✓
Purpose & Capability
Name and description match the SKILL.md content (parsing/validation/explanation of cron expressions). No unrelated environment variables, binaries, or install steps are requested.
✓
Instruction Scope
SKILL.md contains only cron format, examples, and validation rules; it does not instruct the agent to read files, access environment variables, call external endpoints, or perform any privileged operations.
✓
Install Mechanism
No install spec or code files are present; this is an instruction-only skill so nothing is written to disk or fetched at install time.
✓
Credentials
The skill requires no credentials, config paths, or environment variables — appropriate for a local parser/explainer.
✓
Persistence & Privilege
always is false and the skill does not request persistent/privileged presence or modify other skills or system settings.
Assessment
This skill appears safe and coherent: it only documents cron syntax and validation rules and requests no access to your system or secrets. Before installing, consider whether you want the agent to be able to edit or install cron jobs on your system — if you do, that would require additional permissions that this skill does not request. If a future version adds network access, file paths (e.g., /etc/crontab), or environment variables for system credentials, treat those changes as higher risk and re-evaluate.

Like a lobster shell, security has layers — review code before you run it.
