Test all healthy registered agents by sending A2A message/send requests and set maintainer notes based on the results.

Run the send_messages script from client-python/:
cd client-python && uv run --extra all python examples/send_messages.py
This tests all healthy conformant agents with >90% uptime. For broader coverage, modify the filter in the script.
Classify each agent into one of these categories based on the test output:
| Category | HTTP/Error | Note Template |
|---|---|---|
| Working | Got a text response | Verified working. Agent responds to \message/send` correctly via A2A SDK.` |
| 404 Not Found | 404 on message/send | A2A endpoint returns **404 Not Found** when sending messages. The agent card is served correctly but the \message/send` endpoint does not exist at the expected URL.` |
| 405 Method Not Allowed | 405 on message/send | Agent card is valid but the A2A endpoint returns **405 Method Not Allowed**. Ensure your server accepts POST requests for \message/send` at the URL in your agent card.` |
| 401 Unauthorized (no standard auth) | 401, no securitySchemes | Agent requires authentication (returns **401 Unauthorized**) but does not declare \securitySchemes` / `security` in the agent card. See the A2A spec for the correct format.` |
| 401 Unauthorized (proper auth) | 401, has securitySchemes | Agent requires authentication (returns **401 Unauthorized**). The agent card correctly declares \securitySchemes` — callers need valid credentials.` |
| Non-compliant response | ValidationError from SDK | Agent responds but the response is missing required A2A fields. The response cannot be parsed by standard A2A SDK clients. Update your response format to match the latest A2A spec. (include specific missing fields) |
| No compatible transports | ValueError: no transports | Agent card does not declare any compatible A2A transports. The A2A SDK cannot connect. |
| DNS failure | nodename not provided | Agent card URL fails DNS resolution — the host appears to be down or decommissioned. |
| Timeout | ReadTimeout | Agent endpoint is reachable but times out when processing \message/send` requests.` |
For 401 agents, check if they declare auth properly:
curl -s "<wellKnownURI>" | python3 -c "
import json, sys
d = json.load(sys.stdin)
print('securitySchemes:', d.get('securitySchemes', '(none)'))
print('security:', d.get('security', '(none)'))
# Also check non-standard fields
for k in d:
if 'auth' in k.lower():
print(f'{k}:', d[k])
