frappe-backend

frappe-backend is a skill for Claude Code from Dkm0315/frappe-agent. It costs 53 tokens per session (215 once invoked), scanned A, original, MIT.

Guidance for Frappe server-side development, mainly using Python with some related JavaScript interactions. It covers document events, APIs, scheduled jobs, database changes, reports, and server-side scripts.

In plain words
What is it for?
Use it to implement or review document behavior, hooks, server methods, background jobs, migrations, report backends, API contracts, and permission-aware backend logic.
Why use it?
It helps keep business rules, services, integrations, and permissions separate and avoids accidentally exposing internal code as a public API. It also helps determine whether a configuration or script is enough instead of writing a full feature.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

frappe-backend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Treat Frappe backend work as a Python-first system with important JavaScript touchpoints.

Cover:

  • controllers and document lifecycle methods
  • hooks
  • whitelisted methods
  • scheduler jobs and background work
  • patches and migrations
  • server scripts when they are the right layer
  • report backends
  • client-to-server API contracts

Principles:

  • prefer framework APIs over ad hoc patterns
  • keep imports clean and explicit
  • use permissions deliberately
  • separate document logic, service logic, and integration logic
  • avoid accidental public APIs

Before writing code, decide whether the request should instead be handled by:

  • Custom Field
  • Property Setter
  • Client Script
  • Server Script
  • Workflow
  • Report
  • Workspace

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
