This directory contains a test extension demonstrating pi-mono's extensibility.

The extension is at .pi/extensions/test-extensibility.ts and loads automatically.

cd ~/code/flow
pi

Once pi is running, try these:

use the counter tool to increment by 5

increment the counter 3 times, then show me the value

run: echo "hello world"

(Watch the console for [test-ext] Tool called: bash)

run: rm -i test.txt

(Should show a warning notification)

Type directly:

/count

The extension logs to console. Look for [test-ext] prefixed messages.

1. Custom Tools - counter tool with multiple actions
2. Event Hooks - tool_call and turn_end listeners
3. Custom Commands - /count slash command
4. Session Events - Reset state on session_start
5. UI Interactions - ctx.ui.notify() for warnings

Edit .pi/extensions/test-extensibility.ts to:

• Add more tools
• Block dangerous operations (return { block: true })
• Add keyboard shortcuts with pi.registerShortcut()
• Register custom LLM providers with pi.registerProvider()
