Domain Registry Initializer

Initialize or refresh the Domain Registry in this project's CLAUDE.md.

What This Does

1. Scans the project for library/domain directories
2. Reads each library's metadata (project.json, package.json, or ng-package.json)
3. Writes (or updates) a ## Domain Registry section in CLAUDE.md
4. Adds the auto-load instruction if it's not already present

Instructions

Step 1 — Detect Project Structure

Run the detection script to find all library directories:

bash .claude/skills/domain-init/scripts/scan_domains.sh 2>/dev/null \
  || node .claude/skills/domain-init/scripts/scan_domains.js 2>/dev/null

If neither script is available, scan manually:

• Look for directories under libs/ that contain project.json or package.json
• For Nx workspaces: read project.json → name and targets.build.options.project
• For plain npm: read package.json → name
• For Angular libraries: read ng-package.json → check parent package.json for name

Step 2 — Build the Registry Table

For each found library, collect:

Generate description heuristics if no README exists:

• widget-* → "Widget: [name] feature module"
• *-domain or domain → "Domain layer: business logic and state"
• *-feature or feature → "Feature layer: container components"
• *-ui or ui → "UI layer: presentational components"
• *-util or util → "Utilities and helpers"
• shared/* → "Shared: [name]"

Step 3 — Write to CLAUDE.md

Read the current CLAUDE.md. Then:

If <!-- domain-registry-start --> already exists: Replace everything between the start and end markers with the new table.

If it does not exist: Append the following block to CLAUDE.md:

## Domain Registry

> Auto-maintained by domain-init skill. Run `/domain-init` to regenerate.

<!-- domain-registry-start -->
| Path | Import Path | Description |
|------|-------------|-------------|
| <path> | <import-path> | <description> |
<!-- domain-registry-end -->

Step 4 — Add Auto-Load Instruction (if missing)

Check if CLAUDE.md already contains the phrase domain-init skill or Domain Registry. If it does NOT, also append:

## Domain Context Loading

The `domain-init` skill is active. Before working on any library listed in the
Domain Registry above, silently read its `README.md` for architecture context.

Step 5 — Report

After writing, output a summary:

✓ Domain Registry updated in CLAUDE.md
  Found N domains:
  - libs/widget-chat  →  @scope/widget-chat
  - libs/shared/...   →  @scope/shared/...
  ...

  Domains without README.md (consider running /domain-readme <path>):
  - libs/dashboards-manager
  - libs/widget-map

Arguments

$ARGUMENTS — optional scan root path. Defaults to libs/ if empty.

Examples:

• /domain-init — scans libs/
• /domain-init libs/shared — scans only libs/shared/
• /domain-init packages — scans a packages/ monorepo structure

Re-running

This skill is idempotent. Running it multiple times only updates the registry table, preserving all other content in CLAUDE.md.
