Powerball

A marketplace of Claude Code plugins for productivity, software development workflows, and spec-driven development.

• If you are looking for PowerBall Harness, it is located at tim-hub/powerball-harness.
• I also maintained a clone of superpowers for Claude Code only, it give up compatibility to other agents to gain better practices and native features from ClaudeCode.

In theory all the skills and scripts can be worked on other agent coding tools too, however, this was not tested.

Plugins

powerball-personal

Agentic tools for git workflows, issue resolution, code review, creative writing, doc searching, and content translation.

openspec-rewrite

Spec-driven development — setup, explore, propose, implement, verify, sync, and archive changes.

improvement

Skill usage logging and workflow distillation — logs every skill invocation, surfaces a usage summary on session start, and provides skills for capturing and refining reusable workflows.

entrepreneur

Marketing, growth, and PM tools for founders and small teams.

Install

/plugin marketplace add tim-hub/powerball

Install plugins:

• personal (compulsory)
• openspec-rewrite - more
• improvement
• entrepreneur

Then run /get-started to set up statusline and install recommended plugins.

You may need to temporarily disable sandbox mode for the session, because this skill edits ~/.claude to add the statusline script. You can re-enable it after setup.

If you want to set up a skill set of openspec globally, run setup-openspec

Install skills without a plugin

Each plugin's skills can also be installed individually via skills, without adding the marketplace:

bunx skills add https://github.com/tim-hub/powerball/tree/master/personal/skills
bunx skills add https://github.com/tim-hub/powerball/tree/master/improvement/skills
bunx skills add https://github.com/tim-hub/powerball/tree/master/writing/skills

Add --skill <name> to install a single skill from that folder, or -g to install globally.

Manual installation

Clone the repository to your local machine.
