webiny-api-architect

The hub skill for all API/backend architecture in Webiny. Covers architecture overview, Services vs UseCases, feature naming and organization, feature structure templates, DI decision tree, anti-patterns, createFeature, createAbstraction, container registration, domain errors, entity patterns, naming conventions, scoping rules, and code conventions. Use this skill for ANY backend API work — it references sub-skills for deep implementation details.

Quality

Content

77%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-organized reference whose concrete code, tables, and checklist make it directly usable. It is held back by length/redundancy and by being a monolith rather than progressively disclosing detail into separate reference files as its own description implies.

Suggestions

Consolidate the three treatments of naming ("Feature Naming Philosophy", the naming anti-pattern in "Anti-Patterns", and the "Naming Conventions" table) into one authoritative section to cut redundancy.

Split deep implementation detail (ServiceProvider pattern, Entity/Value Object patterns, full domain-error and typed-union examples) into reference files under references/ and link to them one level deep, matching the description's claim that sub-skills hold the deep details.

Tighten the TL;DR to the handful of decisions a reader must make first (Service vs UseCase, feature naming, scoping) and let the detailed sections carry the rest, trimming restated rules across "Code Conventions", "Key Rules", and the checklist.

DimensionReasoningScore

Conciseness

Content is mostly concrete and non-fluffy, but at ~679 lines it is long and repeats itself — feature/technical naming is restated in "Feature Naming Philosophy", the naming anti-pattern, and the "Naming Conventions" table, and full ServiceProvider/entity implementations could live in sub-skills.

2 / 3

Actionability

Provides extensive executable TypeScript (abstractions, feature registration, domain errors, ServiceProvider), concrete decision tables ("DI Decision Tree", "Container Registration Methods", "Scoping Rules"), and copy-paste-ready directory templates.

3 / 3

Workflow Clarity

Gives explicit ordering rules ("Register the CMS model first", Feature.register vs container.register) and a verification "Checklist" of checkbox items for building a new API feature, which serves as the validation checkpoint for this pattern-based skill.

3 / 3

Progressive Disclosure

The body is well-sectioned (TL;DR + organized topics) but is a single monolithic document with no bundle files and no one-level-deep references; detailed pattern content that the description says lives in sub-skills is instead inlined here. The "Related Skills" list signals separate skills but not bundle references.

Description

85%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that states both the skill's scope and an explicit use-trigger, well-scoped to the Webiny backend niche. Its only weakness is limited natural-term variation and a jargon-dense capability list in the trigger dimension.

Suggestions

Soften the trigger surface with a couple of plain-user phrasings (e.g. "building or modifying a Webiny API extension", "adding a backend feature/service") alongside "ANY backend API work" to broaden natural-term coverage.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — "architecture overview, Services vs UseCases, feature Naming and organization, ... createFeature, createAbstraction, container registration, domain errors" — naming specific Webiny actions rather than vague language.

3 / 3

Completeness

Explicitly answers both what ("The hub skill for all API/backend architecture in Webiny. Covers ...") and when ("Use this skill for ANY backend API work — it references sub-skills for deep implementation details.").

3 / 3

Trigger Term Quality

The trigger clause "Use this skill for ANY backend API work" with "Webiny" and "backend API" are natural terms, but coverage of natural user phrasings is thin and the long capability list is jargon-heavy (createFeature, createAbstraction, DI decision tree).

2 / 3

Distinctiveness Conflict Risk

Clearly scoped to a distinct niche — "all API/backend architecture in Webiny" — making it unlikely to trigger for unrelated skills.
