Xline is a VS Code plugin built on Cline, designed to enhance coding productivity with customizable AI Agents.
It comes pre-configured with top-performing models like GPT-4.1、Claude-3.7-sonnet、Claude-3.5-sonnet、DeepSeek-chat-V3-0324, allowing you to build projects from scratch using natural language interactions - all for free :)
It dynamically calls tailored tools based on your needs, such as analyzing code files, editing code, or executing commands. Xline also is an "Agent Lab" for solving specific programming challenges, and everyone receives a free usage quota to experiment with its features.
Hack Your Vibe-Coding!
Xline introduces Prompt Tools, bringing a new intelligent partner to your coding experience. This revolutionary feature acts as a professional assistant in your chat sessions, bridging communication between you and AI.
Build-in tools:
api_documenter - Used for creating comprehensive API documentation. It helps ensure all necessary elements are included such as base URLs, HTTP methods, parameter requirements, request/response examples, status codes, error handling, and authentication requirements.
architecture_advisor - Assists with system design and architectural decisions. This tool helps evaluate trade-offs between different architectural approaches when starting new projects, implementing significant features, or addressing concerns about scalability, maintainability, or performance.
code_refactor - Helps refactor complex code by breaking down complex functions into smaller components, eliminating code duplication, applying appropriate design patterns, and improving naming and organization.
code_review - Provides structured code review guidance, offering focused feedback on aspects such as security vulnerabilities, performance optimization, code style adherence to best practices, and test coverage evaluation.
dependency_manager - Helps manage package dependencies, addressing dependency updates, vulnerabilities, version conflicts, and compatibility issues.
error_diagnostics - Used for troubleshooting errors through systematic approach to error diagnosis. Particularly useful when dealing with error messages, stack traces, unexpected behaviors, crashes, or challenges in root cause analysis.
performance_optimizer - Identifies and resolves application performance bottlenecks by providing specific optimization strategies for issues related to rendering, database operations, or algorithm efficiency.
query_optimizer - Helps improve database query performance through strategies for query restructuring, indexing optimizations, and general database performance enhancements.
template_with_followup - A general template tool that can be used in scenarios requiring specific follow-up information. It can be customized to gather additional details needed to complete various tasks effectively.
What can Prompt Tool do
- Define frameworks, coding styles, and frequently used libraries. When the conversation involves information that hasn't been explicitly specified, the model will prompt you for confirmation.
- Shortcut phrases or automatic triggering logic for frequently used prompts, such as triggering a predefined, complex release notes format and definition when sending 'release notes'.
- Any ideas are welcome for discussion on our Discord channel or Github.
Simply put, it has the following key characteristics:
- Simple configuration using natural language
- Configure custom triggers for common coding scenarios
- Inject domain-specific best practices without repetitive instructions
- Enable context-aware interrupts when critical information is missing
When activated, these tools can:
- Interrupt the conversation to guide the AI
- Request missing technical specifications
- Offer decision paths that align with your preferences

[!TIP]
Use the CMD/CTRL + Shift + P shortcut to open the command palette and type "Xline: Open In New Tab" to open the extension as a tab in your editor. This lets you use Xline side-by-side with your file explorer, and see how he changes your workspace more clearly.
Thanks
Special thanks to Cline for their open-source contributions. Without Cline's foundation, I would not have been able to quickly validate my ideas.
