Quality

Content

67%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 delivers a concrete, executable Membrane-based workflow for Amazon Polly with genuine state-handling and a feedback loop for user authentication. Weaknesses are moderate: conceptual/marketing padding up front, a "Step 2" reference that points nowhere, inconsistent membrane vs npx invocation, and a redundant Popular actions section.

Suggestions

Delete or compress the opening paragraphs explaining what Amazon Polly is and who uses it — Claude already knows this — and trim marketing prose like "This is the fastest way to get a connection."

Fix the dangling "Skip to Step 2" references by naming or numbering the target sections, and pick one invocation form (membrane vs npx @membranehq/cli@latest) consistently.

Merge the one-line "Popular actions" section into "Searching for actions" to remove the duplicated action-list instruction.

DimensionReasoningScore

Conciseness

The intro paragraph ("cloud-based service that turns text into lifelike speech. Developers use it to create applications that talk...") explains a service Claude already knows, and phrases like "This is the fastest way to get a connection. The URL is normalized to a domain..." are padded marketing prose. Otherwise mostly efficient commands, matching anchor 3; not 4 due to the dedicated conceptual/marketing passages.

3 / 5

Actionability

Concrete executable commands throughout (install, login, connection ensure, --wait polling, action run with --input, proxy flag table). Minor gaps: "skip to Step 2" references a step that is never defined, and invocation alternates between "membrane" and "npx @membranehq/cli@latest". Matches anchor 4 (mostly executable with minor gaps); not 5 because of the dangling references and inconsistent invocation.

4 / 5

Workflow Clarity

A clear install → login → connect → poll-state → discover → run sequence with a real feedback loop on CLIENT_ACTION_REQUIRED (re-poll after the user authenticates in the browser). The undefined "Step 2" reference and the membrane/npx inconsistency leave minor validation/navigation gaps, matching anchor 4; not 5 because those gaps break the otherwise strong sequence.

4 / 5

Progressive Disclosure

A single self-contained file with clear section headers and one external docs link; no bundle files to navigate. Minor organization gaps: the "Popular actions" section is a one-line duplicate of "Searching for actions", and the proxy options table is inline (acceptable at this size but redundant with the duplicated discovery instructions). Matches anchor 4; not 5 due to the duplicated/under-filled sections.

Description

45%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 names the service and includes a Use-when clause, but the capability statement is template filler that omits every actual Polly capability and every natural trigger term. A user asking to "convert text to speech" or "generate audio narration" would not naturally trigger it.

Suggestions

Replace "Manage data, records, and automate workflows" with the actual capabilities documented in the body, e.g. "Synthesize speech from text or SSML, list and describe available voices, and send raw Polly API requests via Membrane."

Add natural trigger terms and synonyms: "text-to-speech", "speech synthesis", "convert text to audio/voice/narration", "Polly voices".

Make the when-clause specific: "Use when the user wants to turn text into speech, generate voice narration, or list/compare Amazon Polly voices."

DimensionReasoningScore

Specificity

"Manage data, records, and automate workflows" is generic boilerplate; no concrete capability (synthesize speech, list voices, describe voices) is named, even though the body documents them. Anchor 2 ("Names the domain but actions are minimal or generic") fits; not 3 because the description lists zero concrete actions.

2 / 5

Completeness

The "when" is present ("Use when the user wants to interact with Amazon Polly data") but the "what" ("Manage data, records, and automate workflows") is too vague to convey what the skill actually does (text-to-speech). Falls between anchor 3 and 4; the weak "what" holds it at 3.

3 / 5

Trigger Term Quality

"Amazon Polly" is a relevant keyword users would say, but every natural phrase ("text-to-speech", "speech synthesis", "convert text to audio", "voices") is missing, and "data", "records", "workflows" are generic filler. Matches anchor 3 (relevant keywords present, common variations/synonyms missing); not 4 because coverage beyond the product name is absent.

3 / 5

Distinctiveness Conflict Risk

"Amazon Polly" anchors a niche, but "Manage data, records, and automate workflows" is template boilerplate shared by any app-integration skill, so a request to "manage records" could match many skills. Matches anchor 3 ("somewhat specific but could still overlap with similar skills").
