🧹 Nitpick comments (7)
tests_integration_with_local_chain/markets/omen/test_contract.py (1)
133-140: Add negative test coverage to ensure robust test validation.While the current test gracefully verifies that the
sDaiContract().get_asset_token_balance()result is non-negative, it could be beneficial to also test against edge cases (e.g., querying an invalid or non-existent address, or an address that has never transacted with the contract) to ensure the contract method handles unexpected inputs gracefully. This would solidify confidence that the integration behaves as expected in all circumstances.Below is a potential follow-up test you could include:
+def test_sdai_asset_balance_of_non_existent_address(local_web3: Web3) -> None: + # Check that an empty or non-existent address returns 0 or raises an expected exception + balance = sDaiContract().get_asset_token_balance( + Web3.to_checksum_address("0x0000000000000000000000000000000000000000"), + web3=local_web3, + ) + assert balance == 0, f"Expected 0 balance for a non-existent address, but got {balance}"prediction_market_agent_tooling/tools/contract.py (3)
541-549: Consider verifying contract address via environment configuration.Hardcoding the contract address increases the risk of accidental deployments on the wrong network. It might be beneficial to make this address configurable via environment variables or configuration files for better maintainability and flexibility.
564-574: Ensure safe handling of the raw message container structure.
get_at_indexrelies onfrom_tupleto parse the raw tuple. Consider validating the length or structure ofmessage_container_rawto avoid unexpected errors if the contract returns malformed data or changes its return signature.
597-612: Confirm message correctness and ensure robust error-handling.The
send_messagefunction sends both data and funds to the contract. Confirm that internal or external calls won't revert unexpectedly, especially for largemessagesizes or zeroamount_wei. You might add error handling or checks for contract reverts.prediction_market_agent_tooling/tools/data_models.py (1)
13-28: Validate tuple length before unpacking.While
from_tupleis straightforward, consider verifying the tuple’s length to avoid indexing errors if the contract ABI changes or returns different data.prediction_market_agent_tooling/tools/web3_utils.py (2)
97-97: Reduced retry attempts may cause transient failures.Decreasing from 5 to 2 attempts could lead to more transient call failures. Ensure external dependencies are stable enough that fewer retries won't degrade user experience.
169-169: Balance between speed and reliability.Similarly, for
send_function_on_contract_tx, having fewer retries can limit resilience to intermittent network issues or load spikes. Consider making the retry count configurable when high availability is needed.

21-24: Imports look good.
These data models are essential for typed data exchange, and importing them here keeps the contract logic self-contained.
550-563: Validate the scenario when no unseen messages exist.
While count_unseen_messages works correctly, consider adding a check or handling around scenarios where the contract call might revert for an invalid address or if something else goes wrong. Ensuring robust error handling or introducing a fallback path in the calling code might be helpful.
575-596: Verify logs before accessing them by index.
After popping a message, process_receipt(tx_receipt) may yield an empty list if the event is not emitted or fails. Safeguard with a check on log_message_raw length to avoid potential IndexError if no events match.
prediction_market_agent_tooling/tools/data_models.py (1)
30-35: Data model usage looks solid.
LogMessageEvent with populate_by_name is a tidy solution for reading contract event fields with matching aliases.
tests_integration_with_local_chain/nft_agents/test_agent_communication.py (2)
1-42: Integration tests illustrate real blockchain interactions well.
Test coverage for test_count_unseen_messages is good. You might also consider negative tests, such as sending no message or calling the function on a non-existent agent address, to confirm error-handling under edge cases.
[approve]
45-91: Comprehensive test for message retrieval.
test_pop_message thoroughly checks the retrieval flow. To strengthen coverage, test popping a message from an empty queue to confirm that the contract or library raises the expected error or handles it gracefully.

