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.

@JoelSpeed I updated the doc and gave claude more specific instructions, now we have:

● I'll run a comprehensive API review for PR #2547. Let me start by creating a todo list and then executing the review workflow.

● Let me start by fetching the API conventions documents to understand the requirements.

● Fetch(https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md)

● Fetch(https://github.com/openshift/enhancements/blob/master/dev-guide/api-conventions.md)
  ⎿  Received 309.9KB (200 OK)

● Now let me run the pre-flight checks and start the PR review process.

● Bash(CURRENT_BRANCH=$(git branch --show-current) && echo "📍 Current branch: $CURRENT_BRANCH" && PR_NUMBER=2547 && echo "🔍 PR review mode: Reviewing PR #$PR_NUMBER"…)

What did the updated claude pick up on this time? Did it pick up any specific violations?

[saschagrunert]

What did the updated claude pick up on this time? Did it pick up any specific violations?

I think this needs a bit more manual testing with real world examples. Let's wait for another API PR to come in and compare the new vs the old review behavior.

[openshift-ci]

@saschagrunert: all tests passed!

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository. I understand the commands that are listed here.

[yuqi-zhang]

I tried this branch vs master: #2510 (review)

It did explicitly call out the compliance, but had less suggestions compared to master for some reason, but maybe just inconsistent there.

[saschagrunert]

I gave it a final run over #2544, comparing main to this branch. The outcome was that the instructions from this branch found more documentation issues, for example:

  Required Changes

  1. Enum Type Documentation (9 issues)

  All enum types with +kubebuilder:validation:Enum markers must document their valid values in the type comment.

  Line 7-9: PacemakerDaemonStateType

  Current (problematic) code:
  // PacemakerDaemonStateType represents the state of the pacemaker daemon
  // +kubebuilder:validation:Enum=Running;KnownNotRunning
  type PacemakerDaemonStateType string

  Suggested change:
  -// PacemakerDaemonStateType represents the state of the pacemaker daemon
  +// PacemakerDaemonStateType represents the state of the pacemaker daemon.
  +// Valid values are:
  +// - "Running": the pacemaker daemon is in the 'running' state
  +// - "KnownNotRunning": the pacemaker daemon is not in the 'running' state (covers states like init, wait_for_ping, starting_daemons, shutting_down, shutdown_complete, etc.)
   // +kubebuilder:validation:Enum=Running;KnownNotRunning
   type PacemakerDaemonStateType string

  Explanation: The +kubebuilder:validation:Enum marker requires documentation of all valid enum values in the type comment.

  ---
  Line 20-22: QuorumStatusType

  Current (problematic) code:
  // QuorumStatusType represents the quorum status of a Pacemaker cluster
  // +kubebuilder:validation:Enum=Quorate;NoQuorum
  type QuorumStatusType string

  Suggested change:
  -// QuorumStatusType represents the quorum status of a Pacemaker cluster
  +// QuorumStatusType represents the quorum status of a Pacemaker cluster.
  +// Valid values are:
  +// - "Quorate": the cluster has quorum
  +// - "NoQuorum": the cluster does not have quorum
   // +kubebuilder:validation:Enum=Quorate;NoQuorum
   type QuorumStatusType string

  Explanation: The +kubebuilder:validation:Enum marker requires documentation of all valid enum values.

Using the instructions from main claude said everything is fine.
