143-145: Good addition for configuration visibility.The
log_useful_infomethod provides useful debugging information about loaded models and version status immediately after configuration loading.Minor style improvement needed.
Add proper spacing between methods according to PEP 8 conventions.

4-4: Good addition for performance optimization.Adding the
@cachedecorator import supports the memoization strategy for CLI startup optimization.
9-9: Verify timeout reduction doesn't cause excessive failures.The timeout was reduced from 2 seconds to 0.3 seconds, which is quite aggressive. While this improves CLI startup speed, it may cause more failures on slower networks.
Consider monitoring failure rates after this change, especially in environments with higher network latency. You might want to make this configurable or find a balance between speed and reliability.
17-17: Excellent use of caching for CLI performance.The
@cachedecorator prevents redundant network calls during CLI execution, which aligns perfectly with the PR objective to speed up CLI startup.holmes/__init__.py (2)
5-5: Good addition for performance optimization.Adding the
@cachedecorator import enables memoization of expensive operations.
15-15: Perfect candidate for caching.The
@cachedecorator onget_version()is an excellent optimization. This function performs expensive subprocess calls and file I/O that don't need to be repeated during a single CLI execution.holmes/config.py (2)
174-182: Well-structured config loading with logging.The refactored approach properly instantiates the config object first, then calls
log_useful_info()before returning. This ensures immediate visibility of loaded configuration details.
212-214: Consistent logging implementation.Good consistency with the
load_from_filemethod by callinglog_useful_info()after config instantiation.

@mainred do you mind re-approving? (nothing substantial changed, but I had to resolve a merge conflict so the review is stale) |

16-16: LGTM: Caching prevents duplicate expensive network calls.The caching decorator addresses the issue where
model_post_initis called twice in certain flows, preventing duplicate expensive network calls. This change was previously discussed and confirmed safe for both CLI and server usage.

24-24: Consider the trade-off between performance and observability.Commenting out the logging statement improves performance but reduces observability when API calls fail. This aligns with the CLI startup speed objective, but consider whether this information might be valuable for debugging connectivity issues.
If debugging information is needed, consider using a debug-level log instead of removing it entirely:
- # logging.info("Failed to fetch holmes info") + logging.debug("Failed to fetch holmes info")

3-3: LGTM: Import addition supports caching functionality.The import is necessary for the
@cachedecorator and is correctly placed.
8-8: Verify the timeout reduction is sufficient for typical conditions.The timeout was reduced from 2 seconds to 0.3 seconds, which is quite aggressive. While this supports the CLI startup speed improvement goal, ensure this timeout is sufficient for typical network conditions and API response times to avoid unnecessary failures.
Consider monitoring for timeout-related failures after deployment, especially in environments with higher network latency.
