Summary by CodeRabbit

I'm unable to create meaningful release notes from this summary. The provided information is insufficient—it indicates a single line was added to a file, but offers no context about the functional impact or end-user-visible changes.

To craft effective release notes, I would need details about:

• What feature or functionality was added/modified
• How this affects end-users
• Any behavioral changes

Please provide a more descriptive summary of the actual changes made.

A single line hops into view,
Where emptiness once held sway,
One tiny change, a morning dew,
A bunny's work for the day! 🐇✨

🚥 Pre-merge checks | ✅ 1 | ❌ 4

❌ Failed checks (2 warnings, 2 inconclusive)

Check name	Status	Explanation	Resolution
Description check	⚠️ Warning	The PR description lacks required sections; it only contains 'Fixes #15' and an automation note, missing Summary, Changes, Testing, and Checklist sections.	Fill in all required template sections: describe what was changed, list code changes, document testing performed, and complete the checklist.
Linked Issues check	⚠️ Warning	The provided diff shows only one line added to 'path/to/file' with no observable functional changes, whereas issue #15 requires retry logic, circuit breaker pattern, configuration flags, result aggregation, logging, and unit tests.	Implement all required features specified in #15: retry mechanism, circuit breaker, config flags, result aggregation, proper logging, and at least 5 unit tests.
Title check	❓ Inconclusive	The title is truncated and incomplete; it contains '[Python] Add retry/backoff and c' instead of the full requirement to add circuit breaker functionality.	Provide the complete PR title without truncation to clearly describe both retry/backoff and circuit breaker features.
Out of Scope Changes check	❓ Inconclusive	The diff provided is too minimal to assess scope comprehensively, showing only a single-line addition to an unspecified file without clear functional context.	Provide a complete diff of all changed files to properly validate that modifications align with issue #15 requirements and contain no unrelated changes.

- Line 1: The health_check.py implementation is missing resilience mechanisms
and comprehensive test coverage. Add retry and exponential backoff logic to each
health check function (for HTTP, TCP, certificate, disk, memory, and load
checks) to handle transient failures gracefully, implement a circuit breaker
pattern to prevent cascading failures when services are down, and enhance
logging by adding WARNING-level log statements when health checks detect
degraded states (not just critical failures). Additionally, create integration
test files that validate the retry behavior, circuit breaker
activation/deactivation, warning log output for degraded states, and the overall
health check command behavior with various failure scenarios using the CLI flags
(--service, --json, --watch).

Health check implementation exists but lacks resilience and test coverage.

The tools/health_check.py file is a functional 351-line implementation with HTTP/TCP/certificate/disk/memory/load checks, JSON output, and CLI flags (--service, --json, --watch). However, it's missing key requirements from the bounty scope:

• No retry/backoff logic in health check functions (single attempt per check)
• No circuit breaker pattern for cascading failures
• No WARNING-level logging for degraded health states
• No test files in the repository for health_check

While the core tool exists, add resilience (retry/backoff on transient failures, circuit breaker), enhance logging (log degraded checks at WARNING level), and include integration tests before merging.
