Discovery
17%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 description is extremely terse and narrowly scoped, describing a single mechanical action without explaining its purpose or when it should be triggered. It lacks natural trigger terms and a 'Use when...' clause, making it very difficult for Claude to know when to select this skill from a pool of options.
Suggestions
Add a 'Use when...' clause explaining the circumstances that should trigger this skill, e.g., 'Use when a health check, build verification, or smoke test output is needed.'
Include natural trigger terms a user might say, such as 'health check', 'smoke test', 'build verification', or 'status file'.
Expand the 'what' to explain the purpose of writing this file, e.g., 'Generates a deterministic OK status file at out/ok.txt to confirm successful build or test completion.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | It names a specific action ('write a deterministic OK file') and a specific output path ('out/ok.txt'), but describes only a single narrow action rather than listing multiple concrete capabilities. | 2 / 3 |
Completeness | It partially answers 'what' (write an OK file) but provides no 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per the rubric, a missing 'Use when' clause caps completeness at 2, and the 'what' is also minimal, warranting a 1. | 1 / 3 |
Trigger Term Quality | The description lacks natural keywords a user would say. Terms like 'deterministic OK file' and 'out/ok.txt' are highly specific internal jargon unlikely to match user queries naturally. | 1 / 3 |
Distinctiveness Conflict Risk | The very specific file path 'out/ok.txt' makes it somewhat distinctive, but the purpose is so unclear that it could be confused with other file-writing or testing skills without clearer context. | 2 / 3 |
Total | 6 / 12 Passed |
