Conciseness

The seven templates and command sections are lean, but the body pads with content Claude does not need: a vacuous "Do not use this skill when" section ("The task is unrelated to linkerd patterns"), generic filler Instructions ("Clarify goals, constraints, and required inputs. Apply relevant best practices"), an ASCII architecture diagram of concepts Claude already knows, and a repeated marketing tagline. Version-pinned URLs ("linkerd.io/2.14/") are time-sensitive and not quarantined in a deprecated section, which the guidelines say should penalize conciseness. This fits anchor 3 ("mostly efficient but includes some unnecessary explanation or could be tightened") — not 4 because the filler sections and version pins are more than minor trimmings.

Actionability

Seven templates provide copy-paste-ready, complete bash and YAML: install sequence with `linkerd check` validation, namespace/deployment injection annotations, a full ServiceProfile with routes/responseClasses/retryBudget, TrafficSplit with SMI weights, Server/ServerAuthorization policies, HTTPRoute rules, and multicluster link/export/check commands, plus concrete viz/tap debugging commands. This matches anchor 5 ("fully executable; copy-paste ready code or commands; specific examples cover the common cases") rather than 4, which allows for minor gaps the examples here don't have.

Workflow Clarity

The install template is properly sequenced with validation checkpoints (`linkerd check --pre` before, `linkerd check` after, `linkerd multicluster check`), and the Best Practices Don'ts mandate re-running checks after changes. It is not 5 because there is no error-recovery loop (what to do when a check fails) and the top-level "Instructions" section gives no real sequencing across the pattern catalog; it is not 3 because concrete checkpoints are explicitly present, not merely implied.

Progressive Disclosure

Section headers and a Key Resources table give the ~300-line body reasonable organization, but the single external reference — "open `resources/implementation-playbook.md`" — is broken: no references/, resources/, scripts/, or assets/ directory exists in the bundle, so the path resolves to nothing, and it is buried in an Instructions bullet rather than clearly signaled. This matches anchor 3 ("some structure but could be better organized; references present but not clearly signaled") — not 2 because the inline templates are appropriately presented as a pattern catalog with clear headers rather than a monolithic dump.

Specificity

The description names the domain ("Linkerd service mesh", "Kubernetes") but lists zero concrete actions — it is a marketing tagline ("lightweight, security-first") rather than a statement of what the skill does (install, configure mTLS, traffic splits, etc.). It fits anchor 2 ("names the domain but actions are minimal or generic") better than anchor 1 because the domain itself is concrete and specific, and better than anchor 3 because no capability is enumerated at all.

Completeness

It has a recognizable "what" (production patterns for Linkerd service mesh) but no "when" clause whatsoever — no "Use when..." or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because the "when" is entirely absent rather than merely implicit, and not 2 because the "what" is domain-clear even if actionless.

Trigger Term Quality

"Linkerd", "service mesh", and "Kubernetes" are natural terms users would say, but the description omits the common task-level phrases users actually utter — mTLS, canary, traffic split, retries, multi-cluster — which the body's own "Use this skill when" section covers. This matches anchor 3 ("some relevant keywords but missing common variations or synonyms") and falls short of anchor 4's broader keyword coverage.

Distinctiveness Conflict Risk

"Linkerd" is a specific named tool, giving a clear niche with minimal conflict risk against unrelated skills. It is not 5 because the triggerless description could overlap with closely related service-mesh skills (e.g., an Istio skill) since no differentiating task verbs are stated, and the generic "service mesh for Kubernetes" tail slightly broadens it.
