Conciseness

Commands are exact and Concepts teaches genuinely novel domain facts (footprint vs. source, colocated/separate repos) Claude cannot already know, but the "don't stop after one command" message is repeated three times (the STOP blockquote, "This is a loop. Do not stop after the first step.", and "Concretely: do not stop after `repo new`."). Not 5 because that repetition is trimmable; not 3 because there is no padding explaining things Claude already knows.

Actionability

Every command is copy-paste ready with exact JSON payloads (`spektacular repo new --data '{"location":"<folder>"}'`, `repo goto --data '{"step":"<current_step>"}'`, the direct `repo add --data '{...}'` form), and the common cases are all covered: guided add, pre-supplied location, interrupted-add resume, fresh start with `--force`, scripting form, footprint repair, and manual removal. Fully executable guidance with no gaps.

Workflow Clarity

The add workflow is a clearly sequenced loop (instruction → step → goto) with explicit validation gates up front (`spektacular version check`, gating on `status: "match"`), feedback loops for error recovery (resume-report `kind` check, `repo_footprint_missing` → repair paths, `--status error` on failed trace spans), and user-confirmation checkpoints before destructive edits ("Confirm with the user before editing their config"). Not 4 because checkpoints and recovery paths are explicit, not merely present.

Progressive Disclosure

The single-file body is well-sectioned (When to invoke / Concepts / Adding / Inspecting / Materialization / Repair / Removal) with no nested or broken references — no bundle files exist to reference. At ~140 lines covering the whole repo surface, content like Materialization and staleness or the Concepts section could arguably live in a separate reference file, a minor organization gap. Not 5 because content is not split at all and the 50-line simple-skill exception doesn't apply; not 3 because structure and navigation are genuinely good.

Specificity

"Add a repo to the current Spektacular project through a guided conversation, inspect the registry, and repair a repo's footprint" lists three specific concrete actions with clear mechanics, but omits repo removal, a minor coverage gap. Not 5 because the full repo surface (list/remove) isn't covered; not 3 because it goes well beyond naming 1-2 actions.

Completeness

The "what" is clear (three named capabilities with a guided-conversation mechanic), but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. Not 4 because the "when" is entirely absent rather than merely implicit.

Trigger Term Quality

Relevant keywords are present ("Add a repo", "inspect the registry", "repair a repo's footprint") but common natural variations users would say — "register a repo", "list repos", "what repos are in this project", "remove a repo" — are missing. Not 4 because several natural phrasings are absent; not 2 because the terms present are domain-specific and natural rather than generic.

Distinctiveness Conflict Risk

"Spektacular project", "repo", "footprint" carve a clear niche with repo-scoped triggers, giving minimal conflict risk with unrelated skills. Not 5 because sibling Spektacular skills (init, plans, changelog surfaces) plausibly exist and repo-adjacent phrasing could overlap slightly; not 3 because the scoping is distinctly about repo management.
