Quality

Content

86%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 tight, instruction-only browser-orchestration skill that is efficient and well-structured with strong concrete guidance. It would benefit from an explicit feedback loop and a concrete capture/create call example.

Suggestions

Add an explicit validate-then-fix-then-retry loop (e.g., after browser_create_credential, verify the credential is selectable; if it fails, re-inspect and retry) to lift workflow_clarity to 5 for this sensitive operation.

Include one short concrete example showing a browser_capture_secret call followed by a browser_create_credential call with matching credentialsKey, data, and resolveData fields.

Optionally surface the recommended_tools-backed default decision rule (when to web-search vs fetch-url) as a one-line checkpoint inside the procedure for faster routing.

DimensionReasoningScore

Conciseness

The body is lean and dense with no padding or over-explanation of concepts Claude already knows; every line (Secrets, Browser Discipline, Closeout) earns its place.

5 / 5

Actionability

Concrete tool calls with parameters are given throughout (e.g. browser_capture_secret with ref/redactedKey, data vs resolveData), but no single copy-paste-ready example of a capture-then-create sequence is shown, leaving a minor gap.

4 / 5

Workflow Clarity

The Default Procedure is a clear numbered sequence with explicit completion criteria and a closeout step, but there is no explicit validate-then-fix-then-retry feedback loop for the sensitive credential-creation operation.

4 / 5

Progressive Disclosure

At under ~60 lines with no external references needed, the content is split into four well-organized, clearly signaled sections, which meets the simple-skill exception for a top score.

Description

87%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 well-crafted description that clearly states what the skill does and gives explicit, natural trigger guidance for when to use it, with a distinct niche. Minor room to broaden trigger synonyms and enumerate more concrete actions.

DimensionReasoningScore

Specificity

"Guides n8n credential setup through Computer Use browser tools" names the domain plus a concrete action, and the trigger list enumerates specific credential types, but action coverage is not as comprehensive as the anchor-5 multi-action example.

4 / 5

Completeness

It explicitly answers both what ("Guides n8n credential setup through Computer Use browser tools") and when ("Use when a user needs OAuth apps, API keys, client IDs, client secrets...") with concrete trigger phrases, matching the anchor-5 example.

5 / 5

Trigger Term Quality

"OAuth apps, API keys, client IDs, client secrets, or other credential values" are natural terms users would say; a few synonyms (tokens, connection strings) and file extensions are absent, falling just short of anchor 5.

4 / 5

Distinctiveness Conflict Risk

The niche is tightly scoped to n8n credential setup via Computer Use browser tools with distinct credential-console triggers, giving minimal conflict risk with other skills.
