What it does

Frappe Code Review is an agent skill from frappe/skills. Review code for any Frappe application — a checklist distilled from years of engineering practice on correctness, security, performance, concurrency, readability, API design, and testing. Use this when reviewing a diff, a PR, or a piece of code for quality and security, or when you want a reviewer's checklist grounded in hard-won Frappe/ERPNext lessons.

Its SKILL.md is about 3.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code review, API design and Plain language and style rules. The repository describes itself as: Agent skills for Frappe App development.

When your agent uses it

  • Tasks that involve Code review
  • Tasks that involve API design
  • Tasks that involve Plain language and style rules

Example prompts

  • “/frappe-code-review”

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Correctness & stability (highest consequence)
  2. Security
  3. Performance is correctness
  4. Concurrency
  5. Readability & maintainability
  6. API design & backward compatibility
  7. Testing
  8. Error messages, logging & observability

What it can do on your machine

Read from SKILL.md and the folder at commit 0bef982. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Frappe Code Review loads about 3.8k tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 1,998 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
When it runs · the whole SKILL.md, loaded when a task matches
~3.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,998 words (~3,785 tokens).

“A reviewer's checklist for Frappe applications. Protect correctness, security, and the future maintainer, in that order of consequence. The sections below run in that order — spend most attention on §1 and §2. Prefer a root-cause fix over a workaround…”
