xby-jsondiff

Comparing two JSON payloads inside an AI conversation typically means copying content out, opening an external diff tool, and pasting results back-a fragmented loop that breaks your train of thought. xby-jsondiff is a DeepSeek Harness client plugin that brings structured JSON diffing directly into the chat, so you never have to leave the current session.

Built on the MCP (Model Context Protocol) and purpose-tuned for AI dialogue workflows, it exposes a single jsonDiff action that performs smart field-level comparison and returns a clean, well-structured diff with fast turnaround. The API key is set once in a chat message and persisted automatically across restarts, eliminating the need to re-enter credentials every time.

If you regularly compare API responses, environment configs, or data snapshots in JSON form, or you want the model to spot structural differences while iterating on prompts, this plugin shortens the debugging loop dramatically. It removes the jump-out-of-conversation step entirely, keeping your attention on the logic that actually matters.
