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 MCP skill body: fully concrete tool invocations, a clear seven-step sequence with performance-note checkpoints, useful troubleshooting, and example query mappings. The main gaps are minor — repeated invocation blocks and an inlined reference table that could live in a separate file, plus no confirmation step before the state-changing anomaly-dismiss action.

Suggestions

Consolidate the seven repeated "Call MCP tool: harness_get / Parameters: resource_type: X" blocks into a compact pattern stated once plus a table of resource_type values, trimming the duplication with the Cost Resource Types Reference section.

Add an explicit validation/confirmation checkpoint before Step 6's harness_execute anomaly-dismiss action (e.g., confirm with the user that the anomaly is a known false positive before sending report_feedback).

Move the Cost Resource Types Reference table and/or the report-format template into a references/ file linked from the overview to make progressive disclosure explicit and keep SKILL.md lean.

DimensionReasoningScore

Conciseness

The body is lean — no explanations of concepts Claude already knows, and every section adds operational value. It is not a 5 because the seven near-identical "Call MCP tool: harness_get / Parameters: resource_type:" blocks repeat the same invocation pattern, and the Cost Resource Types Reference table partially duplicates the step content. This matches anchor 4: efficient with minor instances that could be trimmed.

4 / 5

Actionability

Every step gives the exact MCP tool name, resource_type, and parameters; the anomaly-dismiss call includes a complete body ({ feedback: "FALSE_ANOMALY" } with the other enum values); and the Examples section maps natural queries to specific tool calls. This is copy-paste-ready executable guidance covering the common cases, matching anchor 5.

5 / 5

Workflow Clarity

Steps 1-7 are clearly sequenced, and Performance Notes supply checkpoints ("Verify savings estimates before presenting", "Cross-reference recommendations with anomaly data to distinguish trends from spikes"). It is not a 5 because the state-changing harness_execute operation (dismissing an anomaly) has no explicit confirmation or validation step before it runs — a minor validation gap consistent with anchor 4.

4 / 5

Progressive Disclosure

The single file is well-sectioned with clear headers and no nested references, and no bundle files exist to mis-navigate. However, the 13-row resource-types reference table and the report-format template are inlined reference material that could be split into a separate file to keep the overview lean, so structure is good with minor organization gaps (anchor 4) rather than the ideal split of anchor 5.

Description

83%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 that explicitly states both capabilities and trigger conditions in third-person voice, with concrete quoted trigger phrases. Minor improvements possible by broadening trigger synonyms and mentioning the fuller capability set (perspectives, commitments) reflected in the body.

DimensionReasoningScore

Specificity

"Analyze cloud costs, find optimization opportunities, and track anomalies" names the domain (Harness CCM via MCP) plus three concrete actions, but coverage is not comprehensive — perspectives, commitment analysis, and report generation from the body are absent. This lists several specific actions with minor gaps (anchor 4), not the comprehensive coverage of anchor 5.

4 / 5

Completeness

Explicitly answers both: what it does ("Analyze cloud costs, find optimization opportunities, and track anomalies using Harness CCM via MCP") and when to use it ("Use when user says ... or asks about cloud bills") with concrete trigger phrases. This clearly matches the anchor-5 example pattern; anchor 4 would require the 'when' to be less explicit than it is.

5 / 5

Trigger Term Quality

Six natural trigger phrases ("cloud costs", "analyze costs", "cost optimization", "reduce spending", "cost report", "cloud bills") give good keyword coverage, but common synonyms users would say — "spend", "billing", "cloud bill", "save money", "FinOps" — are missing. Good coverage with a few natural terms absent matches anchor 4.

4 / 5

Distinctiveness Conflict Risk

The Harness CCM niche is mostly distinct with cost-specific triggers, but phrases like "reduce spending" and "cost report" could overlap with generic expense-analysis or finance skills. Minor overlap risk with closely related skills is anchor 4; anchor 5 would require all triggers to be as distinct as "cloud costs".
