Conciseness

The body is lean with no concept explanations and defers payload schemas to the OpenAPI spec. Minor waste keeps it below 5: the Overview repeats the frontmatter description verbatim, and redundant breadcrumb lines like 'GET system › env › repair' duplicate each heading. It is well above 3, which requires noticeably unnecessary explanation.

Actionability

The curl commands are executable, but the POST examples send empty bodies ('-d {}') with no indication of required payload fields, and there is not a single example of the skill's stated purpose — triggering a backup, restoring from a file, or importing a snapshot. Concrete guidance exists but key details are missing, matching the 3 anchor rather than 4.

Workflow Clarity

No sequence exists for the backup/restore lifecycle at all — the documented endpoints (env/repair, version) are unrelated to backups, so a user cannot determine steps for backup, restore, or export/import. Restoring from a backup is a destructive operation with no validation or verification guidance, which per the guidelines caps workflow clarity at 3; the absence of any sequence places it at 2.

Progressive Disclosure

Short, sectioned body with payload details correctly deferred one level to 'GET /api/openapi/spec' or 'docs/openapi.yaml'. Not 5 because 'docs/openapi.yaml' is not part of the bundle (no references/ directory exists), and the inline endpoint details do not cover the skill's actual subject matter. Well above 3 — structure and navigation are clear.

Specificity

The description lists several concrete actions — 'Trigger system backups, restore from backup files' plus 'export, import, and incremental snapshot strategies' — but 'manage the SQLite database lifecycle' is generic, leaving minor gaps in coverage. Not 5 because that phrase is not a fully concrete action; clearly above 3, which covers only 1-2 actions.

Completeness

The 'what' is clear (backup, restore, SQLite lifecycle management), but there is no 'when' clause at all — no 'Use when...' or equivalent trigger guidance. Per the judging guidelines a missing trigger clause caps completeness at 3; it is not 2 because the 'what' is concrete rather than vague.

Trigger Term Quality

Good natural keywords users would say: 'backups', 'restore', 'backup files', 'export', 'import', 'SQLite'. Not 5 because common variations are missing — e.g., 'dump', '.db'/' .sqlite' file extensions, and phrasings like 'back up the database'.

Distinctiveness Conflict Risk

A clear niche — SQLite database backup/restore/snapshot management — with distinctive terms that are unlikely to collide with unrelated skills. Minor overlap risk with general database-administration skills keeps it below 5.
