What's Wrong?

What was the problem?

The /plugin marketplace add command has a bug where it constructs the git URL as https://github.com/obra/superpowers-marketplace.git/ (with a trailing slash after .git). GitHub
returns a 500 error for URLs with that trailing slash, even though the repository is perfectly accessible otherwise.

The workaround was to manually clone the repository to the expected location (~/.claude/plugins/marketplaces/obra-superpowers-marketplace), which I've done for you.

You should now be able to use the superpowers marketplace. This is a bug that should be reported to the Claude Code team at https://github.com/anthropics/claude-code/issues.

What Should Happen?

Do not include the trailing slash
