77%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, deeply actionable skill body with an explicitly sequenced workflow, real validation checkpoints, and clean one-level-deep progressive disclosure into verified bundle files. Its main weakness is conciseness: archetype and upstream-example guidance is duplicated across sections and references are listed both inline and in the References block.
Suggestions
Deduplicate the archetype guidance: keep the decision rubric in 'Classify The App Before Choosing Code' and have Build Workflow step 0 reference it instead of restating it.
Consolidate the upstream starting-point guidance: merge 'Default Starting-Point Order' and Build Workflow step 2a into one section to remove the overlapping rationale.
Trim the inline reference callouts or the References section so each path is announced once; consider adding at least one minimal executable code block (server resource registration or a widget bridge listener) to lift actionability to the top anchor.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Content is domain-specific rather than teaching known concepts, but it repeats guidance in two places each — archetype classification appears both in 'Classify The App Before Choosing Code' and 'Build Workflow step 0', and upstream-example selection appears both in 'Default Starting-Point Order' and 'step 2a' — and every reference is listed both inline and again in the References section, so it could be tightened noticeably. | 3 / 5 |
Actionability | Gives concrete, specific guidance — exact annotations (readOnlyHint, destructiveHint, openWorldHint, idempotentHint), the MIME type 'text/html;profile=mcp-app', exact _meta.ui fields (csp/domain/prefersBorder, connectDomains/resourceDomains), exact window.openai methods and globals, the /mcp endpoint, and 'ngrok http <port>' — but provides no full copy-paste code blocks for a server registration, tool handler, or widget bridge listener. | 4 / 5 |
Workflow Clarity | The Build Workflow is explicitly numbered 0–9 with dedicated validation steps (5a 'Minimum Working Repo Contract' checklist and 6 'Validate the Local Loop' ladder running low-cost checks before runtime checks), feedback-loop language for retries/idempotency, and an explicit 'say exactly what you did not run' instruction, satisfying the validation-checkpoint requirement. | 5 / 5 |
Progressive Disclosure | The body is an overview that signals one-level-deep references — each of the 7 reference files and the scaffold script is cited inline with a clear purpose statement ('Read references/X.md for...') and summarized in a References section; all referenced paths resolve to real bundle files, so navigation is easy and nothing is nested beyond one level. | 5 / 5 |
