Quality

Content

86%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 tight, highly actionable ruleset with excellent structure and no padding, leveraging project-specific context Claude would not already know. Its only soft spot is the absence of complete runnable code examples and explicit workflow validation checkpoints, though neither is strictly required for a rules-based skill.

DimensionReasoningScore

Conciseness

The body is lean and dense with no padding or explanation of concepts Claude already knows; the opening paragraph earns its place by stating project-specific CI context ('CI runs the test suite on Linux only') that is non-obvious, and every rule is stated once and tightly, matching the 'lean and efficient; every token earns its place' anchor.

5 / 5

Actionability

Guidance is concrete and executable, naming exact APIs (vibe.core.utils.platform is_windows(), resolve_windows_shell(), pathlib.Path) and a copy-paste-ready snippet (monkeypatch.setattr(module, "is_windows", lambda: True)), but it provides inline snippets rather than complete self-contained examples, fitting 'mostly executable guidance; concrete code with minor gaps'.

4 / 5

Workflow Clarity

Content is organized into clearly labeled sections (Code rules, Terminal data, Testing) with unambiguous, specific directives, but it is a ruleset rather than a sequenced multi-step process with explicit validation checkpoints, so it sits below the anchor requiring feedback loops and above the one with sequence gaps.

4 / 5

Progressive Disclosure

The body is under 50 lines with no need for external references and is organized into well-signaled sections, satisfying the simple-skill exception that allows a 5 with just well-organized sections; no nested or buried references exist.

Description

78%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 clearly and explicitly covers both what the skill does and when to use it, with strong trigger-term coverage and a well-scoped niche. Its only weakness is that the stated capability ('rules') is somewhat abstract while the concrete items live in the trigger clause.

DimensionReasoningScore

Specificity

The 'what' is stated abstractly as 'Cross-platform development rules', but the description lists several concrete domains (paths, Windows support, shell compatibility, terminal data streams, cross-OS testing) that read as trigger contexts rather than distinct concrete actions the skill performs, matching the 'names domain and 1-2 concrete actions' anchor rather than the comprehensive action-list anchor at 5.

3 / 5

Completeness

It explicitly answers 'what' ('Cross-platform development rules for Mistral Vibe') and 'when' with a concrete 'Use when writing platform-specific logic, handling paths, Windows support...' clause, matching the anchor that requires both what and when with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural developer terms appear ('Windows support', 'shell compatibility', 'handling paths', 'cross-OS testing strategies', 'platform-specific logic') with a synonym ('cross-OS' for 'cross-platform'), giving good coverage though a few common phrasings are absent, fitting the 'good keyword coverage; a few natural terms missing' anchor.

4 / 5

Distinctiveness Conflict Risk

The cross-platform niche for a named project (Mistral Vibe) with distinct triggers (Windows support, terminal data streams, shell compatibility) is mostly distinct with only minor overlap risk against general coding skills, fitting 'mostly distinct; minor overlap risk' rather than the fully-isolated anchor at 5.
