model-usage

Use CodexBar CLI local cost usage to summarize per-model usage for Codex or Claude, including the current (most recent) model or a full model breakdown. Trigger when asked for model-level usage/cost data from codexbar, or when you need a scriptable per-model summary from codexbar cost JSON.

Quality

Content

93%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, well-structured overview that defers detail to a real reference file and an executable bundled script, with copy-paste-ready commands throughout. Only a minor explicit verification step is absent, which is acceptable for a read-only summarization skill.

DimensionReasoningScore

Conciseness

Lean and efficient: each section (Overview, Quick start, Current model logic, Inputs, Output, References) earns its place and assumes Claude's competence without explaining basic concepts; the lone TODO line is the only marginal token.

5 / 5

Actionability

Fully executable, copy-paste-ready commands with concrete flags and the bundled script path, covering the common provider/mode/format cases plus file and stdin input variants.

5 / 5

Workflow Clarity

The Quick start clearly sequences fetch-then-summarize for this single-purpose read-only skill, but there is no explicit output verification step, leaving it just below the top anchor.

4 / 5

Progressive Disclosure

Under 50 lines with well-organized sections and a single one-level-deep real reference (references/codexbar-cli.md) clearly signaled in the body, with the heavy lifting deferred to the bundled script — matching the simple-skill top anchor.

Description

87%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 specific, explicit about both capability and trigger conditions, and clearly niche-scoped to CodexBar per-model cost data. Its only weakness is reliance on product-specific jargon rather than a broader spread of natural synonyms.

DimensionReasoningScore

Specificity

Names the domain and several concrete actions ('summarize per-model usage', 'current (most recent) model', 'full model breakdown', 'scriptable per-model summary'), with only minor coverage gaps versus the comprehensive 5 anchor.

4 / 5

Completeness

Clearly answers 'what' (summarize per-model usage) and explicitly answers 'when' via a concrete trigger clause ('Trigger when asked for model-level usage/cost data from codexbar...'), matching the top anchor.

5 / 5

Trigger Term Quality

Good keyword coverage ('model-level usage/cost data', 'codexbar', 'per-model summary', 'codexbar cost JSON') but the terms are largely product-specific jargon with few natural synonyms or file extensions, falling short of comprehensive.

4 / 5

Distinctiveness Conflict Risk

Targets a clear niche (CodexBar CLI per-model local cost usage) with product-specific triggers, making it highly distinct with minimal conflict risk against other skills.
