observe-crossplane from confighub/cub-scout is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when the user wants to observe CROSSPLANE-managed resources specifically — the controller-specific observer skill for Crossplane. Natural phrasing: "is this a Crossplane managed resource?", "which XR / Claim / Composition produced this?", "show me Crossplane composed children", "what does the `apiextensions.crossplane.io/composed-<hash>` manager mean?", "trace this resource back to the Claim", "is this from `*.crossplane.io` or `*.upbound.io`?", "show me ProviderConfig secrets". Load…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# observe-crossplane
The controller-specific observer skill for **Crossplane**. cub-scout's coverage here is comprehensive — XRs, Claims, MRDs, composite/composed, the reference resolver, and the `crossplane-system` control-plane subset. This skill is the field guide.
Verified against `pkg/agent/ownership.go` (`detectCrossplaneOwnership`, `detectCrossplaneSystemOwnership`) and `pkg/agent/manager_strings.go` Crossplane constants.
Marked **experimental** in `CLAUDE.md` § "Ownership Detection" — the breadth of provider-specific writers Crossplane gets composed through means edge cases keep appearing.
## When to use
- "Is this a Crossplane managed resource?"
- "Which Claim / XR / Composition produced this?"
- "Show me the composed children of this composite resource"
- "What does the `apiextensions.crossplane.io/composed-<hash>` manager string mean?"
- "Trace this resource back to the Claim"
- "Is this in `*.crossplane.io` or `*.upbound.io`?"
- "Show me ProviderConfig secrets"
## Do not load for
- Generic ownership ("who owns this resource?") — [`scout-observe`](../scout-observe/SKILL.md)
- Helm / Argo / Flux specifically — their respective `observe-*` skills

How to install
mdr add confighub/cub-scout/observe-crossplane@sha256:ca324d31924fa2ecThe line at the top of this page pins the label git:20260926.4c4b67c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
