Scheme 2: Core + Data Repo (Core-First)

Goal: keep the full skills/** archive browsable on GitHub, while keeping pipeline authority and automation in registry-core.

Repo Roles

1) registry-core (source of truth)

Contains:

• Crawlers + build scripts (scripts/, crawler/)
• Source lists (sources/)
• Schemas (schema/)
• Published metadata (registry.json)
• GitHub Pages site sources (docs/)
• Authoritative workflows and sync policy

Does not commit:

• The expanded skill archive skills/** (stored in registry-data)

2) registry-data (archive store)

Contains:

• archived skill contents (category folders like development/, documents/, data/, etc.)

3) registry-main (publish artifact)

Contains:

• merged tree built from core + data for browsing/compatibility consumers

Policy:

• main is not canonical for pipeline behavior.
• If docs/workflows conflict between repos, core wins.

Sync Model (Single Writer)

1. Only core runs scheduled discovery/download/sync jobs.
2. core checks out registry-data into ./skills/ during CI and updates archive/index outputs.
3. core pushes archive changes to registry-data and index/site outputs in core.
4. core can trigger a main publish workflow using pinned core_sha + data_sha.
5. main rebuilds merged outputs from those SHAs for reproducibility.

Avoid:

• Running crawler/sync schedules in main
• Letting main write to data
• Publishing metrics without clear raw vs deduplicated labels

Required CI Configuration (Core Repo)

• Repository variable: REGISTRY_DATA_REPO (e.g. yourname/claude-skill-registry-data)
• Secret: DATA_REPO_TOKEN (PAT with repo scope for private or public_repo for public)
• Repository variable: REGISTRY_MAIN_REPO (e.g. yourname/claude-skill-registry)
• Secret: MAIN_REPO_TOKEN (token that can dispatch workflows in main repo)

Local Merge (core + data -> main)

Use the merge script to rebuild the main repo from core + data:

bash scripts/sync_main_repo.sh \
  --core ../claude-skill-registry-core \
  --data ../claude-skill-registry-data \
  --main ../claude-skill-registry
