What the file says

# Frappe Jinja Templates Syntax

> Deterministic Jinja reference for Print Formats, Email Templates, Notification Templates, and Portal Pages in Frappe v14/v15/v16.

---

## When to Use This Skill

USE when:
- Creating or modifying Print Formats (Jinja-based)
- Writing Email Templates with dynamic fields
- Building Portal Pages (`www/*.html`) with Python controllers
- Writing Notification Templates (system/email/SMS)
- Registering custom Jinja methods or filters via `hooks.py`

DO NOT USE for:
- Report Print Formats — they use JavaScript templating (`{%= %}`), NOT Jinja
- Client Scripts — see `frappe-syntax-clientscripts`
- Server Scripts — see `frappe-syntax-serverscripts`

---

## Decision Tree: Which Template Type?

```
Need a printable document?
├─ YES → Is it for a Query/Script Report?
│        ├─ YES → Use JS Template ({%= %}), NOT Jinja
│        └─ NO  → Use Jinja Print Format
└─ NO  → Is it for email?
         ├─ YES → Is it triggered by workflow/notification?
         │        ├─ YES → Notification Template (Jinja)
         │        └─ NO  → Email Template (Jinja)
         └─ NO  → Is it a web page?
                  ├─ YES → Portal Page (www/*.html + .py controller)
