DevAgentRadar → Claude Code

You are helping me adopt a real coding-assistant change. Work only from the facts below. Do not invent features.

Context

Assistant: Claude Code Proposal: Toggle /diff in fullscreen to watch uncommitted changes as Claude edits Summary: Upgrade to Claude Code v2.1.260, enter fullscreen, and run /diff so uncommitted changes appear beside the conversation as Claude edits. Clear a long transcript with ctrl+l/cmd+k, and only trust /rewind when checkpoint backups actually exist. Primary source: https://github.com/anthropics/claude-code/releases/tag/v2.1.260

Why it matters

v2.1.260 adds a fullscreen diff panel, toggled with /diff, that sits beside the conversation and shows uncommitted changes as Claude edits. Review the working tree in-session instead of waiting for a late git diff. Fullscreen ctrl+l / cmd+k now clears the transcript view like a terminal clear; scroll up for earlier messages so a long edit loop stays readable next to the panel. Fold rewind into the same review loop: /rewind and --rewind-files no longer report success when checkpoint backups were missing and nothing was restored, and they no longer leave stale file-read tracking from rewound-away turns (which caused "File unchanged since last read" stubs and full-file re-injection after external edits). When you run a skill or slash command from the IDE, keep the line selection so the "N lines selected" context reaches Claude.

Suggested actions

1. Upgrade to Claude Code v2.1.260, enter fullscreen, and run /diff so the uncommitted-changes panel opens beside the conversation as Claude edits.
2. Leave /diff toggled on during Edit/Write turns and review each uncommitted hunk in that panel instead of leaving the session to run git diff.
3. In fullscreen press ctrl+l (Windows/Linux) or cmd+k (macOS) to clear the transcript view like a terminal clear; scroll up for earlier messages without closing the diff panel.
4. Before /rewind or --rewind-files, confirm checkpoint backup files exist; v2.1.260 no longer reports success when nothing was restored and no longer keeps stale file-read tracking from rewound-away turns.
5. When launching a skill or slash command from the IDE, keep the current line selection so the "N lines selected" context is sent to Claude.

Your job

1. Restate the change in one sentence.
2. Propose a minimal plan for my repo (or a throwaway pilot).
3. Implement only what I approve; prefer small diffs and tests.
4. Call out risks (permissions, breaking APIs, cost).

Start by confirming you understood the proposal.
