Plugin Hook Output Capture Bug Reproduction

Minimal reproduction case for https://github.com/anthropics/claude-code/issues/10412

Issue

Plugin hooks execute successfully but Claude Code never captures/parses their JSON output, while identical inline hooks work correctly.

Setup

This repo contains two nearly-identical bash Stop hooks:

1. Inline hook (configured in .claude/settings.json): plugins/test-plugin/hooks/entrypoints/stop.sh
2. Plugin hook (auto-discovered from plugin): plugins/test-plugin/hooks/entrypoints/stop.sh

Reproduction Steps

Test 1: Plugin hook only

1. Edit .claude/settings.json and comment out the inline hook configuration:

   {
     "hooks": {
       "Stop": []
     },
     "enabledPlugins": {
       "test-plugin": true
     }
   }
   

2. Run Claude Code in this directory

3. Trigger a Stop hook (let Claude finish a response)

4. Check response

Expected: Should see loop of Claude stopping and reevaluating due to exit code 2 from hook

Actual: Claude continues without reevaluation.

Test 2: Inline hook only

1. Edit .claude/settings.json to enable inline hook and disable plugin:

   {
     "hooks": {
       "Stop": [
            {
                "hooks": [
                    {
                        "type": "command",
                        "command": "plugins/test-plugin/hooks/entrypoints/stop.sh"
                    }
                ]
            }
       ]
     },
     "enabledPlugins": {
       "test-plugin": false
     }
   }
   

2. Run Claude Code in this directory

3. Trigger a Stop hook

Works as expected an exit code 2 triggers a reevaluation.
