Why this order?
Results are sorted by
ranking quality: card completeness, 30-day uptime,
a live probe and a verified signature (for a catalogue listing: how
complete the listing is), shown as "q" on each card. Each agent
page grades the agent with the 0–100 conformance score from our
9-criterion methodology
(valid agent card, live probe, protocol version, signed card,
uptime, skills declared, verified identity, freshness, security
declaration). Machine-readable schema:
conformance.json.
No paid placement, no editorial weights.