prediction_market_agent_tooling/tools/contract.py (4)
540-547: Consider making ABI path configurable.
The ABI file path is hard-coded. For robust environments, consider making this configurable or passing it as a parameter so that you can easily swap ABIs as needed during testing or across environments.
549-551: Avoid hard-coding contract address.
Hard-coding the contract address can cause maintainability issues when the contract is redeployed or changed. You may want to load this address from a configuration file or environment variable.
563-573: Validate index or handle out-of-range indexes.
The contract could revert ifidxis out of range. Consider catching or logging potential errors to improve debugging and error transparency.
605-620: Add minimal docstring or notes on behavior forsend_message.
While the usage of the underlyingsend_with_valuefunction is clear, a short docstring or inline comment explaining possible revert scenarios or usage constraints can benefit future maintainers.prediction_market_agent_tooling/tools/data_models.py (1)
1-27: Validate tuple size infrom_tuple().
You assume that the tuple will always have four elements in the correct order. Consider checking the length or using more robust parsing to avoid potential index errors.tests_integration_with_local_chain/nft_agents/test_agent_communication.py (5)
12-21: Add negative test scenario.
Intest_count_unseen_messages, you might also add a test for a nonexistent, erroneous, or invalid agent address to confirm how the system behaves.
22-28: Remove or refine commented-out code.
This code block is commented out. If it’s purely illustrative, consider adding a comment explaining its purpose or remove it to avoid confusion.
44-53: Add explicit assertion message for clarity.
When verifyinginitial_messages == 0, consider providing a short reason in the assertion to clarify the expectation in case of test failure.
54-59: Remove or refine commented-out snippet.
Similar to the prior comment, decide if this snippet can be safely removed or should be documented.
75-82: Test additional edge cases.
It could be valuable to test a scenario whereget_at_indexis called with an invalid index to confirm proper error handling.

21-23: New import for MessageContainer.
Looks good and correctly references the new model.
553-562: Add error handling for contract call failures.
When calling countMessages on the contract, consider defensively handling exceptions that might arise if the contract is unavailable or the call fails for any reason.
574-604: Check transaction success when popping messages.
Currently, the transaction receipt is silently discarded. Consider at least logging or verifying transaction success to handle any unexpected reverts or failures.
tests_integration_with_local_chain/nft_agents/test_agent_communication.py (1)
83-89: Ensure message authenticity is tested.
You’re checking that the popped message matches mock_agent_address and compressed payload. Consider also verifying logic for potential modifications or invalid data in real usage.

20-20: Clarify or remove the skipped test.The test is currently skipped with a vague reason. If the subgraph is unavailable or unstable, consider marking it as
@pytest.mark.xfailinstead and providing clearer context. Otherwise, remove the skip if the test is ready.prediction_market_agent_tooling/tools/contract.py (3)
538-550: Document the newAgentCommunicationContractclass.This class adds important communication features. While the comment at line 540 references the ABI, consider adding a dedicated docstring explaining how to instantiate and use this class, its constructor expectations, and its constraints.
561-571: Validate index bounds forget_at_index.A large or negative
idxmight cause the contract call to revert. Ensure caller code handles or prevents out-of-range indexes to avoid unexpected exceptions.
572-602: Handle empty queue scenarios inpop_message.If the queue is empty,
get_at_index(idx=0)may revert. To enhance reliability, consider implementing a safety check for zero messages before attempting to retrieve or pop.

12-12: Make parent_market usage robust when allowing None.
Changing parent_market from HexBytes to HexBytes | None is beneficial for optional usage scenarios, but please ensure any downstream references safely handle None cases to prevent potential errors or unexpected behavior.
prediction_market_agent_tooling/tools/contract.py (3)
21-21: New import is appropriately introduced.
MessageContainer is essential for handling message payloads within the new AgentCommunicationContract. Nice addition.
551-560: Check contract availability for countMessages.
Although the method looks correct, watch out for scenarios where the on-chain contract might be missing or might not implement the countMessages function. Consider verifying contract capabilities or capturing errors if the call reverts.
603-618: Consider potential transaction failures in send_message.
While this method is straightforward, the contract call might fail (e.g., if agent_address is invalid or if amount_wei is insufficient). As a safeguard, ensure calling code is prepared to handle exceptions or revert logs for better failure transparency.
