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 10d 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.

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:

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.
