What we found when we checked every ERC-8004 agent on Arbitrum

of valid registration documents declare no way to reach the agent — no services entry at all, or one with nothing in it.

41 / 1,132 documents that parsed and reached check 4 (Follows the spec?)

of registration files never say which on-chain agent they belong to — the spec only recommends the field that would bind them. Check 5 (Claims its identity?) records those as unclaimed: neither a pass nor a fail.

1,088 / 1,117 documents that passed check 4 (Follows the spec?) (conformant)

have at least one on-chain feedback entry. Agents with feedback are less likely to have a document that resolves than agents with none — 98.8% against 96.1%.
