act101

act101 is a groundbreaking development tool that empowers AI agents to perform language-aware code refactoring and porting across an extensive range of 163 programming languages. This innovative platform allows developers to leverage advanced artificial intelligence capabilities to improve their codebase without the limitations of traditional tools. act101 features a sophisticated Model Context Protocol (MCP) server that exposes a comprehensive suite of operations, including 183 AST-aware refactor operations and 8 porting operations, all designed to enhance productivity and streamline workflows. With built-in codebase analyzers, developers can assess their projects for coupling, dead code, and hotspots, among other factors. The tool is particularly valuable for software engineers, architects, and teams looking to modernize legacy systems or convert codebases between languages with precision and accuracy. act101 stands out by providing a native Rust binary that ensures high performance while maintaining security and privacy, as user code remains on their machines.

Language-Aware Refactoring

act101 enables AI agents to execute a variety of refactoring tasks across 163 programming languages. With operations such as extract-function and rename, developers can enhance code quality while ensuring cross-file consistency. This feature is equipped with automatic checkpointing to facilitate instant undo capabilities, allowing for quick corrections if needed.

Cross-Language Porting

The porting capabilities of act101 facilitate seamless migration of code between different programming languages, such as porting C code to Rust or Ruby to Elixir. This feature utilizes a contract/inventory/ordering/manifest state machine to manage the migration process step by step, ensuring that all dependencies and symbols are correctly accounted for and migrated.

Comprehensive Codebase Analysis

With 30 built-in codebase analyzers, act101 provides developers with critical insights into their project's structure. It assesses factors such as coupling, cycles, and dead code, which helps identify areas of improvement before any modifications are made. This proactive approach ensures a healthier codebase and aids in strategic decision-making.

Pre-Built Agent Skills

act101 includes 10 pre-built agent skills that streamline common engineering workflows, such as architecture audits and code reviews. These skills can be invoked easily within the development environment, enabling teams to utilize best practices in refactoring and migration while saving time on repetitive tasks.
