customerio-load-scale

Implement Customer.io load testing and horizontal scaling. Use when preparing for high traffic, running load tests, or designing queue-based architectures for scale. Trigger: "customer.io load test", "customer.io scale", "customer.io high volume", "customer.io k6", "customer.io performance test".

Quality

Content

65%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is highly actionable with complete, executable code across load testing, queueing, autoscaling, and batching. It is weakened by duplicated inline code that overlaps the reference file and by the absence of an explicit validation feedback loop for batch operations.

Suggestions

Replace the inline k6 script, queue worker, and batch sender with concise summaries that link to references/implementation-guide.md to remove duplication and respect token budget.

Add an explicit validation/feedback loop for load tests (e.g., 'if 429 error rate exceeds threshold, reduce rate by 25% and re-run') to satisfy the batch-operation validation expectation.

Add a clearly signaled pointer to the implementation guide in the body (e.g., 'See [implementation-guide.md](references/implementation-guide.md) for full scripts') so progressive disclosure is one level deep and navigable.

DimensionReasoningScore

Conciseness

The body is code-forward and avoids explaining basic concepts, but large inline code blocks (k6 script, queue worker, batch sender) duplicate material already present in references/implementation-guide.md, so it could be tightened by deferring to the reference rather than repeating.

2 / 3

Actionability

Provides fully executable k6 JavaScript, TypeScript BullMQ worker, Kubernetes HPA YAML, and batch sender code with concrete run commands, env vars, and install instructions — copy-paste ready.

3 / 3

Workflow Clarity

Steps 1–4 are clearly sequenced with a checklist and error-handling table, but for batch/load operations the rubric expects an explicit validate→fix→retry feedback loop, which is only implied rather than stated, capping clarity at 2.

2 / 3

Progressive Disclosure

The skill has a real reference bundle (references/implementation-guide.md) and section structure, but the body never signals or links to that reference and instead inlines the same material, so content that should be separate remains inline and references are not clearly signaled.

Description

90%

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 well-constructed with clear what/when guidance and strong, natural trigger terms. Its only weakness is that the capability list names just two actions rather than enumerating the full concrete feature set.

DimensionReasoningScore

Specificity

Names the domain and two concrete actions ("load testing" and "horizontal scaling") but does not enumerate a comprehensive list of specific actions, matching the score-2 anchor rather than the multi-action score-3 anchor.

2 / 3

Completeness

Explicitly states what the skill does ("Implement Customer.io load testing and horizontal scaling") and when to use it ("Use when preparing for high traffic, running load tests, or designing queue-based architectures"), satisfying both the what and when.

3 / 3

Trigger Term Quality

Provides five natural trigger phrases ("customer.io load test", "customer.io scale", "customer.io high volume", "customer.io k6", "customer.io performance test") that a user would plausibly say, giving good coverage rather than just a few relevant keywords.

3 / 3

Distinctiveness Conflict Risk

Scoped to a narrow niche (Customer.io load testing and scaling) with distinct, domain-specific triggers, making it unlikely to fire for unrelated skills.
