## 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] LLM --> ThoughtChain[Thought Chain] 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[ToolDefinition] --> Name[Tool Name] Def --> Desc[Description] 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?}

Loop -->|Yes| Next[Generate Next Thought] 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]

subgraph "Input/Output Mapping" MapOutput --> Direct[Direct Value] MapOutput --> Extract[Extract From Previous] MapOutput --> Transform[Transform Values] end

## Workflow Configuration

Workflows are defined in the `workflows.json` file located in the root directory of the project. This file contains predefined sequences of tool calls that can be executed with a single command.

### File Location and Structure

- The `workflows.json` file must be placed in the project root directory (same level as package.json)
- The file follows this structure:

{ "workflows": { "workflowName1": { "description": "Description of what this workflow does", "inputSchema": { "param1": "string", "param2": "string" }, "steps": [ { "id": "step1_id", "toolName": "tool-name", "params": { "param1": "{workflow.input.param1}" } }, { "id": "step2_id", "toolName": "another-tool", "params": { "paramA": "{workflow.input.param2}", "paramB": "{steps.step1_id.output.content[0].text}" } } ], "output": { "summary": "Workflow completed message", "details": ["Output line 1", "Output line 2"] } } } }

### Parameter Templates

Workflow step parameters support template strings that can reference:
- Workflow inputs: `{workflow.input.paramName}`
- Previous step outputs: `{steps.stepId.output.content[0].text}`

### Triggering Workflows

Use the `run-workflow` tool with:

Run the newProjectSetup workflow with input {"productDescription": "A task manager app"}

## Detailed Tool Documentation

Each tool in the `src/tools/` directory includes comprehensive documentation in its own README.md file. These files cover:

*   Tool overview and purpose
*   Input/output specifications
*   Workflow diagrams (Mermaid)
*   Usage examples
*   System prompts used
*   Error handling details

Refer to these individual READMEs for in-depth information:

*   `src/tools/fullstack-starter-kit-generator/README.md`
*   `src/tools/prd-generator/README.md`
*   `src/tools/research/README.md`
*   `src/tools/rules-generator/README.md`
*   `src/tools/task-list-generator/README.md`
*   `src/tools/user-stories-generator/README.md`
*   `src/tools/workflow-runner/README.md`
*   `src/tools/map-codebase/README.md`

## Tool Categories

### Analysis & Information Tools

*   **Code Map Tool (`map-codebase`)**: Scans a codebase to extract semantic information (classes, functions, comments) and generates either a human-readable Markdown map with Mermaid diagrams or a structured JSON representation with absolute file paths for imports and enhanced class property information.
*   **Context Curation Tool (`curate-context`)**: Intelligent codebase analysis and context package curation with 8-phase workflow pipeline, intelligent codemap caching, language-agnostic project detection supporting 35+ programming languages, and multi-strategy file discovery for AI-driven development tasks.
*   **Research Tool (`research`)**: Performs deep research on technical topics using Perplexity Sonar, providing summaries and sources.

### Planning & Documentation Tools

*   **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
