Failed plugin installs now show more of the actual error, with a hint on how to see the rest
When a plugin fails to install, Claude Code used to just print the plugin's name and a reason, cut off to 2 items. Now it tells apart internal errors from external ones, shows more of a long or multi-line external error (trimmed to a fixed length with "..." if needed), and adds a hint: pressing Enter on a plugin's details in /plugin shows its full error.
This makes it easier to actually diagnose why a plugin install failed, instead of getting a truncated, uninformative summary, and points you to where you can read the complete error message.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
`/plugin` opens an interactive panel in the terminal CLI. If Claude replies that `/plugin` isn't available in this environment, install another way:security-guidance see the edit

Anthropic's documentation has since written up /plugin, on Explore the .claude directory.
Fixed a crash ("Type error") when opening /mcp or /plugin manage with a malformed claudeAiMcpEverConnected value in ~/.claude.json
