85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is highly actionable and well-sequenced with clear guardrails, and progressive disclosure is handled appropriately for a self-contained single-purpose skill. The main weakness is conciseness, where a few redundancies and chatty parentheticals could be trimmed without losing clarity.
Suggestions
Remove the redundant 'Acceptable nearby values' list in §3 since those values are already embedded in the cron-mapping table's 'divides cleanly' annotations, or keep only the list and drop the per-row annotations — don't carry both.
Delete the restating opening line 'This skill turns a free-form `[interval] <prompt>` line into a `cron` tool call and runs the prompt once right away.' since the description already says this, letting the body start at the parse step.
Tighten the §4 parentheticals (e.g. 'one-shot is wrong for `/loop` — one-shots come from natural-language scheduling') to bare instructions, keeping the rationale only where it prevents a real misuse.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and does not explain concepts Claude already knows, but it could be tightened: the opening line restates the description, the 'Acceptable nearby values' list duplicates the divides-cleanly values already shown in the §3 table, and chatty parentheticals in §4 ('one-shots come from natural-language scheduling') add tokens — placing it at 'could be tightened' rather than 'every token earns its place'. | 2 / 3 |
Actionability | Provides fully executable guidance — the exact regex `^\d+[smhd]$`, concrete cron-expression patterns per case in a table, the specific `cron` tool `schedule` verb with required `cron`/`prompt` params, and a copy-paste-ready examples table; matches the 'fully executable, specific examples' anchor. | 3 / 3 |
Workflow Clarity | The five-step process is clearly sequenced (parse → autonomous case → map to cron → call cron → execute immediately) with explicit early-exit checkpoints ('If the input is empty... Do not schedule anything', 'After the cron call succeeds') and guardrails in the 'Do not' section; no destructive/batch operation is involved so the absence of a validate-fix-retry loop does not cap the score. | 3 / 3 |
Progressive Disclosure | No bundle files exist and the skill is appropriately self-contained, organized into seven clearly labeled sections with no material that warrants splitting to a deeper file; it is a well-organized single-file overview rather than a monolithic wall of text. | 3 / 3 |
