Semantic Routing System

Vibe Coder uses a sophisticated routing approach to select the right tool for each request:

flowchart TD
    Start[Client Request] --> Process[Process Request]
    Process --> Hybrid[Hybrid Matcher]

    subgraph "Primary: Semantic Routing"
        Hybrid --> Semantic[Semantic Matcher]
        Semantic --> Embeddings[Query Embeddings]
        Embeddings --> Tools[Tool Embeddings]
        Tools --> Compare[Compare via Cosine Similarity]
        Compare --> Score[Score & Rank Tools]
        Score --> Confidence{High Confidence?}
    end

    Confidence -->|Yes| Registry[Tool Registry]

    subgraph "Fallback: Sequential Thinking"
        Confidence -->|No| Sequential[Sequential Thinking]
        Sequential --> LLM[LLM Analysis]

        ThoughtChain --> Extraction[Extract Tool Name]
        Extraction --> Registry
    end

    Registry --> Executor[Execute Tool]
    Executor --> Response[Return Response]

Tool Registry Pattern

The Tool Registry is a central component for managing tool definitions and execution:

flowchart TD
    subgraph "Tool Registration (at import)"
        Import[Import Tool] --> Register[Call registerTool]
        Register --> Store[Store in Registry Map]
    end

    subgraph "Tool Definition"

        Def --> Schema[Zod Schema]
        Def --> Exec[Executor Function]
    end

    subgraph "Server Initialization"
        Init[server.ts] --> Import
        Init --> GetAll[getAllTools]
        GetAll --> Loop[Loop Through Tools]
        Loop --> McpReg[Register with MCP Server]
    end

    subgraph "Tool Execution"
        McpReg --> ExecTool[executeTool Function]
        ExecTool --> GetTool[Get Tool from Registry]
        GetTool --> Validate[Validate Input]
        Validate -->|Valid| ExecFunc[Run Executor Function]
        Validate -->|Invalid| ValidErr[Return Validation Error]
        ExecFunc -->|Success| SuccessResp[Return Success Response]
        ExecFunc -->|Error| HandleErr[Catch & Format Error]
        HandleErr --> ErrResp[Return Error Response]
    end

Sequential Thinking Process

The Sequential Thinking mechanism provides LLM-based fallback routing:

flowchart TD
    Start[Start] --> Estimate[Estimate Number of Steps]
    Estimate --> Init[Initialize with System Prompt]
    Init --> First[Generate First Thought]
    First --> Context[Add to Context]
    Context --> Loop{Needs More Thoughts?}

    Next -->|Standard| AddStd[Add to Context]
    Next -->|Revision| Rev[Mark as Revision]
    Next -->|New Branch| Branch[Mark as Branch]
    Rev --> AddRev[Add to Context]
    Branch --> AddBranch[Add to Context]
    AddStd --> Loop
    AddRev --> Loop
    AddBranch --> Loop

    Loop -->|No| Extract[Extract Final Solution]
    Extract --> End[End With Tool Selection]

    subgraph "Error Handling"
        Next -->|Error| Retry[Retry with Simplified Request]
        Retry -->|Success| AddRetry[Add to Context]
        Retry -->|Failure| FallbackEx[Extract Partial Solution]
        AddRetry --> Loop
        FallbackEx --> End
    end

Session State Management

flowchart TD
    Start[Client Request] --> SessionID[Extract Session ID]
    SessionID --> Store{State Exists?}

    Store -->|Yes| Retrieve[Retrieve Previous State]
    Store -->|No| Create[Create New State]

    Retrieve --> Context[Add Context to Tool]
    Create --> NoContext[Execute Without Context]

    Context --> Execute[Execute Tool]
    NoContext --> Execute

    Execute --> SaveState[Update Session State]
    SaveState --> Response[Return Response to Client]

    subgraph "Session State Structure"
        State[SessionState] --> PrevCall[Previous Tool Call]
        State --> PrevResp[Previous Response]
        State --> Timestamp[Timestamp]
    end

Workflow Execution Engine

The Workflow system enables multi-step sequences:

flowchart TD
    Start[Client Request] --> Parse[Parse Workflow Request]
    Parse --> FindFlow[Find Workflow in workflows.json]
    FindFlow --> Steps[Extract Steps]

    Steps --> Loop[Process Each Step]
    Loop --> PrepInput[Prepare Step Input]
    PrepInput --> ExecuteTool[Execute Tool via Registry]
    ExecuteTool --> SaveOutput[Save Step Output]
    SaveOutput --> NextStep{More Steps?}

    NextStep -->|Yes| MapOutput[Map Output to Next Input]
    MapOutput --> Loop

    NextStep -->|No| FinalOutput[Prepare Final Output]
    FinalOutput --> End[Return Workflow Result]

  • Rules Generator (rules-generator): Creates project-specific development rules and guidelines.
  • PRD Generator (prd-generator): Generates comprehensive product requirements documents.
  • User Stories Generator (user-stories-generator): Creates detailed user stories with acceptance criteria.
  • Task List Generator (task-list-generator): Builds structured development task lists with dependencies.

