Conciseness

Lean and well-sectioned with no padding of concepts Claude already knows; the runtime-budget rationale in "Why" is genuinely non-obvious domain context that earns its tokens, fitting the level-3 anchor.

Actionability

Concrete, specific instructions with example proof statements ("saved 12 of 12 panels (ids …)", "updated 5 rows") and a precise verify procedure; per the instruction-only scoring note, the absence of code is not penalized because the guidance is actionable.

Workflow Clarity

The "How" section gives a clear 5-step sequence with an explicit verification checkpoint (step 3, before reporting) and a fail-loud feedback loop for time-budget cutoffs (step 5), matching the anchor for sequenced steps with validation and error recovery.

Progressive Disclosure

A single self-contained SKILL.md (~62 lines) with well-organized Rule/Why/How/Don't/Related sections and only one-level cross-skill pointers; no bundle files exist and none are needed, so well-organized sections satisfy the level-3 simple-skill anchor.

Specificity

Lists multiple concrete actions — "create, update, delete, or batch-write app data" — matching the anchor for enumerating several specific concrete verbs, not the level-2 single-domain example.

Completeness

Explicitly answers what ("perform writes so they actually persist under the hosted foreground run budget and long-running background handoffs") and when ("Use whenever you create, update, delete, or batch-write app data ..."), matching the what-AND-when anchor.

Trigger Term Quality

Natural trigger phrasings a user would say appear in "do this for many items" loops and "expects N things to end up saved", with good variation; not level 2 because it goes beyond a single keyword to several natural formulations.

Distinctiveness Conflict Risk

The reliable-persistence-under-budgets niche is fairly distinct, but the broad "create, update, delete app data" triggers overlap with the related `actions` and `storing-data` skills it itself cites, so it is not yet a clear, conflict-free niche.
