What changed

Resource 3tg://spec/syntax was removed, consumers reading it will break. Resource 3tg://template/project-agents-md was removed, consumers reading it will break.

What to do

If your agents call mcp.3tg.dev, pin the new snapshot, patch the affected call sites, and let a green contract check confirm the fix. If you don't use the changed tools, nothing is required, but the rest of the ecosystem just learned about it at the same moment you did.
