How Cline Processes a User Prompt Internally

Based on the codebase analysis, here's how Cline processes a user prompt internally:

Initial Prompt Reception

• User input is received through VS Code's webview interface
• The WebviewProvider (src/core/webview/index.ts) handles the initial interaction

Context Management (src/core/context-management/ContextManager.ts)

// Gathers context including:
- Current workspace state
- Open files and editor state
- Previous conversation history
- Active .clinerules configuration
- Current task state

Task Processing (src/core/task/index.ts)

The task processor determines what actions to take based on:

• User prompt content
• Current context
• Available tools
• Previous task state

Tool Selection Logic

Cline decides which tools to use based on:

a) Code Operations

• If prompt mentions code modifications → VS Code Workspace API
• If requesting file creation → File System Operations
• If viewing code → File reading operations

b) Terminal Operations

• If requiring command execution → Terminal API
• If running build/test commands → Terminal with appropriate CWD
• If starting servers → Terminal with async handling

c) Browser Operations

• If web server is running → Browser preview tool
• If requiring web content → Web content fetching tools
• If documentation needed → Documentation viewer

d) LLM Interaction

• For understanding user intent
• For generating code or text
• For analyzing results
• For planning next steps

Safety Checks

• Validates file operations against .clineignore
• Requires approval for sensitive operations
• Maintains checkpoints for reversibility
• Validates tool inputs

Response Generation

• Processes tool outputs
• Formats response for user
• Updates UI state
• Maintains conversation context
