claude: take latest OpenShift and Kubernetes API conventions into account

[saschagrunert]

It would be good if claude uses the latest conventions to do the review. On top of that it should check for naming convention issues during the documentation checks.

  API Review Report for PR #2547

  Summary

  PR #2547 adds a new field HTTPKeepAliveTimeout to the IngressControllerTuningOptions struct in operator/v1/types_ingress.go. The linting checks passed successfully with 0 issues.

  Documentation Analysis

  I have reviewed the new field against the OpenShift and Kubernetes API conventions. The field documentation is well-written and comprehensive. Here's what was verified:

  ✅ Field Documentation Quality

  The HTTPKeepAliveTimeout field (lines 1887-1901) includes:

  1. Clear Purpose: Explains what the field does - "defines the maximum allowed time to wait for a new HTTP request to appear"
  2. Format Specification: Clearly documents the expected duration format with examples ("300ms", "1.5h", "2h45m")
  3. Valid Time Units: Lists all valid time units ("ns", "us", "µs", "μs", "ms", "s", "m", "h")
  4. Optional Field Behavior: Explicitly states what happens when omitted - "the user has no opinion and the platform is left to choose a reasonable default"
  5. Default Value: Documents the current default (300s) and notes it's subject to change
  6. Kubebuilder Markers: All validation markers are properly documented:
    - +optional - behavior when omitted is explained
    - +kubebuilder:validation:Pattern - pattern is documented in the comment via format/examples
    - +kubebuilder:validation:Type:=string - implicitly documented as "duration string"

  ✅ Validation Marker Documentation

  All kubebuilder markers have corresponding documentation:
  - Pattern validation: The regex pattern ^(0|([0-9]+(\.[0-9]+)?(ns|us|µs|μs|ms|s|m|h))+)$ is documented through the description of valid formats and examples
  - Optional nature: Clearly explained with default behavior
  - Type constraint: Documented as "unsigned duration string"

  ✅ Consistency with Existing Fields

  The documentation style and format is consistent with other similar timeout fields in the same struct:
  - connectTimeout (lines 1871-1885)
  - healthCheckInterval (lines 1915-1939)

  All follow the same pattern of explaining format, valid units, and default behavior.

  Review Outcome

  ✅ PASS - The API changes meet all documentation requirements:

  1. ✅ Linting checks passed (0 issues)
  2. ✅ Field is properly documented with clear purpose
  3. ✅ Optional field behavior when omitted is explained
  4. ✅ All validation markers are documented in comments
  5. ✅ Default values and format constraints are specified
  6. ✅ Documentation style is consistent with existing fields
  7. ✅ Generated files (deepcopy, CRD manifests, swagger) are up-to-date

  Recommendations

  No issues found. The implementation follows OpenShift API conventions and best practices. The documentation is clear, comprehensive, and consistent with the rest of the codebase.

● Bash(git checkout claude && echo "✅ Switched back to branch: $(git branch --show-current)")
  ⎿  Your branch is up to date with 'origin/claude'.
     ✅ Switched back to branch: claude
     Switched to branch 'claude'

● API Review Complete ✅

  I've successfully completed a comprehensive API review for PR #2547 which adds the HTTPKeepAliveTimeout field to the IngressController API.

  Review Results

  Status: APPROVED - All checks passed

  What Was Reviewed

  1. Linting: make lint ran successfully with 0 issues
  2. Field Documentation: The new HTTPKeepAliveTimeout field is thoroughly documented
  3. Validation Markers: All kubebuilder markers are properly documented in comments
  4. API Conventions: Follows both OpenShift and Kubernetes API conventions

  Key Findings

  The PR introduces a new optional field HTTPKeepAliveTimeout to IngressControllerTuningOptions with excellent documentation that:

  - ✅ Clearly explains the field's purpose and behavior
  - ✅ Documents the format requirements with examples
  - ✅ Specifies valid time units
  - ✅ Explains behavior when the field is omitted (defaults to 300s)
  - ✅ Documents all validation constraints (pattern, type)
  - ✅ Is consistent with similar fields in the codebase
  - ✅ All generated code (deepcopy, CRD manifests, swagger docs) is up-to-date

  No Issues Found

  The implementation meets all OpenShift API requirements and best practices. The documentation is clear, comprehensive, and provides all necessary information for API users.
