Use when reviewing public HTML forms (no authentication required to reach them) for bot and abuse protection mechanisms.
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
# Protect public forms with CAPTCHA An unprotected registration form can create thousands of spam accounts per minute; an unprotected login form enables credential stuffing attacks that test millions of username/password combinations from data breaches. ## Quick Reference - Public forms (contact, registration, login, password reset, comment) without CAPTCHA are targets for automated abuse - Prefer invisible/automated solutions (Cloudflare Turnstile, Google reCAPTCHA v3, hCaptcha) over interactive challenges that harm UX - Always validate CAPTCHA tokens server-side — client-side validation is bypassable - Rate limiting is complementary to CAPTCHA but not a substitute — bots can solve rate limits with distributed attacks - Honeypot fields (hidden inputs that users never fill but bots do) are a lightweight CAPTCHA alternative for low-risk forms ## Check Identify all public-facing forms (contact, registration, login, password reset, newsletter, comment).

How to install
mdr add thedaviddias/front-end-checklist/form-captcha@sha256:5579694939ce6972The 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.
