frappe-syntax-serverscripts skillA

frappe-syntax-serverscripts is agent-read markdown (skill) from impertio-studio/frappe_claude_skill_package: Use when writing Python code for ERPNext/Frappe Server Scripts including Document Events, API endpoints, Scheduler Events, and Permission Queries. Prevents the #1 AI mistake: using import statements in Server Scripts (sandbox blocks ALL imports). Covers frappe.* methods, event name mapping, and correct v14/v15/v16 syntax. Keywords: Server Script, frappe, ERPNext, sandbox, import, doc event, validate, on_submit, before_save, server script example, import not allowed, sandbox rules, which script t.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Frappe Server Scripts — Complete Reference

Server Scripts are Python scripts managed via **Setup > Server Script** in the
Frappe/ERPNext UI. They run inside a **RestrictedPython sandbox**.

## CRITICAL: The Sandbox Rule

```
┌──────────────────────────────────────────────────────────────────┐
│  ALL import STATEMENTS ARE BLOCKED                               │
│                                                                  │
│  import json             → ImportError: __import__ not found     │
│  from datetime import *  → ImportError: __import__ not found     │
│  import frappe           → ImportError (even frappe itself!)     │
│                                                                  │
│  EVERYTHING you need is pre-loaded in the frappe namespace.      │
│  NEVER write an import line. ALWAYS use frappe.utils.*, etc.     │
└──────────────────────────────────────────────────────────────────┘
```

**ALWAYS** use the pre-loaded namespace instead of imports:

| Blocked import | Use instead |
|---|---|
| `import json` | `frappe.parse_json()` / `frappe.as_json()` |
| `from datetime import date` | `frappe.utils.today()` / `frappe.utils.now_datetime()` |
