addyosmani/agent-skills is a collection of reusable workflows, quality checks, commands, and other instructions that guide AI coding agents through software development. It is for developers who want agents to follow consistent engineering practices, and the catalogue entries are its packaged skills, commands, agents, plugins, instructions, and hooks.
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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.02641 |
| Opus 5.5 | $0.00023 | $0.01056 |
| Sonnet 5.5 | $0.00011 | $0.00528 |
| Haiku 4.5 | $0.00006 | $0.00264 |
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 17d 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.logdebugging statements in production code - Error handling covers expected failure modes
Security
- No secrets in code or version control
- The ecosystem's dependency audit (
npm audit,pip-audit,cargo 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
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.

shipping-and-launch is a skill published in the GitHub repository addyosmani/agent-skills (111,152 stars, last pushed 14d ago), licensed MIT. It adds 57 tokens to every session and 2,641 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
