Experimental

Build and manage a kind cluster for Workload-Aware Scheduling (WAS) e2e tests. Use when the user wants to set up, run tests against, or tear down a WAS test cluster built from Kubernetes main.

Trace workload lineage to pods. Use when a user wants to trace lineage across any tier such as workload to pods, pod to workload, or job to workload. The user may provide a resource at any level (Workload, Job, Pod, JobSet, etc.) and this skill produces the full tree from Workload down to Pods.

Review a diff for comment hygiene — over-commenting, what-not-why narration, inaccurate comments, and missing TODOs on compatibility shims.

Review a diff for security issues exploitable by a tenant, neighbouring controller, or malicious workload spec — input validation, injection, DoS, nil-safety, authz, info disclosure, supply chain, webhook safety.

Evaluate the quality of a git diff between two commits by delegating per-skill analysis (Code Style, Buggy Behavior, Comments, Architectural Decisions, Security) to subagents, then aggregating their findings and recommendations into a scored report.

Write or review Kueue PR release notes. Use when a user asks to draft, refine, validate, or combine release notes for a Kueue pull request, especially when deciding whether the note should be framed as a bugfix, feature, observability improvement, or breaking change.

Identify what preempted a workload. Use when a user asks why their workload was evicted or preempted, or wants to identify what preempted it. Investigates Kubernetes events, workload status conditions, and controller logs to trace preemption.

Review a diff for naming precision, convention drift, reinvented helpers, log-verbosity mistakes, misaligned test names, and typos.

Debug Kueue CI flakes. Use when a user asks to debug a flake, investigate a test failure, a test timeout, or a CI flake. Analyzes Prow build logs, kube-scheduler logs, kubelet logs, and test code to identify root causes.

Review a diff for behavioral defects — logic errors, broken edge cases, feature-gate bugs, and deletions that break backwards compatibility during rolling upgrades.

Review that local variables with unnecessarily wide scope are extracted into helper functions.

Review concurrent Go code for races, preferring fixes at the mutation site over adding snapshot fields.

Review that new feature tests are split into their own file rather than added to an already large test file.

Review that new CRD fields have complete godoc comments with enum value descriptions.

Flag injection vectors from user-supplied strings — exec, SSRF, fmt.Sprintf-built selectors/URLs, template rendering, query concatenation (CWE-78, CWE-94, CWE-918).

Create (or reuse) the manager + worker kind clusters for Kueue MultiKueue e2e development. Use when a user asks to spin up MultiKueue e2e clusters, get a local multi-cluster environment ready, or debug/iterate against a MultiKueue e2e suite (baseline, extended, sequential, DRA).

Create (or reuse) a single kind cluster for Kueue e2e development. Use when a user asks to spin up an e2e cluster, get a local kind environment ready for e2e tests, or debug/iterate against a single-cluster e2e suite (baseline, extended, sequential, TAS, cert-manager, DRA).

Review a diff for small-scale structural problems — unjustified complexity, duplicated logic, scope creep, or misplaced code.

Flag identifiers whose name does not describe exactly what they contain — drift from package patterns, contradictory contents, misnamed feature gates, asymmetric mirror fields.

Flag missing resource bounds / DoS resistance — uncapped loops or allocations, missing timeouts, reconciler-wedging input, unbounded metric cardinality (CWE-400, CWE-770).

Flag AuthN/AuthZ relaxation — webhook token skipping, failurePolicy Ignore, missing SubjectAccessReview, wildcard RBAC, privileged pod specs (CWE-269, CWE-287, CWE-306, CWE-862, CWE-863).

Flag information-disclosure patterns — full-object logging, request echoing, credentials in status/annotations, kubeconfig logging, secret-bearing status (CWE-200, CWE-522, CWE-532, CWE-552).
