Code Review
This pull request introduces a unified SessionInfo schema to standardize session metadata across different managed agent backends, including the addition of a SessionInfo dataclass and updates to the retrieve_session methods. Review feedback identified a logic error in the SessionInfo post-initialization that could result in incomplete usage data, an inconsistency in status strings for local agents compared to the Anthropic implementation, and a need for safer attribute extraction to handle explicit null values from API responses.

There was a problem hiding this comment.
Using "none" as the status when no session exists is inconsistent with the AnthropicManagedAgent implementation, which returns "unknown" (the default in SessionInfo) in the same scenario. Furthermore, the updated test test_retrieve_session_no_session in test_managed_backend.py explicitly asserts that the status should be "unknown". This inconsistency will cause that test to fail when running against the local backend.

There was a problem hiding this comment.
The elif logic in __post_init__ is flawed. If both input_tokens and output_tokens are missing from the usage dictionary (for example, if usage={} is passed), only input_tokens will be initialized because the elif chain will stop after the first match. This results in an incomplete usage dictionary, which contradicts the goal of a unified schema where all fields are always present.

There was a problem hiding this comment.
Using getattr(sess, "status", "unknown") (and similar for title) can return None if the attribute exists on the sess object but its value is explicitly None (which is common in API responses for optional fields). Since the SessionInfo dataclass hints these fields as str, receiving None might cause issues for consumers expecting string methods (e.g., .lower()). It is safer to use or to ensure the default value is applied when the attribute value is falsy.

- Around line 186-201: The test test_empty_session_local is asserting a
backend-specific status ("none") instead of the canonical schema; update it to
match the Anthropic test expectations by asserting the same defaults produced by
SessionInfo().to_dict() (e.g., status "unknown", id "", title "", and usage
{"input_tokens": 0, "output_tokens": 0}) so LocalManagedAgent.retrieve_session()
and test_empty_session_anthropic use identical schema assertions; locate the
test function test_empty_session_local and replace the status and related
assertions to mirror test_empty_session_anthropic (or assert equality against
SessionInfo().to_dict()).
In `@src/praisonai/praisonai/integrations/_session_info.py`:
- Around line 32-39: The __post_init__ method in SessionInfo currently uses an
elif chain that prevents adding "output_tokens" when both keys are missing;
update SessionInfo.__post_init__ to initialize usage with defaults using
independent checks or usage.setdefault for both "input_tokens" and
"output_tokens" (e.g., if self.usage is None: set full default dict, else call
self.usage.setdefault("input_tokens", 0) and
self.usage.setdefault("output_tokens", 0)) so both keys are guaranteed; add a
unit test constructing SessionInfo(usage={}) and asserting both tokens exist
with 0 to prevent regression.
In `@src/praisonai/praisonai/integrations/managed_agents.py`:
- Around line 593-599: The SessionInfo construction uses getattr(sess, "status",

that exist but are None; update the coercion to treat None as the default by
using expressions like (getattr(sess, "status", None) or "unknown") and
(getattr(sess, "title", None) or "") and similarly ensure the id uses
(getattr(sess, "id", None) or self._session_id) so SessionInfo(id=...,
status=..., title=...) always receives non-None strings; leave usage_dict
handling as-is and then return session_info.to_dict().

session exists; change SessionInfo construction in retrieve_session so id uses
an empty string when self._session_id is falsy (e.g. id=self._session_id or "")
and status uses "idle" when there is a session else "unknown" (e.g.
status="idle" if self._session_id else "unknown"), keeping usage the same and
then return session_info.to_dict(); also update the corresponding test
(test_empty_session_local) to assert id == "" and status == "unknown".

SessionInfo.post_init uses an elif chain when filling missing token keys, so usage={} will only get input_tokens and still miss output_tokens. This contradicts the stated invariant that both token fields are always present. Consider normalizing with two independent checks (or setdefault) after ensuring usage is a dict. Also, usage is annotated as Dict[str, int] but defaults to None; update the type to Optional[Dict[str, int]] (or use field(default_factory=...)) to avoid type inconsistencies.

LocalManagedAgent._session_id is declared as Optional[str] and is initialized to None, but retrieve_session() passes it straight into SessionInfo as id=self._session_id. When no session exists this will return {"id": None, ...} rather than the unified schema's string default. Coerce id to an empty string (e.g., self._session_id or "") or have SessionInfo normalize id=None to "" in post_init.

This implementation returns status="none" when there is no session, while the unified SessionInfo defaults (and the Anthropic backend's no-session behavior) use status="unknown" per the #1429 acceptance criteria. To keep schema semantics consistent across backends, align the no-session status value (or document/encode backend-specific statuses explicitly if intentional).

test_schema_equality_between_backends claims to validate equality between Anthropic and Local backends, but it only exercises LocalManagedAgent and checks its keys. This won't catch drift between implementations. Consider either (1) mocking AnthropicManagedAgent similarly to test_anthropic_retrieve_session_schema and asserting the two dicts have identical key sets + value types/defaults, or (2) renaming the test to reflect what it actually verifies.

This test constructs ManagedAgent(api_key="test-key") without forcing provider="anthropic" or patching ANTHROPIC_API_KEY/CLAUDE_API_KEY. Since ManagedAgent() auto-detects provider based on environment variables (and does not currently switch to Anthropic just because api_key is passed), this assertion can fail in environments where those env vars are unset (it would return LocalManagedAgent, which reports a different no-session status). Make the test deterministic by either passing provider="anthropic" or patching the env vars in this test.
