Quality

Content

88%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 highly actionable, well-sequenced skill body: every step has executable commands, explicit validation gates, and concrete error-recovery loops, with prompt-injection safeguards for untrusted discovery data. The main improvement areas are trimming the pagination spec and preamble restatement, and moving reference-shaped detail (scope lists, rendering rules) into a bundled reference file so the referenced paths exist alongside SKILL.md.

Suggestions

Trim restated guidance: the read-only preamble (no create/patch, no manual redirect URIs) repeats rules spelled out in Steps 3–4; state them once at the point of action to reduce token cost.

Move the permission scope inventory and the pagination/listing rendering rules into a reference file in the skill bundle (e.g., references/permissions.md), keeping SKILL.md as the workflow overview with a clearly signaled one-level-deep link.

The referenced ${PLUGIN_ROOT} scripts and shared-instructions.md are not present in the skill's own directory; bundle or mirror them under the skill so the referenced paths resolve relative to SKILL.md.

DimensionReasoningScore

Conciseness

The body is dense and command-first with almost no explanation of concepts Claude already knows, but the read-only preamble partially restates later detail and the pagination/listing spec (lines 108–159) runs long. Efficient overall with minor trimming opportunities, matching anchor 4 rather than the lean-every-token-earns-its-place anchor 5.

4 / 5

Actionability

Fully executable guidance throughout: copy-paste bash for app-root verification, environment/tenant resolution, script invocations, and JSON validation, plus exact prompt texts, exact AskUserQuestion choices, and a concrete example target shape. This matches the anchor for copy-paste ready commands covering common cases.

5 / 5

Workflow Clarity

A numbered 7-step workflow with an overview line, explicit gates (Step 1 root check, empty ENV_ID/TENANT_ID stops, Step 6 JSON validation), and multiple feedback loops (discovery-failure fallback prompt, permission-repair path that reruns Step 3, unrecognized-command reprint-and-reask). Not 4: validation and error recovery are explicit at nearly every stage, not mostly present.

5 / 5

Progressive Disclosure

Sections are clear and external references are well signaled and one level deep (shared-instructions.md marked "read first", named scripts in the commands). However the skill bundle contains only SKILL.md — no references/ or scripts/ files — so the ${PLUGIN_ROOT} references cannot be verified within the bundle, and reference-shaped detail (permission scope lists, pagination rendering rules) is fully inlined. Good structure with minor organization gaps matches anchor 4 rather than the well-split anchor 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 description: concrete, comprehensive action list combined with an explicit use-when trigger clause and a clearly distinct niche. The only weakness is modest synonym coverage (e.g., no "Azure AD" or "client ID" phrasing).

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "discover and verify available Entra ID app registrations", "wire one to a Power Apps Wrap mobile app", "create one through the Wrap page", "update auth.config.json" — covering the skill's full capability span. Coverage is comprehensive rather than having minor gaps, so it matches the top anchor.

5 / 5

Completeness

Explicitly answers both: the "what" via concrete actions (discover/verify/wire/create/update) and the "when" via the explicit "Use when the user wants to…" trigger clause with concrete trigger phrases. Not 4 because the "when" is fully explicit, not merely present.

5 / 5

Trigger Term Quality

Natural domain terms users of this flow would say ("Entra ID app registrations", "Power Apps Wrap", "auth.config.json") are present and well-chosen. Common synonyms such as "Azure AD" or "client ID" are missing, which keeps it below comprehensive coverage.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (wiring Wrap mobile-app auth to Entra ID registrations) with distinct technical triggers unlikely to fire for unrelated skills. Overlap risk with a generic skill is minimal.
