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

shipping-and-launch 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 11d 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.

Shipping and Launch

Overview

Ship with confidence. The goal is not just to deploy — it's to deploy safely, with monitoring in place, a rollback plan ready, and a clear understanding of what success looks like. Every launch should be reversible, observable, and incremental.

When to Use

  • Deploying a feature to production for the first time
  • Releasing a significant change to users
  • Migrating data or infrastructure
  • Opening a beta or early access program
  • Any deployment that carries risk (all of them)

The Pre-Launch Checklist

Code Quality

  • All tests pass (unit, integration, e2e)
  • Build succeeds with no warnings
  • Lint and type checking pass
  • Code reviewed and approved
  • No TODO comments that should be resolved before launch
  • No console.log debugging statements in production code
  • Error handling covers expected failure modes

Security

  • No secrets in code or version control
  • npm audit shows no critical or high vulnerabilities
  • Input validation on all user-facing endpoints
  • Authentication and authorization checks in place
  • Security headers configured (CSP, HSTS, etc.)
  • Rate limiting on authentication endpoints
  • CORS configured to specific origins (not wildcard)

Performance

  • Core Web Vitals within "Good" thresholds
  • No N+1 queries in critical paths
  • Images optimized (compression, responsive sizes, lazy loading)
  • Bundle size within budget
  • Database queries have appropriate indexes
  • Caching configured for static assets and repeated queries

Accessibility

  • Keyboard navigation works for all interactive elements
  • Screen reader can convey page content and structure
  • Color contrast meets WCAG 2.1 AA (4.5:1 for text)
  • Focus management correct for modals and dynamic content
  • Error messages are descriptive and associated with form fields
  • No accessibility warnings in axe-core or Lighthouse

Infrastructure

  • Environment variables set in production
  • Database migrations applied (or ready to apply)
  • DNS and SSL configured
  • CDN configured for static assets
  • Logging and error reporting configured
  • Health check endpoint exists and responds

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.
