Understand and reassess a resource's usefulness score

Assessed 2026-10-10 (America/Denver). Rubric version 1. Covers all 71 catalog rows, including hidden drafts and excluded resources.

What the number means

The rating is an editorial assessment of how useful the recorded resource is for learning, deciding, or evaluating an agent-skills workflow. It measures the information available in this library's catalog and the existing guides identified below. It is not an installation recommendation, a security score, a popularity measure, or a tested performance guarantee. A high score can accompany unresolved risks when the resource helps a reader understand those risks.

These assessments use the catalog snapshot at commit 02bd1ffe5a06024f89789a4886132f945efb7011 and existing repository guides. External catalog targets were not freshly audited for this rating pass. No catalog package was installed or executed, no benchmark was rerun, and no current availability, maintenance, or safety claim is implied. A catalog-only assessment is an inference from its recorded title, URL, summary, and scope. A catalog-and-guide assessment also uses the linked guide content; any prior scan or benchmark retains that guide's original date, artifact, and limitations. The assessment date is separate from verified_on and from the date the row was added.

Five equally weighted criteria

Each criterion receives 0, 0.5, or 1 point. The rating is their sum, from 0.0 to 5.0, displayed to one decimal. Half-point steps avoid suggesting fine precision that this editorial review cannot support. Missing evidence earns no points for that criterion; it does not prove that the underlying resource is poor.

Criterion0 points0.5 points1 point
R: relevanceNo established relation to the library's purposeA plausible but unreviewed lead or adjacent topicA direct skill, agent-workflow, evaluation, or governance use case
A: actionabilityNo reviewed guidance or usable descriptionOrientation, a feature list, discovery aid, or a bounded discussionConcrete procedures, technical constraints, examples, or a reusable decision method
P: source traceabilityNo identifiable sourceSecondary discovery index, shared conversation, or sources limited to related readingIdentifiable originating document/repository, or a guide tracing substantive claims to named sources
V: verification supportNo recorded way to assess claims or outcomesDiagnostic concepts or a limited check, with no complete evaluation method in the assessed materialExplicit tests, validation rules, reproducible evaluation steps, or scoped findings with their limits
B: boundaries and limitationsScope or limits are absent/unreviewedIntended scope is clear but limitations are lightly developedExplicit compatibility, uncertainty, failure, data/action, or adoption boundaries

Publisher identity, stars, installs, price, publication age, featured, and existing scores do not add points. A third-party index can be useful for discovery while earning fewer traceability or verification points than a source-linked procedure. Internal guides receive the same criteria as external resources; being authored by this library adds no points.

How to interpret and change a rating

Scores of 4.5–5.0 indicate strong documented usefulness across most criteria. Scores of 3.0–4.0 indicate a useful resource with specific evidence or scope gaps. Scores below 3.0 indicate a limited lead or sparse assessed information. These are descriptions of the information assessed, not quality certifications. An unreviewed draft can score 1.0 from its plausible topic and identifiable link only and remain hidden. A rating does not publish a draft or imply that its contents were reviewed.

The new rubric replaces the previous unexplained values, including existing nonblank scores. The original October 10, 2026 snapshot linked above contained 15 blank ratings. Current distribution: 5.0: 25; 4.5: 22; 4.0: 10; 3.5: 1; 3.0: 7; 2.5: 2; 1.0: 4. All 71 rows now have a documented score.

To change a score, edit the five criterion values, rationale, evidence references, and catalog fingerprint in resource-ratings.json, then run npm run ratings:sync. Use npm run ratings:check to reject missing or duplicate assessments, invalid points, stale catalog metadata, a CSV score that differs from its assessment, or Markdown that differs from the ledger. Reassess a title, URL, or summary change rather than copying the old rating forward. New IDs require their own assessment, including drafts. Review the underlying guide and update its dated evidence before treating a changed external claim as verified. The script reproduces the arithmetic and publication files; editorial judgment remains explicit in the ledger.

Per-resource assessment ledger

R, A, P, V, and B use the criteria above. Every row uses its recorded catalog description. Additional evidence links point to the exact existing repository snapshot used for this pass. Catalog targets are listed in the CSV and are not fresh source-review receipts.

