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 content is highly actionable with executable commands and copy-paste examples, and it appropriately delegates implementation to a real bundled script. Weaker spots are minor redundancy in the script-handles-everything messaging and the absence of explicit error-recovery guidance for failure cases like failed downloads or archives lacking a SKILL.md.

Suggestions

Remove the redundant 'Do NOT manually download or unzip — the script handles everything' line, since the preceding bullets already state the script handles everything automatically.

Add a short error-recovery note for failure cases, e.g. what to do if the URL download fails or the archive contains no SKILL.md, to add an explicit validation/feedback checkpoint.

Clarify the SKILL_DIR placeholder once near the command (e.g. note that the harness substitutes the skill directory path) so the example is unambiguously executable as written.

DimensionReasoningScore

Conciseness

The body is largely lean with no concept-explanation padding, but the note "Do NOT manually download or unzip — the script handles everything" repeats the preceding bullet list ("The script handles everything automatically"), so it could be tightened; not verbose enough to score 1.

2 / 3

Actionability

It gives a fully executable command with defined arguments (ruby ...install_from_zip.rb <zip_url_or_path> [slug]) and two copy-paste-ready examples covering both remote-URL and local-path inputs, matching the score-3 anchor.

3 / 3

Workflow Clarity

The single delegated action is unambiguous and the script's responsibilities are listed, but there are no explicit validation or error-recovery checkpoints (e.g. what to do if the download fails or no SKILL.md is found), so it sits at the score-2 'checkpoints missing or implicit' level rather than 3.

2 / 3

Progressive Disclosure

SKILL.md is a concise overview that delegates implementation to the bundled scripts/install_from_zip.rb, referenced by explicit one-level-deep path (verified to exist), with well-organized sections — matching the score-3 anchor for a simple skill with a single bundled reference.

Description

90%

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 strong: it specifies a clear, distinctive niche, answers both what and when with explicit triggers, and covers natural user phrasings including the /skill-add command and Chinese variants. The only mild weakness is that the capability description centers on a single verb (install) rather than enumerating several distinct concrete actions.

DimensionReasoningScore

Specificity

It names the primary action ("Install skills") and the two concrete input types ("zip URL or local zip file path"), but does not enumerate multiple distinct operations like the score-3 PDF example; it is concrete rather than vague, so above 1.

2 / 3

Completeness

It clearly states what (install skills from a zip URL or local path) and when ("Use this skill whenever the user wants to install a skill from a zip link or a local file") with explicit trigger phrases, matching the score-3 what-and-when pattern.

3 / 3

Trigger Term Quality

Broad coverage of natural phrasings ("install skill", "install from zip", "skill from url", "add skill from zip") plus the explicit /skill-add command and bilingual triggers, matching the score-3 anchor's breadth of user-sayable terms.

3 / 3

Distinctiveness Conflict Risk

It occupies a clear niche (installing skills specifically from zip archives/URLs) anchored by the distinctive /skill-add command and zip-specific triggers, making conflict with other skills unlikely.
