Quality

Content

65%

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

The content is highly actionable and assumes Claude's competence, with concrete API contracts and a final validation checklist. Its weaknesses are conciseness (length and repetition), workflow sequencing, and the absence of any progressive file structure.

Suggestions

Consolidate the repeated preview-first and clipboard-preservation rules into a single stated contract referenced by each feature area to cut length and repetition.

Convert the key multi-step flows (preview-first commit, drag placement, template save/paste) into explicit numbered steps with validation checkpoints rather than prose.

Split per-subsystem detail (Stamps, Layers, Selection properties, Clipboard/templates) into reference files and keep SKILL.md as an overview that links one level deep.

Dimension	Reasoning	Score
Conciseness	The body is dense and assumes Claude's intelligence with no filler explanations, but at ~199 lines it is repetitive across sections (e.g. repeated preview-first/clipboard-preservation rules) and could be tightened.	2 / 3
Actionability	It gives concrete, specific guidance throughout — named functions like setCell(x,z,opts), replaceWorldCoords(), applyToolToCell(), applyState(); localStorage keys; and file paths — making the contract directly actionable even without runnable code blocks.	3 / 3
Workflow Clarity	A validation section (npm test, npm run build, browser-check list) exists, but most multi-step flows are described as prose rather than explicit numbered sequences with per-step checkpoints, and feedback loops are not consistently interleaved for each destructive operation.	2 / 3
Progressive Disclosure	No bundle files are present and the body is a monolithic single-file listing covering many subsystems via long bulleted lists with no external references or split navigation, though headers provide some organization.	2 / 3
	Total	9 / 12 Passed

Description

100%

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 concise, specific, and answers both what the skill does and when to use it with an explicit trigger clause. It is well-scoped to Tiny World Builder and unlikely to conflict with other skills.

Dimension	Reasoning	Score
Specificity	The description enumerates multiple concrete capability areas — "selection placement, freehand drawing, asset clipboard, cut/copy/paste/duplicate, saved templates, or Stamps panel navigation" — rather than vague language.	3 / 3
Completeness	An explicit "Use when changing ..." clause provides the when, while the enumerated list provides the what — both are clearly and explicitly answered.	3 / 3
Trigger Term Quality	It uses natural terms a Tiny World Builder user would actually say ("cut/copy/paste/duplicate", "freehand drawing", "saved templates", "Stamps panel"), giving good coverage of the skill's surface.	3 / 3
Distinctiveness Conflict Risk	It is scoped to the named product "Tiny World Builder" with distinct feature names (Stamps panel, asset clipboard), making it unlikely to trigger for unrelated skills.	3 / 3
	Total	12 / 12 Passed
