Conciseness

Lean and efficient throughout: no explanations of concepts Claude already knows, every sentence carries non-obvious guidance ('a successful command is not a visual quality verdict', 'Do not assume cwd or a previous shell variable persists'); not 4 because there is no padding to trim.

Actionability

Concrete, mostly executable commands for the full pipeline ('fireworks.py validate architecture input.json', 'render ... --report layout.json', 'check diagram.svg', 'export-png diagram.svg diagram.png --width 1920'), but both command blocks embed a literal placeholder path ('${CLAUDE_SKILL_DIR:-/absolute/path/from-codex-skill-metadata}'), so they are not fully copy-paste ready; not 3 because guidance goes well beyond high-level hints.

Workflow Clarity

Clear sectioned sequence (select → generate/check → additional outputs → verify) with explicit validation commands and a feedback loop: 'After a failed check, use its element IDs and geometry to make a focused repair; change the approach after two unchanged failures'; not 4 because checkpoints and error recovery are explicit, including skip-handling for unavailable image viewing.

Progressive Disclosure

Well-signaled one-level-deep markdown links (style-diagram-matrix.md, composition-quality-contract.md, png-export.md, motion-effects.md, etc.), all of which resolve to real files in references/ with no nested reference chains, plus explicit load-only-what's-needed guidance ('Read other styles only for a requested comparison'); not 4 because the split and navigation are clean throughout.

Specificity

Lists multiple specific concrete actions — 'Create precise SVG technical diagrams, export PNG or offline HTML, and animate supported semantic SVGs to GIF' — covering all output routes comprehensively; not 4 because there are no coverage gaps.

Completeness

Explicitly answers what (create SVG diagrams, export PNG/HTML, animate to GIF) and when ('Use for architecture, UML, agent, cloud or workflow diagrams; not photos, raster art or statistical charts') with concrete trigger phrases and explicit exclusions; not 4 because the when-clause is fully explicit.

Trigger Term Quality

Good natural trigger coverage ('architecture, UML, agent, cloud or workflow diagrams') but misses common synonyms and file extensions users would say, such as 'flowchart', 'sequence diagram', or '.svg'; not 3 because the included terms are natural and specific.

Distinctiveness Conflict Risk

Clear niche (technical/semantic SVG diagrams) with distinct triggers and explicit negative scope that fences off adjacent skills (photos, raster art, statistical charts); not 4 because conflict risk is minimal, not minor.
