Quality

Content

50%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.

The body is a well-organized, concise overview that correctly pushes detail to separate guide files, but the referenced guides are missing from the bundle, leaving the skill with almost no actionable content. What remains is directional rules and a procedure without validation checkpoints, plus a filler 'When to Use' sentence.

Suggestions

Ship the five referenced guide files in the bundle (e.g., under references/) or remove the links and inline the most critical rules (naming standards, Result-type error handling, a DynamicData pipeline example).

Add at least one small executable code example in the body (e.g., a ViewModel using a Result type and a DynamicData operator) so the core conventions are concrete, not just named.

Replace the vacuous 'When to Use' sentence with concrete applicability conditions (e.g., 'Use when creating or editing Avalonia Views, ViewModels, or Zafiro/DynamicData pipelines.') and add a validation checkpoint to the procedure (e.g., 'Confirm the searched helper exists before proposing a new extension method').

DimensionReasoningScore

Conciseness

The body is lean: the four Core Pillars and the three-step procedure state rules without over-explaining concepts Claude already knows (no 'what is MVVM' padding). One instance keeps it from 5: the 'When to Use' section is a vacuous filler sentence ('This skill is applicable to execute the workflow or actions described in the overview') that adds no information and should be trimmed or made concrete.

4 / 5

Actionability

The guidance is high-level direction only — 'Search First', 'propose a new reusable extension method', 'Ensure DynamicData operators are used instead of plain Rx' — with no code, commands, naming examples, or concrete patterns in the body. This matches anchor 2 ('high-level hints but missing the specific steps to execute') rather than 3, because even the instruction-level specifics (e.g., a Result-type usage example or a naming rule) are absent from the bundle.

2 / 5

Workflow Clarity

'Procedure Before Writing Code' provides a coherent 3-step sequence, but there are no validation checkpoints or feedback loops (e.g., how to confirm a Zafiro helper actually exists before writing a new extension). This fits anchor 3 ('Steps listed but validation gaps; sequence present but checkpoints missing or implicit').

3 / 5

Progressive Disclosure

The body promises an ideal structure — five clearly labeled one-level-deep guide links with short descriptions — but none of the five referenced files (core-technical-skills.md, naming-standards.md, avalonia-reactive-rules.md, zafiro-shortcuts.md, patterns.md) exist in the bundle (no references/ directory at all). Scoring against the actual bundle structure, navigation is broken, capping this at 3 rather than 5.

Description

52%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.

The description is distinctive and names its niche clearly, but it is generic about what the skill actually does and provides no 'when to use' trigger guidance. Adding one or two concrete capabilities and a Use-when clause would lift it substantially. It is correctly written in third person with no fluff.

Suggestions

Replace the generic 'Mandatory skills, conventions, and behavioral rules' with 1-2 concrete capabilities, e.g., 'Enforce Result-based error handling, DynamicData pipelines, and platform-independent ViewModels in Avalonia apps.'

Add an explicit trigger clause, e.g., 'Use when writing or modifying Avalonia UI code, ViewModels, or Zafiro/DynamicData pipelines.'

Include natural variations users would say (MVVM, .axaml, ReactiveUI, cross-platform C#) to improve trigger term coverage.

DimensionReasoningScore

Specificity

The description names the domain ('Avalonia UI development using the Zafiro toolkit') but the stated actions — 'Mandatory skills, conventions, and behavioral rules' — are generic with no concrete capability listed. This matches anchor 2 ('Names the domain but actions are minimal or generic'), not 3, since no specific action like a concrete convention or operation is stated.

2 / 5

Completeness

The 'what' is present (conventions and behavioral rules for Avalonia/Zafiro development) but there is no 'Use when...' clause or equivalent trigger guidance; the judging guidelines explicitly cap completeness at 3 in that case. Not 2, because the 'what' is clear enough rather than vague.

3 / 5

Trigger Term Quality

'Avalonia UI' and 'Zafiro toolkit' are natural terms a user of this stack would say, but common variations and synonyms are absent (e.g., .axaml, MVVM, C#, cross-platform, ReactiveUI). Fits anchor 3 ('Some relevant keywords but missing common variations or synonyms') rather than 4, which requires good coverage with only a few gaps.

3 / 5

Distinctiveness Conflict Risk

'Avalonia UI' + 'Zafiro toolkit' defines a clear niche with distinct triggers and minimal overlap with other skills, matching anchor 5 exactly. Users of this stack would naturally name these technologies, so it is unlikely to trigger the wrong skill.
