Feature Request: Diff visibility for PreSync hook resources

[imuneeeb]

This request follows up on a previously closed issue where it was clarified that the current behavior is expected:

• Reference: Question: Are pre-sync resources intentionally excluded from diffs? #479

As mentioned there, kubechecks only generates diffs for existing, long-lived resources, and ArgoCD hooks do not appear in diff previews.

Problem / Limitation

In our setup, PreSync hooks are used for critical deployment logic, including:

• Backend database migration jobs
• Frontend asset build jobs
• ExternalSecret resources to fetch secrets before application sync

Any change in these resources can have a direct production impact. However, since diffs for hook resources are not shown, these changes are currently invisible during reviews.

Feature Request

Please consider adding an optional configuration to include diffs for hook resources (at least PreSync) based on their manifests, even if they are not continuously running resources.

This would significantly improve the visibility.

@imuneeeb looks like I was wrong in the previous issue

Can you set env var
KUBECHECKS_ENABLE_HOOKS_RENDER to true.

And try again?

@Greyeye
I tested with KUBECHECKS_ENABLE_HOOKS_RENDER=true, and also confirmed that the default value is already true.
In both cases, PreSync hook resources still do not appear in the diff output.
