review-scale-and-resilience

Review a code change for load, data-volume, concurrency, retry, rollout, dependency-failure, latency, throughput, timeout, and fault-tolerance risks. Use when reviewing for performance under load, scalability, resilience, or failure handling.

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.

An exceptionally lean, actionable review-lens skill: every directive is specific, the scope/threshold/reporting sections are tight and unambiguous, and the small size needs no external references. The only gap is that the review method's sequence is implicit rather than an explicit numbered workflow.

Suggestions

Consider presenting the Method section as a short numbered sequence (1. prioritize request paths/fan-out/batch work, 2. derive failure cases from operations, 3. read the AGENTS.md/CLAUDE.md chain, 4. apply the threshold, 5. report) so the review order is explicit.

Adding a one-line example of a well-formed finding (fault that triggers it, what breaks, and the containing bound/timeout/checkpoint) would make the Reporting requirements concrete.

DimensionReasoningScore

Conciseness

The body is lean with every line earning its place — e.g., 'Prioritize work on request paths, fan-out operations, and batch processing' and 'Do not report cold-path inefficiencies or scenarios that depend on several unlikely failures occurring together' — with no padding and no re-explanation of concepts Claude already knows.

5 / 5

Actionability

Concrete, unambiguous directives throughout: 'Derive failure cases from the operations the change performs, including external calls, writes, and retries. Check behavior for delayed, duplicate, and missing responses', 'Read the `AGENTS.md` or `CLAUDE.md` chain... from the repository root down', and the precise reporting rule 'do not present concurrency limiting as sufficient when the operation can be batched'. As an instruction-only skill, its guidance is fully actionable without code.

5 / 5

Workflow Clarity

A clear implicit sequence is present (prioritize targets → derive failure cases → consult project rules → apply threshold → report with named fault, bound, and timeout), but the steps are not explicitly numbered and no checkpoint verifies the report against the threshold before finishing. As a read-only review skill it needs no destructive-operation validation loop, so it stays above the anchor-3 level.

4 / 5

Progressive Disclosure

The skill is under 50 lines with no need for external references, and its well-organized sections (Scope, Method, Threshold, Reporting) satisfy the simple-skill exception for a top progressive-disclosure score.

Description

88%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: it names a concrete action, enumerates the risk categories comprehensively, and pairs it with an explicit 'Use when' clause of natural trigger phrases. The only weaknesses are a few missing common synonyms and minor overlap with adjacent review skills.

DimensionReasoningScore

Specificity

The description gives a concrete action ('Review a code change for') with an exhaustive enumeration of specific risk categories — 'load, data-volume, concurrency, retry, rollout, dependency-failure, latency, throughput, timeout, and fault-tolerance risks' — providing comprehensive coverage of the domain with no minor gaps.

5 / 5

Completeness

Both 'what' (review a code change for the enumerated risk categories) and 'when' ('Use when reviewing for performance under load, scalability, resilience, or failure handling') are explicitly stated with concrete trigger phrases, matching the anchor-5 example structure.

5 / 5

Trigger Term Quality

Natural trigger phrases users would actually say are present ('performance under load', 'scalability', 'resilience', 'failure handling'), but a few common synonyms such as 'reliability', 'high traffic', or 'backpressure' are missing, keeping it below the comprehensive anchor.

4 / 5

Distinctiveness Conflict Risk

The scale-and-resilience review lens is a clear niche, but 'performance' and general review phrasing create minor overlap risk with a performance-review or general code-review skill.
