Conciseness

The body is mostly tight command reference, but it opens with unnecessary context Claude already knows ('DC Bank is a financial institution's online banking platform. Customers use it to manage their accounts...') and includes padded prose ('so you can focus on the integration logic rather than auth plumbing') plus an uninformative Overview bullet list. This matches anchor 3 (mostly efficient, some unnecessary explanation) more than 4.

Actionability

It provides concrete, copy-pasteable commands for every stage — install, login, connection ensure, polling, action list/run, and proxy — with a flags table. It sits at 4 rather than 5 because placeholders (CONNECTION_ID, actionId) are never shown resolved in a fully worked end-to-end example with sample output.

Workflow Clarity

There is a clear install→authenticate→connect→search→run sequence with state-checkpoint polling for connections, but the destructive/batch cap applies: running bank actions and proxy requests lack validation/verification steps, and the 'skip to Step 2' reference points to a step that is never labeled. This fits anchor 3 (steps listed, validation gaps) rather than 4.

Progressive Disclosure

As a single-file skill with no bundle directories, it is organized into clear sections (Install, Authentication, Connecting, Searching, Running actions, Proxy, Best practices) with no nested references. It earns 4 (good structure, minor organization gaps) rather than 5, which requires well-signaled one-level-deep external references that are absent here.

Specificity

The description names the domain ('DC Bank integration') but the actions — 'Manage data, records, and automate workflows' — are generic and abstract rather than concrete capabilities like viewing accounts or making transactions. It fits anchor 2 (domain named, actions minimal/generic) better than 3, whose example names a concrete operation.

Completeness

Both 'what' ('Manage data, records, and automate workflows') and 'when' ('Use when the user wants to interact with DC Bank data') are present, with an explicit trigger clause that lifts it above the 3 cap. It lands at 4 rather than 5 because the 'what' is generic where anchor 5 expects concrete trigger phrases.

Trigger Term Quality

It includes relevant keywords ('DC Bank', 'data', 'records', 'interact with DC Bank data') but misses common variations a user would naturally say such as 'accounts', 'transactions', 'balances', or 'banking'. This matches anchor 3 (some relevant keywords, missing common synonyms) rather than 4's fuller coverage.

Distinctiveness Conflict Risk

Naming a specific institution ('DC Bank') gives it a clear niche with minimal conflict risk, but the generic action verbs ('manage data', 'records', 'workflows') could overlap with other data-management skills. This fits anchor 4 (mostly distinct, minor overlap) rather than 5's fully distinct triggers.
