Quality

Content

61%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 generally actionable, well-commanded skill whose connection setup workflow includes genuine state-checkpoint handling. Its main weaknesses are padding around the overview, a destructive/batch action catalog with no verification guidance, and internal references to a nonexistent "Step 2".

Suggestions

Add a validation step before destructive actions (delete-customer, cancel-subscription, refund-invoice, void-invoice), e.g. confirming the target ID with the user or re-fetching the record before and after running.

Fix the two "skip to **Step 2**" references by renaming the target section ("Searching for actions") to Step 2 or updating the pointers.

Trim the introductory paragraph and the bare "Chargebee Overview" bullet list, which explain things Claude already knows and add no actionable detail.

DimensionReasoningScore

Conciseness

The body is mostly efficient commands and tables, but includes unnecessary padding: the introductory paragraph "Chargebee is a subscription billing and revenue management platform. It helps SaaS and subscription-based businesses automate recurring billing...", the hollow "Chargebee Overview" bullet list (Customer/Subscription/Plan/Addon/Coupon with no explanations), and Membrane internals prose like "The URL is normalized to a domain and matched against known apps".

3 / 5

Actionability

Concrete, copy-paste-ready CLI commands throughout ("npm install -g @membranehq/cli@latest", "membrane connection ensure", "membrane action run ... --input '{\"key\": \"value\"}'"), with only minor gaps: "membrane login --tenant --clientName=<agentType>" never shows what value --tenant takes, and <actionId> is never shown being resolved from action list output. Not 5 because of these executable gaps; not 3 because everything given is runnable, not pseudocode.

4 / 5

Workflow Clarity

The connection workflow has a good state-based decision tree (READY / BUILDING / CLIENT_ACTION_REQUIRED / CONFIGURATION_ERROR with polling), but the text twice says "skip to **Step 2**" while no Step 2 heading exists, and the action catalog includes destructive operations (Delete Customer, Cancel Subscription, Refund Invoice, Void Invoice) with no validation/verification guidance — the rubric's destructive-operation cap of 3 applies.

3 / 5

Progressive Disclosure

Single-file skill (no bundle files present) with well-organized sections (Install, Authentication, Connecting, Searching, Running, Proxy, Best practices) and compact inline tables (Popular actions, proxy flags). Not 5 because the dangling "Step 2" references and the 20-row action catalog inlined in the main file are minor organization gaps; not 3 because nothing that clearly belongs in a separate file is buried.

Description

66%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 is distinct (a named app) and properly structured with an explicit "Use when" trigger, but it undersells the skill: it mentions only customer management while the body covers subscriptions, invoices, item prices, and refunds. Adding those actions and natural billing keywords would materially improve it.

Suggestions

Enumerate the main capabilities beyond customers, e.g. "Manage customers, subscriptions, invoices, and item prices in Chargebee".

Add natural trigger phrases and synonyms users would say — "billing", "subscription management", "invoices", "refunds" — to the "Use when" clause.

Keep third-person voice and brevity while expanding; avoid padded marketing phrasing.

DimensionReasoningScore

Specificity

"Chargebee integration. Manage Customers." names the domain plus exactly one concrete action — matching anchor 3 ("Names domain and 1-2 concrete actions"). Not 4 because the body covers many more actions (subscriptions, invoices, item prices, refunds) that the description never mentions.

3 / 5

Completeness

Both what ("Chargebee integration. Manage Customers.") and when ("Use when the user wants to interact with Chargebee data") are explicitly present, but the what lists only one action and the when is generic — anchor 4 ("'when' could be more explicit or specific"), not anchor 5's comprehensive actions with concrete trigger phrases.

4 / 5

Trigger Term Quality

Relevant keywords are present ("Chargebee", "Customers", "interact with Chargebee data") but common variations a user would naturally say — "billing", "subscriptions", "invoices", "payments" — are missing, matching anchor 3 rather than anchor 4's good coverage.

3 / 5

Distinctiveness Conflict Risk

"Chargebee" names a specific commercial app, giving a clear niche with distinct triggers and minimal conflict risk even against other billing/subscription skills — anchor 5.
