How Kopiur writes and maintains user-facing docs — the MkDocs Material site under docs/ and the example manifests under deploy/examples/. Use when adding or editing any doc page, writing or changing an example manifest, or whenever you change operator behavior that affects how someone deploys, uses, or configures Kopiur (CRD fields, defaults, Helm values, RBAC, reconciler UX, kopia/mover invocation). Encodes the painfully-clear-for-three-audiences rule, the examples-live-in-deploy/examples-and-are-snippet-included convention, the simple→complex example ladder, and the docs-change-with-the-code discipline.
How Kopiur does strongly-typed, actionable error handling and end-to-end testing. Use when adding or changing any error type, error path, or fallible operation (kopia calls, kube IO, OTLP/telemetry init, validators, the mover), or when writing/extending tests — especially e2e scenarios in crates/e2e. Encodes the thiserror exhaustive-enum + classification pattern, the what/why/fix message rule, degrade-not-crash for non-critical subsystems, and the crates/e2e harness conventions (feature = "e2e", mise //crates/e2e:test, World::ensure(Need) provisioning, wait_phase/wait_until, assert real operator output, never a real cluster).
Design norms and locked decisions for the Kopiur Kopia-native Kubernetes backup operator (Rust/kube-rs). Use when adding or modifying CRD types, reconcilers, the admission webhook, the kopia client/mover, validators, or codegen in this repo — anything under crates/ or deploy/. Encodes the type-safety thesis, the externally-tagged-enum rule, k8s-openapi Eq constraints, the shared-validator pattern, retention/deletion semantics, and the build/test discipline. The code is the source of truth for current behavior; this skill summarizes the norms.