Resource IDRatingRAPVBBasisRationale and additional evidence
avoid-ai-writing4.51110.51catalog-and-guideConcrete detect/rewrite modes and style-versus-authorship limits; the existing comparison adds scoped review context, not demonstrated writing effectiveness. Evidence: guide 1.
aura-skills3.010.5100.5catalog-onlyIdentifiable design-skills catalog with a clear workflow niche; the description supplies no outcome checks or assessed package evidence.
ming-design-layer-and-editable-design5.011111catalog-and-guideSource-linked output choices, editability checks, exact-artifact findings, and explicit execution/data limits form a complete decision guide. Evidence: guide 1.
ling-ui-design4.510.5111catalog-and-guideThe reconstruction use case is clear and the existing guide supplies scoped findings and checks; unresolved endpoint and write risks limit adoption readiness despite the useful evidence. Evidence: guide 1.
image-to-editable-ppt4.510.5111catalog-and-guideThe editable-slide use case has exact-artifact findings and output checks; documented upload and export risks remain unresolved and this score does not authorize execution. Evidence: guide 1.
agent-skills-overview4.01110.50.5catalog-onlyA direct format introduction with concrete package concepts; the catalog records limited evaluation detail and few explicit caveats.
agent-skills-specification5.011111catalog-onlyRequired structure, frontmatter constraints, file references, and validation provide a traceable technical contract and observable checks.

openai-build-skills5.011111catalog-onlyFocused workflow boundaries, supporting resources, dependencies, and representative tests make the recorded authoring guidance directly usable and checkable.
openai-record-replay4.01110.50.5catalog-onlyA concrete record-and-draft workflow tied to a stable Mac demonstration; the catalog does not specify a full acceptance test or wider compatibility limits.
anthropic-what-are-skills3.010.5100.5catalog-onlyA traceable plain-language introduction; the recorded scope is conceptual rather than procedural or evaluative.
anthropic-complete-guide-building-skills4.511110.5catalog-onlyThe catalog describes an end-to-end authoring, testing, and troubleshooting method; product and operational limits are less explicit in the assessed description.
oreilly-skills-context-window4.01110.50.5catalog-onlyAn attributed chapter explains package design and progressive disclosure; the recorded description provides fewer concrete tests and caveats.
openai-skills-concepts4.51110.51catalog-onlyA clear division between procedural guidance and MCP-controlled live data/actions; the catalog supplies conceptual verification rather than a complete test method.
troubleshoot-validate-structure5.011111catalog-onlyA specific validator-first diagnostic with named failure classes and a clear distinction between structural validity and runtime behavior.
troubleshoot-triggering5.011111catalog-onlyPositive and negative trigger cases create observable checks, and specificity/breadth warnings bound the recommended edit.
anthropic-use-skills4.01110.50.5catalog-onlyAn identifiable troubleshooting checklist for enablement and selection; outcome checks and environmental limits are only partly described.
troubleshoot-loading5.011111catalog-onlyConcrete enablement and package checks, valid-frontmatter requirements, and product-dependent loading paths support bounded diagnosis.

