Shipping and Launch skill for Claude Code: pre-launch checks, staged rollout, rollback

Makes your agent run a pre-launch checklist and plan a staged rollout, monitoring and rollback before you deploy.

shipping-and-launch makes the agent work through a checklist before a production launch and plan how to roll it out safely. It loads when you prepare to deploy, ask what needs to be in place before shipping, or need monitoring, a staged rollout or a rollback strategy.

The checklist covers code quality, security, performance, accessibility, infrastructure and documentation. The skill adds feature flag rules, rollout thresholds for advance, hold or roll back, a post-launch check for the first hour and an error budget gate. It bundles no scripts.

Good for

Developers about to deploy to production
Teams opening a beta or migrating data or infrastructure
Anyone who needs a rollback plan before shipping

What it includes

Code quality, security, performance, accessibility, infrastructure and docs
37 checkbox items in six groups.
Pre-launch checklist
Ship behind flags; every flag has an owner and an expiry
Clean up flags within 2 weeks of full rollout; do not nest flags; test both states in CI.
Feature flag strategy
A rollout sequence with advance, hold and roll back thresholds
A table compares error rate, P95 latency, client JS errors and business metrics with baseline.
Staged rollout
Roll back at more than 2x baseline error rate or 50% worse P95 latency
Also on user-reported spikes, data integrity issues or a security vulnerability.
When to roll back
What to monitor, error reporting and a first-hour check
Verify health checks, error rate, latency, critical flows and logs.
Monitoring and observability
Use the SLO error budget as an objective ship or hold gate
A high burn rate during a canary counts as a hold signal.
Error budget release gate
Write the rollback plan before the deploy
A markdown template for the plan.
Rollback strategy
Points to definition-of-done, security, performance and accessibility checklists
These live in the repo-level references folder.

Permissions

Low risk

It plans production launches, so a rushed change to a flag, migration or deploy could affect real users. Review each of those yourself before the agent acts.

Watch out for

Its checklist reaches into deploys and feature flags
It covers environment variables, migrations, flags and rollbacks. Review any deploy, migration or flag change before the agent makes it.
It names audit commands
The security items mention npm audit, pip-audit and cargo audit run in your project.

Questions

What does shipping-and-launch do?

It makes Claude check a change against a pre-launch checklist and plan the launch: feature flags, staged rollout with clear thresholds, monitoring, a first-hour check and a rollback plan.

How do I install shipping-and-launch?

Use the install box above. The README also lists npx skills add addyosmani/agent-skills --skill shipping-and-launch for one skill, and a Claude Code plugin for the whole pack (/plugin marketplace add addyosmani/agent-skills, then /plugin install agent-skills@addy-agent-skills). A one-skill install copies only skills/shipping-and-launch/ and not the repo-level references folder; the README says the skill still works. The skill points to checklists under ../../references/, which a one-skill install does not copy.

Does it deploy for me?

The SKILL.md describes checklists, thresholds and plans. It does not define a deploy command. Your deploy tools still do the shipping.

What are the rollback thresholds?

Roll back when error rate is more than 2x baseline, P95 latency is more than 50% above baseline, new client JS errors affect more than 0.1% of sessions or business metrics fall more than 5%.

Is it safe to run?

It is a text file of instructions and bundles no scripts. Its checklist names commands such as npm audit and touches deploy and flag decisions, so review those changes before the agent makes them.

Does it work in Codex, Cursor or other tools?

The README documents Codex (codex plugin marketplace add addyosmani/agent-skills, then codex plugin add agent-skills@agent-skills, Codex CLI v0.122 or newer), Cursor (copy skills into .cursor/skills/), Gemini CLI, Windsurf, OpenCode, GitHub Copilot, Kiro and others. It says the skills are plain Markdown that work with any agent that accepts instruction files. It does not mention the Claude app.
