cub-apply

Apply (deploy) a ConfigHub Unit or group of Units to their Target via cub unit apply, respecting ApplyGates. Use for "apply this", "deploy this to staging", "push the change to the cluster", "roll out the fix", "apply everything unapplied", "apply the ChangeSet", "dry-run what would change". Not for rollback (use rollback-revision).

Quality

Content

92%

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

A strong, actionable operational runbook with clear sequencing and validation checkpoints. Its only real weakness is progressive disclosure: the body cites several reference files that are not present in the bundle.

Suggestions

Create the referenced bundle files (references/cub-cli.md, references/filters-and-queries.md, references/changesets.md) so the progressive-disclosure links resolve, or remove the dangling references.

Consider moving the ChangeSet lifecycle detail and filter-recipe lists fully into those reference files to keep SKILL.md as a tighter overview.

Verify the external docs URL (https://docs.confighub.com/markdown/guide/unit-sets.md) and companion-skill names resolve, since the references are the skill's main disclosure surface.

DimensionReasoningScore

Conciseness

Lean operational runbook with no concept-teaching padding; sections (preflight, loop, stop conditions) each earn their place, with only minimal operationally-relevant context setting.

3 / 3

Actionability

Fully executable cub commands throughout (apply --dry-run, --wait --timeout, --revision forms, cancel, tag) with specific flags and copy-paste-ready examples.

3 / 3

Workflow Clarity

Clear 7-step sequenced loop with explicit validation checkpoints (preflight gates, dry-run-first, blast-radius confirmation) and a feedback loop for timeouts (collect cub unit-event rather than blind retry).

3 / 3

Progressive Disclosure

References are clearly signaled and one-level-deep in intent (references/cub-cli.md, filters-and-queries.md, changesets.md), but the references/ directory does not exist on disk, so the promised disclosure layer is missing.

Description

100%

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

A highly specific, well-triggered description that answers what, when, and when-not with natural user phrasings and a clear boundary against the rollback skill. It is concise yet complete.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Apply (deploy) a ConfigHub Unit or group of Units to their Target via cub unit apply, respecting ApplyGates') naming the verb, objects, target, tool, and gates, plus an explicit exclusion.

3 / 3

Completeness

Clearly answers both what (apply/deploy Units to Target via cub unit apply respecting ApplyGates) and when via an explicit 'Use for' trigger list plus a 'Not for rollback' boundary.

3 / 3

Trigger Term Quality

Excellent natural-term coverage users would actually say: "apply this", "deploy this to staging", "push the change to the cluster", "roll out the fix", "apply everything unapplied", "apply the ChangeSet", "dry-run what would change".

3 / 3

Distinctiveness Conflict Risk

Distinctive niche with a named tool (cub unit apply) and an explicit conflict-avoidance boundary ('Not for rollback (use rollback-revision)'), unlikely to trigger for the wrong skill.
