Quality

Content

82%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.

A highly actionable, well-organized single-file skill with complete executable guidance and explicit error handling. Remaining gains are small: describe the success response shape, add an output verification step, and de-duplicate the base-URL/port information.

DimensionReasoningScore

Conciseness

The body is operational detail only — endpoint, port/token resolution, fields, error handling — with no concepts Claude already knows explained. Minor trimmable redundancy exists: the base-URL resolution order and the "Common local ports" list both cover 8648, and the example script re-walks the documented token chain.

4 / 5

Actionability

The curl example is fully executable and copy-paste ready, with a complete token fallback chain, all required and optional JSON fields specified with defaults and ranges, and a concrete error response path ("missing_xai_token" with user-facing remediation).

5 / 5

Workflow Clarity

The sequence is clear — resolve base URL, resolve token, optionally add X-Hermes-Profile, POST, handle 401/403/connection/missing_xai_token errors, return output_path. It falls short of 5 because the success response format is not described (how to identify output_path/request_id in the response) and there is no step verifying the mp4 was saved.

4 / 5

Progressive Disclosure

No bundle files exist and the skill is a single well-sectioned file with no nested references and easy navigation. It does not reach 5 because the file is over the lean single-file size, and the environment/port catalog (dev, desktop, Docker Compose ports) is reference-style detail that could live in a separate reference file.

Description

70%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.

A concise, specific, third-person description with strong distinctiveness, but it lacks an explicit use-when trigger clause. Adding trigger phrasing and a few natural synonyms would make it fully complete.

Suggestions

Add an explicit trigger clause, e.g. "Use when the user wants to animate an image, turn a picture into a video, or generate a short clip from a local image."

Include common user phrasings and synonyms such as "image to video", "make a video from a picture", and "Grok Imagine" to improve trigger term coverage.

Optionally mention the prompt/duration control (motion and style instructions, 1–15 second clips) to round out the capability coverage in specificity.

DimensionReasoningScore

Specificity

"Animate a local image into a short mp4 video" names the input, output format, and mechanism ("through Hermes Web UI using xAI Grok Imagine"), making the single action fully concrete. It stops short of the 5 anchor because it lists only one action and omits controllable aspects like motion prompt or duration.

4 / 5

Completeness

The "what" is clear and concrete, but there is no "Use when…" clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. The "when" is only weakly implied by "local image".

3 / 5

Trigger Term Quality

Natural keywords are present — "animate", "image", "video", "mp4", "Grok" — covering the phrases a user would say. A few natural variations are missing (e.g. "image to video", "make/turn a picture into a video", "Grok Imagine"), so it does not reach comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

"xAI Grok Imagine" image-to-video "through Hermes Web UI" is a clear niche with distinct trigger terms and minimal overlap risk with other media or video skills.
