Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-design-guidelines scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

88% identical to web-design-guidelines — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Web Interface Guidelines

Review files for compliance with Web Interface Guidelines.

How It Works

  1. Fetch the latest guidelines from the source URL below
  2. Read the specified files (or prompt user for files/pattern)
  3. Check against all rules in the fetched guidelines
  4. Output findings in the terse file:line format

Guidelines Source

Fetch fresh guidelines before each review:

https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md

Use WebFetch to retrieve the latest rules. The fetched content contains all the rules and output format instructions.

Usage

When a user provides a file or pattern argument:

  1. Fetch guidelines from the source URL above
  2. Read the specified files
  3. Apply all rules from the fetched guidelines
  4. Output findings using the format specified in the guidelines

If no files specified, ask the user which files to review.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
