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

80%Weight 40%Scale 1-3

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

Strong on actionability and conciseness with excellent executable examples, but weaker on workflow structure and progressive disclosure. Batch operations lack embedded validation feedback loops, and the available bundle reference is not used to split out detail.

Suggestions

Add an explicit validate→fix→retry loop for the batch sender and queue worker (e.g., check 429/error rates, back off, and retry) so batch workflows clear the workflow_clarity bar for 3.

Reference references/implementation-guide.md from the body for the deeper setup/architecture detail, and move the full code blocks or extended configuration there to keep SKILL.md an overview.

Link the 'customerio-known-pitfalls' pointer (Next Steps) as an explicit one-level-deep reference and surface the implementation guide alongside it for clearer navigation.

DimensionReasoningScore

Conciseness

The body is lean and assumes competence — it does not explain what k6, BullMQ, or HPA are, and every section is executable code or a directly useful table/checklist with no padding.

3 / 3

Actionability

Provides fully executable, copy-paste-ready artifacts: a complete k6 script with run command, a BullMQ worker, an HPA YAML, and a batch sender, plus the exact npm install line.

3 / 3

Workflow Clarity

Steps 1–4 are clearly sequenced and a Load Test Checklist adds safety items, but the batch/queue workflows lack an explicit validate→fix→retry feedback loop embedded in the process, which caps batch-operation workflows at 2.

2 / 3

Progressive Disclosure

The body is a ~320-line monolith with all detail inline, and the bundled references/implementation-guide.md is never referenced from the body — content that could be offloaded stays inline and the one bundle file is orphaned.

Description

100%Weight 40%Scale 1-3

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 well-formed description that concretely states capabilities, gives explicit use-when guidance, and lists natural trigger phrases. It is concise, distinct, and uses appropriate third-person voice.

DimensionReasoningScore

Specificity

Names multiple concrete actions — "Implement Customer.io load testing and horizontal scaling" and "designing queue-based architectures for scale" — rather than vague language.

3 / 3

Completeness

Clearly states both what it does (load testing + horizontal scaling) and when to use it ("Use when preparing for high traffic, running load tests, or designing queue-based architectures for scale"), plus explicit trigger phrases.

3 / 3

Trigger Term Quality

Includes an explicit Trigger list with natural phrases users would say: "customer.io load test", "customer.io scale", "customer.io high volume", "customer.io k6", "customer.io performance test".

3 / 3

Distinctiveness Conflict Risk

The Customer.io-specific niche and distinctive trigger phrases make it unlikely to fire for an unrelated skill.
