container

Apple's native `container` CLI for running Linux containers as lightweight per-container VMs on macOS 26 Apple Silicon. Load when creating, configuring, managing, backing up, sharing, or deleting containers, images, volumes, or networks with `container`; when `container` or `container system start` fails; or when choosing between `container` and Docker/Podman/Colima on a Mac.

Quality

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is an extremely lean, well-executed delegation stub: it gives one unambiguous, concrete instruction with no wasted tokens. Its only structural weakness is that the delegated target is an absolute path outside the bundle with no in-bundle reference or fallback guidance, leaving the skill's actual content unverifiable from the bundle itself.

Suggestions

Reference the shared skill via a bundle-relative path (e.g., a file under references/) or ship the target within the bundle so the delegated content is present and verifiable where the skill is installed.

Add a one-line fallback for when the external path is absent (e.g., where to find or regenerate the shared skill), so the single instruction remains actionable in environments without ~/.agents/skills/container/SKILL.md.

DimensionReasoningScore

Conciseness

The body is two lines with zero padding: a generation comment and "Load and follow the shared skill at `~/.agents/skills/container/SKILL.md`." Every token earns its place and nothing explains what Claude already knows.

5 / 5

Actionability

The single written instruction is concrete and executable (exact path, exact action), but the body itself contains no container-task guidance — all actionable content lives behind an external file not shipped in this bundle. Not 5 because no commands or examples cover the domain's common cases; not 3 because the written step is fully specific rather than pseudocode or vague direction.

4 / 5

Workflow Clarity

This is a single-purpose skill whose one action — load and follow the referenced shared skill — is unambiguous; the simple-skill exception applies and no destructive or batch operations are involved.

5 / 5

Progressive Disclosure

The external reference is one level deep and clearly signaled ("Load and follow the shared skill at..."), but it points to an absolute home-directory path outside the skill bundle rather than an in-bundle file, and SKILL.md contains no overview content of its own. Not 5 because navigation depends on an environment-specific external path; not 3 because the reference is explicit and shallow, not buried or nested.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is exemplary: it states a precise capability, enumerates the full set of manageable objects and actions, and provides an explicit, multi-scenario load trigger including failure and comparison cases. Third-person voice is maintained and every phrase is a natural user term.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "creating, configuring, managing, backing up, sharing, or deleting containers, images, volumes, or networks" — plus a precise capability statement ("running Linux containers as lightweight per-container VMs on macOS 26 Apple Silicon"), giving comprehensive coverage of the CLI's object model.

5 / 5

Completeness

Explicitly answers what ("Apple's native `container` CLI for running Linux containers as lightweight per-container VMs") and when via a concrete "Load when..." clause covering task triggers, failure triggers, and tool-selection triggers.

5 / 5

Trigger Term Quality

Natural terms span containers, images, volumes, networks, Docker/Podman/Colima, Mac, and the failure phrase "container system start fails" — covering synonyms, competing tool names, and troubleshooting phrasings a user would actually say.

5 / 5

Distinctiveness Conflict Risk

Names the specific CLI, platform (macOS 26 Apple Silicon), and explicitly contrasts with Docker/Podman/Colima, establishing a clear niche with minimal risk of triggering the wrong container skill.
