I miss having commands for suspending, resuming and trigger an immediate reconcile using the cli.
Using kubectl directly to add crossplane specific annotations works but its annoying to remember the exact names and values and also there is no easy way to apply to the resource tree.
Notably they all come with support for --cascade and --watch to apply to the entire resource tree as well as follow reconciliation.
Note: I did not add tests for the commands and I placed them currently into the trace package. Thats obviously not ideal name wise and there is some code dup now. Probably package should be renamed. I will add test and refactor the package a bit as long as I know this feature would get merged?
The resource CLI adds suspend, resume, and reconcile commands. Trace support moves into the tree package, where the new commands use its resource selection, tree, watch, and output behavior.
Changes: Resource tree commands
Layer / File(s)
Summary
Tree trace foundation cmd/crossplane/trace/trace_test.go, cmd/crossplane/tree/trace.go, cmd/crossplane/tree/watch.go, cmd/crossplane/tree/trace_test.go, cmd/crossplane/tree/trace_integration_test.go
Trace support moves into the tree package as TraceCmd. Output handling moves to printResources, which handles list output, watch warnings for lists, and empty single-resource results. Tests cover resource parsing and output handling in the tree package.
The resource command registers suspend, resume, and reconcile. New help files describe resource selection, cascade and watch options, output formats, and examples.
Suspend and resume resource updates cmd/crossplane/tree/suspend.go, cmd/crossplane/tree/resume.go, cmd/crossplane/tree/helpers_test.go, cmd/crossplane/tree/suspend_test.go, cmd/crossplane/tree/resume_test.go
Suspend sets the paused annotation, and resume removes it. Both commands can update resource trees recursively, then watch a named resource or print results. Tests cover annotation updates and update failures.
Reconcile sets a reconcile-requested timestamp and removes the paused annotation. It can update a resource tree recursively, then watch a named resource or print results. Tests cover annotations, timestamps, and update failures.
crossplane/cli#482: Adds the trace integration test that this change moves into the tree package and updates to use TraceCmd.
crossplane/cli#497: Adds operation enrichment to trace trees and watch output, which the relocated trace implementation uses.
Merge Risk: Low · previous review f5f54
The new suspend, resume and reconcile commands can fail partway through a cascade if a controller updates a resource between the read and the write. Some resources may then be changed and others not. The impact is limited and rerunning the command recovers, but the error message should say so before merge.

The description matches the new suspend, resume, and reconcile commands and their cascade and watch options. Its note about missing tests and the trace package is outdated.
Full details: Breaking Changes
Explanation
No checked breaking change is introduced. In cmd/crossplane/resource/resource.go, the existing Trace command remains and keeps the same CLI fields and flags; the PR adds optional suspend, resume, and reconcile subcommands. The trace implementation and flags move to tree.TraceCmd without removing trace CLI behavior. No files under apis/** change, and no existing public field or flag is removed or renamed.
Full details: Feature Gate Requirement
Explanation
The new commands inherit the resource command’s beta maturity level; they are not marked experimental. They change reconciliation only when invoked, and the PR does not change apis/**. The check requires a feature flag for new experimental features.

The nil-map fix is good, but the current head still has two user-visible correctness issues called out in the first review: all three recursive applyAnnotation methods discard child errors, so --cascade can report success after failing to update a descendant; and named-resource runs without --watch return without printing anything. Please propagate/wrap recursive errors and print the updated named resource in non-watch mode, with focused tests for descendant failure and named output. The docs also still say a name is required while documenting all-resources invocations, and the resume/suspend cascade snippets invoke resource reconcile. This review was prepared with AI assistance; I independently inspected head 95ea3696 and take responsibility for the feedback.
Hi @raffis - thanks for the contribution and apologies for taking so long to take a look. These look like fairly simple, useful commands. As you say, some refactoring is necessary to move them into the right package; feel free to break out shared code from trace into a new internal package if it's helpful. I'm happy to review and merge when it's ready.

Please align the help text with Crossplane naming.
The help text uses lowercase "crossplane" for the product name. Other help strings in the CLI use "Crossplane". Consider using the capitalized form in all three strings.
The earlier "reconcilication" typo is fixed. Thank you.

Thank you for extracting printResources. One question about empty lists.
In list mode, printResources calls p.PrintList. The default and dot printers return an error for an empty list: "resource list is empty". When crossplane resource suspend|resume|reconcile mykind matches no resources, the user sees cannot print output: ...resource list is empty. The mutation commands also call applyAnnotation before this point, so the user sees an error after a successful no-op.
Was this error intended for the empty case? A clearer message would help, such as "no resources of kind X found in namespace Y". Returning early with a short notice when len(resourceList.Items) == 0 would also work. The JSON and YAML printers already print an empty list.
This is a suggestion only. The behavior may be intentional and may match the previous trace behavior.

Consider extracting the shared Run flow for suspend, resume and reconcile.
Thank you for adding these commands. The PR description already notes the duplication, so this is a pointer for the follow-up refactor. The Run bodies in suspend.go, resume.go and reconcile.go are identical except for the applyAnnotation receiver. Each body covers printer setup, kube client setup, mapping, namespace resolution, get or list, cascade tree loading, apply, then watch or print.
Could you share one helper, with the per-command annotation mutation passed as a function? For example, add func (c *TraceCmd) runAnnotate(k *kong.Context, logger logging.Logger, cascade bool, apply func(ctx context.Context, cl client.Client, rs []*resource.Resource) error) error. A bug fix in this flow then needs only one change.
The recursive tree walk is also duplicated three times. One generic mutateTree(ctx, cl, resources, mutate func(*unstructured.Unstructured)) would cover all three commands.
