Docs: clarify agent tag format and registration schema #13
Description
Summary
The README shows agent registration with tag: {1, 3, 4} and mentions combinations like 1+4, but the exact tag format and parsing rules are unclear.
Proposal
- Define a canonical tag representation (e.g., array of ints, array of strings, or string expression)
- Clarify whether
1+4means set union, a composite tag, or a routing hint - Add 2-3 examples of valid registrations
Why
Clear rules reduce invalid agent registrations and improve agent selection consistency.
