collapse-diffs

README

A Claude Code mod that hides the diff under successful Edit and Write tool rows. The row itself (Update(src/auth.ts), Write(src/new.ts)) stays as it is.

Still shown as normal:

a call that errored, with its error text
a change held for review instead of written
any result the mod doesn't recognise

Works in the terminal and in Claude Code for VS Code.

Install

/plugin install collapse-diffs --marketplace Zimoholdijk/collapse-diffs

Answer y to add the marketplace, then pick a scope.

Note

This mod uses Claude Code's early-access plugin API, which can change between releases. If diffs start showing again after an update, the API has likely moved.

Develop

claude plugin validate .
claude plugin test .
