Quality

Content

61%Weight 40%Scale 1-5

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

The body is well-structured and concise with clear visual targets and tuning knobs, but it lacks executable code and has an empty Workflow section, leaving the creation sequence implicit. Adding a concrete minimal implementation and populating the workflow would materially improve it.

Suggestions

Populate the empty "## Workflow" section with an explicit ordered sequence (e.g., set base palette -> layer vertical fold bands -> apply screen blending -> add focal bloom -> tune motion), ideally with a validation step to confirm the result reads as calm atmospheric light.

Add at least one minimal executable example (canvas 2D or shader snippet) showing the fold-band + screen-blend + radial bloom technique so the guidance is copy-paste ready rather than purely descriptive.

Tighten a few Implementation guidance bullets that restate the Visual target (e.g., fold shaping and focal brightness appear in both sections) to reduce redundancy.

DimensionReasoningScore

Conciseness

The body is lean and uses tight bullet points without explaining concepts Claude already knows (e.g., it does not lecture on what canvas or shaders are); only minor phrasing could be trimmed, and every section earns its place.

4 / 5

Actionability

Guidance is directive and fairly concrete ("Use multiple tall overlapping bands... with slow sine-wave drift", "Use screen or additive-style blending") but provides no executable code or commands for a canvas/shader effect, leaving the actual implementation to inference.

3 / 5

Workflow Clarity

The "## Workflow" section header is present but empty, and the steps are spread across Visual target / Implementation guidance / Tuning knobs with no explicit sequence or checkpoints, so the workflow is implied rather than clearly sequenced.

3 / 5

Progressive Disclosure

The skill is under 50 lines with no external references needed, and sections (Use When, Scope, Visual target, Implementation guidance, Tuning knobs, Avoid) are well organized; the empty Workflow header is the main structural blemish.

Description

66%Weight 40%Scale 1-5

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 is specific and distinct, naming several concrete visual characteristics of the target effect. Its main weakness is the absence of an explicit "Use when..." trigger clause, which leaves the "when to invoke" question unanswered.

Suggestions

Add an explicit "Use when..." clause naming concrete triggers, e.g. "Use when the design needs a dark moody backdrop with drifting light folds or a cinematic corner bloom."

Include common synonyms/file-context terms users might say ("moody background", "ambient backdrop", "light curtains") to broaden natural trigger coverage.

DimensionReasoningScore

Specificity

Lists several concrete visual features ("drifting vertical light folds", "screen-blended glow", "concentrated luminous corner or lower-edge bloom") rather than vague language, though they describe visual characteristics more than discrete actions.

4 / 5

Completeness

The "what" is clear (create a dark atmospheric background with specified glow features) but there is no explicit "Use when..." trigger guidance in the description, which caps completeness at 3 per the rubric.

3 / 5

Trigger Term Quality

Contains natural design terms a user might say ("dark atmospheric background", "light folds", "glow", "bloom") with good coverage, though a few common synonyms are missing.

4 / 5

Distinctiveness Conflict Risk

The niche (atmospheric vertical-light-fold backgrounds) is fairly distinct with minimal overlap risk against other skills, though it could still marginally overlap with generic background-creation skills.
