customerio-sdk-patterns
Apply production-ready Customer.io SDK patterns. Use when implementing typed clients, retry logic, event batching, or singleton management for customerio-node. Trigger: "customer.io best practices", "customer.io patterns", "production customer.io", "customer.io architecture", "customer.io singleton".

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-crafted skill description that clearly identifies its niche (Customer.io SDK patterns), lists specific concrete capabilities, and provides explicit trigger terms. The 'Use when' clause and enumerated trigger phrases make it easy for Claude to select this skill appropriately. The description is concise without being vague.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: typed clients, retry logic, event batching, and singleton management. These are clearly defined implementation patterns rather than vague abstractions. | 3 / 3 |
Completeness | Clearly answers both 'what' (apply production-ready Customer.io SDK patterns including typed clients, retry logic, event batching, singleton management) and 'when' (explicit 'Use when' clause and 'Trigger' terms provided). | 3 / 3 |
Trigger Term Quality | Includes explicit trigger terms that users would naturally say: 'customer.io best practices', 'customer.io patterns', 'production customer.io', 'customer.io architecture', 'customer.io singleton'. Also mentions 'customerio-node' as the specific package name. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — targets a specific SDK (customerio-node) with specific patterns (retry logic, event batching, singleton management). Very unlikely to conflict with other skills given the narrow domain focus. | 3 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured, highly actionable skill with production-ready TypeScript patterns for Customer.io. Its main weakness is length—four complete pattern implementations inline make it token-heavy, and the content would benefit from splitting patterns into separate files with a concise overview in SKILL.md. Adding validation/verification steps (e.g., how to confirm events are received) would strengthen workflow clarity.
Suggestions
Move individual pattern implementations to separate files (e.g., patterns/typed-client.ts, patterns/retry.ts) and keep only brief descriptions with links in SKILL.md to improve progressive disclosure and conciseness.
Add a verification step for each pattern—e.g., 'Check Customer.io Activity Log to confirm events arrive' or a simple test snippet—to improve workflow clarity.
The Promise.allSettled results in the batch queue are silently discarded; add guidance on logging or handling rejected promises to complete the error handling story.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient with executable code examples, but is quite lengthy (~250 lines of code). Some patterns could be more concise—e.g., the batch queue pattern includes implementation details Claude could infer. The overview and prerequisites sections add minor fluff ('Understanding of your event taxonomy'). | 2 / 3 |
Actionability | All four patterns provide fully executable TypeScript code with complete implementations, proper imports, usage examples, and environment variable handling. The code is copy-paste ready with clear file path comments. | 3 / 3 |
Workflow Clarity | The patterns are presented as independent modules rather than a sequenced workflow, which is appropriate. However, there are no validation checkpoints—e.g., no guidance on verifying the typed client works, no testing steps for retry logic, and the batch queue lacks error reporting on failed events from Promise.allSettled results. | 2 / 3 |
Progressive Disclosure | The content has good structure with clear pattern headings, summary table, and error handling table. However, all four substantial patterns are inline rather than split into separate files, making this a long monolithic document. The references to external resources and next steps are well-signaled. | 2 / 3 |
