Lists multiple specific concrete actions: 'Plan and run backups, set recovery objectives, and run disaster recovery drills.' Further elaborated with 'defining RPO/RTO targets, designing backup architecture, deciding what to back up and how often, planning for full-region or platform outages, running a restoration drill.'

Clearly answers both 'what' (plan/run backups, set recovery objectives, run DR drills) and 'when' with an explicit 'Use this skill when...' clause plus a detailed 'Triggers on' list. Also includes an edge-case trigger: 'when an incident reveals a gap in restoration capability.'

Excellent coverage of natural trigger terms including technical abbreviations (RPO, RTO, DR), full phrases (disaster recovery, business continuity), and natural user language ('what if the database is gone', 'what if our hosting goes down', 'ransomware planning'). Covers both formal and informal ways users would express these needs.

Occupies a clear niche around backup, disaster recovery, and business continuity planning. The specific triggers like RPO, RTO, DR drills, and ransomware planning are highly distinctive and unlikely to conflict with general infrastructure or incident response skills.

The content is well-organized and mostly efficient, but includes some sections that could be tightened—e.g., the 'When NOT to use' section, the 'Special topics' section on file storage and code backups covers ground Claude already knows (what S3 versioning is, that code lives in Git). Some failure patterns are repetitive with earlier guidance. However, the framework and workflow sections earn their tokens.

The skill provides a clear framework and structured workflow with specific tables and checklists, but lacks executable code or commands. Restore steps say 'the exact restore steps (commands, screenshots, sequence)' without providing any concrete examples. No specific backup tool commands, CLI examples, or configuration snippets are given—it's a planning guide rather than an executable playbook.

The 7-step workflow is clearly sequenced with logical progression from inventory through drilling and scheduling. It includes explicit validation checkpoints (Step 5: drill, Step 6: document results comparing actual vs. target RPO/RTO), feedback loops (if actual RTO exceeds target, fix or revise), and a clear 'untested backups are not backups' philosophy throughout.

The skill references one external file (restore-runbook-template.md) which is appropriate, but the bundle doesn't actually include it. The main document is quite long (~300 lines) with special topics and failure patterns that could be split into separate reference files. The structure within the document is good with clear headers, but the monolithic length works against progressive disclosure.
