Quality

Content

27%

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

This skill provides a reasonable high-level outline for Angular typed reactive forms but critically lacks any inline code examples, making it non-actionable on its own. The repeated references to a non-existent bundle file mean the skill cannot deliver on its promises. The anti-patterns section is largely redundant with the main content.

Suggestions

Add at least one complete, executable code example inline showing a typed FormGroup<T> definition with controls and a custom validator function — don't rely solely on external references.

Include the referenced 'references/typed-forms.md' file in the bundle, or inline its key content, so the skill is self-contained and references resolve.

Remove the anti-patterns section or condense it into a single bullet list, since it mostly restates the positive guidance already given.

Add a brief concrete example of `fb.nonNullable.group(...)` usage to make section 3 actionable rather than descriptive.

DimensionReasoningScore

Conciseness

Mostly efficient but has some unnecessary filler like the priority label and phrases like 'This ensures form values always strings — avoids null in form values' which are somewhat redundant. The anti-patterns section largely restates what was already said in the main sections.

2 / 3

Actionability

No concrete code examples are provided inline — all executable guidance is deferred to a reference file that doesn't exist in the bundle. The instructions describe what to do ('use fb.nonNullable.group(...)') but never show a complete, copy-paste-ready example of a typed FormGroup, validator, or form setup.

1 / 3

Workflow Clarity

The skill outlines a reasonable sequence (define typed forms → extract validators → ensure nonNullable), but there are no validation checkpoints or feedback loops. For a relatively simple instructional skill this is acceptable, but the lack of any concrete workflow steps or verification guidance prevents a score of 3.

2 / 3

Progressive Disclosure

The skill references 'references/typed-forms.md' multiple times, but no bundle files are provided, meaning the referenced content doesn't exist. This creates a broken reference chain where the actual actionable content is entirely absent, making the skill incomplete.

Description

100%

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

This is a strong skill description that clearly identifies its niche within Angular typed reactive forms. It lists specific concrete capabilities, includes natural developer-facing trigger terms, and provides an explicit 'Use when' clause. The description is concise, uses third person voice, and would be easily distinguishable from other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'Build typed reactive forms', 'strict FormGroup typing', 'custom validators', and 'nonNullable controls'. These are concrete, well-defined Angular concepts.

3 / 3

Completeness

Clearly answers both 'what' (build typed reactive forms with strict FormGroup typing, custom validators, nonNullable controls) and 'when' (explicit 'Use when implementing typed reactive forms, custom validators, or form control patterns').

3 / 3

Trigger Term Quality

Includes strong natural keywords that Angular developers would use: 'typed reactive forms', 'FormGroup', 'custom validators', 'nonNullable controls', 'form control patterns'. These are terms developers naturally use when seeking help with Angular forms.

3 / 3

Distinctiveness Conflict Risk

Highly specific to Angular's typed reactive forms ecosystem with distinct triggers like 'FormGroup typing', 'nonNullable controls', and 'reactive forms'. Unlikely to conflict with general form-building or other framework skills.
