Claude Code Plugin Discovery Now Shows Commands, Agents, and Skills Before You Install
Claude CodeClaude Code v2.1.145 upgrades the /plugin Discover and Browse screens to surface a plugin's full manifest — including its commands, agents, skills, hooks, and MCP/LSP servers — before installation. Previously, developers had to install a plugin to discover what it actually contained. This eliminates the install-to-inspect cycle and makes the plugin marketplace meaningfully more browsable.

Plugin Discovery: See Everything Before You Install
Claude Code v2.1.145 brings a significant quality-of-life upgrade to the plugin ecosystem: the /plugin Discover and Browse screens now display a plugin's complete capability profile before installation. Specifically, you can now see a plugin's commands, agents, skills, hooks, and MCP/LSP servers directly in the discovery UI.
Why This Matters
The Claude Code plugin ecosystem has grown substantially — ClaudePluginHub now indexes hundreds of thousands of components across community plugins. With that scale, discoverability becomes a real friction point. Previously, the only way to know exactly what a plugin contributed to your Claude Code environment was to install it, inspect the result, and potentially uninstall if it wasn't what you needed.
The updated Discover and Browse screens solve this by surfacing the full manifest pre-install. If a plugin declares three custom agents, a set of slash commands, and an MCP server for a specific API, you see all of that upfront — making it possible to make an informed install decision.
Plugin Validation Improvements
v2.1.145 also tightens plugin authoring feedback. The claude plugin validate command now flags skills: entries that point at a file instead of a directory and suggests the correct parent directory path. This catches a common authoring mistake that previously passed validation silently.
Additionally, an infinite loop bug was fixed where a skill using context: fork could repeatedly re-invoke itself instead of running normally. This was a subtle but potentially session-blocking issue for anyone building forked-context skills.
Context
These changes are part of Anthropic's broader effort to mature the Claude Code plugin ecosystem from a power-user feature into a more polished, marketplace-style experience. Alongside the pre-install manifest visibility, recent releases have added plugin marketplace timestamps, plugin-specific LSP server visibility in the details pane, and improved plugin discovery search.
