If
service domain addfails with 422 on staging, the “Add the domain” action omits--branch. A user who fills in<name>and runs that command targets production. If production has a live service with that name, the command can register the hostname on the wrong service. Pass the resolved branch into domain error construction and include it in recovery commands, including the DNS recovery command at line 636.🤖 Prompt for AI Agents

Use the API recovery hint for custom-domain quota errors so an hourly creation limit tells users to wait instead of deleting a domain. Verified root format, types, lint, error reference, the full CLI package suite, and local end-to-end tests. Live API tests skip without a token. Root pnpm test stops at an unchanged cli-engine prompt timeout that also reproduces in isolation; pnpm --filter @prisma/cli test passes.

Address the CodeRabbit finding by carrying the supplied branch through hostname and timeout validation. Quote it in recovery commands before target selection. Cover all five domain commands and keep omitted-branch guidance unchanged.
## Purpose of change Show TXT ownership instructions, Cloudflare proxy recovery, and a safe retry command when a custom domain cannot connect. ## What's changed and why - Recognize `domain-ownership-required` as `SERVICE.DOMAIN_OWNERSHIP_REQUIRED`, with the exact DNS instructions from the API. - Keep the selected project, service, and shell-quoted branch in **Verify and connect** recovery. Do not suggest deploying the service to fix missing ownership proof. - Recognize `domain-cloudflare-proxy` as `SERVICE.DOMAIN_CLOUDFLARE_PROXY`. Explain DNS only during setup, then Proxied after Active with Full (strict) TLS and an accessible ACME challenge path. Preserve the same project, service, and branch when retrying. - Update command help and product/error docs. The CLI stays compatible with the current API and needs no SDK change. Stacked on #354 for branch-domain support. Companions: [platform #5785](prisma/pdp-control-plane#5785) and [docs #8581](prisma/web#8581). Merge and release that PR first. Release this change before the platform TXT enforcement for clear recovery guidance; publish the companion public docs only after the platform deploy and CLI release. <!-- cli-domain-verification-terminal-examples:start --> ## Terminal examples Captured from this PR's head (`231634ad916894ce495d57afaa24afc7ea11382f`) using the in-process CLI harness and synthetic API responses. ANSI colors are removed. These are actual CLI-rendered errors, not live DNS or certificate tests. `workspace-proof` is a fixture value: use the exact TXT value provided for your workspace. ### Missing workspace TXT proof The CLI shows the API's exact TXT instructions. The recovery command keeps the selected project, service, and shell-quoted branch; it does not suggest deploying the app to fix missing proof. ```console $ prisma service domain add staging.example.com --project acme-app --service hello-world --branch 'feature/domain fix' ✘ [SERVICE.DOMAIN_OWNERSHIP_REQUIRED] Verify ownership of staging.example.com why: DNS does not contain the TXT proof for this workspace. → Add a TXT record named _prisma-verification.staging.example.com with value prisma-verification=workspace-proof. Keep this record to reconnect domains in this workspace, then retry the same command. → Verify and connect: prisma service domain add staging.example.com --service svc_staging --project proj_1 --branch 'feature/domain fix' ``` Exit status: `2`. JSON mode reports `SERVICE.DOMAIN_OWNERSHIP_REQUIRED` and the same **Verify and connect** next action. ### Cloudflare proxy recovery Connect with **DNS only**, wait for **Active**, then restore **Proxied** with **Full (strict)** TLS. The instructions also cover the ACME challenge path for certificate renewal. ```console $ prisma service domain add staging.example.com --project acme-app --service hello-world --branch 'feature/domain fix' ✘ [SERVICE.DOMAIN_CLOUDFLARE_PROXY] Turn off Cloudflare's proxy to connect staging.example.com why: Failed to add custom domain: This hostname appears to use Cloudflare's proxy. Set this record to DNS only (gray cloud). Once the domain is Active, turn Proxied back on with Full (strict) SSL/TLS and keep /.well-known/acme-challenge/* accessible. → Set this record to DNS only (gray cloud). Once the domain is Active, turn Proxied back on with Full (strict) SSL/TLS and keep /.well-known/acme-challenge/* accessible. → Verify and connect: prisma service domain add staging.example.com --service svc_staging --project proj_1 --branch 'feature/domain fix' ``` Exit status: `2`. JSON mode reports `SERVICE.DOMAIN_CLOUDFLARE_PROXY`. Both captured recovery commands keep `--project proj_1`, `--service svc_staging`, and `--branch 'feature/domain fix'`. <!-- cli-domain-verification-terminal-examples:end --> ## Testing notes / Before-after Before: the ownership error would be mistaken for a missing deployment. After: the CLI shows the workspace TXT instructions or Cloudflare-specific recovery and retries the same branch app. Passed: root format, type checks (nine tasks), lint, error-reference completeness (132 codes), full CLI package suite (1,050 passed, one existing skip), and local end-to-end tests (seven passed). The 48 live API tests skip without a service token. No live DNS or TLS changes were made.
Purpose of change
Let users manage custom domains on preview and staging branches through
service domain --branch <name>.What's changed and why
--branchis omitted.SERVICE.BRANCH_NOT_DEPLOYABLEerror.Companion changes: Console and domain support and public docs. The REST API already accepts branch apps; the Console restriction is removed by the platform PR. Publish the docs after the platform change is deployed and this CLI change is released.
Terminal examples
Captured from this PR's current head (
54b4ea48389004d000508070c0ca1c05a1f57d43) with the in-process CLI harness and synthetic API responses. ANSI colors are removed. These are actual CLI-rendered examples, not live DNS or certificate tests. The successful fixture assumes the required DNS records already exist. TXT/Cloudflare-specific CLI guidance is a separate change in #370.Add and wait on staging
--branchselects the app for each invocation. Keep the same selectors on follow-up commands; omitting--branchstill defaults to production.Both commands exit with status
0. Thebranch: stagingrow confirms the selected branch.DNS recovery keeps the selected branch
A branch name with spaces is quoted in the recovery command. The command also carries the resolved project and service IDs, so retrying targets the same app.
Exit status:
2.The hourly budget gives wait guidance
The API's recovery hint tells users to wait. Deleting an existing domain does not restore the hourly creation budget.
Exit status:
2.Testing notes / Before-after
Before: any domain command with a preview branch failed before calling the API. After:
prisma service domain add staging.example.com --service web --branch stagingtargets that branch's app.Passed:
pnpm typecheck(nine tasks),pnpm format,pnpm lint, andpnpm check:error-reference.Root
pnpm testand a serial retry stop at the unchanged CLI-engine test “consent with a token: a wrong answer re-prompts instead of failing” after its five-second timeout. That test also fails in isolation, without loading the changed CLI command code. The full changed CLI package suite passes separately.API calls are exercised through the in-process CLI test harness. Live DNS and TLS issuance were not exercised.
