Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.02342 |
| Opus 5 | $0.00023 | $0.01171 |
| Sonnet 5 | $0.00009 | $0.00468 |
| Haiku 4.5 | $0.00005 | $0.00234 |
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.
This is a copy
80% identical to shipping-and-launch — 105 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.
How it starts
The opening of the file, as written. The whole thing — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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) — run via
code_execution_tool - 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.logdebugging statements in production code - Error handling covers expected failure modes
Security
- No secrets in code or version control
-
npm auditshows 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
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.

Release Checklist
Check release readiness and record a release note. Use for release and rollback requests.
