Conciseness

The body is dense with genuinely non-obvious operational rules (little explanation of things Claude already knows), but it carries noticeable repetition and inlined reference-grade material: Rule 9 is restated across Section 2, Rule 5 across Sections 5–6, Section 3 restates Rules 4/15, the Pre-Flight Checklist (Section 8) re-enumerates Rules 1–18, and the full `node.query` selector grammar plus QueryResult method table plus editor-mode node-type lists would fit better in a reference file. This matches the 3 anchor ('mostly efficient but… could be tightened') better than 2 ('several unnecessary explanations or padded sections') since nearly all content is novel, not padding — and better than 4 given the 380-line body in a bundle that already ships 12+ reference files.

Actionability

Guidance is fully executable: copy-paste inspection scripts (e.g. `figma.root.children.map(p => ({ id: p.id, name: p.name }))`), exact error strings to expect ('"Setting figma.currentPage is not supported"', 'Expected \'FIXED\' | \'AUTO\', received \'FILL\''), WRONG/CORRECT code contrasts, and precise API recipes with argument shapes. This matches the 5 anchor: 'copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

Section 6 gives a numbered step order with a per-step validation table ('What to validate at each step'), Section 7 defines an explicit feedback loop (obey `safeToRetryWithoutCanvasRead`, targeted fix scripts, root-cause rule on repeated errors), and Section 8 provides a pre-flight checklist. This is the 5 anchor: 'clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'.

Progressive Disclosure

The reference docs table in Section 10 is a model of clear signaling (per-file 'When to load' and 'What it covers' columns) and all referenced paths resolve to real files in references/. However, the `working-with-design-systems/` chain nests three levels deep (SKILL.md → wwds.md → wwds-components.md → wwds-components--creating.md), and some reference-grade content (selector grammar, QueryResult method table, editor-mode node-type lists) is inlined in the overview. This fits the 4 anchor ('good structure; most content appropriately placed; references mostly clear; minor organization gaps') rather than 5, and is well above 3 since the primary navigation is explicit and easy to use.

Specificity

The description lists multiple concrete actions — 'create/edit/delete nodes, set up variables or tokens, build components and variants, modify auto-layout or fills, bind variables to properties, or inspect file structure programmatically' — which matches the 'lists several specific actions; minor gaps in coverage' anchor (5-level coverage minus one point for the second-person voice 'you MUST invoke this skill', which the guidelines explicitly penalize). It is well above the 3 anchor ('1-2 concrete actions') because the action list is comprehensive, but not a clean 5 due to the voice penalty.

Completeness

The 'when' is maximally explicit ('Trigger whenever the user wants to perform a write action or a unique read action…' plus e.g. instances), but the 'what' — that this skill provides the operating rules and reference docs for the `use_figma` Plugin API — is only implied by 'requires JavaScript execution in the Figma file context'. This sits at the 4 anchor ('has both what and when' with one of them improvable) rather than 5, where both would be explicitly and concretely stated; it is clearly above 3 since the trigger guidance is explicit, not weakly implied.

Trigger Term Quality

Natural Figma-domain terms are well covered — 'nodes', 'variables or tokens', 'components and variants', 'auto-layout', 'fills', 'bind variables', 'inspect file structure' — matching the 'good keyword coverage; a few natural terms missing' anchor. Not a 5 because phrases like 'unique read action that requires JavaScript execution in the Figma file context' are harness jargon rather than words a user would naturally say, and common variations (styles, effects, prototypes, screenshots) are absent.

Distinctiveness Conflict Risk

The description is bound to a single named tool ('BEFORE every `use_figma` tool call') with a clear niche and distinct triggers (node writes, variable/token setup, component/variant building, binding), matching the 'clear niche with distinct triggers; minimal conflict risk' anchor. It is not a 4 because the prerequisite framing actively reduces overlap risk with sibling Figma skills — any use_figma call routes here first.
