Why are Claude Code hooks not working?

[huang041]

I installed the plugin using the following commands:

# Add this repo as a marketplace
/plugin marketplace add affaan-m/everything-claude-code

# Install the plugin
/plugin install everything-claude-code@everything-claude-code

After installation, I asked Claude Code to run npm run dev, but the hook did not trigger as expected.

I checked the documentation and noticed that the hook configuration uses a matcher like:

"matcher": "tool == \"Bash\" && tool_input.command matches \"(npm run dev|pnpm( run)? dev|yarn dev|bun run dev)\""

It seems that this matcher syntax is not supported, which might be why the hook is not working in my case.
