This week: Radar brief — 2026-09-09

What shipped

Claude Codev2.1.260Sep 3, 2026

Added a diff panel that opens beside the conversation in fullscreen mode and shows your uncommitted changes as Claude edits; toggle it with `/diff`

  • Added a likely cause for prompt-cache misses (e.g. tool definitions or system prompt changed, idle past the TTL) to `/cost` and the status line's `prompt_cache` field
  • Added `/reload-plugins` to headless sessions, so it appears in the Claude Code Desktop and SDK command lists
  • +72 more on the Claude Code page

One next step. Copy a prompt into the agent you already use, then approve, defer, or ignore. Nothing auto-applies.

Move Agent Plugins into ~/.agents/plugins and Hub-enable them in Settings → Customize

Cline Desktop v0.0.23 discovers Agent Plugins only from ~/.agents/plugins via the shared Hub. Workspace .agents/plugins is ignored. Put packages with plugin.json there so skills and MCP servers start automatically, then enable each plugin under Settings → Customize.
  1. mkdir -p ~/.agents/plugins && if [ -d .agents/plugins ]; then echo 'Workspace .agents/plugins is ignored in desktop-v0.0.23 — copy each package into ~/.agents/plugins/<name> with its plugin.json'; ls -la .agents/plugins; fi
  2. For every directory in ~/.agents/plugins, open plugin.json and keep only packages whose declared Agent Skills and MCP servers (stdio, Streamable HTTP, or SSE) you want the Hub to validate and start automatically.
  3. In Cline Desktop open Settings → Customize, use the Agent Plugins list (not Cline Plugins), read each plugin's description, badge, and contributed tools, then Hub-enable only the plugins this machine should run.
