Quality

Content

57%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a lean, well-organized catalogue stub that clearly redirects to the upstream bundle, scoring well on progressive disclosure. However, it provides little actionable guidance for the skill's actual purpose and no concrete install command or validation steps, capping actionability and workflow clarity at 2.

Suggestions

Replace the vague "install the upstream bundle into your active agent's skills directory" with the actual install command and exact target path so the setup is copy-paste ready.

Add at least a minimal inline quick-reference (e.g. Anthropic's primary hex values and font families) so the skill is actionable without always round-tripping to the upstream repo.

Drop the verbatim repetition of the frontmatter description in "What it does" and the meta line "A reference for shaping your own" to tighten conciseness toward 3.

DimensionReasoningScore

Conciseness

The body is short and lean, but the "What it does" section repeats the frontmatter description verbatim and includes meta phrases ("Curated from Anthropic's official skills repository", "A reference for shaping your own"), so it is mostly efficient but could be tightened — the 2 anchor rather than the 3 anchor where every token earns its place.

2 / 3

Actionability

It offers one concrete command ("open https://...") and a clear invoke-by-name instruction, but the central action ("install the upstream bundle into your active agent's skills directory") has no actual command and there is no executable guidance for applying brand colors/typology, matching the 2 anchor (some concrete guidance but incomplete, missing key details) rather than the fully executable 3 anchor or the purely descriptive 1 anchor.

2 / 3

Workflow Clarity

A loose three-step sequence is present (inspect the upstream README, install the bundle, invoke by name or trigger), but the steps are vague and lack any validation checkpoints, fitting the 2 anchor (sequence present but checkpoints missing/implicit) rather than the 3 anchor's explicit validation steps.

2 / 3

Progressive Disclosure

The body is under 50 lines and organized into clear sections (What it does, Source, How to use) with a single clearly-signaled one-level-deep external reference (the upstream GitHub URL); per the scoring notes, short well-organized skills with no need for local references can score 3, placing it above the 2 anchor's poorly-organized inline content.

Description

50%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description clearly identifies the domain (Anthropic brand colors and typography) and a couple of concrete actions, but stops short of comprehensive specificity and lacks an explicit "Use when..." trigger clause, capping completeness at 2. It is moderately distinctive but the broad word "artifacts" leaves some overlap risk with general design skills.

Suggestions

Add an explicit "Use when..." clause naming natural trigger phrases (e.g. brand colors, brand typography, visual identity, company design standards) to lift completeness and trigger-term coverage to 3.

Replace the meta phrase "A reference for shaping your own" with additional concrete capabilities (e.g. applying hex color values, font families, spacing tokens) to improve specificity.

Tighten "artifacts" to a more specific scope (e.g. "HTML/CSS artifacts, slides, and documents") to reduce conflict risk with general styling skills.

DimensionReasoningScore

Specificity

"Apply Anthropic's official brand colors and typography to artifacts" names two concrete actions, but the remainder ("consistent visual identity and professional design standards. A reference for shaping your own.") is meta-fluff; it names the domain and some actions but is not comprehensive, fitting the 2 anchor rather than the 3 anchor's multiple specific actions.

2 / 3

Completeness

The description states what the skill does but contains no "Use when..." clause; per the judging guidelines a missing explicit trigger clause caps completeness at 2, so it is not the 3 anchor (which requires explicit when-triggers) nor the 1 anchor (which would lack a clear what).

2 / 3

Trigger Term Quality

It includes relevant keywords ("brand colors", "typography", "visual identity", "professional design standards") but misses common natural variations users would say (e.g. "branding", "logo", "style guide"), matching the 2 anchor of some relevant keywords missing common variations rather than the 3 anchor's good coverage.

2 / 3

Distinctiveness Conflict Risk

"Anthropic's official brand colors" gives it a recognizable niche, but "artifacts" is broad and could overlap with general styling/design skills, matching the 2 anchor (somewhat specific but could still overlap) rather than the 3 anchor's clearly distinct triggers.
