implementing-al-interfaces

Defines AL interfaces and interface patterns with implementing codeunits, creates extensible enums to switch providers, and enables dependency injection for unit testing AL code with mocks. Use when building plugin architectures, adding loose coupling, replacing conditional logic with polymorphism, or creating Business Central extensions with swappable implementations.

Quality

Content

85%Weight 40%Scale 1-5

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

A well-structured AL interface skill with a clear sequenced procedure, explicit validation gates, and a real one-level reference file holding complete examples. The main weakness is templated (placeholder) code in the body rather than directly executable examples.

Suggestions

Inline one complete, concrete (non-placeholder) example alongside the templated one so the body is immediately actionable without opening the reference.

Consolidate the single reference pointer so interface-patterns.md is signaled in one place, removing the duplicate mention.

Fold the 'Validation Gates' checkpoints directly into their corresponding procedure steps so each step carries its own validation checkpoint inline.

Dimension	Reasoning	Score
Conciseness	Mostly lean code-first content that assumes Claude's AL knowledge without explaining basic concepts, but the reference to interface-patterns.md is repeated in two places and the standalone 'Validation Gates' section slightly duplicates step context.	4 / 5
Actionability	Provides concrete AL code blocks for each step plus a placeholder substitution table, but the main-body examples use templated placeholders rather than copy-paste-ready code; the referenced file supplies fully concrete examples.	4 / 5
Workflow Clarity	A clearly sequenced 4-step procedure is paired with explicit 'Validation Gates' checkpoints ('After Step 2', 'After Step 3', 'Final') and a stated feedback loop ('Fix signature -> Re-compile -> Verify method calls work polymorphically').	5 / 5
Progressive Disclosure	Well-organized sections with a single one-level-deep reference to the verified references/interface-patterns.md, clearly signaled both inline and in a References section, keeping the overview lightweight.	5 / 5

Description

92%Weight 40%Scale 1-5

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, third-person description that names concrete capabilities and pairs them with an explicit 'Use when...' clause covering several natural trigger scenarios. The only minor gap is slightly less synonym coverage in trigger terms.

Dimension	Reasoning	Score
Specificity	Lists multiple distinct concrete actions — 'Defines AL interfaces', 'creates extensible enums to switch providers', 'enables dependency injection for unit testing' — giving comprehensive coverage rather than a single generic action.	5 / 5
Completeness	Explicitly answers both what it does ('Defines AL interfaces...') and when to use it ('Use when building plugin architectures, adding loose coupling...') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Strong natural phrases users would say ('plugin architectures', 'loose coupling', 'polymorphism', 'Business Central extensions', 'swappable implementations') but lacks some synonyms/variations a user might voice, keeping it just below comprehensive.	4 / 5
Distinctiveness Conflict Risk	Targets a clear AL/Business Central niche ('Business Central extensions with swappable implementations') with distinct triggers, minimizing overlap with unrelated skills.	5 / 5
	Total	19 / 20 Passed
