dsh-approval-diff

Every time the model asks to change a file, the native DSH approval card dumps raw tool arguments as plain text with no context and no line numbers. You end up reconstructing the diff in your head on every single ask. dsh-approval-diff replaces that mental gymnastics with a real, readable diff rendered inside the approval card: red and green lines side by side, word-level highlights inside changed lines, and genuine disk-anchored line numbers in the surrounding context. Toggle between split and unified views, just like on GitHub.

Every hunk is anchored to the file on disk at request time, so line numbers are never fabricated. If the file has moved on and the old text no longer matches, the card says so outright instead of presenting a diff that cannot apply. Multiple pending edits to the same file merge into one review: the card shows how many edits are bundled, one decision settles the group, and later same-file asks inherit the outcome you already saw. Deletion commands display the command text so you can read exactly what is about to run before pressing Allow. One-click arming lets you auto-allow edits to that file for the session, with a visible armed state and one-click disarm.

Built for developers who rely on DSH agents to edit, write, or clean up files and want the approval moment to be an actual code review rather than a decode-the-raw-text ritual. It removes the need to become a human diff engine and removes the temptation to auto-approve and hope.
