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 capabilities (typed clients, retry logic, event batching, singleton management), and provides explicit trigger terms. The description is concise, uses third-person voice, and covers both what the skill does and when to use it.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: typed clients, retry logic, event batching, and singleton management. These are concrete, actionable 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. Very unlikely to conflict with other skills due to the narrow domain focus on Customer.io specifically. | 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 solid, actionable skill with production-quality TypeScript code examples covering four distinct Customer.io SDK patterns. Its main weaknesses are length (all patterns inline rather than split into referenced files) and the absence of validation/verification steps, particularly for the batching pattern where event delivery confirmation would be important. The error handling table is a nice touch but doesn't substitute for inline validation checkpoints.
Suggestions
Split each pattern into its own referenced file (e.g., TYPED_CLIENT.md, RETRY.md, BATCH.md, SINGLETON.md) and keep SKILL.md as a concise overview with the summary table and links.
Add validation/verification steps, especially for the batch queue pattern — e.g., how to confirm events were delivered, how to handle and log failed events from Promise.allSettled results.
Trim explanatory comments in code that Claude can infer (e.g., '// Define your event taxonomy as a union type', '// Don't retry client errors') to reduce token usage.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with executable code examples, but is quite long (~200+ lines of code). Some patterns could be more concise — e.g., the batch queue pattern includes boilerplate that could be trimmed. The summary tables and error handling tables add value but the overall length is substantial for what could be more tightly expressed. | 2 / 3 |
Actionability | All four patterns provide fully executable TypeScript code with file paths, imports, type definitions, and usage examples. The code is copy-paste ready with clear constructor parameters, environment variable references, and concrete usage snippets. | 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 client connection works, no testing steps for the retry logic, and no verification that batched events were actually delivered. The batch queue pattern involves potential data loss but lacks validation/verification steps. | 2 / 3 |
Progressive Disclosure | The content is well-structured with clear headings and a summary table, but all four substantial patterns are inline in a single file (~250 lines). The typed client, retry, batching, and singleton patterns could each be separate referenced files with SKILL.md serving as an overview. The 'Next Steps' reference to 'customerio-primary-workflow' is good but no bundle files exist to support progressive disclosure. | 2 / 3 |
