Can I share resources between different plugins?

Due to plugin caching, you should keep all scripts and assets inside the plugin directory. For logic sharing, use skill invocation rather than relative file paths.

How do I test a plugin locally before publishing?

You can add your local directory as a marketplace using '/plugin marketplace add ./path' and then install it with '/plugin install' to test its functionality.

What is required to start a Claude Code plugin?

At minimum, a standalone plugin requires a directory containing a .claude-plugin/plugin.json manifest and a README.md file.

What are event hooks in Claude Code?

Hooks are scripts or commands triggered by specific events like PreToolUse or SessionStart, allowing plugins to intercept or augment Claude's behavior.

How do I manage multiple plugins in one repository?

Use a marketplace.json file with 'strict: false' to consolidate metadata, allowing multiple plugins to coexist without individual manifests.
