Description

Running the following command fails with "Plugin not found in any marketplace":

/plugin install dotnet-aspnet@dotnet-agent-skills --force

Error

Plugin "dotnet-aspnet" not found in any marketplace

  • Claude Code version: (latest)

extent analysis

TL;DR

The issue might be resolved by checking the plugin name, version, or source in the installation command.

Guidance

  • Verify that the dotnet-aspnet plugin exists in the dotnet-agent-skills source and is correctly named.
  • Check if the dotnet-agent-skills source is properly configured and accessible.
  • Ensure that the Claude Code version is compatible with the dotnet-aspnet plugin.
  • Try installing the plugin without specifying the source to see if it's available in the default marketplace.

Example

No code snippet is provided as it's not necessary for this issue.

Notes

The solution assumes that the dotnet-aspnet plugin and dotnet-agent-skills source are correctly set up. If the issue persists, further investigation into the plugin and source configuration may be required.

Recommendation

Apply workaround: Try installing the plugin without specifying the source to see if it's available in the default marketplace, as this can help determine if the issue is with the source or the plugin itself.
