Proof SDK: Editor, collab server, provenance model, and agent HTTP bridge

Summary

Proof SDK is an open-source collaborative document infrastructure that provides an editor, a real-time collaboration server, a provenance model, and an agent-facing HTTP bridge interface. It targets developers who need to connect human collaborative editing and intelligent agent operations within the same document workflow.

Problem

The problem it solves is how to unify multi-user real-time document collaboration, edit history/provenance tracking, and AI/agent-programmable operations within a single document system.
This matters because in human-AI collaborative writing, code/document co-creation, and multi-agent workflows, the system must support not only editing but also auditable changes, comments, suggestions, and state synchronization.
Traditional editors or collaboration backends usually lack a unified agent interface and provenance model, making it difficult to safely connect automation capabilities to collaborative documents.

Approach

The core approach is straightforward: split the collaborative document system into four composable parts—editor, real-time collaboration server, provenance model, and agent HTTP bridge.
The editing layer supports collaborative Markdown editing and includes higher-level operations such as comments, suggestions, and rewrite, not just low-level text editing.
The server exposes document state, snapshots, edit operations, presence, and event streams through a set of public HTTP routes, such as /state, /snapshot, /edit, /ops, and /events/pending.
The agent-facing bridge separately exposes interfaces for state, marks, comments, suggestions, rewrite, and presence, allowing external agents to read documents and submit structured modifications over standard HTTP.
The project also provides an example app and modular packages (such as doc-editor, doc-server, agent-bridge, and doc-store-sqlite) to make further integration easier.

Results

The text does not provide quantitative results such as benchmarks, accuracy, throughput, latency, or user studies.
The strongest concrete claim is that the SDK publicly exposes a complete interface surface: at least 13 canonical routes, covering document creation, state retrieval, snapshots, editing, ops, presence, events, and agent bridge capabilities.
Functionally, it claims support for 4 core capability categories: collaborative Markdown editing, provenance tracking, a real-time collaboration server, and an agent HTTP bridge.
The agent-side interface covers at least 6 interaction categories: state, marks, comments, suggestions, rewrite, and presence, which can support external automation or agent participation in document collaboration.
From an engineering delivery perspective, the repository includes an example app (apps/proof-example) and multiple foundational packages, requires Node.js 18+, and can launch the full system locally with the editor on :3000 and the API/server on :4000.
