Conciseness

The body is efficient — a parameter table, a JSON example, and a short decision tree with no explanations of concepts Claude already knows. Not level 5 because the mandatory preamble repeats the frontmatter's enforcement language, and the paragraph 'Parse the arguments from the skill invocation. If editorType is not provided, default to design...' restates the defaults already given in the bullet list above it.

Actionability

Fully executable guidance: exact tool name, parameter table with required flags, a copy-paste-ready JSON call example, the tool's return fields (file_key, file_url), and the explicit next step ('Use the file_key for subsequent tool calls like use_figma'). Nothing is pseudocode or vague; not lower on any anchor.

Workflow Clarity

A clear three-step sequence with a planKey decision tree that handles the ambiguous multiple-plans case by asking the user — a real checkpoint. Not level 5 because there are no explicit validation or error-recovery steps (e.g. what to do if whoami returns an empty plans array or the tool call fails), and the anchor-5 example includes feedback loops.

Progressive Disclosure

Well-organized single-file skill: sections are clear, and the slides edge-case detail is appropriately deferred via a clearly signaled one-level reference ('See [figma-use-slides → slide-grid](../figma-use-slides/references/slide-grid.md)'). Not level 5 because the body is ~73 lines rather than under 50, and the sole reference points into a sibling skill's bundle rather than this skill's own, which is slightly unusual navigation though functional.

Specificity

The description lists several concrete capabilities — creating a new blank Figma file in 'a new design, FigJam, or Slides file' variants, acting as prerequisite before 'use_figma', with usage syntax and two concrete invocation examples. It is not level 5 because the capability statement is thin relative to the mandatory framing, and the rubric's second-person voice penalty ('you MUST invoke', 'when you need a fresh file') reduces it from 5 to 4.

Completeness

Both 'what' (creating a new blank Figma file of the three editor types) and 'when' (explicit 'Trigger whenever the user wants a new blank Figma file... or when you need a fresh file before calling use_figma') are present. Not level 5 because the 'what' is embedded in trigger phrasing and mandatory rhetoric rather than stated as a leading, direct capability sentence as in the anchor-5 example.

Trigger Term Quality

Good natural keyword coverage: 'new blank Figma file', 'new design', 'FigJam', 'Slides file', 'fresh file', plus tool names create_new_file and use_figma. Not level 5 because common synonyms users would say — 'whiteboard', 'presentation', 'deck' — are absent except obliquely in the example 'Q3 Review'.

Distinctiveness Conflict Risk

Clear niche with distinct triggers — Figma file creation specifically, anchored to the create_new_file and use_figma tool names and the three editor types, which distinguishes it from other Figma skills like figma-use. Minimal conflict risk; not lower because no generic language remains that would overlap sibling skills.
