Quality

Content

85%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 tightly structured, actionable skill body that delegates the full canonical workflow to a remote source of truth while keeping a clear, validated 10-step summary and a useful error-recovery table. Only slight redundancy between the Overview and Instructions keeps conciseness from a perfect score.

DimensionReasoningScore

Conciseness

The body is efficient and assumes Claude's competence, but the Overview and the Instructions summary both narrate the same workflow, a minor redundancy that keeps it just below the every-token-earns-its-place 5.

4 / 5

Actionability

Concrete commands (`npx tiged ...`, `perl -pi`, `npm install`, `npx tsc --noEmit`), exact tokens, and file paths are present, but the fully executable workflow is delegated to the remote canonical file rather than inline, leaving minor gaps versus copy-paste-ready 5.

4 / 5

Workflow Clarity

A clear 10-step sequence with explicit validation (tsc --noEmit, never next build), a pre-overwrite directory check at step 4, and a symptom/cause/fix error table providing feedback loops for recovery matches the explicit-validation-with-feedback-loops 5 anchor.

5 / 5

Progressive Disclosure

The body is an overview that signals one-level-deep references to the canonical remote workflow and the verified local references/reference.md, with content appropriately split across clearly headed sections (Overview, Prerequisites, Instructions, Output, Error Handling, Examples, Resources).

Description

78%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 well-constructed description that cleanly answers what the skill does and when to invoke it, with natural trigger phrasing and concrete actions. The only weakness is modest trigger-term breadth and minor overlap with sibling PortalJS skills.

DimensionReasoningScore

Specificity

Names the domain ('PortalJS data portal') and two concrete actions ('Copies the canonical template from examples/portaljs-catalog and substitutes project tokens'), matching the 1-2-concrete-actions anchor rather than the 'several specific actions' of a 4.

3 / 5

Completeness

It explicitly answers both what ('Scaffold a new PortalJS data portal... Copies the canonical template... substitutes project tokens') and when ('Use when starting a brand-new data portal project from scratch') with a concrete trigger phrase, matching the 5 anchor exactly.

5 / 5

Trigger Term Quality

Natural phrases like 'data portal', 'brief', and 'starting a brand-new data portal project from scratch' give good keyword coverage, though synonyms like 'data catalog' and 'Next.js portal' are missing so it does not reach comprehensive 5.

4 / 5

Distinctiveness Conflict Risk

The 'new portal from scratch' trigger carves a clear niche, but sibling PortalJS skills (portaljs-add-dataset, add-chart, add-map) create minor overlap risk within the same family, so it sits at mostly-distinct 4 rather than minimal-conflict 5.
