Siga Fixes Claude Code Progress Bars That Keep Filling

A new open-source utility called Siga addresses a frustrating UI bug in Anthropic's Claude Code editor where progress bars continue filling indefinitely after tasks complete. Officially released on October 25, 2026, the tool provides developers with an immediate workaround for visual feedback issues that have disrupted coding workflows in Claude's AI-assisted development environment.

The Progress Bar Problem

Claude Code users have reported a persistent issue where progress indicators fail to stop animating once code generation or analysis tasks finish. The bars continue filling beyond 100%, creating misleading visual feedback that obscures whether operations have actually completed. This behavior affects developer productivity by making it unclear when Claude has finished processing requests, forcing users to look for alternative completion signals or manually verify task status.

The bug appears most frequently during extended code generation sessions and when Claude processes multiple files simultaneously. Developers working on complex refactoring tasks or large codebases have found the issue particularly disruptive, as accurate progress tracking becomes critical for managing multi-step workflows.

How Siga Works

Siga intercepts the progress bar rendering pipeline in Claude Code and implements corrective logic to halt animations when tasks actually complete. The utility monitors completion events from Claude's underlying API and forces progress indicators to reflect true task status. By operating as a lightweight wrapper around the existing interface, Siga maintains compatibility with Claude Code's core functionality while patching the visual feedback loop.

The tool runs as a background process that requires minimal configuration. Developers can install Siga through standard package managers and activate it before launching Claude Code sessions. The utility automatically detects when progress bars reach legitimate completion states and prevents further animation.

Release Date and Availability

Officially released on October 25, 2026, Siga is available as an open-source project on GitHub under the MIT license. The repository includes installation instructions, usage examples, and contribution guidelines for developers interested in extending the tool's capabilities. The initial release targets macOS and Linux environments, with Windows support listed as a planned feature.

Developer souvlakeee maintains the project and has indicated plans for ongoing updates as Claude Code evolves. The repository encourages community feedback on edge cases where the progress bar fix may not perform as expected.

Community Response

Early adopters in AI development communities have welcomed Siga as a practical solution to an annoying UX issue. While some users hope Anthropic will address the underlying bug in future Claude Code updates, the utility provides immediate relief for teams relying on the editor for production workflows. The tool's lightweight architecture and minimal performance overhead have been cited as key advantages.

Discussion threads on developer forums suggest the progress bar issue may stem from asynchronous event handling in Claude Code's frontend, though Anthropic has not publicly confirmed the root cause. Siga's approach of patching the symptom rather than requiring source code changes makes it accessible to developers who cannot wait for an official fix.

What This Means

Siga demonstrates how third-party developers can rapidly address friction points in AI-assisted coding tools through focused utilities. The release highlights both the growing ecosystem around Claude Code and the importance of accurate visual feedback in developer tools. For teams using Claude Code in production environments, Siga offers a low-risk way to improve daily workflow reliability while the underlying issue awaits resolution from Anthropic.
