Mostly efficient for a complex domain skill, but includes motivational aphorisms ('Backups that aren't drilled drift toward useless', 'The runbook is for the worst night of someone's career') and re-derives basic definitions of RPO/RTO that could be trimmed.

Gives concrete, executable guidance: tiering scheme, RPO/RTO-to-architecture mappings, the 3-2-1 rule, an inventory table spec, and a fillable restore-runbook template reference. For an instruction-only planning skill this is copy-ready.

A clearly sequenced 7-step workflow with validation checkpoints and a feedback loop: drill, measure actual RPO/RTO against targets ('If the actual RTO was 6 hours when the target was 1 hour, the target is fiction'), document breaks, action items, and re-schedule.

SKILL.md is a well-organized overview with a single clearly signaled, one-level-deep reference (references/restore-runbook-template.md, verified to exist) linked from a dedicated 'Reference files' section.

Lists multiple concrete actions ('Plan and run backups, set recovery objectives, and run disaster recovery drills') rather than vague language, matching the top anchor.

Explicitly answers both what the skill does and when to use it via a clear 'Use this skill when...' clause plus 'Also triggers when...', satisfying the top anchor.

Strong natural-term coverage ('backup, restore, RPO, RTO, disaster recovery, DR... what if the database is gone, what if our hosting goes down, recovery drill, ransomware planning') including phrasings users would actually say.

Occupies a clear DR/backup niche with domain-specific triggers (RPO/RTO, ransomware, full-region outage) that are unlikely to fire for unrelated skills.
