Bug

Updating the plugin via /plugin menu fails with:

Failed to update: Plugin "Notion" not found

Inspecting plugin info also shows:

Error: Plugin Notion not found in marketplace

Root Cause

There is a name mismatch between the two manifest files:

• .claude-plugin/plugin.json declares "name": "Notion"
• .claude-plugin/marketplace.json declares the plugin as "name": "notion-workspace-plugin"

The /plugin update/info command resolves by the marketplace-level name (notion-workspace-plugin), but the UI displays the name from plugin.json (Notion). When the user triggers an update, it looks up "Notion" in the marketplace index and can't find a match.

Additionally, the old plugin name persists in ~/.claude/settings.json under enabledPlugins, causing a load error on every /reload-plugins even after reinstalling:

Plugin notion-workspace-plugin not found in marketplace notion-plugin-marketplace

Reproduction

1. Install the plugin via /plugin menu
2. Try to update it via /plugin → Update
3. Observe: Failed to update: Plugin "Notion" not found
4. Even after reinstalling, /reload-plugins shows 1 error because settings.json still references the old name

Fix

Align the names so marketplace.json plugin entry "name" matches plugin.json "name" ("Notion").
