Implement Customer.io primary messaging workflow. Use when setting up campaign triggers, welcome sequences, onboarding flows, or event-driven email automation. Trigger: "customer.io campaign", "customer.io workflow", "customer.io email automation", "customer.io messaging", "customer.io onboarding".

Discovery
89%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 solid skill description that clearly identifies its niche (Customer.io messaging workflows) and provides explicit trigger guidance. Its main weakness is that the capability description stays at a category level rather than listing granular concrete actions. The explicit trigger terms and 'Use when' clause make it highly functional for skill selection.
Suggestions
Add more specific concrete actions such as 'configure event triggers', 'build multi-step workflows', 'set up segment filters', or 'define delay and branching logic' to improve specificity.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Customer.io messaging workflow) and some actions (campaign triggers, welcome sequences, onboarding flows, event-driven email automation), but doesn't list truly concrete actions like 'create segments', 'configure webhooks', or 'set delay timers'. The actions are more category-level than step-level. | 2 / 3 |
Completeness | Clearly answers both 'what' (implement Customer.io primary messaging workflow including campaign triggers, welcome sequences, onboarding flows, event-driven email automation) and 'when' (explicit 'Use when' clause plus a dedicated 'Trigger' list with specific phrases). | 3 / 3 |
Trigger Term Quality | Includes a well-structured set of natural trigger terms that users would actually say: 'customer.io campaign', 'customer.io workflow', 'customer.io email automation', 'customer.io messaging', 'customer.io onboarding'. These cover the main variations a user would naturally use when requesting this skill. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive due to the specific 'Customer.io' platform branding in every trigger term. This is unlikely to conflict with generic email or messaging skills, as the triggers are all scoped to Customer.io specifically. | 3 / 3 |

Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, actionable skill with executable TypeScript code and a well-sequenced workflow covering the full Customer.io messaging integration. The ASCII diagram and error handling table add practical value. The main weakness is moderate verbosity — the event taxonomy includes unused events, and some inline content could be split into supporting files for better progressive disclosure.
Suggestions
Trim the CIO_EVENTS taxonomy to only events actually used in subsequent steps, or move the full taxonomy to a separate reference file
Remove JSDoc comments on service methods that restate what the method name already conveys (e.g., '/** Call on user signup — creates profile and triggers onboarding campaign */')
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably well-structured but includes some unnecessary verbosity. The event taxonomy in Step 1 lists many events (commerce, lifecycle) that aren't used in subsequent steps, and some method-level JSDoc comments explain things Claude would infer. The ASCII diagram and Liquid template table are efficient, but the overall content could be tightened. | 2 / 3 |
Actionability | The skill provides fully executable TypeScript code across all steps — from event definitions to service class to route integration. Code is copy-paste ready with concrete examples, specific API calls, and real parameter values. The dashboard configuration steps are also specific and actionable. | 3 / 3 |
Workflow Clarity | The 4-step workflow is clearly sequenced (define events → build service → integrate routes → configure dashboard). The ASCII diagram shows the data flow between app, dashboard, and user. The dashboard campaign configuration includes explicit branching logic and wait steps. The error handling table serves as a validation/troubleshooting checkpoint. | 3 / 3 |
Progressive Disclosure | The skill references external docs and a next-step skill (`customerio-core-feature`), but all content is inline in a single file that's quite long. The event taxonomy, service class, and route integration could potentially be split into referenced files. However, for a skill with no bundle files, the organization is reasonable with clear section headers. | 2 / 3 |
