CI Integration

Example GitHub Actions workflow for a docs or skills hub:

name: Publish Index

on:
  push:
    branches: [main]

jobs:
  publish:
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
      - uses: actions/checkout@v4

      - name: Install agentctl
        run: |
          curl -sSL https://github.com/geronimo-iia/agentctl/releases/latest/download/x86_64-unknown-linux-gnu.tar.gz | tar xz -C /usr/local/bin

      - name: Validate
        run: agentctl hub validate --type docs --path .

      - name: Generate index.json
        run: agentctl hub generate --type docs --path . --output index.json

      - name: Commit index.json
        run: |
          git config user.name "github-actions[bot]"
          git config user.email "github-actions[bot]@users.noreply.github.com"
          git add index.json
          git diff --staged --quiet || git commit -m "chore: regenerate index.json [skip ci]"
          git push

Replace --type docs with --type skills for a skills hub.
