Quality

Content

53%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 a lean, well-organized catalogue advertisement, but it defers everything substantive to the upstream repository and its single "command" (`open <url>`) is neither executable nor an installation step. The result is a skill whose content tells the agent what it advertises but not how to do anything.

Suggestions

Replace the `open https://github.com/MiniMax-AI/skills` snippet with a concrete, executable install step (e.g. `git clone` into a specific skills-directory path, or the exact subpath of the upstream bundle to copy).

Inline a minimal quick-start (the MiniMax API call or a single example command for converting one photo) so the skill is actionable even before the upstream bundle is installed.

Drop the verbatim duplicate of the frontmatter description in "What it does" and merge the "Source" section into it, since the upstream URL and category are already in the frontmatter.

DimensionReasoningScore

Conciseness

The body is short (~25 lines) with clean sections and no tutorials on concepts Claude already knows. Not 5 because it duplicates the frontmatter description verbatim in "What it does" and repeats the upstream URL and category in "Source", padding that could be trimmed.

4 / 5

Actionability

The only command is "open https://github.com/MiniMax-AI/skills" — a browser-open that is not executable on most agent hosts and installs nothing; the body says to "install the upstream bundle into your active agent's skills directory" but gives no install command, path, or any concrete step of the actual sticker-making workflow. This is high-level direction missing the specific steps to execute (score-2 anchor), not 3 because there is no partially-executable guidance at all.

2 / 5

Workflow Clarity

A rough sequence exists (inspect upstream README → install the bundle → invoke by name or trigger phrase), but each step is under-specified: no install command, no destination path, no verification that the bundle landed. The single-action simplicity exception does not lift it to 5 because the one action (installing the upstream bundle) is itself ambiguous and punts to an external repo.

3 / 5

Progressive Disclosure

No local bundle files exist (no references/, scripts/, or assets/), and the short body is organized into clearly headed sections (What it does / Source / How to use) with the upstream reference clearly signaled one level deep. Not 5 because the entire substantive payload is deferred to an external URL with no local content or navigable structure to split — the "How to use" section is a pointer, not an overview plus content.

Description

65%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 distinctive, naming a concrete action, a particular artistic style, and the MiniMax API, with good natural trigger terms. Its main weakness is the missing explicit "Use when..." trigger clause, which caps completeness, and it describes only a single action rather than a fuller capability list.

Suggestions

Add an explicit trigger clause, e.g. "Use when the user wants to turn photos into animated stickers, make Funko/Pop Mart-style chat stickers, or build avatar/表情 packs."

Mention one or two more concrete actions (e.g. batch-convert multiple photos, export looping GIFs at sticker-friendly sizes) to lift specificity from one action to several.

Fold the strongest natural trigger synonyms (e.g. "表情包", "sticker pack") into the description itself rather than keeping them only in the frontmatter triggers list.

DimensionReasoningScore

Specificity

"Convert photos into animated GIF stickers in Funko Pop / Pop Mart style via the MiniMax API" names the domain plus one concrete action with a specific style and API, but lists no other actions (no cropping, batch conversion, frame editing). This matches the score-3 anchor ('1-2 concrete actions, but not comprehensive'); score 4 requires several specific actions, which one action does not meet.

3 / 5

Completeness

The "what" is clear (photo-to-animated-GIF-sticker conversion via the MiniMax API), but "Useful for personalized chat stickers and avatar packs" is a use-case statement, not an explicit "Use when..." trigger clause — per the guidelines a missing 'Use when' clause caps completeness at 3. Not 2, because the what is concrete rather than vague.

3 / 5

Trigger Term Quality

The description contains natural terms users would say — "animated GIF stickers", "Funko Pop / Pop Mart style", "personalized chat stickers", "avatar packs" — giving good coverage. Not 5: it lacks common variations and synonyms (e.g. "表情包" and "funko sticker" live only in the frontmatter triggers, and no file-format terms appear).

4 / 5

Distinctiveness Conflict Risk

"Funko Pop / Pop Mart style" + "animated GIF stickers via the MiniMax API" carves out a clear niche with distinct triggers; minimal conflict risk with generic image-editing or sticker skills. Matches the score-5 anchor cleanly.
