Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file). ⌛ How to resolve this issue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits. 🚦 How do rate limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly. Please see our Fair Usage Limits Policy for further information. 📝 WalkthroughWalkthrough

90-146: 🧹 Nitpick | 🔵 Trivial | ⚡ Quick winMissing logging for retry attempts and degraded services.
The
probe_with_retry()function implements retry/backoff correctly (formula, loop, status classification), but the PR objectives require "WARNING level logging for degraded services". This function has no logging output, so retry attempts, backoff delays, and degraded probe status are silent.Add
logger.warning()calls to log each retry attempt, backoff delay, and final CRITICAL status after retries are exhausted. This will help operators understand why health checks are delayed or degraded.🤖 Prompt for AI Agents

In `@shanaboo_solution.md` around lines 90 - 146, The probe_with_retry() function is missing required logging for retry attempts and degraded services. Add a logger.warning() call within the except block to log each retry attempt, including the exception details and the calculated backoff delay duration when attempt < max_retries. Additionally, add a logger.warning() call immediately before the final return statement to log when all retries have been exhausted and the service enters CRITICAL status. This ensures operators have visibility into retry behavior and can diagnose why health checks are delayed or degraded.

Inline comments:
In `@shanaboo_solution.md`:
- Around line 1-26: The documentation shows usage examples with CLI flags
`--max-retries`, `--backoff-factor`, and `--circuit-threshold` on the usage
line, but the `parse_args()` function does not define these arguments. Since
`run_health_checks()` attempts to read `max_retries` and `backoff_factor` via
`getattr(args, ...)` at lines 200-201, the arguments must be added to the
argument parser in `parse_args()`. Add these three arguments to the argparse
ArgumentParser with appropriate types (integer for max-retries and
circuit-threshold, float for backoff-factor) and default values to match the
contract expected by `run_health_checks()`.
- Around line 37-88: The CircuitBreaker class is defined but never integrated
into the probe_with_retry() function, so the circuit breaker checks and state
tracking are completely missing. You need to wire the circuit breaker logic into
probe_with_retry() by first calling can_execute() on the appropriate circuit
breaker before attempting a probe (returning early if it returns False), and
then calling either record_success() or record_failure() on the circuit breaker
based on whether the probe attempt succeeded or failed. This will ensure the
circuit breaker actually opens to prevent repeated probes of downed services.
You can accomplish this by adding these calls within probe_with_retry() itself
or by wrapping calls to probe_with_retry() in run_health_checks() with the
necessary circuit breaker state management.
- Around line 187-201: The file ends with a syntax error on line 201 where the
backoff_factor getattr call is incomplete, missing the closing quote and
arguments. Complete the incomplete getattr call for backoff_factor with proper
closing quotes and default value, then finish implementing the run_health_checks
function by adding the missing circuit_threshold argument parsing, the complete
probe_with_retry function implementation, circuit breaker state management
functions (can_execute, record_success, record_failure), integration of
aggregate_results into the output, and logging of degraded service warnings.
Ensure all functions referenced in the function body are fully implemented and
the file ends with proper syntax.
- Around line 1-201: Update the parse_args() function to register the three new
CLI arguments --max-retries, --backoff-factor, and --circuit-threshold with
appropriate types and default values. Then modify the main() function to pass
the full args object to run_health_checks() instead of individual positional
arguments, matching the updated function signature. Integrate the
probe_with_retry() function with circuit breaker gating into the service check
loop within run_health_checks() by replacing direct calls to
check_http_service() and using get_circuit_breaker() to gate execution based on
CircuitBreaker.can_execute(). Complete the truncated diff at line 201 to show
all implementation details. Finally, create a separate test file with at least
five unit tests covering retry logic with exponential backoff, circuit breaker
state transitions, and the aggregate_results() function.

