Agent Refactor

The agent refactor feature allows developers to make sophisticated changes to their code across 163 languages, including Python, Rust, TypeScript, and Go. This capability enables actions such as extracting functions, renaming symbols, and moving modules with cross-file consistency. Each operation is AST-aware and comes with automatic checkpointing and instant undo, providing both safety and efficiency.

Agent Port

Act101 includes powerful porting operations that facilitate the migration of code between languages, such as converting C libraries to Rust or Ruby to Elixir. Utilizing port contracts and a port manifest state machine, this feature ensures a structured and organized approach to language migrations, tracking progress step by step and maintaining the integrity of the codebase.

Agent Analyze

With 30 codebase analyzers at your disposal, act101 empowers developers to assess various aspects of their code, including coupling, cycles, and dead code. This feature provides valuable insights into the structural health of a codebase, allowing developers to make informed decisions before initiating changes and improving overall code quality.

Agent Skills

Act101 comes equipped with 10 pre-built agent skills that streamline common engineering workflows. Skills such as architecture audit, code review, and migration assessment can be invoked easily, enhancing productivity and enabling teams to focus on high-value tasks. This feature integrates seamlessly with AI coding agents, making it a versatile tool for modern software development.

Code Refactoring

Developers can leverage act101 to refactor large codebases efficiently. For instance, when updating a legacy Python application, the agent can automatically extract functions, rename variables, and improve code organization, significantly reducing the time spent on manual edits.

Language Migration

When migrating a project from one language to another, such as C to Rust, act101 simplifies the process. The agent utilizes its porting features to ensure that all necessary symbols are accurately translated and dependencies are resolved, minimizing the risk of errors during migration.

Codebase Analysis

Software teams can use act101 to conduct comprehensive codebase analyses. By identifying hotspots, dead code, and structural issues, teams can prioritize refactoring efforts and address technical debt, leading to a cleaner and more maintainable code environment.

Architectural Reviews

Act101 can assist in architectural audits by analyzing code structure and cohesiveness. Developers can utilize the agent’s skills to assess the overall health of a software project, ensuring that it aligns with best practices and is optimized for future scalability.