hamel-evals-skills4.511110.5catalog-onlyNamed evaluation workflows include failure analysis, judge validation, RAG checks, and human review; operational boundaries are less explicit in this article's catalog record.
aws-skill-equipped-agent-evaluation5.011111catalog-onlyA concrete trajectory/production-trace evaluation method distinguishes selection from instruction following and names its runtime/tool context.
skill2env-nvidia5.011111catalog-onlyPublic tasks, outcome tests, a skill-derived rubric, and a bounded model/training result provide checkable research claims with a defined experimental scope.
obra-superpowers4.51110.51catalog-and-guideComposable development procedures have a specific workflow scope; the existing guide provides review limits, while effectiveness is not established by the security review. Evidence: guide 1.
mattpocock-skills4.51110.51catalog-and-guideModular engineering procedures and selective-adoption boundaries are useful; scoped security review is distinct from measured productivity or correctness. Evidence: guide 1.
openspace3.010.5100.5catalog-onlyAn identifiable platform and local/cloud scope; the recorded feature list supplies neither an outcome evaluation nor detailed limitations.
vercel-skills-cli4.01110.50.5catalog-onlyConcrete skill lifecycle commands and named supported agents are useful; the catalog provides limited outcome and operational-boundary detail.
skills-rest2.510.50.500.5catalog-onlyDomain/origin/setup filters support discovery; a third-party index alone supplies limited primary-source traceability or verification support.
aisa-skills3.010.50.501catalog-onlyAn API-backed discovery catalog with explicit authentication/endpoint/permission caveats; the assessed description contains no concrete outcome checks.
elite-ai-tools2.510.50.500.5catalog-onlyKeyword discovery and repository links are useful leads; indexing public repositories does not itself evaluate their contents or outcomes.
agent-framework-python-skills4.51110.51catalog-onlyAn attributed release description records progressive disclosure and script/approval controls; the production-ready claim is a publisher statement, not a reproduced result.
nvidia-scan-agent-skills5.011111catalog-onlyThe recorded scanning method covers static/semantic checks, named risk classes, and release-gate triage; this score describes guidance, not scanner accuracy.
skillspector-enterprise-training5.011111catalog-and-guideAn explicit static/semantic review sequence, coverage interpretation, evidence outputs, and human-governed release decision are documented. Evidence: guide 1.
skillspector-skill-demo5.011111catalog-and-guideThe annotated skill exposes triggers, ordered steps, verification/update requirements, and explicit authorization boundaries with named references. Evidence: guide 1.
skillspector-skill-demo-v25.011111catalog-and-guideDistinct registry/static/semantic evidence layers and precise completeness/authorization rules provide a traceable review procedure. Evidence: guide 1.
vercel-skills-sh-security-check5.011111catalog-and-guideThe guide specifies canonical identity resolution, three-provider evidence collection, coverage limits, and inspection without target installation. Evidence: guide 1.
cisco-skill-scanner4.51110.51catalog-onlyNamed scanner layers and optional review support a concrete risk workflow; the catalog records human-judgment limits but no reproduced detection benchmark.
sage-agent-security4.010.510.51catalog-onlyTool-call allow/ask/deny behavior and local/optional-check boundaries are clear; the recorded architecture supplies fewer operational steps or measured checks.
clawhub4.0110.50.51catalog-onlyLifecycle operations and review-before-install boundaries aid discovery; registry-level verification signals do not establish every listed bundle's provenance or runtime safety.
so-you-found-a-skill-checklist5.011111catalog-and-guideThe source-linked checklist spans full-artifact inspection, dependencies, permissions, reliability, updates, and rollback decisions. Evidence: guide 1.
skills-in-the-agentic-performance-system5.011111catalog-and-guideA source-linked system framework connects failure diagnosis, controlled evaluation, configured tools/data, and governance to explicit outcomes. Evidence: guide 1.
agentic-performance-source-library4.510.5111catalog-and-guideAn annotated source map distinguishes evidence types and limits; its main function is reading and investigation rather than a complete operational procedure. Evidence: guide 1.
when-not-to-use-a-skill5.011111catalog-and-guideNamed sources, a concrete decision test, observable-verification questions, and trust-boundary constraints make adoption choices explicit. Evidence: guide 1.
enterprise-agent-skills-presenter-readiness4.5110.511catalog-and-guideDetailed role-based questions, rehearsal checks, and uncertainty/governance limits aid preparation; cited further reading is mainly other library guides. Evidence: guide 1.
academic-research-skills3.010.5100.5catalog-onlyAn identifiable collection and review-first lead; the sparse recorded description lacks concrete research procedures or evaluation evidence, and exclusion remains unchanged.
superpowers-evaluation-dialogue3.010.50.501catalog-onlyAn attributed discussion frames evaluation questions and explicitly disclaims primary evidence; it does not provide a recorded validated outcome.
theo-skills-code-video1.00.500.500catalog-onlyA plausible skills/code lead with an identifiable video URL; title, transcript, and summary remain unreviewed. The draft stays hidden.
skills-video-long1.00.500.500catalog-onlyA plausible skills lead and video URL only; content review and source summary are pending. The draft stays hidden.
skills-video-short1.00.500.500catalog-onlyA plausible skills lead and video URL only; content review and source summary are pending. The draft stays hidden.
gemini-skills-share1.00.500.500catalog-onlyA plausible shared-conversation lead; content and primary-source summary remain unreviewed. The draft stays hidden.
ai-evals-short-guide5.011111catalog-and-guideConcrete human-trace-to-evaluation steps, pinned nine-skill evidence, and explicit coverage/runtime limits support a bounded starting workflow. Evidence: guide 1.
skillselion3.510.50.50.51catalog-and-guideDiscovery rankings have documented denominators and third-party-signal limits in the existing guide; popularity and passed-through verdicts do not establish version-level safety. Evidence: guide 1.
skill-security-over-time5.011111catalog-and-guideA dated source-linked lifecycle method includes exact-version receipts, update triggers, scoped review coverage, quarantine, and rollback limits. Evidence: guide 1.
