Use when working with utility functions in Frappe v14-v16. Covers frappe.utils.* for date/time, number/money, string, validation, and file path operations. Prevents reinventing stdlib alternatives that break timezone awareness, locale formatting, or multi-tenancy. Keywords: frappe.utils, nowdate, flt, cint, fmt_money, getdate,, date calculation, format number, money format, validate email, how to calculate days between. add_days, date_diff, validate_email, pretty_date, get_files_path.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add impertio-studio/frappe_claude_skill_package/frappe-core-utils@sha256:844f7bf46f26101aThe line at the top of this page pins the label v3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
