80%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is an efficient, well-structured tool wrapper with concrete examples and a useful time-expression mapping. Its main weakness is the destructive remove operation lacking any validation or confirmation guidance, which caps workflow clarity.
Suggestions
Add a validation step before removal, e.g. 'Run cron(action="list") first to confirm the job_id, then remove.'
Clarify the one-time `at` parameter with a concrete computed ISO datetime example rather than a placeholder.
Note that one-time jobs auto-delete after running so users know no cleanup is needed.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean: it states the three modes, gives concrete tool calls, and a compact time-expression table without explaining what cron is or padding with concepts Claude already knows; every section earns its place. | 5 / 5 |
Actionability | Examples are concrete, copy-paste tool calls covering add/list/remove and the common time patterns; the `at="<ISO datetime>"` placeholder is a minor gap that keeps it just below fully executable 5. | 4 / 5 |
Workflow Clarity | The skill includes the destructive 'remove' operation (`cron(action="remove", job_id="abc123")`) with no validation step such as listing first or confirming the job_id; per the judging guidelines, missing validation in a destructive operation caps workflow_clarity at 3 despite the otherwise simple single-purpose design. | 3 / 5 |
Progressive Disclosure | The skill is under 50 lines, self-contained with no external references needed, and well-organized into clear sections (Three Modes, Examples, Time Expressions); per the simple-skill guidance this qualifies for 5 on well-organized sections alone. | 5 / 5 |
