What problem does it solve?

Real-time collaboration on Mermaid diagrams inside a terminal-first workspace, coordinating human attention and AI-assisted edits through MCP-driven workflows.

Core Features & Use Cases

  • AST-first collaboration model for diagram reasoning and live updates.
  • Shared attention controls (attention.*), follow_ai mode, and selection workflows to coordinate edits.
  • Diagram lifecycle management via diagram and walkthrough tools, xref mapping, and route queries.

Quick Start

Start a collaborative Nereid session by running nereid in a session folder and joining the live diagram workspace.

FAQPage Schema
How do I collaborate on Mermaid diagrams with AI in a terminal workspace?

You can collaborate on Mermaid diagrams by running a session that coordinates human attention and AI-assisted edits through MCP-driven workflows. It applies an AST-first reasoning model to sequence diagrams, flowcharts, and walkthroughs in a live TUI environment.

Can I use MCP to manage live diagram edits and walkthroughs?

Yes, MCP channels the collaboration state using attention, follow_ai, and selection tools to coordinate edits. Diagram lifecycle management, xref mapping, and route queries are driven directly through these MCP sessions.

How does AST-first reasoning work for Mermaid diagram collaboration?

AST-first reasoning enforces deterministic diagram and walkthrough workflows by parsing the Mermaid syntax tree before applying changes. This structured approach ensures safe mutation patterns and reliable session file updates during live collaboration.

What is the best way to coordinate human and AI attention during live flowchart updates?

The best way is using shared attention controls like the attention.* tools and follow_ai mode. These coordinate user and agent focus, ensuring edits, evidence gathering, and selection workflows are synchronized across the live TUI session.

Does this approach support sequence diagrams, route queries, and xref mapping?

Yes, it fully supports sequence diagrams and flowcharts, alongside route queries and xref mapping. These features are managed through dedicated diagram and walkthrough tools within the collaborative session environment.

Why should I use a terminal-first workspace for Mermaid diagram collaboration?

A terminal-first workspace enables real-time, MCP-driven collaboration where users and agents coordinate attention and edits directly. It relies on session files and safe mutation patterns to drive deterministic workflows without leaving the TUI.
