Quality

Content

72%

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 highly actionable with a concrete schema and decision rules, but the workflow lacks an explicit validation checkpoint and the stop-and-wait guidance is redundantly stated. It is appropriately concise for a single-purpose configuration skill.

Suggestions

Add an explicit validation step to the workflow, e.g. 'Before writing gallery.json, confirm every item src resolves to a real file found in step 2.'

Consolidate the stop-and-wait instruction so it appears once rather than in both the Workflow and 'Working with the user' sections.

Optionally state how to handle the case where no media is found (the 'Don't suggest uploading' rule implies it but no positive fallback is given).

DimensionReasoningScore

Conciseness

The body is lean with no concept-explanation padding, but the stop-and-wait protocol is restated in both the Workflow and 'Working with the user' sections and could be tightened.

2 / 3

Actionability

Provides a complete copy-paste-ready JSON schema, a concrete Glob pattern, and a specific decision rule for viewMode with numeric thresholds — fully actionable guidance.

3 / 3

Workflow Clarity

The five-step sequence is clear, but there is no explicit validation checkpoint (e.g., verifying that all referenced media src paths exist before writing gallery.json), leaving verification implicit.

2 / 3

Progressive Disclosure

A single well-organized SKILL.md with clear sections (Schema, Workflow, Don't, Working with the user) and no external bundle files; appropriately self-contained for a simple skill.

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 is clear and third-person but mid-range: it conveys what the skill configures without explicit when-to-use triggers or a comprehensive action list. It is distinguishable but not strongly differentiated.

Suggestions

Add a 'Use when...' clause with natural trigger terms (e.g., 'Use when the user wants a photo/video gallery, a media library app, or categorised image and video collections').

List concrete actions explicitly (e.g., 'Scan project media, group into categories, set view modes, and generate gallery.json').

Include common user phrasings like 'photo gallery', 'video gallery', or 'media library' to improve trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain and concrete capabilities ('categorised images and videos with multiple view modes') but does not enumerate multiple distinct actions like the score-3 anchor does.

2 / 3

Completeness

Clearly states what the skill does, but the description field lacks a 'Use when...' clause or equivalent trigger guidance, capping completeness at 2 per the rubric.

2 / 3

Trigger Term Quality

Contains relevant natural terms ('Gallery app', 'images', 'videos', 'view modes') but lacks common user variations and explicit trigger phrases a user would naturally say.

2 / 3

Distinctiveness Conflict Risk

'Gallery app' with categorised media and view modes is a somewhat specific niche, but without distinct explicit triggers it could still overlap with other media/app packaging skills.
