cost-analysis

Analyze actual Azure spend, bill changes, and AKS or AI costs. WHEN: "Azure cost breakdown", "most expensive resources", "why did my bill increase", "cost spike", "unexpected charge", "Cosmos DB charges", "Foundry model costs", "AKS cluster cost", "namespace cost", "enable AKS cost analysis", "idle AKS capacity". DO NOT USE FOR: forecasts, pricing estimates, rightsizing, commitments, or budgets.

Quality

Content

82%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, token-efficient dispatch skill: an accurate overview table, lean workflow rules, and concrete error-handling guidance, with all body references resolving to real bundle files. The main gaps are the absence of explicit result-validation checkpoints in the workflow and reference nesting that goes two-to-three levels deep from SKILL.md rather than the ideal single level.

Suggestions

Add an explicit verification checkpoint to the workflow (e.g., 'cross-check a sample group's total against the overall total before reporting') to close the validation gap.

Flatten or surface the deeper chain (cost-investigation.md → cost-query/workflow.md → guardrails/examples) by linking key cost-query sub-files from the relevant first-level reference or consolidating them, so no path is more than one hop from its entry point.

DimensionReasoningScore

Conciseness

The ~37-line body is lean and earns every token: a compact intent-to-workflow dispatch table, a 5-step workflow, and an error-handling table. It assumes Claude's competence with no concept over-explanation or padding, matching the anchor-5 'lean and efficient' profile.

5 / 5

Actionability

Guidance is concrete and directive — named tools ('query_costs', 'query_aks_costs', Resource Graph), specific rules like 'Never transform MCP results in a shell or interpreter; request tool-side totals' and 'Retry once; then stop with the trace ID'. It falls short of anchor 5 because the body contains no copy-paste-ready commands or examples itself — the executable detail is delegated to the referenced workflow files, leaving minor gaps at the overview level.

4 / 5

Workflow Clarity

The 5-step workflow is clearly sequenced (confirm scope → load matching workflow → query tool-side → respect limits → separate measured from inferred), and the error-handling table provides recovery actions. It does not reach anchor 5 because there are no explicit validation/verification checkpoints on results (e.g., cross-checking totals or confirming data completeness) — 'Respect row limits and label incomplete data' gestures at it but is implicit. No destructive/batch cap applies since the skill is read-only analysis.

4 / 5

Progressive Disclosure

The Quick Reference table cleanly maps intents to workflow files and all referenced paths resolve to real files, with no inlined content that belongs elsewhere. However, the bundle nests beyond one level — e.g., SKILL.md → cost-investigation.md → cost-query/workflow.md → guardrails.md/examples.md is a three-hop chain — so it does not meet the anchor-5 'one-level-deep references' ideal, though it is well above anchor 3's unclear signaling.

Description

95%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 description: concrete capabilities, natural and comprehensive trigger phrases, and explicit use/don't-use boundaries. The only minor weakness is reliance on a single generic verb ('Analyze') rather than enumerating more distinct actions.

Suggestions

Consider enumerating distinct actions (e.g., 'query historical spend, investigate bill spikes, break down AKS namespace and AI service costs') instead of the single generic verb 'Analyze'.

DimensionReasoningScore

Specificity

The description names the domain and several specific capabilities — 'Analyze actual Azure spend, bill changes, and AKS or AI costs' — including named service surfaces ('Cosmos DB charges', 'Foundry model costs', 'namespace cost'). It falls short of anchor 5 because the action verbs are essentially one generic 'Analyze' over multiple objects rather than a list of distinct concrete actions, but it clearly exceeds anchor 3's '1-2 concrete actions' minimalism.

4 / 5

Completeness

It explicitly answers what ('Analyze actual Azure spend, bill changes, and AKS or AI costs') and when (a WHEN: clause with concrete trigger phrases), and goes further with an explicit DO NOT USE FOR exclusion list. This matches the anchor-5 pattern of both what and when with concrete trigger phrases; it is not merely the anchor-4 'when could be more explicit'.

5 / 5

Trigger Term Quality

The WHEN list is comprehensive natural language users would actually say: 'Azure cost breakdown', 'most expensive resources', 'why did my bill increase', 'cost spike', 'unexpected charge', 'Cosmos DB charges', 'AKS cluster cost', 'idle AKS capacity'. Coverage includes synonyms and service-specific variations, matching the anchor-5 example's breadth; nothing common is missing.

5 / 5

Distinctiveness Conflict Risk

It occupies a clear niche (actual Azure spend analysis, AKS/AI allocation) with distinct triggers, and the 'DO NOT USE FOR: forecasts, pricing estimates, rightsizing, commitments, or budgets' clause explicitly separates it from adjacent cost-management skills, minimizing wrong-skill triggering.
