Conciseness

Sections are lean one-line intros plus executable CSS ('Use the parent grid to enforce vertical and horizontal alignment.' followed by the grid block), but a few intro lines like 'Each section gets the same box model, line weight, and padding.' lightly restate what the code shows; not a 5 because of these minor redundant lead-ins.

Actionability

Fully copy-paste ready, executable CSS across all sections — design tokens, parent grid, .frame box model, L-shaped bracket background layers, span utilities, a responsive media query, and a complete HTML example — covering the common cases end to end.

Workflow Clarity

The numbered 'Layout Rules' (1–7) give a build sequence and the 'Quick Checks' section serves as a verification checklist, but the rules read more as a style checklist than a strict ordered workflow with explicit validation checkpoints; not a 5 because checkpoints are implicit rather than woven into the sequence.

Progressive Disclosure

Single self-contained file (~145 lines) with clearly organized sections in a logical build order (tokens → grid → frame → brackets → spans → example → taste → checks) and no nested references; not a 5 because no bundle files exist and the cohesive CSS slightly exceeds the under-50-line simple-skill threshold, though splitting would be artificial.

Specificity

Quotes a single concrete verb 'Create minimal framed grid layouts' but enumerates several specific visual features ('thin visible boundary lines, L-shaped corner brackets, subtle diagonal line texture, and strict section alignment'); not a 5 because it lists one action with feature sub-points rather than multiple distinct actions.

Completeness

Explicitly answers both what ('Create minimal framed grid layouts with...') and when ('Use when asked for clean, neutral, precise, structured, editorial, technical, or guide-border web layouts') with concrete trigger phrases, matching the anchor 5 example structure; voice is third person (no first/second person).

Trigger Term Quality

The 'Use when asked for clean, neutral, precise, structured, editorial, technical, or guide-border web layouts' clause gives good natural adjective coverage users would say, but the terms are somewhat abstract and lack concrete artifact synonyms; not comprehensive enough for a 5.

Distinctiveness Conflict Risk

'Framed grid layouts' with L-shaped corner brackets and diagonal texture is a distinct niche, but the broad 'clean, structured, editorial, technical web layouts' triggers create minor overlap risk with general layout/grid skills, keeping it just below a 5.
