portaljs-add-dcat

Make a PortalJS portal harvestable by national/EU/US open-data portals — emit standards-compliant DCAT catalog feeds (DCAT 2/3, DCAT-AP, DCAT-US, national profiles) in JSON-LD, Turtle, and RDF/XML at build, with autodiscovery and per-profile conformance checking. Use when a portal needs to be harvested by data.europa.eu, data.gov, or a national open-data catalog.

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 well-organized, validation-rich skill body that delegates detail to a real reference file and keeps the SKILL.md as an actionable overview. Slight reliance on an external URL for the full workflow and minor verbosity are the only gaps.

Dimension	Reasoning	Score
Conciseness	Largely lean overview with an 10-step summary, error table, and examples rather than padded explanation; minor verbosity in the Overview and Output bullets could be trimmed further.	4 / 5
Actionability	Concrete commands (npm run generate:dcat, npx next build), exact file paths, and named validators, but the canonical executable steps are delegated to an external URL rather than inlined.	4 / 5
Workflow Clarity	Clear 10-step sequence with explicit validation checkpoints (confirm contracts, surface missing fields, SHACL/ITB validation, next build), error-handling table, and feedback loops for fixes.	5 / 5
Progressive Disclosure	Well-structured overview pointing one level deep to references/reference.md and an external canonical command file; the reference file exists and is clearly signaled.	5 / 5

Description

92%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 strong, third-person description that names concrete capabilities and an explicit trigger. It is specific, complete, and distinct within the PortalJS skill family; only minor synonym coverage in trigger terms keeps it from a perfect run.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions (emit standards-compliant DCAT catalog feeds, conformance checking, autodiscovery) across several profiles and three serialization formats, with comprehensive coverage.	5 / 5
Completeness	Explicitly states what it does ('emit standards-compliant DCAT catalog feeds ... in JSON-LD, Turtle, and RDF/XML at build') and when to use it ('Use when a portal needs to be harvested by data.europa.eu, data.gov, or a national open-data catalog').	5 / 5
Trigger Term Quality	Strong natural terms ('harvestable', 'data.europa.eu', 'data.gov', 'open-data portals') but lacks synonym variants and the literal phrase a user might say ('DCAT feed', 'open data catalog').	4 / 5
Distinctiveness Conflict Risk	Clear niche (PortalJS DCAT harvesting) with distinct triggers tied to named portals and DCAT profiles; minimal conflict risk with sibling PortalJS skills.	5 / 5
