How to build a launch checklist with Claude Code

Why does a reusable launch checklist keep missing things?

Because it can only contain what is true of every launch. Analytics instrumented, support documentation updated, rollback plan agreed, stakeholders told: those items are on every template because they always apply, and they are not what goes wrong. What goes wrong is the environment variable that exists in staging and not in production, the migration that runs after the code that depends on it, and the external service whose free tier ends at ten thousand calls a day on a feature you expect to make forty thousand.

Those items are specific to this change, so no template can carry them. They can only come from reading what actually changed, which is the job worth handing to an agent that can read the repository.

What does the diff tell you that the spec does not?

The truth about scope. A specification describes intent, and intent drifts during a build in ways nobody writes down. The diff is the record of what was really done, and six categories of change in it each generate a checklist item automatically.

New configuration values mean something has to be set in an environment you are not looking at. A database migration means deploy ordering and a rollback question. A new external dependency means a key, a quota and a decision about what happens when that service is down. A new feature flag means a default state and a named person who can flip it. Changed public copy means translation and screenshots. A removed or renamed field means something downstream is about to break quietly.

So the request is narrow and specific: compare this branch against the main branch, and list every change that requires an action outside this repository, grouped by whether it happens before deploy, at deploy, or after. That one question produces more useful checklist items than any template, because it is answering about your change rather than about launches in general.

What does the spec tell you that the diff cannot?

The promise, and everyone who needs to hear about it. Code cannot tell you who this feature was built for, what you claimed it would do in the pricing page copy, which customers asked for it and are waiting, or what number you expect to move in the first two weeks. It also cannot tell you what would make you turn it off.

Feed the spec in alongside the diff and ask a different question of it: who needs to know before this appears, what did we promise, and what evidence in the first fourteen days would tell us this was worth building. The output is shorter than the diff-derived list and it contains the items that actually get forgotten, because they live in someone's head rather than in a file.

How do you turn two lists into one checklist people use?

Give every item four fields and reject anything that cannot fill them.

• Action and owner, with a name rather than a team, because a team does not tick a box.
• Timing, as before deploy, at deploy, or after deploy, since ordering is half of what a checklist is for.
• Verification, meaning the specific thing you will look at to know it is done.

The verification field is the one that does the filtering. "Make sure analytics is working" has no verification and survives on every checklist forever. "Confirm the plan_upgraded event appears in the dashboard within 5 minutes of a test upgrade" has one, and it either passes or it does not. Items without a verification step are wishes, and cutting them makes the list short enough that somebody reads it.

Keep the finished checklist as a file in the repository next to the spec rather than in a separate tool. The next launch then starts from a real example of the last one, and an agent can read both. If your team works out of a shared workspace instead, Notion for product managers covers that side of the same habit.

The question most checklists never ask

Which of these changes cannot be undone by reverting the commit. Reverting is the mental model everyone carries into a launch, and it is wrong for a specific and predictable set of changes. A migration that drops a column does not come back when the code does. An announcement email that has already been delivered cannot be recalled. A price change that has created billing records leaves those records behind. Data written in a new shape by the new code stays in the new shape after the rollback.

Ask that question explicitly, because an agent reading a diff will answer it well and nobody thinks to ask it while things are calm. Every yes needs a written plan before deploy: a backfill script, a correction email already drafted, or a decision that this part of the change is a one-way door and gets extra scrutiny now rather than later.

What does support need that engineering never writes down?

Three things, and a diff produces two of them. The first is the list of questions this change will generate: a renamed setting, a moved button and a new permission each create a predictable support ticket, and the changed copy in the diff tells you exactly which words users will search for and fail to find. The second is how to identify an affected account, which matters the moment a flag rolls the change out to a fraction of customers and support cannot tell who has which version.

The third comes from you. What is the workaround while a known gap exists, and what should support say about when it closes. Nothing in the repository answers that, and support will invent an answer if you do not supply one.

Ask for the first two as part of the same diff pass: list every user-visible string that changed, and every condition that decides who sees the new behaviour. That output goes straight into a support note, and it takes about a minute. A launch where support hears about the change from a customer is the version of this that costs a week of goodwill for no reason.

Does this release deserve a launch at all?

Usually not, and treating every release as a launch is how a team trains its own audience to ignore it. A public launch costs positioning work, assets, outreach and a moment of everyone's attention, and it should be spent on changes that alter what the product is for. Everything else deserves release notes and a note to support.

Product Marketing with AI teaches that call directly, across 5 modules covering market insight, narrative and positioning, product exploration, launch planning, and the learning loop afterwards, in 1 week with 2 live sessions. From Idea to Launch with AI comes at it from the earlier end: 1 week, 2 live sessions and 8 microlessons on validating the problem, scoping a tight first version, and choosing distribution moves that get first users without an existing audience. For the vocabulary, the go-to-market strategy entry covers the terms these conversations assume.

Claude Code for Product Managers is the one that teaches the mechanics used above: structuring context so an agent can reason across a repository and your written product documents, and validating what it produces before you act on it, in 1 week with 2 live sessions and 8 microlessons.

Run it backwards on your last launch

Take the launch that went least smoothly this year, pull the branch that shipped it, and generate the checklist now, after the fact. Then compare it to what actually went wrong. The interesting result is not whether the list contains the incident, because it usually does. It is how far up the list the item sits, and whether anybody would have read that far on the day. A checklist that surfaces the right item on line nineteen is a checklist nobody finishes, and shortening it is a separate problem from generating it. The one-pager template is a reasonable place to keep the surviving five items where people will actually see them.
