Review: a2a-sdk <0.3.0 → <0.4.0
Widening the constraint is safe in intent but premature — the agent code uses the camelCase API removed in 0.3.0, and includes a manual route workaround that conflicts with 0.3.x built-in behavior. The uv.lock still pins 0.2.5 so uv sync won't break today, but any lock refresh pulls 0.3.25 and breaks the agent.
Issue 1 — camelCase field access removed in 0.3.0
a2a-sdk 0.3.0 removed __getattr__/__setattr__ camelCase aliases from types.py (#335). The agent code still uses camelCase:
| Location | camelCase | Required |
|---|---|---|
__main__.py |
AgentCapabilities(pushNotifications=True) |
push_notifications=True |
__main__.py |
AgentCard(defaultInputModes=..., defaultOutputModes=...) |
default_input_modes, default_output_modes |
agent_executor.py |
task.contextId (×4) |
task.context_id |
Migration script: https://github.com/a2aproject/a2a-samples/blob/main/samples/python/refactor_camel_to_snake.sh
Issue 2 — Duplicate route conflict in 0.3.x
__main__.py manually inserts /.well-known/agent-card.json as a workaround for 0.2.x. In 0.3.0+ this path is served natively by the SDK (#352). The manual app.routes.insert(...) block must be removed before widening the constraint.

a2a-sdk 0.3.0 removed camelCase field access from types.py. The agent uses pushNotifications, defaultInputModes, defaultOutputModes (constructors) and task.contextId (attribute access) — all break with 0.3.x. Migrate with the refactor script before widening this constraint.
Migrate camelCase fields to snake_case and remove manual agent-card route workaround (now built into SDK >= 0.3.0): - AgentCapabilities: pushNotifications -> push_notifications - AgentCard: defaultInputModes/defaultOutputModes -> snake_case - Remove manual /.well-known/agent-card.json route insertion - task.contextId -> task.context_id in agent_executor.py Signed-off-by: Paolo Dettori <dettori@us.ibm.com>
Update all task.contextId attribute accesses to task.context_id to comply with a2a-sdk 0.3.x API (camelCase access removed). Signed-off-by: Paolo Dettori <dettori@us.ibm.com>
InMemoryPushNotifier was removed in a2a-sdk 0.3.0. Replace with InMemoryPushNotificationConfigStore + BasePushNotificationSender. Signed-off-by: Paolo Dettori <dettori@us.ibm.com>
Update all task.contextId attribute accesses to task.context_id to comply with a2a-sdk 0.3.x API (camelCase access removed). Signed-off-by: Paolo Dettori <dettori@us.ibm.com>
In a2a-sdk 0.3.x, starlette and sse-starlette became optional dependencies under the [http-server] extra. Update the dependency specifier accordingly. Signed-off-by: Paolo Dettori <dettori@us.ibm.com>
