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 communicates when to use it (adding logs, debugging, working with Logger) and what it covers (constructor-injection, child loggers, env-var config, test mocking). The trigger terms are well-chosen for the developer audience. Minor improvement could come from listing more concrete actions rather than topic areas.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Logger, SDK, container runtime) and some actions (adding logs, debugging, constructor-injection pattern, child loggers, env-var configuration, test mocking), but the actions are more like topic areas than concrete verbs describing what the skill does. It doesn't list specific concrete actions like 'create child loggers' or 'configure log levels via environment variables'. | 2 / 3 |
Completeness | Explicitly answers both 'what' (covers constructor-injection pattern, child loggers, env-var configuration, and test mocking) and 'when' ('Use when adding logs, debugging, or working with the Logger across the SDK and container runtime'). The 'Use when...' clause is present and clear. | 3 / 3 |
Trigger Term Quality | Includes strong natural trigger terms users would say: 'logs', 'debugging', 'Logger', 'child loggers', 'env-var configuration', 'test mocking', 'constructor-injection'. These cover the common ways a developer would phrase requests related to logging in an SDK/container context. | 3 / 3 |
Distinctiveness Conflict Risk | Clearly scoped to Logger functionality within a specific SDK and container runtime context. The combination of logging, constructor-injection, child loggers, and env-var configuration creates a distinct niche that is unlikely to conflict with other skills. | 3 / 3 |

Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a high-quality, concise skill that efficiently communicates the logging conventions for the project. It provides executable code examples, a clear configuration table, and specific guidance on log levels and test mocking—all without over-explaining concepts Claude already understands. The structure is clean and scannable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every section is lean and purposeful. No unnecessary explanations of what logging is or how DI works. The child logger guidance and log-level table are compact yet informative. The only slightly verbose bit is the test section's second sentence, but it earns its place as a safety guardrail. | 3 / 3 |
Actionability | Provides executable TypeScript examples for the core pattern (constructor injection), child loggers, and test mocking. The env-var table gives exact variable names and allowed values. The log-level guidelines are specific and include a concrete example of structured error logging. | 3 / 3 |
Workflow Clarity | This is a pattern/convention skill rather than a multi-step destructive workflow, so explicit validation checkpoints aren't required. The single-task guidance is unambiguous: inject logger via constructor, create child loggers at work boundaries, use NoOp in tests, follow the level guidelines when adding logs. The sequence of sections naturally guides from setup to usage to testing. | 3 / 3 |
Progressive Disclosure | The content is under 50 lines, well-organized into clearly headed sections (Pattern, Configuration, Tests, When Adding Logs), and doesn't need external references. No monolithic walls of text or unnecessary nesting. The structure supports quick scanning. | 3 / 3 |
