How do I test a plugin without publishing to npm?

Use the provided dev.sh script to load local files directly into Claude Code via the --plugin-dir flag, allowing for instant feedback without external deployment.

Can I test hooks without starting a full Claude session?

Yes, you can use the test-hook.mjs utility to simulate specific events like SessionStart or PostToolUse in isolation from the command line.

What is the fastest way to reload a modified hook?

For most script and skill changes, simply typing the /clear command in Claude Code will reload the plugin context and apply your updates in about 2 seconds.

How do I monitor plugin logs and performance?

You can use the /prismer:debug-log command within Claude Code or tail the .dev-cache/prismer-debug.log file to see real-time execution data and health summaries.
