description	Configure Memoh hooks in /data/.memoh/hooks.json, including events, matchers, command/tool actions, decisions, on_error behavior, append_context, and validation. Use when the user asks to inspect, create, update, debug, or explain workspace hooks.

Hooks Setup

Use this skill when the user wants to inspect, create, update, debug, or explain Memoh hooks.

Files

• User hooks live at /data/.memoh/hooks.json.
• Detailed schema, events, payloads, and examples live in references/reference.md.

Read references/reference.md before adding anything beyond an empty config or a simple logging hook.

Empty Config

If /data/.memoh/hooks.json is missing, create:

{
  "version": 1,
  "enabled": true,
  "hooks": []
}

Minimal Workflow

1. Read /data/.memoh/hooks.json.
2. Preserve existing hooks unless the user asks to replace them.
3. Choose the narrowest event and matcher.
4. Prefer logging hooks with on_error: "ignore".
5. Use on_error: "block" only for guardrail hooks that should deny on failure.
6. Validate JSON syntax before finishing.

Common Pattern

{
  "version": 1,
  "enabled": true,
  "defaults": {
    "timeout": "10s",
    "on_error": "fail",
    "max_output_bytes": 65536,
    "trigger_nested_hooks": false
  },
  "env": {},
  "hooks": [
    {
      "name": "log workspace commands",
      "event": "AfterWorkspaceCommand",
      "enabled": true,
      "priority": 10,
      "matcher": 
       
        
           
           
           
        
      
    
  

Action Output

Command and tool actions may return:

{
  "decision": "allow",
  "reason": "optional explanation",
  "append_context": "optional context"
}

Allowed decisions are allow, deny, ask_approval, and append_context.
