Quality

Content

100%

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

An executable, well-sequenced skill body: concrete commands, a clear two-decision workflow with validation gates, and clean organization with no unnecessary explanation.

DimensionReasoningScore

Conciseness

The body is dense and efficient: tables, command blocks, and tight prose that assume Claude's competence, with no padding explaining what Windmill or a browser is — every section earns its place.

3 / 3

Actionability

It provides fully executable commands ('wmill dev --path <wmill_path> --no-open', 'wmill app dev --no-open --port 4000') and copy-paste launch.json entries with concrete line-shape cues for capturing URLs.

3 / 3

Workflow Clarity

The two independent decisions are decomposed into a decision matrix, and the launch.json path is sequenced as explicit Step 1/Step 2 with conditional gates ('Only take this path if…') and an anti-patterns section for error avoidance.

3 / 3

Progressive Disclosure

No bundle files exist, and the self-contained body is well-organized into clearly signaled sections, satisfying the simple-skill allowance for progressive disclosure.

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.

A strong description with explicit trigger guidance and a clear Windmill-specific niche; its only weakness is that it names a single primary action rather than a list of concrete capabilities.

DimensionReasoningScore

Specificity

It names the domain ('Windmill dev page / visual preview of a flow, script, or app') and the core action (opening the preview), but lists only one concrete action rather than multiple specific operations, matching the 'names domain and some actions, but not comprehensive' anchor.

2 / 3

Completeness

'MUST use when opening…' answers when, and 'visual preview of a flow, script, or app' answers what, with an explicit 'Use when' trigger clause — both halves are clearly present.

3 / 3

Trigger Term Quality

It explicitly enumerates natural trigger words ('preview, open, navigate to, visualize, see the flow/app/script') plus a post-authoring condition, giving good coverage of terms a user would actually say.

3 / 3

Distinctiveness Conflict Risk

Triggering is pinned to the Windmill dev page and flow/script/app preview, a clear niche unlikely to fire for unrelated skills.