Project Scaffolding Tool

  • Fullstack Starter Kit Generator (fullstack-starter-kit-generator): Creates customized project starter kits with specified frontend/backend technologies, including basic setup scripts and configuration.

Workflow & Orchestration

  • Workflow Runner (run-workflow): Executes predefined sequences of tool calls for common development tasks.

Generated File Storage

By default, outputs from the generator tools are stored for historical reference in the VibeCoderOutput/ directory within the project. This location can be overridden by setting the VIBE_CODER_OUTPUT_DIR environment variable in your .env file or AI assistant configuration.

Security Boundaries for Read and Write Operations

For security reasons, the Vibe Coder MCP tools maintain separate security boundaries for read and write operations with a security-by-default approach:

  • Read Operations:

    • Code Map Tool: Only reads from directories explicitly authorized through the CODE_MAP_ALLOWED_DIR environment variable
    • Vibe Task Manager: Only reads from directories authorized through the VIBE_TASK_MANAGER_READ_DIR environment variable (defaults to process.cwd())
    • Security Mode: The Vibe Task Manager defaults to 'strict' security mode, which prevents access to system directories like /private/var/spool/postfix/, /System/, and other unauthorized paths
    • Filesystem Security: Comprehensive blacklist enforcement and permission checking prevent EACCES errors and unauthorized file access

  • Write Operations: All output files are written to the VIBE_CODER_OUTPUT_DIR directory (or its subdirectories). This separation ensures that tools can only write to designated output locations, protecting your source code from accidental modifications.

  • Security Implementation: The filesystem security system includes:

    • Adaptive Timeout Management: Prevents operations from hanging indefinitely with intelligent retry and cancellation
    • Path Validation: Comprehensive validation of all file paths before access
    • Permission Checking: Proactive permission verification to prevent access errors
    • System Directory Protection: Built-in blacklist of system directories that should never be accessed

Vibe Task Manager - AI-Native Task Management

The Vibe Task Manager is a comprehensive task management system designed specifically for AI agents and development workflows. It provides intelligent project decomposition, natural language command processing, and seamless integration with other Vibe Coder tools.

Status: Functional and production-ready with 99.9% test success rate, but actively being enhanced with new features and improvements.

Key Features

  • Natural Language Processing: Understands commands like "Create a project for building a React app" or "Show me all pending tasks"
  • Recursive Decomposition Design (RDD): Automatically breaks down complex projects into atomic, executable tasks
  • Artifact Parsing Integration: Seamlessly imports PRD files from VibeCoderOutput/prd-generator/ and task lists from VibeCoderOutput/generated_task_lists/
  • Session Persistence: Enhanced session tracking with orchestration workflow triggers for reliable multi-step operations
  • Comprehensive CLI: Full command-line interface with natural language processing and structured commands
  • Agent Orchestration: Coordinates multiple AI agents for parallel task execution
  • Integration Ready: Works seamlessly with Code Map Tool, Research Tool, and other tools
  • File Storage: All project data stored in VibeCoderOutput/vibe-task-manager/ following established conventions

Quick Start Examples

# Project Management
"Create a new project for building a todo app with React and Node.js"
"List all my projects"
"Show me the status of my web app project"

# Task Management
"Create a high priority task for implementing user authentication"
"List all pending tasks for the todo-app project"
"Run the database setup task"

# Project Analysis (Enhanced with Intelligent Lookup)
"Decompose my React project into development tasks"
"Decompose PID-TODO-APP-REACT-001 into tasks"  # Using project ID
"Decompose \"Todo App with React\" into tasks"  # Using exact name
"Decompose todo into tasks"  # Using partial name (fuzzy matching)
"Refine the authentication task to include OAuth support"
"What's the current progress on my mobile app?"

🎯 Enhanced Project Lookup Features

  • Intelligent Parsing: Automatically detects project IDs, names, or partial matches
  • Comprehensive Validation: Validates project readiness before decomposition
  • Enhanced Error Messages: Provides actionable guidance with available projects and usage examples
  • Multiple Input Formats: Supports project IDs, quoted names, partial names, and fuzzy matching
  • Confidence Scoring: Shows parsing confidence levels for better user feedback

Command Structure

The Vibe Task Manager supports both structured commands and natural language:

Structured Commands:

  • vibe-task-manager create project "Name" "Description" --options
  • vibe-task-manager list projects --status pending
  • vibe-task-manager run task task-id --force
  • vibe-task-manager status project-id --detailed

Natural Language (Recommended):

  • "Create a project for [description]"
  • "Show me all [status] projects"
  • "Run the [task name] task"
  • "What's the status of [project]?"
  • "Parse PRD files for [project name]" (NEW)
