fails 3. Updated model names in test file to use correct LiteLLM conventions (anthropic/claude-*, gemini/gemini-*) Why it didn't work last time: The router was unconditionally setting response_format=MultipleHandOffsResponse for all models, causing BadRequestError on models like gpt-3.5-turbo that don't support json_schema structured outputs. Additionally, model names were using incorrect formats (claude-3-5-sonnet instead of anthropic/claude-3-5-sonnet-20241022) causing provider resolution failures. Testing: - gpt-4.1, gpt-4o, o3-mini: Success with structured outputs - gpt-3.5-turbo: Success with JSON parsing fallback - Anthropic/Google models: Fail only due to missing API keys (expected behavior) Results: ``` ===== Model Run Summary ===== gpt-4.1: ✅ Success gpt-4o: ✅ Success gpt-3.5-turbo: ✅ Success gpt-4.1: ✅ Success o3-mini: ✅ Success anthropic/claude-3-5-sonnet-20241022: ❌ Error: litellm.AuthenticationError: AnthropicException - {"type":"error","error":{"type":"authentication_error","message":"x-api-key header is required"},"request_id":"req_011CU5WbPhYDzgh6k3TCBmym"}``` <!-- readthedocs-preview swarms start --> ---- 📚 Documentation preview 📚: https://swarms--1142.org.readthedocs.build/en/1142/ <!-- readthedocs-preview swarms end -->

Proposed by kyegomez## Description Fixed multiple issues in AutoSwarmBuilder that were preventing the execute-swarm-router execution type from working correctly. ## Issue https://github.com/kyegomez/swarms/issues/1115 ## Dependencies No new dependencies required. ## Tag maintainer @kyegomez ## Twitter handle https://x.com/IlumTheProtogen ## Code Changes ### Problem: Missing execute-swarm-router execution type in run method ```python # OLD CODE (broken): def run(self, task: str, *args, **kwargs): try: if self.execution_type == "return-agents": return self.create_agents(task) elif self.execution_type == "return-swarm-router-config": return self.create_router_config(task) elif self.execution_type == "return-agents-objects": agents = self.create_agents(task) return self.create_agents_from_specs(agents) else: raise ValueError(f"Invalid execution type: {self.execution_type}") ``` The execute-swarm-router execution type was missing, preventing _execute_task from being called. ### Solution: Added execute-swarm-router execution type ```python # NEW CODE (working): def run(self, task: str, *args, **kwargs): try: if self.execution_type == "return-agents": return self.create_agents(task) elif self.execution_type == "execute-swarm-router": return self._execute_task(task) elif self.execution_type == "return-swarm-router-config": return self.create_router_config(task) elif self.execution_type == "return-agents-objects": agents = self.create_agents(task) return self.create_agents_from_specs(agents) else: raise ValueError(f"Invalid execution type: {self.execution_type}") ``` ### Problem: Missing JSON parsing in create_agents method ```python # OLD CODE (broken): def create_agents(self, task: str): try: logger.info("Creating agents from specifications") model = self.build_llm_agent(config=Agents) agents_dictionary = model.run(task) return agents_dictionary ``` The LLM returns a JSON string, but the code expected a dictionary. ### Solution: Added JSON parsing ```python # NEW CODE (working): def create_agents(self, task: str): try: logger.info("Creating agents from specifications") model = self.build_llm_agent(config=Agents) agents_dictionary = model.run(task) # Parse JSON string if needed if isinstance(agents_dictionary, str): agents_dictionary = json.loads(agents_dictionary) return agents_dictionary ``` ### Problem: AgentSpec to Agent conversion issue ```python # OLD CODE (broken): for agent_config in agents_list: if isinstance(agent_config, dict): agent_config = AgentSpec(**agent_config) agent = Agent(**agent_config) # TypeError: Agent() argument after ** must be a mapping, not AgentSpec ``` ### Solution: Convert AgentSpec to dictionary ```python # NEW CODE (working): for agent_config in agents_list: if isinstance(agent_config, dict): agent_config = AgentSpec(**agent_config) # Convert AgentSpec to dict for Agent constructor if hasattr(agent_config, 'dict'): agent_dict = agent_config.dict() elif hasattr(agent_config, 'model_dump'): agent_dict = agent_config.model_dump() else: agent_dict = agent_config agent = Agent(**agent_dict) agents.append(agent) ``` The fix ensures AutoSwarmBuilder can successfully create agents and execute swarm workflows with the execute-swarm-router execution type. <!-- readthedocs-preview swarms start --> ---- 📚 Documentation preview 📚: https://swarms--1117.org.readthedocs.build/en/1117/ <!-- readthedocs-preview swarms end -->
