Flowglass English (dsh-flowglass-en)

An English-only live session flow visualizer for DeepSeek Harness. Flowglass turns users, assistant responses, tool calls, parallel work, and subagents into an interactive execution graph.

This package has its own npm and runtime identities, so it can be installed without colliding with the original Chinese package.

Features

• Live three-lane visualization for user messages, assistant work, tool calls, and results.
• Clickable details for messages, tools, models, token usage, and subagents.
• Nested subagent navigation and session-aware branch continuation.
• Flow Zoom views for concurrent sessions, including compact, detailed, and map layouts.
• Persistent topology history for evolving 1-to-N branches.
• Configurable refresh interval, default branch count, default view, and tool presentation rules.
• Native right-sidebar integration, Better Sidebar compatibility, and a built-in fallback panel.
• English-only interface, settings, errors, logs, and package metadata. No translation engine is included.
