Since we already have it README.md and .coderabbit.yaml, I only added AGENTS.md and CONTRIBUTING.md. I also added two new points that I think is relevant for AI workflow, which is verification and code conventions. These new points are relevant because we can ""force"" AI to follow the way that we write the code in this repo.

📝 Walkthrough

Walkthrough

The pull request adds repository-specific AI guidance in AGENTS.md, includes it from CLAUDE.md, and adds contribution procedures in CONTRIBUTING.md. The documentation covers architecture, development commands, coding conventions, testing, review policies, and repository practices.

Changes

Repository guidance and contribution workflow

Layer / File(s) Summary
Repository context and AI guidance
AGENTS.md, CLAUDE.md
Documents repository structure, operator architecture, reconciliation, configuration, feature gates, webhooks, pitfalls, and human-review triggers. CLAUDE.md references AGENTS.md.
Development and verification practices
AGENTS.md
Documents build, test, generation, vendoring, formatting, coding, testing, logging, error handling, paired changes, and commit conventions.
Contribution and review workflow
CONTRIBUTING.md
Adds setup, review, testing, generated-file, command, style, and pre-submit procedures.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to a8f68

This change only adds contributor and agent guidance, with no runtime product impact. A few instructions could mislead contributors or automation about verification commands, code generation, logging, and import conventions, so the PR is mergeable with explicit owner follow-up to align the documentation.

- Line 212: Update the Go testing guidance in AGENTS.md to state that test files

package, enabling access to unexported identifiers.

In `@CONTRIBUTING.md`:
- Line 197: Update the import-ordering guidance in CONTRIBUTING.md so it defines
two groups: standard-library imports first, followed by external and
project-internal imports together. Align the wording with the convention used by
AGENTS.md and pkg/operator/status.go.
- Line 196: Align the logging guidance in CONTRIBUTING.md and AGENTS.md on one
convention, resolving the conflict between structured klog key-value messages
and printf-style formatting. Match the chosen convention to the existing source
usage, including pkg/operator/status.go, or explicitly document the migration
scope if changing conventions.
- Around line 147-150: Update the documented /verified command examples in
CONTRIBUTING.md: replace “/verified deferred to QE” with “/verified later
`@github_username`”, and change the remaining verification examples to use
“/verified by <test name>, `@github_username`” or “/verified bypass”.

Restrict generation guidance to API types.

make generate regenerates deepcopy and CRDs, runs goimports, and verifies the diff. A change to a general Go interface does not require those generated artifacts. Replace “API types or interfaces” with “API types in pkg/apis/” to avoid unnecessary generation work.

I think I'll do even better, maybe use https://github.com/kubernetes-sigs/cluster-autoscaler instead of this one. Since it will be migrated in the future, I think it is worth it to reference the new one

I have a few small suggestions. Otherwise, looks good to me. I'll defer to @linkvt to give the final /lgtm once he is happy with it since he did the initial review. Thanks!

- The operator's job: translate the `ClusterAutoscaler` CR spec into command-line arguments and create/update a Deployment that runs the upstream autoscaler image.
- The autoscaler image is injected via the `CLUSTER_AUTOSCALER_IMAGE` env var (set by CVO from `install/image-references`).
- CR spec fields map to `--flag=value` arguments in `pkg/controller/clusterautoscaler/clusterautoscaler.go` (see the `AutoscalerArgs()` function).
- When working on this repo, you rarely need to touch upstream autoscaler code. Changes to autoscaler behavior are done via the CR spec fields here.

Do you think we could do without this table? I think the above reference is probably enough since an agent or human reading this can read the comments in the file which in the variable declaration section are quite extensive. My concern is that it would be a pain to keep this table in sync as options are added, removed or changed.

I agree, I'll keep the reference to the file only. Way easier to keep updated, thanks for the comment
