What it does
Https is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing whether a website or web application serves content exclusively over HTTPS with a valid certificate.
Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Auditing whether a website
- Web application serves content exclusively over HTTPS with a valid certificate
Example prompts
- “/https”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
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
Https loads about 513 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 251 words of instructions outside code blocks.
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.

Serve all pages over HTTPS
Plain HTTP exposes every request and response to anyone on the network path — ISPs, Wi-Fi operators, and MITM attackers can read passwords, session tokens, and personal data without any warning to the user.
Quick Reference
- All HTTP traffic must redirect to HTTPS with a 301 (permanent) redirect
- TLS certificates must be valid, not expired, and cover all hostnames (including
www) - HTTPS is a prerequisite for HSTS, HTTP/2, Service Workers, geolocation, and other modern APIs
- Use a free certificate from Let's Encrypt or your hosting provider's managed TLS
- Verify the certificate chain with SSL Labs (ssllabs.com/ssltest) — aim for A or A+
Check
Check whether all pages of this website are served over HTTPS. Verify the TLS certificate is valid, not expired, and covers all hostnames. Confirm HTTP requests redirect to HTTPS with a 301 status code.
Fix
Configure the web server to obtain a TLS certificate (e.g., via Let's Encrypt/Certbot), redirect all HTTP requests to HTTPS with a 301 redirect, and ensure all internal links and resources use HTTPS URLs.
Explain
Explain why serving pages over HTTPS is essential for security, what happens when plain HTTP is used, and how to obtain and configure a TLS certificate.
Code Review
Review server config, headers, forms, and integration points related to Serve all pages over HTTPS. Flag exact responses, cookies, or browser behaviors that violate the rule, and verify them against the effective production-like response.
