Conciseness

The body is lean and assumes Claude's competence — it does not explain what TypeORM, jsonb, or a syncable entity is, and each code block earns its place without padding, matching the 'lean and efficient' anchor.

Actionability

Every step ships an exact file path plus a concrete, copy-paste-ready TypeScript snippet (entity class, flat types, action types, constant registrations) rather than pseudocode or abstraction.

Workflow Clarity

A clearly sequenced six-step process with explicit validation in the checklist ('TypeScript compiles without errors') that gates progression to Step 2, plus a derivation-dependency graph for the trickiest step.

Progressive Disclosure

Content is appropriately scoped as Step 1/6 of a multi-skill chain, with well-organized sections and clear one-level navigation to the next step and the parent @creating-syncable-entity rule; no bundle files exist to reference, so the well-organized single-file structure scores 3 per the simple-skill guidance.

Specificity

Lists multiple concrete actions — 'define types, entities, and central constant registrations' and 'defining TypeORM entities, flat entity types, or registering in central constants' — matching the anchor that enumerates several specific actions.

Completeness

Explicitly answers both 'what' (define types, entities, central constant registrations for syncable entities) and 'when' via the explicit 'Use when creating new syncable entities, defining TypeORM entities...' clause.

Trigger Term Quality

Natural developer trigger phrases like 'creating new syncable entities', 'defining TypeORM entities', and 'flat entity types' cover the terms a Twenty contributor would actually say; the inline constant names add specificity rather than replacing natural language.

Distinctiveness Conflict Risk

The niche is tightly scoped to Twenty's workspace migration syncable entities and four named central constants, making it unlikely to trigger for unrelated skills.
