Quality

Content

100%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.

The body is an exemplary instruction skill: lean and project-specific with zero padding, fully executable commands and code patterns, a clearly sequenced five-phase workflow with explicit validation checkpoints and error-recovery loops, and bulk detail appropriately delegated to five clearly signaled, one-level-deep reference files. No dimension shows a meaningful weakness.

DimensionReasoningScore

Conciseness

The body is dense and imperative, assumes competence (no explanations of zod, drizzle, transactions, or hooks), and every rule is non-obvious project-specific knowledge (e.g., 'Plain `pnpm doctor` runs pnpm's own command and exits 0', the 6,000-character AGENTS.md cutoff). Nothing is padded, matching anchor 5 rather than 4.

5 / 5

Actionability

Fully executable guidance throughout: copy-paste commands ('pnpm exec agent-native dev', 'pnpm action <name> --key value'), concrete code patterns ('export * from "@agent-native/toolkit/ui/dialog";', 'fail(message, { errorCode, statusCode })' with 409/404/403 mapping, 'toast.error(actionErrorMessage(error) ?? "<fallback>")'), and exact file paths. Matches anchor 5's copy-paste-ready coverage of common cases.

5 / 5

Workflow Clarity

Five clearly sequenced phases (Orient, Decide, Build, Verify, Report) with six numbered up-front decisions and an explicit ordered verification sequence including feedback loops ('Fix every finding, then rerun only what failed', guarded write called twice, browser smoke asserting the rejection toast). Destructive database operations are guarded (additive migrations, 'Never edit an applied entry'), so the workflow-clarity cap does not apply; this matches anchor 5.

5 / 5

Progressive Disclosure

The body holds the decisions and core workflow while bulk detail is split across five real, one-level-deep reference files (edit-points-chat/default selected by scaffold template, data-and-access, rooms-example, verification), each clearly signaled by path and verified to exist with no nested references. This matches anchor 5's well-signaled, appropriately split structure.

Description

86%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.

The description cleanly answers both what and when: a fast end-to-end workflow for turning the Agent-Native starter into a working domain app, triggered by explicit build/make/create/prototype phrasing covering the common request nouns. It is concise, third-person, and free of fluff; the only weakness is that the what-clause names a single workflow action rather than enumerating several concrete capabilities.

DimensionReasoningScore

Specificity

The what-clause ('turning this starter into a working domain app from a short or vague request') names the domain and one concrete action, but does not enumerate several distinct capabilities. It fits anchor 3 rather than 4 because the verb list (build, make, create, prototype) serves as trigger phrasing, not a list of what the skill does.

3 / 5

Completeness

It explicitly answers what ('Fast end-to-end workflow for turning this starter into a working domain app') and when ('Use when asked to build, make, create, or prototype...'), with concrete trigger phrases plus 'Read before the first edit' as additional trigger guidance. This matches anchor 5 exactly; anchor 4's weaker 'when' does not apply.

5 / 5

Trigger Term Quality

'build, make, create, or prototype an app, tool, tracker, dashboard, booking, inventory, or CRM system' comprehensively covers the natural verbs and object nouns users say when requesting this work, with synonyms. No meaningful natural terms are missing for this domain, so it matches anchor 5 rather than 4.

5 / 5

Distinctiveness Conflict Risk

'this starter' and 'with Agent-Native' scope it to a clear niche, but generic trigger nouns like 'tool' and 'dashboard' create minor overlap risk with closely related skills (e.g., charting or feature-addition skills). This places it at anchor 4 rather than 5's 'minimal conflict risk'.
