What problem does it solve? Writing, debugging, and refactoring code manually is slow and error-prone, especially when changes must be tested safely without risking the host system. This Skill provides a structured development workflow that implements code changes and validates them in an isolated sandbox before delivery. ## Core Features & Use Cases - Code Implementation: Write scripts, APIs, and automation with error handling, comments, and adherence to existing project conventions. - Sandboxed Testing: Execute and validate code with the code_executor tool in an isolated workspace before applying changes. - Debugging & Refactoring: Diagnose failures, design implementations, and refactor code with documentation of all changes. - Use Case: Ask the assistant to write a Python script that parses CSV files; it designs the approach, implements the code, runs it in the sandbox to verify, and documents usage. ## Quick Start Ask the assistant to write and test a Python script that parses a CSV file in a sandboxed workspace.
