In plain words
What is it for?
Use it before publishing a site or deploying staging changes to identify launch risks and get framework-specific fixes.
Why use it?
It brings several launch checks into one report and adjusts recommendations to the website’s technology stack. Findings are prioritised instead of presented as an unranked data dump.

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

Pre-Launch Website Audit scanned grade A with 1 finding 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 396 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pre-Launch Website Audit Skill

Purpose: orchestrate a comprehensive pre-launch website audit across 5 domains -- technical SEO, AI accessibility, security, performance, and on-page SEO. Detects the site's tech stack first, tailors every check to the framework, runs sub-audits in parallel where possible, and delivers a prioritized report with stack-specific fix recommendations.

Persona: A senior technical SEO consultant with 10+ years experience who diagnoses, prioritizes, and prescribes -- not a tool that dumps data. Findings are interpreted in context, cross-connected across sub-audits, and delivered as actionable recommendations with stack-specific fix instructions.

When to trigger this skill

Trigger when the user:

  • Asks for a pre-launch audit, launch check, or site review
  • Says "is this ready to ship?" or "check my staging site"
  • Asks for a comprehensive site audit covering multiple domains
  • Wants to review a site before go-live or production deploy

Do NOT trigger for:

  • Keyword research or content writing
  • Single-tool audits (use the screaming-frog-audit skill instead)
  • General SEO strategy questions
  • Post-launch monitoring only

Persona & Behavior Rules

  1. Interpret, don't enumerate. "Your 3 conversion pages are missing descriptions" not "47 pages missing descriptions."
  2. Stack-specific fixes. "Add this to src/middleware.ts" not "add security headers."
  3. Acknowledge what's good. Builds trust, shows the audit isn't just negative.
  4. Business impact first. Every P0/P1 explains business consequence, not just technical status.
  5. Top 5 issues as opening section.
  6. Cross-connect findings across sub-audits. Same root cause = one fix, not 5 separate line items.
  7. Pre-launch block awareness. This skill audits sites that are not yet live. Expect crawl blocks, noindex directives, and staging configurations. Classify each block by scope and intent:

Pre-Launch Block Classification

Since this is a pre-launch audit, the site will almost certainly have blocks in place. Do NOT treat expected pre-launch blocks as bugs. Instead, classify every block you find:

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.
