Conciseness

Deliberately telegraphic style with zero explanation of concepts Claude already knows — every line carries project-specific information. Minor inefficiencies remain: the 11-layer model appears twice (ASCII diagram plus the 'Files canon' table) and inline catalog listings (9 EBTs, 21 SectionKeys, 5 archetypes) duplicate references/offer-catalogs.md. Anchor 4 (efficient, minor trimming possible) fits better than anchor 5's every-token-earns-its-place.

Actionability

Fully executable throughout: exact file paths, a concrete Override(...) code block with field-by-field comments, copy-paste test commands ('cd backend && .venv/bin/pytest tests/architecture/ -x -q --tb=short'), a SQL data-check query, and the exact API endpoint. Matches the anchor-5 copy-paste-ready standard with common cases covered.

Workflow Clarity

Every business operation has a numbered SOP; destructive/batch operations get explicit validation gates ('Query SELECT COUNT(*) ... IS NOT NULL', 'Pregunta primero: ¿hay tenants en prod?', deprecation windows instead of hard drops), and a mandatory post-change test-gates block closes the loop. Matches anchor 5's explicit validation steps and error-recovery checkpoints.

Progressive Disclosure

Two real reference files (references/offer-catalogs.md, references/form-runtime-array.md) exist and are clearly signaled under 'Project invariants (read on demand)' with one-line descriptions, one level deep. However, sizable catalog detail that the references already cover is inlined in the body (EBT/archetype/section enumerations, layer tables). Anchor 4 (good structure, most content appropriately placed, minor organization gaps) fits better than anchor 5's fully appropriate split.

Specificity

Lists several concrete actions ('modificar/agregar/fusionar/eliminar offers, expertise, presets, secciones, fields') with broad domain coverage, but the verbs are generic and 'post-refactor field-contract-platform' is internal jargon rather than a capability. Fits anchor 4 (several specific actions, minor gaps) better than anchor 5's fully comprehensive distinct-action list.

Completeness

Explicitly answers both what ('Expert en arquitectura completa Offer Studio... Cubre fields/secciones/expertise/presets/relaciones/descripciones') and when ('Use cuando user pide modificar/agregar/fusionar/eliminar... o quiere entender cómo Nicolify maneja offers a cualquier nivel'), matching the anchor-5 example structure of concrete what + explicit when with trigger phrases.

Trigger Term Quality

An explicit 'Triggers:' list covers natural Spanish user phrases ('modificar oferta', 'agregar campo a oferta', 'sección nueva', 'qué le pregunto al cliente') plus English synonyms and jargon users would mix in ('lead magnet', 'upsell', 'downsell', 'archetype', 'ladder'). Comprehensive synonym coverage matches the anchor-5 example.

Distinctiveness Conflict Risk

The niche (Nicolify Offer Studio) and specific triggers make conflict with unrelated skills minimal, but 'cambiar preset' and the presets coverage overlap directly with the peer skill 'offer-type-preset-expert' that the body routes preset-only work to — a boundary the description does not draw. Anchor 4 (mostly distinct, minor overlap with a closely related skill) fits; not 5 because of that documented peer conflict.
