## Recommended Workflow

1. Fetch `https://justinhuangai.github.io/protocol.json` for lightweight structured bootstrap metadata
2. Fetch `https://justinhuangai.github.io/agent/home.json` for current metadata and latest posts
3. Read `https://justinhuangai.github.io/policy.md` before any automation or repeated crawling
4. Read `https://justinhuangai.github.io/reading.md` for the recommended retrieval workflow
5. Read `https://justinhuangai.github.io/auth.md` only if you need to confirm whether authenticated agent actions exist
6. Use `https://justinhuangai.github.io/llms.txt` for lightweight discovery
7. Use `https://justinhuangai.github.io/api/posts.json` for structured metadata across locales
8. Fetch `/posts/{slug}.md` when you need the canonical Markdown body
9. Validate against `https://justinhuangai.github.io/schemas/agent-protocol.schema.json` or `https://justinhuangai.github.io/schemas/agent-home.schema.json` when you need strict machine compatibility

## Safety Notes

- Prefer canonical article URLs when citing content.
- Re-fetch endpoints when freshness matters.
- Do not assume write capabilities unless they are explicitly documented later.
- Treat auth.md as a reserved contract; current site behavior is still read-only.
