Summary

  • Discover Capacitor apps from package-manager workspaces during direct npx @capgo/cli@latest build init onboarding.
  • Confirm the detected app when exactly one candidate exists, or let the user select when several apps are found.
  • Keep discovery bounded to the invocation root and workspace packages—never search parent directories or crawl arbitrary descendants.
  • Explain unsupported Nx-only layouts while still supporting Nx repositories that expose standard package workspaces.

Why

Builder onboarding previously loaded the Capacitor configuration only from the current working directory. Running build init from a monorepo root therefore failed before the user could choose the actual Capacitor app.

Impact

Direct builder onboarding now uses @manypkg/tools metadata to enumerate npm, Yarn, pnpm, Bun, Lerna, and Rush workspaces. Existing behavior remains unchanged when the command starts inside a Capacitor app, and indirect onboarding callers keep their existing working-directory behavior.

Discovery requires a package.json at the invocation root, rejects candidates outside that root (including symlink escapes), and gives a focused error for Nx layouts that do not expose supported workspace metadata.

Test plan

  • bun run cli:test
  • bun run --cwd cli lint
  • bun run --cwd cli typecheck
  • bun run cli:build
  • bun cli/dist/index.js build init --help

Screenshots

Not applicable; this is a terminal-only CLI flow.

Checklist

  • My code follows the code style of this project and passes bun run lint:backend && bun run lint.
  • My change requires a change to the documentation.
  • I have updated the documentation accordingly.
  • My change has adequate E2E test coverage.

📝 Walkthrough

Walkthrough

Direct build init now discovers Capacitor projects in supported workspaces. It supports candidate selection, cancellation, path validation, Nx messaging, directory switching, configuration fallback, and focused test coverage.

Changes

Builder Init Discovery

Layer / File(s) Summary
Workspace discovery
cli/src/build/onboarding/project-discovery.ts, docs/superpowers/...
Adds workspace adapters, bounded path handling, Capacitor config detection, Nx detection, candidate deduplication, and stable sorting.
Project selection and onboarding
cli/src/build/onboarding/command.ts, cli/src/build/onboarding/project-selection.ts, cli/src/build/onboarding/ui/..., cli/src/index.ts
Enables discovery for direct build init, presents candidates, handles cancellation and failures, changes to the selected project directory, and continues onboarding.
Configuration loading compatibility
cli/src/config/index.ts
Validates TypeScript compilers and falls back to the bundled compiler when required.
Discovery validation and supporting updates
cli/test/..., cli/package.json, docs/superpowers/..., private/cli-mcp-tests
Adds fixture-based discovery tests, shell-size assertions, aggregate test wiring, design documentation, and the updated subproject reference.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f7d80

Build initialization now changes how workspace-based Capacitor projects are selected, but unresolved adapter-precedence and mixed Lerna/workspace behavior could select the wrong app in some monorepos. Merge should wait for those bounded correctness concerns to be fixed or explicitly accepted; the test submodule commit also needs reachability verification.

46-52: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Align the adapter-order specification with the implementation.

Lines 46-52 put LernaTool before Bun, Yarn, and npm. cli/src/build/onboarding/project-discovery.ts checks root workspaces first. The test at cli/test/test-builder-project-discovery.mjs line 148 also verifies that root npm workspaces take precedence when lerna.json omits package globs.

Move the Lerna fallback after the root-workspace adapters. State that Bun and Yarn markers are evaluated only when root workspaces exist. Otherwise, a later implementation can follow this design and regress discovery behavior.

Proposed specification update
-3. `lerna.json` -> `LernaTool`
-4. Bun package-manager metadata or lockfile -> `BunTool`
-5. Yarn package-manager metadata, lockfile, or object-form workspaces ->
+3. Bun package-manager metadata or lockfile with root workspaces -> `BunTool`
+4. Yarn package-manager metadata, lockfile, or object-form workspaces ->
    `YarnTool`
-6. npm metadata, lockfile, or array-form workspaces -> `NpmTool`
+5. Root workspaces without a Bun or Yarn marker, including array-form
+   workspaces -> `NpmTool`
+6. `lerna.json` without root package-manager workspaces -> `LernaTool`
