Conciseness

Mostly lean tables and copy-paste commands that assume Claude's competence (no explaining Docker or Compose basics). Minor redundancy: 'When to Activate' restates the frontmatter description and 'How It Works' overlaps 'Core Concepts', keeping it below the 'every token earns its place' anchor.

Actionability

Fully executable throughout: concrete `uc` commands with flags, complete compose examples with `x-ports`/`x-caddy`/`x-machines`, and a copy-paste-ready external-device recipe (`uc service run --name device-bmc --caddyfile ~/device.caddyfile registry.k8s.io/pause:3.9`). Specific examples cover the common cases, matching the top anchor.

Workflow Clarity

The external-device routing workflow is a clear numbered 3-step sequence with an explicit verify checkpoint ('uc caddy config — device block should appear'). Not 5 because other workflows (deploy, scale, `uc machine rm`, `uc deploy --recreate`) lack validation or verification steps despite being semi-destructive; well above 3 since the flagship multi-step process does have an explicit checkpoint.

Progressive Disclosure

Well-organized headers make the single file navigable, but with no bundle files at all, ~345 lines — including a full CLI quick reference and a compose-extension catalog — are inlined when the bulk reference material could live in a separate one-level-deep file. Matches anchor 3 ('structure present, content that should be separate is inline'); not 2 because sections are clear and navigable, not 4 because no references are used to split content.

Specificity

Lists multiple specific concrete actions — 'deploying services, configuring Caddy ingress, adding static proxy routes for non-cluster devices, publishing ports, scaling, inspecting logs, or managing machines and volumes' — with comprehensive coverage, matching the top anchor. Not 4 because there are no notable coverage gaps among the skill's documented capabilities.

Completeness

Explicitly answers both what (the enumerated actions with the `uc` CLI) and when ('Use when managing an Uncloud cluster') with concrete trigger phrases, mirroring the top anchor's pattern. Not 4 because the 'when' is fully explicit rather than merely present.

Trigger Term Quality

Good keyword coverage of natural user phrasing ('deploying services', 'publishing ports', 'scaling', 'inspecting logs', 'Caddy ingress'), but a few natural terms are missing (e.g., DNS, compose files, machine updates). Fits anchor 4 ('good coverage, a few natural terms missing') better than 5, which expects synonyms and fuller variations.

Distinctiveness Conflict Risk

'Uncloud cluster' and the `uc` CLI name a clear niche with distinct triggers; minimal conflict risk with any other skill. Clearly matches the top anchor rather than 4, which allows minor overlap with closely related skills.
