Cursor or Claude Code plus Supabase plus None launch checklist

Confirm the production URL

Preview and production can return different routes, headers, and environment values.

Fix prompt

Plain http requests do not redirect to https. Find the hosting or server layer that owns redirects, add a permanent http to https redirect for all paths, and show me the diff plus a curl -I of the http address.

Run the primary journey from a clean session

A working first screen does not prove the main task completes.

Fix prompt

Cursor prompt: Run the main user journey from a clean browser. Record each request, state change, failure path, and final result. Apply it across the project, run the relevant checks, and show the diff.

Enforce authorization on the server

Hidden buttons do not stop a direct request to a protected action.

Fix prompt

Cursor prompt: List every protected read and write. Enforce identity and ownership on the server for each one, then test a second account against them. Apply it across the project, run the relevant checks, and show the diff.

Validate every server input

Browser validation can be skipped by direct requests.

Fix prompt

Cursor prompt: Add strict server-side validation and length limits to every public or authenticated mutation. Return clear errors without internal details. Apply it across the project, run the relevant checks, and show the diff.

Keep private keys out of browser code

Anyone who opens the page can read this key and use it directly against the service it belongs to, with your account paying for it.

Fix prompt

A {pattern} is bundled into {bundle}. Rotate it, move its use to a server function with server-only env, remove it from client env, rebuild, and verify the prefix is gone from dist. Do not print the value.

Test the main failure path

Timeouts and rejected requests need a truthful, recoverable interface.

Fix prompt

Cursor prompt: Force the main external request to time out and fail. Show a truthful error, preserve user input, and provide a retry that cannot duplicate work. Apply it across the project, run the relevant checks, and show the diff.

Rollback and recovery

Whether you can put the previous version back, and how long that takes.

A URL cannot verify this. A Launch Review can.

Fix prompt

Deploy a trivial change, then roll it back, and time how long the app is wrong for.

Error monitoring

Whether a failure in production reaches a human rather than sitting in a log nobody opens.

A URL cannot verify this. A Launch Review can.

Fix prompt

Trigger a deliberate error in production and see whether anything alerts you within five minutes.

Rate limiting and abuse controls

Whether a script can hammer your forms, sign up loop, or paid endpoints without being slowed down.

A URL cannot verify this. A Launch Review can.

Fix prompt

Send the same form fifty times in a minute from one address and see whether anything stops you.

Apply row-level policies to every table

Whether the row rules behind the app actually stop one signed in account reading another's rows.

A URL cannot verify this. A Launch Review can.

Fix prompt

Sign in as one account and request another account's record by id through the API.

Keep the service role on the server

A service role bypasses row-level access checks and must never reach browser code.

Fix prompt

Cursor prompt: Search browser imports, environment variables, logs, and built files for the service role. Move every privileged operation behind an authenticated server function. Apply it across the project, run the relevant checks, and show the diff.

Sign in and account flows

Whether sign in, password or code reset, and session expiry behave under real use.

A URL cannot verify this. A Launch Review can.

Fix prompt

Sign in as two different accounts in two browsers and try to open the other account's pages by address.

Test personal-data deletion

Whether stored personal details are limited, deletable on request, and out of your logs.

A URL cannot verify this. A Launch Review can.

Fix prompt

Search your logs for an email address you know is in the database and see whether it appears.

Keep personal data out of logs

Email addresses and other personal details can spread into long-lived logging systems.

Fix prompt

Cursor prompt: Trigger each customer-data flow, search the resulting logs for known personal values, then redact fields at the logging boundary and repeat the test. Apply it across the project, run the relevant checks, and show the diff.

No privacy page is linked

Payment providers, app stores, and several privacy laws expect a reachable privacy page before you take anyone's details.

Fix prompt

Create a real privacy policy page at /privacy and link it from the footer on every page. It must cover what data the app collects, why, how long it is kept, who it is shared with, and how to request deletion, written for this specific app with no placeholder text and no lorem ipsum. Match the existing page components and add the footer link. Show me the diff and the rendered route.

No terms page is linked

Without stated terms you have no written basis for suspending misuse or limiting your liability.

