Walkthrough

Two new top-level documentation files were added: AGENTS.md and CLAUDE.md, introducing guidance on the Cluster Version Operator (CVO) including architecture, build/test commands, release payloads, update/manifest flows, debugging, and operational notes.

Changes

Cohort / File(s) Change Summary
New documentation files
AGENTS.md, CLAUDE.md
Added two root-level documentation files describing CVO concepts: architecture (main loop, sync worker, payload management, resource libraries, preconditions), entry points, release payload structure and image naming, update flow and manifest application order, build/test commands, debugging procedures, common file locations, commit message conventions, and operational notes (leader election, signature verification, capability filtering).

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

  • Verify technical accuracy of architecture, update/task-graph descriptions, and manifest application order in AGENTS.md.
  • Check build/test command examples, file paths, and release image naming patterns for correctness.
  • Compare AGENTS.md and CLAUDE.md for overlap, duplicated content, or inconsistent terminology and reconcile as needed.
✨ Finishing touches
🧪 Generate unit tests (beta)
  • Create PR with unit tests
  • Post copyable unit tests in a comment

1-1: Resolve critical mismatch: CLAUDE.md appears to contain only a reference to AGENTS.md instead of the comprehensive CVO documentation described in the PR.

The file content shows only "AGENTS.md" on line 1, but the PR description indicates CLAUDE.md should contain comprehensive guidelines covering CVO architecture, build/test procedures, development workflows, and more. Either the file content is incomplete/incorrect, or the files may be reversed or mislabeled.

Please clarify:

  • Should CLAUDE.md contain the full documentation currently shown as AGENTS.md content?
  • Are the filenames and content correctly assigned?
  • If CLAUDE.md should only reference AGENTS.md, this should be documented more explicitly with proper context.

129-142: Document security considerations for the cluster patching example.

Lines 129–142 provide practical guidance for testing changes locally, including direct JSON patch operations on the CVO deployment. While the comment emphasizes "disposable test clusters only!", consider adding a brief warning about the risks of manually patching deployments in production (e.g., circumventing GitOps workflows, losing changes on operator reconciliation).

Consider adding a note like:

 # Inject into running cluster (disposable test clusters only!)
+# WARNING: Manual patches are temporary and will be overwritten by the cluster operator.
+# Use only for testing; for persistent changes, modify the release payload or use proper GitOps workflows.
 pullspec=${REPO}/ocp-release:latest

This reinforces best practices and prevents accidental misuse of this pattern.

CLAUDE.md (1)

1-1: Clarify the purpose of CLAUDE.md.

This file contains only a reference to "AGENTS.md" without explanation. If this is meant to be a redirect or entry point to the documentation, make that explicit. If it serves no purpose, consider removing it in favor of relying on AGENTS.md directly.

Can you explain the intended purpose of this file and whether it should contain additional guidance or if it can be removed?

AGENTS.md (2)

48-126: Verify heading hierarchy is intentional.

The architecture sections now use level 4 headings (####) nested under "Core Components" (level 3, line 48). While this creates a valid hierarchy, the previous review suggested level 3 headings (###).

Confirm whether the deeper nesting (#### instead of ###) is intentional, or if sections should be promoted to level 3 for better document structure and accessibility. This affects both the "Core Components" subsections (lines 50–91) and the "Key Patterns" subsections (lines 105–126).

Can you confirm whether the level 4 heading choice is intentional? If not, the document may benefit from promotion to level 3 (###) for better visual hierarchy and outline navigation.


160-165: Verify referenced documentation file paths exist.

Lines 164–165 reference two documentation files in the docs/dev/ directory:

  • feed-cvo-custom-graphs.md
  • run-cvo-locally.md

Confirm these files exist at the specified paths to ensure the documentation references are valid and not broken links for readers following this guide.

77-82: Consider mentioning auto-generated file in Resource Libraries section.

The Resource Libraries section describes the contents of lib/, but some files in this directory are auto-generated via hack/generate-lib-resources.py. This context would be helpful for developers working with or modifying these libraries.

You may optionally add a note like:

 #### Resource Libraries (lib/)
 - `resourcebuilder/`: Builds Kubernetes resources from manifests
 - `resourceapply/`: Applies resources with proper merge semantics for different API types
 - `resourcemerge/`: Merges resource specifications
 - `resourceread/`: Reads and validates manifests
 - `capability/`: Manages cluster capability filtering
+
+Note: Some resource library files are auto-generated via `hack/generate-lib-resources.py`.

120-128: Clarify signature validation timing in the Update Flow.

The current description suggests signature validation happens after retrieval, but signature validation actually occurs before retrieving the payload image (as noted in prior review feedback). This is an important detail because signature verification prevents launching an untrusted image. Additionally, there is no way to disable verification; force: true skips validation attempt failures but doesn't disable verification itself.

Consider rewording line 124 to reflect this sequence:

 #### Update Flow
 1. CVO fetches available updates from configured upstream (OSUS)
 2. Updates stored in `status.availableUpdates` and `status.conditionalUpdates` of `ClusterVersion` resource
 3. User/admin sets `spec.desiredUpdate` to trigger upgrade
-4. Validates payload signatures
-5. CVO retrieves new release payload image
+4. Validates payload signatures (occurs before retrieval to ensure only trusted images are launched)
+5. CVO retrieves new release payload image

1-189: Documentation structure and accuracy look good overall.

The file is well-organized, covers essential CVO concepts, and provides practical guidance for AI assistants working with the codebase. Markdown formatting complies with linting standards, and the content accurately reflects CVO's architecture and workflows. The coverage of entry points, update flows, and debugging guidance is comprehensive.

Thanks! Looks good to me for initial content, and we can continue to refine this and the human-facing doc locations further in the future.
