frappe-agent-validator: Research & Knowledge for AI Agents | OpenAgentSkill

Overview

Use when reviewing or validating Frappe/ERPNext code against best practices and common pitfalls. Checks generated code before deployment, validates against all 61 frappe-* skills, catches v16 patterns (extend_doctype_class, type annotations), validates ops patterns (bench commands, deployment), and generates correction reports. Keywords: review code, check script, validate deployment, find bugs, code quality, check my code, is this correct, code review, before deploying, best practices check.

Critical Checks by Code Type

Server Script Checks

Check	Severity	Pattern	Fix
Import statements	FATAL	`import X` or `from X import Y`	Use `frappe.utils.X()` directly
Wrong doc variable	FATAL	`self.field` or `document.field`	Use `doc.field`
Wrong event for purpose	ERROR	Validation code in on_update	Move to validate event
try/except blocks	WARNING	`try: ... except:`	Use `frappe.throw()` for validation
No null checks	WARNING	`doc.field.lower()`	Add `if doc.field:` guard

Client Script Checks

Check	Severity	Pattern	Fix
Server-side API calls	FATAL	`frappe.db.get_value()`	Use `frappe.call()`
Missing async handling	FATAL	`let x = frappe.call()`	Use callback or async/await
No refresh after set_value	ERROR	`frm.set_value()` alone	Add `frm.refresh_field()`
Using cur_frm	WARNING	`cur_frm.doc.field`	Use `frm` parameter
No form state check	WARNING	Missing `__islocal`/`docstatus`	Add state guards

Controller Checks

Check	Severity	Pattern	Fix
self.* in on_update	FATAL	`self.field = X` in on_update	Use `self.db_set()`
Circular save	FATAL	`self.save()` in lifecycle hook	Remove self.save()
Missing super()	ERROR	Override without super()	Add `super().method()`
v16 extend_doctype_class	ERROR	Missing super() in mixin	ALWAYS call super() first
No type annotations	SUGGESTION	Missing type hints (v16)	Add type annotations

hooks.py Checks

Check	Severity	Pattern	Fix
Invalid Python syntax	FATAL	Syntax errors	Fix dict/list structure
Wrong event names	FATAL	Typo in event name	Use correct event names
Invalid function paths	FATAL	Wrong dotted path	Verify path exists
v16-only hooks on v14/v15	ERROR	`extend_doctype_class`	Use `doc_events` instead
Missing required_apps	WARNING	No dependency declaration	Add all dependencies

Ops/Bench Checks

Check	Severity	Pattern	Fix
No migrate after hooks	FATAL	hooks.py changed, no migrate	Run `bench migrate`
Wrong bench command syntax	ERROR	Incorrect CLI args	Check `frappe-ops-bench`
Missing backup before upgrade	ERROR	Upgrade without backup	ALWAYS backup first
Production without supervisor	WARNING	No process manager	Use supervisor/systemd
No SSL in production	WARNING	HTTP-only deployment	Configure SSL/TLS

DocType JSON Checks

Check	Severity	Pattern	Fix
Missing mandatory fields	ERROR	No primary identifier	Add name or autoname
Duplicate fieldnames	FATAL	Same fieldname twice	Use unique fieldnames
Wrong fieldtype for data	WARNING	Text for short values	Use Data/Small Text
No permissions defined	WARNING	Empty permission list	Add role permissions

v16 Specific Validations

extend_doctype_class Pattern

# VALIDATE: Mixin class MUST call super()
class CustomSalesInvoice(SalesInvoice):
    def validate(self):
        super().validate()       # REQUIRED - never skip
        self.custom_validation()

    def on_submit(self):
        super().on_submit()      # REQUIRED - never skip
        self.custom_on_submit()

Type Annotations (v16 best practice)

# v16 recommended pattern
def get_customer_balance(customer: str) -> float:
    ...

# Validate: type hints on public API methods
@frappe.whitelist()
def process_order(order_name: str, action: str = "approve") -> dict:
    ...

Data Masking (v16)

# Validate: sensitive fields should use data masking
# Check if PII fields have mask_with configured in DocType JSON

Universal Validation Rules

Security Checks (ALL code types)

No batch commit	HIGH	Commit per record in bulk ops

Error Handling Checks (ALL code types)

Check	Severity	Description
Silent failures	HIGH	`except: pass` without logging

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