Fix prompt

Create a real terms of service page at /terms and link it from the footer on every page. It must cover what the service is, acceptable use, payment and cancellation terms, limitation of liability, and governing law, written for this specific app with no placeholder text and no lorem ipsum. Match the existing page components and add the footer link. Show me the diff and the rendered route.

Review browser response headers

Explicit browser policies reduce avoidable exposure and make deployment behavior easier to inspect.

Fix prompt

This app sends no Content-Security-Policy header. Add one at the response layer with default-src 'self', object-src 'none', base-uri 'self', frame-ancestors 'none', plus the exact origins the app loads, using a nonce for inline scripts. Start report-only, clear the console on every route, then enforce. Show me the policy.

Source maps are published next to the app code

Anyone can rebuild your original files, including comments, file names, and any logic you assumed was hidden.

Fix prompt

A production source map is public at {map_url} for {bundle}. Disable production source maps in the build config or stop deploying .map files, then confirm the URL 404s. Show me the config change.

Check missing and private routes

Fallback routing can return app content where a clear missing or denied response belongs.

Fix prompt

Cursor prompt: Request a missing page and each common private path in production. Return the intended missing or denied response without internal details. Apply it across the project, run the relevant checks, and show the diff.

Remove sensitive values from logs

Production logs often outlive the request that created them and may be visible to more people.

Fix prompt

Cursor prompt: Review production logging. Remove tokens, authorization headers, full request bodies, personal details, and internal error stacks from user-facing responses. Apply it across the project, run the relevant checks, and show the diff.

Review production dependencies

Unused and outdated packages increase maintenance work and can change deployment behavior.

Fix prompt

Cursor prompt: List production dependencies, remove unused packages, review reported issues, and run the existing test and build commands after each change. Apply it across the project, run the relevant checks, and show the diff.

Keep privileged Supabase work on the server

Privileged reads and writes need an authenticated server boundary.

Fix prompt

Cursor prompt: Review every privileged Supabase read and write. Keep it inside an authenticated server function and test the function with two accounts. Apply it across the project, run the relevant checks, and show the diff.

Match Supabase grants to row policies

A row policy cannot help when the intended role lacks table access, and broad grants expand exposure.

Fix prompt

Cursor prompt: Review table grants and row policies together. Grant only the operations each role needs, then test allowed and denied requests through the app. Apply it across the project, run the relevant checks, and show the diff.

Test session expiry

Expired sessions must stop protected work and return people to a recoverable sign-in state.

Fix prompt

Cursor prompt: Expire a session during a protected read and write. Confirm access stops, unsaved input is preserved where possible, and sign-in returns to the intended page. Apply it across the project, run the relevant checks, and show the diff.

Define personal-data retention

Keeping personal data without a time limit increases operational and privacy obligations.

Fix prompt

Cursor prompt: List each personal field, why it is collected, its retention period, and the deletion job or manual process that enforces that period. Apply it across the project, run the relevant checks, and show the diff.

Review caching boundaries

Private or personalized responses must not be reused for another visitor.

Fix prompt

Cursor prompt: Inspect caching for HTML, API responses, and service workers. Exclude authenticated, payment, and personal-data routes from shared caches. Apply it across the project, run the relevant checks, and show the diff.

Review the Cursor or Claude Code release boundary

Generated and agent-edited code still needs an explicit production review.

Fix prompt

Cursor prompt: Review the production build, server and browser boundary, environment values, and generated routes. Record every observed difference from preview. Apply it across the project, run the relevant checks, and show the diff.

Review Cursor or Claude Code changes before publishing

A focused diff review catches unrelated generated changes before they reach production.

Fix prompt

Cursor prompt: Review the full release diff. Remove unrelated changes, confirm each changed file has an owner, and run the checks affected by that diff. Apply it across the project, run the relevant checks, and show the diff.

Record Cursor or Claude Code release evidence

A dated record makes regressions and rollback decisions easier to explain.

Fix prompt

Cursor prompt: Record the release commit, production URL, test time, owner, observed result, and rollback reference for this launch. Apply it across the project, run the relevant checks, and show the diff.
