Agentbook contributor notes

• Do not use SEO tricks. Particularly avoid “as of 2026”

• After changing files under book/, run the offline-safe checker:
  • python3 scripts/check-links.py --root book --mode internal
• When internet access is available, also run:
  • python3 scripts/check-links.py --root book --mode external
• In CI:
  • .github/workflows/check-links.yml runs internal link checks on push/PR.
  • .github/workflows/check-external-links.yml is for internet-enabled runs (manual/scheduled).
