Use when reviewing form components, API payloads, or client-side storage to identify fields that are collected but not consumed by a stated feature.
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.
What the file says
# Collect only the minimum personal data necessary Collecting more data than necessary increases the blast radius of a breach, exposes your organisation to regulatory fines, and erodes user trust. GDPR Article 5(1)(c) makes data minimisation a legal obligation for any controller processing EU residents' data — but it is also sound engineering practice regardless of jurisdiction. ## Quick Reference - Collect only fields your application actually needs to function - Document the purpose for every piece of personal data you store - Prefer anonymous or pseudonymous data over identifiable data where possible - Clear client-side storage (localStorage, sessionStorage, cookies) on logout or after a defined retention window - Never send raw PII to analytics, monitoring, or client-side logs ## Check Audit the form fields, API request bodies, and client-side storage keys in this codebase to identify any personal data collected beyond what the stated feature requires. Also inspect analytics and logging payloads for raw email addresses, names, phone numbers, or full query strings that leak PII. ## Fix …

How to install
mdr add thedaviddias/front-end-checklist/data-minimisation@sha256:a907c60442166c62The line at the top of this page pins the label git:20261004.4b0ddb9, 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.
