fix: classify create telemetry outcomes

[AmanVarshney01]

Summary

Fixes the telemetry gaps exposed by the first ~22 hours of create-prisma@0.10.0:

• records prompt cancellation as a separate terminal outcome instead of a technical failure
• records the exact cancelled prompt without recording the selected value
• replaces the broad prisma_setup bucket with precise setup and deployment stages
• adds a safe normalized failure-reason to every technical failure
• preserves the real deployment error through the normal human-readable path instead of swallowing it
• keeps raw error messages, paths, project/workspace names, emails, and credentials out of telemetry
• marks all new events/properties with telemetry-schema-version: 2

Dashboard: https://us.posthog.com/project/60295/dashboard/2038941

Why

The initial 0.10.0 snapshot showed:

• 34.6% technical success after manually excluding prompt abandonment
• 66.1% local-only success versus 8.1% with deployment enabled
• 0 successful Windows deployments in the sample
• all post-context failures reported as prisma_setup
• most deployment-intent failures missing actionable metadata

The CLI could identify that deployment was unhealthy, but not whether auth, workspace selection, project lookup, build, migration planning, or Composer deployment was responsible.

Event model

Existing completed and failed event names remain stable.

Cancelled

cli:create_prisma_next_command_cancelled

Adds cancellation-stage with one of:

• project_name
• template
• database_provider
• authoring_style
• package_manager
• deployment_intent
• select_workspace

Failed

Adds failure-stage and failure-reason. Stages now distinguish:

• input/context/template scaffolding
• Prisma initialization and project configuration
• dependency and agent-skill installation
• contract emit and migration planning
• Git initialization
• authentication and workspace selection
• project-name lookup
• build
• Composer deploy

Reasons are a closed, non-sensitive taxonomy such as not_authenticated, workspace_mismatch, project_name_collision, build_failed, and composer_deploy_failed. Existing error-name and error-code remain supplemental; raw messages are never sent.

Error propagation

deployNewProjectWithComposer now returns a discriminated success/failure/cancellation result. Human and --json modes therefore report the same underlying failure while telemetry receives the exact stage and normalized reason.

The structured JSON failure stage is now precise as well—for example, an unavailable Prisma CLI reports initialize_prisma instead of prisma_setup.

Verification

• bun run typecheck
• bun run check
• bun run build
• bun run test:unit — 42 passed
• bun run test:e2e — 7 passed

The E2E suite covers generated Prisma Postgres, Next.js with a TypeScript contract, Deno, unsupported combinations, deterministic JSON, and classified setup failure output.

Summary by CodeRabbit

• Bug Fixes

  • Improved project creation and deployment error handling with clearer failure stages and reasons.
  • Cancellations during prompts and setup are now reported distinctly from failures.
  • Deployment/authentication errors are no longer silently ignored; non-interactive auth failures now surface correctly.

• Telemetry

  • Added cancellation tracking and standardized structured failure metadata.
  • Updated completion events to use schema version 2, with sensitive error details excluded.

Walkthrough

The create workflow adds shared failure stages, failure reasons, cancellation stages, and typed errors. Composer deployment and Prisma setup now return structured success, cancellation, and failure results. Prompt cancellations propagate as cancellation outcomes. Validation, scaffolding, authentication, setup, build, and deployment errors retain classified metadata. Telemetry records schema version 2, failure reasons, and cancellation events. Tests cover classified authentication failures, setup stages, sanitized failure telemetry, and prompt cancellation.

Merge Risk: ⚪ Minimal · up to 7b4d9

The PR improves classification and propagation of create-command outcomes while keeping telemetry data normalized and non-sensitive; no actionable merge-blocking risk remains beyond normal checks and review.

- Around line 309-320: Update the CreateCancellationError branch in the create
command to pass error.stage to createCommandFailureResult instead of
failureStage, keeping telemetry and the existing result fields unchanged.

Apply the same fix in `@src/result.ts` at line 21: The result-stage type must
accept cancellation stages so the precise stage can be preserved in JSON output.
