+# Cline CLI
+
+A command-line interface for Cline, powered by Deno.
+
+## Installation
+
+1. Make sure you have [Deno](https://deno.land/) installed
+2. Install the CLI globally:
+   ```bash
+   cd cli
+   deno task install
+   ```
+
+If you get a PATH warning during installation, add Deno's bin directory to your PATH:
+```bash
+echo 'export PATH="$HOME/.deno/bin:$PATH"' >> ~/.bashrc  # or ~/.zshrc
+source ~/.bashrc  # or ~/.zshrc
+```
+
+## Usage
+
+```bash
+cline <task> [options]
+```
+
+### Security Model
+
+The CLI implements several security measures:
+
+1. File Operations:
+   - Read/write access limited to working directory (--allow-read=., --allow-write=.)
+   - Prevents access to files outside the project
+
+2. Command Execution:
+   - Strict allowlist of safe commands:
+     * npm (install, run, test, build)
+     * git (status, add, commit, push, pull, clone, checkout, branch)
+     * deno (run, test, fmt, lint, check, compile, bundle)
+     * ls (-l, -a, -la, -lh)
+     * cat, echo
+   - Interactive prompts for non-allowlisted commands:
+     * y - Run once
+     * n - Cancel execution
+     * always - Remember for session
+   - Clear warnings and command details shown
+   - Session-based memory for approved commands
+
+3. Required Permissions:
+   - --allow-read=. - Read files in working directory
+   - --allow-write=. - Write files in working directory
+   - --allow-run - Execute allowlisted commands
+   - --allow-net - Make API calls
+   - --allow-env - Access environment variables
+
+### Options
+
+- `-m, --model <model>` - LLM model to use (default: "anthropic/claude-3.5-sonnet")
+- `-k, --key <key>` - OpenRouter API key (required, or set OPENROUTER_API_KEY env var)
+- `-h, --help` - Display help for command
+
+### Examples
+
+Analyze code:
+```bash
+export OPENROUTER_API_KEY=sk-or-v1-...
+cline "Analyze this codebase"
+```
+
+Create files:
+```bash
+cline "Create a React component"
+```
+
+Run allowed command:
+```bash
+cline "Run npm install"
+```
+
+Run non-allowlisted command (will prompt for decision):
+```bash
+cline "Run yarn install"
+# Responds with:
+# Warning: Command not in allowlist
+# Command: yarn install
+# Do you want to run this command? (y/n/always)
+```
+
+## Development
+
+The CLI is built with Deno. Available tasks:
+
+```bash
+# Run in development mode
+deno task dev "your task here"
+
+# Install globally
+deno task install
+
+# Type check the code
+deno task check
+```
+
+### Security Features
+
+- File operations restricted to working directory
+- Command execution controlled by allowlist
+- Interactive prompts for unknown commands
+- Session-based command approval
+- Clear warnings and command details
+- Permission validation at runtime

+TOOL USE
+
+You have access to tools that are executed upon approval. Use one tool per message and wait for the result before proceeding. Each tool must be used with proper XML-style formatting:
+
+<tool_name>
+<parameter1_name>value1</parameter1_name>
+<parameter2_name>value2</parameter2_name>
+</tool_name>
+
+# Available Tools
+
+## execute_command
+Description: Execute a CLI command on the system. Commands run in the current working directory: ${cwd}
+Parameters:
+- command: (required) The command to execute. Must be valid for the current OS.
+Usage:
+<execute_command>
+<command>command to run</command>
+</execute_command>
+
+## read_file
+Description: Read contents of a file. Supports text files and automatically extracts content from PDFs/DOCXs.
+Parameters:
+- path: (required) Path to file (relative to ${cwd})
+Usage:
+<read_file>
+<path>path to file</path>
+</read_file>
+
+## write_to_file
+Description: Write content to a file. Creates directories as needed. Will overwrite existing files.
+Parameters:
+- path: (required) Path to write to (relative to ${cwd})
+- content: (required) Complete file content. Must include ALL parts, even unchanged sections.
+Usage:
+<write_to_file>
+<path>path to file</path>
+<content>complete file content</content>
+</write_to_file>
+
+## search_files
+Description: Search files using regex patterns. Shows matches with surrounding context.
+Parameters:
+- path: (required) Directory to search (relative to ${cwd})
+- regex: (required) Rust regex pattern to search for
+- file_pattern: (optional) Glob pattern to filter files (e.g. "*.ts")
+Usage:
+<search_files>
+<path>directory to search</path>
+<regex>pattern to search</regex>
+<file_pattern>optional file pattern</file_pattern>
+</search_files>
+
+## list_code_definition_names
+Description: List code definitions (classes, functions, etc.) in source files.
+Parameters:
+- path: (required) Directory to analyze (relative to ${cwd})
+Usage:
+<list_code_definition_names>
+<path>directory to analyze</path>
+</list_code_definition_names>
+
+## attempt_completion
+Description: Signal task completion and present results.
+Parameters:
+- result: (required) Description of completed work
+- command: (optional) Command to demonstrate result
+Usage:
+<attempt_completion>
+<result>description of completed work</result>
+<command>optional demo command</command>
+</attempt_completion>
+
+# Guidelines
+
+1. Use one tool at a time and wait for results
+2. Provide complete file content when using write_to_file
+3. Be direct and technical in responses
+4. Present final results using attempt_completion
+5. Do not make assumptions about command success
+6. Do not make up commands that don't exist
+
+# Rules
+
+- Current working directory is: ${cwd}
+- Cannot cd to different directories
+- Must wait for confirmation after each tool use
+- Must provide complete file content when writing files
+- Be direct and technical, not conversational
+- Do not end messages with questions${rulesContent}`;
