fix(cli): show a module entry in deploy/dev help and link the CLI error reference

[kristof-siket]

Problem

prisma deploy --help (as published in prisma@8.0.0-rc.15) suggests prisma deploy src/service.ts. Running that against a file that default-exports a compute({...}) service fails with COMPOSE.ROOT_NOT_MODULE — The deploy root must be a module. The behaviour is right (matches the docs quickstart and prisma/cloud-deploy-action, whose module input defaults to module.ts); the help was wrong. prisma dev, destroy and log carried the same example and argument text.

The same help output ended with Docs https://docs.prisma.io/docs/orm/next/reference/error-reference (ORM docs), while every other prisma subcommand ends with Docs https://www.prisma.io/docs/cli/error-reference/. The COMPOSE.* errors' docsUrl diverged the same way.

Change

• deploy, dev, destroy, log: examples use module.ts; the entry argument now says the default export is the application root module, built with module(...).
• The composer command family's docsBaseUrl is now https://www.prisma.io/docs/cli/error-reference/, so the help footer and every COMPOSE.* docsUrl match the rest of the CLI. The foundation's DOCS_BASE/docsUrlFor are untouched: those serve the donor's ORM-side codes (CONTRACT.* etc.), whose docs live under the ORM reference.

No help-output snapshots exist for these commands, so no test changes.

Verification

• bun test src/family in 3-tooling/cli: 82 pass, 7 fail. The same 7 fail on a clean origin/main checkout in my environment (JSON-frame parse / --config loader cases, unrelated to help text), so they are pre-existing.
• biome check on the changed files: clean.

Change walkthrough

This PR fixes the help text of the four composer CLI commands and repoints their error-docs link. The deploy, dev, destroy, and log examples suggested src/service.ts, which is not what a deploy root is: the entry's default export must be a Composer Module built with module(...), matching the docs quickstart. The same help output footer linked the ORM error reference instead of the CLI one that every other prisma subcommand uses, and the composer family's docsBaseUrl was the source of that divergence.

Help text (deploy.ts, destroy.ts, dev.ts, log.ts). All four get identical wording: examples use module.ts, and the entry brief now says the default export is the application root module built with module(...). The wording is uniform across the four commands, including destroy and log, which are mounted as top-level commands of the composer bin on top of the family in engine-cli.ts rather than shipped in the family itself.

Docs link (family.ts:62). The family now passes a local CLI_DOCS_BASE (https://www.prisma.io/docs/cli/error-reference/) to the engine's docsBaseUrl, replacing the DOCS_BASE import from the foundation. The comment records that the engine appends /<CODE> to form error-envelope links.

Net diff vs the PR description. The description's "Change" section describes an intermediate state of this PR: commit 82a749b repointed the foundation's DOCS_BASE and reshaped docsUrlFor, and the final commit (cbfc131) reverted the foundation byte-for-byte — ORM donor codes like CONTRACT.* genuinely live under the ORM error reference — keeping the fix local to the composer family instead. The checked-in head contains no foundation changes, and the head commit message documents that rationale.

Summary by CodeRabbit

• Bug Fixes

  • Updated structured error links to open the CLI error reference and use the correct error-code URL format.

• Documentation

  • Updated deploy, destroy, dev, and log command examples to use module.ts.
  • Clarified that the entry file’s default export should be the application root module created with module(...).

Walkthrough

The structured error documentation URL now targets the CLI error-reference path and appends error codes as path segments. The related test expects the new URL format. The deploy, destroy, dev, and log command help text now uses module.ts examples and describes the required default-exported application root module built with module(...).

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to b8a99

Error links may point to the wrong documentation location for codes containing URL delimiters; the localized fix should be applied before merging.