Critical signature mismatch and incomplete implementation: parse_args() not updated, probe_with_retry() unintegrated, no tests.
The PR has several critical gaps that would cause runtime failures if merged:
-
Breaking function signature change: The diff changes
run_health_checks()fromrun_health_checks(service, json_output)torun_health_checks(args: argparse.Namespace), butmain()still calls it asrun_health_checks(args.service, args.json)with positional arguments. This will break execution immediately. -
parse_args() not updated: The CLI argument parser still defines only
--service,--json,--watch,--interval,--output. The diff adds no code to register--max-retries,--backoff-factor, or--circuit-threshold. The lines at 200-201 that read these viagetattr(args, ...)will always use defaults since parse_args() will never populate them. -
New functions defined but never called:
CircuitBreaker,get_circuit_breaker(),probe_with_retry(), andaggregate_results()are added to the module but not integrated into the health check loop. The service checks still callcheck_http_service()directly without retry or circuit breaker logic. -
Incomplete diff: The submission ends abruptly at line 201 (mid-sentence), indicating the full change set is not included.
-
No unit tests: PR objectives require at least 5 unit tests for retry, backoff, and circuit breaker scenarios. None are provided.
Required fixes:
- Update
parse_args()to add the three new CLI arguments with proper types and defaults. - Change
main()to pass the fullargsobject torun_health_checks(), or revert the signature change and extract values from args before calling. - Integrate
probe_with_retry()with circuit breaker gating into the service check loop inrun_health_checks(). - Provide the complete diff (currently truncated).
- Include a test file with 5+ unit tests covering all new functionality.

In `@tools/health_check.py`:
- Around line 120-126: The condition on line 123 in the _get_circuit_state
function uses `if None:` which always evaluates to False, preventing proper
initialization of new circuit state entries. Replace `if None:` with `if state
is None:` to correctly check if the state variable is None (i.e., the key
doesn't exist in _circuit_state). This ensures that when a new key is accessed,
the state dictionary is properly initialized with default values before being
returned and used elsewhere.
- Around line 182-190: The check_tcp_port function is missing the try block that
should precede the except clauses, and there is a duplicate stray return
statement at the end. Add a try block after the function definition that
contains the actual TCP socket connection logic (creating a socket, setting
timeout, and connecting to the host and port), wrap it with the existing except
clauses that handle TimeoutError, ConnectionRefusedError, and general Exception
cases, and remove the duplicate return statement at line 190 that is currently
orphaned outside the function structure.
- Line 90: The statement `status = resp.status` at line 90 is incorrectly
indented at module scope, causing a Python parsing error. Either remove the
leading indentation to place this statement at the proper module level, or move
it inside the appropriate function or conditional block where it logically
belongs (likely within a function that handles the response object). Ensure the
indentation is consistent with the surrounding code structure.

that reduce clarity. Remove the duplicate entry for Redis connectivity (the
second occurrence of the ping test line in the numbered list), remove the second
occurrence of the sentence beginning with "Each check returns a status of OK,
WARNING, or CRITICAL, along with", and remove the duplicate "--watch" usage
example line. Each of these entries should appear only once in the docstring.
- Around line 28-31: The backoff delay calculation does not implement the
specified exponential backoff formula. Replace the current implementation that
uses `timeout` as the base delay with a configurable `base_delay` parameter, and
update the delay calculation at all occurrences (around lines 54-56 and 135-137)
to use the formula `delay = base_delay * (backoff_factor ^ attempt)`. Ensure
that base_delay is properly configured as a parameter rather than reusing the
timeout value.
- Around line 117-121: The check_tcp_port function currently measures only local
code execution time and returns success without actually attempting to connect
to the socket, making it unable to detect infrastructure outages. Fix this by
adding an actual socket connection attempt: create a socket, set the timeout
parameter on the connection attempt, and connect to the specified host and port.
Measure the latency from before the connection attempt to after it completes
successfully. Return appropriate error responses if the socket connection fails,
and only return OK status if the actual TCP connection to the host and port
succeeds.
- Around line 133-134: The check_certificate_expiry function signature is
incomplete with a dangling comma after the host parameter and missing closing
parenthesis. Complete the function signature by adding all required parameters
(including port and any others referenced in the function body such as ctx)
before the colon that precedes the function body. Ensure the function
declaration is syntactically complete with proper parameter list closure before
the with statement begins on the next line.

check_tcp_port currently reports success without probing the port.
Line 121 always returns OK after timing only local code execution; no socket connect is attempted, so infra outages become false positives.

check_certificate_expiry function signature is syntactically incomplete. Line 133 opens the function declaration but does not close it, leaving a dangling comma. Line 134 immediately begins the function body with a with statement, which is invalid Python syntax. The signature also references undefined variables (port on line 134 and ctx on line 135) that are never declared.
