Monitor

Create monitors for anything. User defines what to check, skill handles scheduling and alerts.

Data Storage

text

~/monitor/
├── monitors.json       # Monitor definitions
├── config.json         # Alert preferences
└── logs/               # Check results
    └── {name}/YYYY-MM.jsonl

Create on first use: mkdir -p ~/monitor/logs

Scope

This skill:

• ✅ Stores monitor definitions in ~/monitor/
• ✅ Runs checks at specified intervals
• ✅ Alerts user on status changes

Execution model:

• User explicitly defines WHAT to monitor
• User grants any permissions/tools needed
• Skill only handles WHEN and ALERTING

This skill does NOT:

• ❌ Assume access to any service or endpoint
• ❌ Run checks without user-defined instructions
• ❌ Store credentials (user provides via environment or other skills)

Requirements

Required:

• curl — for HTTP checks

Optional (for alerts):

• PUSHOVER_TOKEN / PUSHOVER_USER — for push notifications
• Webhook URL — user provides their own endpoint

Used if available:

• openssl — for SSL certificate checks
• pgrep — for process checks
• df — for disk space checks
• nc — for port checks

Core Rules

1. User Defines Everything

When user requests a monitor:

1. WHAT: User specifies what to check
2. HOW: User provides method or grants tool access
3. WHEN: This skill handles interval
4. ALERT: This skill handles notifications

Example flow:

text

User: "Monitor my API at api.example.com every 5 minutes"
Agent: "I'll check HTTP status. Alert you on failures?"
User: "Yes, and check SSL cert too"
→ Monitor stored with user-defined checks

2. Monitor Definition

In ~/monitor/monitors.json:

json

{
  "api_prod": {
    "description": "User's API health",
    "checks": [
      {"type": "http", "target": "https://api.example.com/health"},
      {"type": "ssl", "target": "api.example.com"}
    ],
    "interval": "5m",
    "alert_on": "change",
    "requires": [],
    "created": "2024-03-15"
  }
}

3. Common Check Types

User can request any of these (or others):

Type	What it checks	Tool used
http	URL status + latency	curl
ssl	Certificate expiry	openssl
process	Process running	pgrep
disk	Free space	df
port	Port open	nc
custom	User-defined command	user specifies

4. Confirmation Format

text

✅ Monitor: [description]
🔍 Checks: [what will be checked]
⏱️ Interval: [how often]
🔔 Alert: [when to notify]
🔧 Requires: [tools/access needed]

5. Alert on Change

• Alert when status changes (ok→fail, fail→ok)
• Include failure count
• Recovery message when back to OK
• Never spam repeated same-status

6. Permissions

The requires field lists what user granted:

• Empty = basic checks only (curl, df, pgrep)
• ["ssh:server1"] = user granted SSH access
• ["docker"] = user granted Docker access

Agent asks before assuming any access.
