Conciseness

The body is dense and assumes competence with no concept padding, but guidance to read '../../references/design/front-component-ui.md' is repeated three times (Front Component Defaults, Develop References, Handoffs) and the payload-shape paragraph could be tightened.

Actionability

Commands are fully executable and copy-paste ready ('command -v twenty && twenty app add object --name invoice --name-plural invoices --create-view --create-navigation-menu-item --create-page-layout --no-input', 'yarn twenty dev:typecheck', 'yarn lint', 'yarn twenty apply') plus concrete file-path conventions and a specific default payload shape covering the common cases.

Workflow Clarity

A clear sequence runs from setup verification through planning, code organization, entity creation, and a single end-of-work typecheck/lint/apply pass, with explicit failure handling ('If either file is missing, do not edit blindly', 'switch to manage-app'); however, there is no explicit fix-and-re-run loop if typecheck or lint fail, so a minor validation gap remains.

Progressive Disclosure

The body is a lean overview that defers all detail to clearly signaled one-level-deep references organized by topic, with an explicit navigation rule ('Read the smallest reference that matches the requested entity work') and per-reference scope descriptions; no nesting and no inlined bulk content. (No bundle files exist in this review directory to verify, but the structure as written matches the top anchor.)

Specificity

The description names the domain and enumerates four concrete entity types ('objects, layouts, logic functions, and front components'), but omits roles/permissions, workflows, and standalone pages that the skill body covers, so coverage has minor gaps rather than being comprehensive.

Completeness

Both what ('add or modify Twenty app entities...') and when ('Use when the user wants to...') are explicit, but the when-clause simply restates the what rather than offering separate concrete trigger phrases, matching the anchor where 'when' could be more explicit.

Trigger Term Quality

Natural terms like 'add or modify', 'objects', 'layouts', 'logic functions', and 'front components' are present, but common user phrasings such as 'custom fields', 'workflows', 'permissions', and 'pages' are missing, falling short of the comprehensive synonym coverage of the top anchor.

Distinctiveness Conflict Risk

'Twenty app' is a clear niche and 'inside an existing Twenty app' scopes away scaffolding, but closely related sibling skills (create-app, manage-app) are not disambiguated in the description, leaving minor overlap risk.
