Conciseness

The body is a lean two-sentence overview plus a numbered index of 17 reference files — no padding, no explanation of concepts Claude already knows, no duplicated content. Every token earns its place. It is clearly the level-5 anchor, not level 4, because there is not even minor over-explanation to trim.

Actionability

The body provides concrete scope pointers ('/packages/css/src/scss/', '@oslokommune/punkt-css') but zero executable guidance — no code, commands, naming examples, or steps, delegating everything to 17 referenced files. This matches 'minimal concrete guidance; high-level hints but missing the specific steps to execute' rather than level 1, because the domain references are specific rather than vague; it cannot reach level 3-4 because no instruction or example of any kind appears in the body itself.

Workflow Clarity

No multi-step process is written anywhere in the body; even the implied workflow ('Checklist: Adding Component Styles') exists only as an index entry. This sits between level 1 ('steps missing; no sequence') and level 2 ('rough sequence present'), scoring 2 because the coherent index signals where the sequence lives, but no steps or validation checkpoints are actually stated. No destructive/batch operation is described, so the workflow cap does not apply.

Progressive Disclosure

The link structure itself is clean — 17 one-level-deep, clearly named, numbered references — but two problems hold it at the middle anchor: the SKILL.md body contains no overview/getting-started content beyond restating the description, and none of the 17 referenced files exist in the bundle (no references/ directory), so the links are dead here and navigation cannot be verified. Not level 2 since nothing is inlined or buried, but not level 4-5 since the split cannot be confirmed and the body adds no orienting content.

Specificity

The description names the domain precisely ('Developing component and utility styles in the Punkt design system (@oslokommune/punkt-css)' with a concrete SCSS path), but the actions 'creating, modifying, and maintaining' are near-synonymous generic verbs rather than distinct concrete capabilities, matching the anchor 'names domain and 1-2 concrete actions, but not comprehensive'. It is above level 2 because the domain and artifact are specific, not generic, but below level 4 because the verb list collapses into a single action (writing styles) with no differentiated capabilities.

Completeness

It explicitly answers both parts: what ('Covers creating, modifying, and maintaining SCSS in /packages/css/src/scss/') and when ('Use when working on Punkt CSS source code'), matching the anchor 'has both what and when; when could be more explicit or specific'. It is not level 5 because the trigger is a single clause without additional concrete trigger phrases or synonyms.

Trigger Term Quality

Natural terms users of this system would actually say are present: 'Punkt design system', '@oslokommune/punkt-css', 'SCSS', and 'Punkt CSS source code', giving good keyword coverage. It falls short of level 5 because common variations like 'styles', 'stylesheet', 'design tokens', or 'Oslo Kommune' are absent.

Distinctiveness Conflict Risk

The description occupies a clear niche anchored by the unique package name '@oslokommune/punkt-css' and repo-relative path, with triggers ('Punkt CSS source code') that would not fire for unrelated skills — minimal conflict risk.
