servicenow（servicenow 开发）

Jace's ServiceNow CLI

Explore and manage ServiceNow instances. Works standalone or with AI agents.

Discovery

Commands are self-documenting. Use these to learn what's available:

jsn commands --md         # Full catalog with descriptions, actions, and hints
jsn <command> --help      # Detailed usage, flags, and examples for any command

Agent Rules

1. Output modes — --json when parsing data; --md when presenting to humans; --agent for automation
2. Use sys_id for updates — All update/delete operations require sys_id
3. Check auth first — Run jsn auth status before operations
4. NEVER logout — Only run jsn auth logout if the user explicitly asks
5. Use --profile <name> to target a specific instance, or jsn config switch <name> to change default

Command Hierarchy

Pick the most specific tool for the job:

1. Specific commands — rules, flows, jobs, etc. — curated views with domain-aware formatting
2. records --table <name> — generic CRUD on any table (the workhorse)
3. rest — raw escape hatch for any REST endpoint
4. Ask the human — if none of the above work. Never generate scripts as a fallback.

JSON Envelope

All commands support --json. The envelope structure:

{
  "ok": true,
  "data": [ ... ],
  "summary": "5 records",
  "breadcrumbs": [
    {"action": "show", "cmd": "jsn records --table incident <sys_id>", "description": "View details"}
  ]
}

Breadcrumbs suggest next commands — follow them for navigation.
