Activates a high-intensity task execution mode for Claude Code that enforces persistent progress and exhaustive verification until all objectives are met.
Ultrawork (also known as Sisyphus Mode) is a specialized productivity skill designed for complex, multi-step engineering tasks that require obsessive attention to detail and unwavering momentum. It transforms Claude's behavior from a standard assistant into a proactive agent that minimizes back-and-forth questioning, utilizes maximum search depth for research, and implements a 'todo-continuation-enforcer' to ensure no task is left unfinished. By automating diagnostics and verification after every change, it ensures high-quality output while maintaining an aggressive pace of development, making it ideal for deep refactoring and autonomous feature implementation.
Key Features
01Maximum Search Depth: Automatically applies 'very thorough' parameters to all exploration and documentation searches.
02Continuous Auto-Diagnostics: Runs LSP diagnostics and verification checks immediately after every file modification.
030 GitHub stars
04Todo-Continuation Enforcement: Prevents the agent from stopping until every item on the task list is marked as complete.
05Autonomous Decision Making: Reduces friction by making reasonable engineering decisions instead of pausing for clarification.
06Atomic Task Decomposition: Instantly breaks down complex user requests into granular, actionable todo lists.
Use Cases
01Refactoring large legacy codebases where exhaustive verification and persistent execution are required.
02Deep-dive debugging sessions that involve navigating complex documentation and multi-file dependencies.
03Autonomous feature development where the user defines a goal and needs the agent to work through the entire implementation cycle.
