Conciseness

Mostly lean, directive prose with tables and checklists, but a few lines restate what Claude already knows ('RPO is the maximum age of data that's acceptable to lose, measured in time', 'If your backup is encrypted with a key you've lost, the backup is useless') and some rhetorical padding ('It happens. Plan as if it will'). Fits anchor 4 ('minor instances of over-explanation that could be trimmed') rather than anchor 5's 'every token earns its place'.

Actionability

Concrete, executable-by-an-agent guidance throughout: tier definitions with examples, an RTO-to-architecture mapping table, architecture requirements (30+ day retention, 3-2-1 rule, object lock), drill types with a specific cadence ('quarterly tabletop, annual partial drill'), and a fillable runbook template. Not anchor 5 because there are no worked examples (e.g., a filled-in inventory row or sample runbook entry) and all guidance is platform-abstract — minor gaps rather than copy-paste-ready coverage of common cases.

Workflow Clarity

The 7-step workflow (inventory → set targets → verify architecture → document runbook → run drill → document results → schedule next drill) is clearly sequenced with explicit validation: drills verify restores, and Step 6 is a feedback loop ('If the actual RTO was 6 hours when the target was 1 hour, the target is fiction. Either fix the gap or revise the target'). Matches anchor 5's 'explicit validation steps; feedback loops'; the destructive-operation cap does not apply since validation is built in.

Progressive Disclosure

The only bundle artifact users fill in (the restore runbook) is correctly offloaded to a real, well-signaled one-level-deep reference with a description of what it covers; the remaining body is the core planning framework that belongs inline. Matches anchor 5 ('well-signaled one-level-deep references; content appropriately split'), not anchor 4's 'minor organization gaps'.

Specificity

Lists multiple concrete actions ('Plan and run backups, set recovery objectives, and run disaster recovery drills') plus further specifics in the when-clause (defining RPO/RTO targets, designing backup architecture, deciding what to back up and how often, running a restoration drill). Comprehensive coverage in third-person voice; fits the anchor-5 example's level, clearly above anchor 4's 'minor gaps in coverage'.

Completeness

Explicitly answers both what (backup planning, recovery objectives, DR drills) and when ('Use this skill when defining RPO/RTO targets... Triggers on backup, restore, RPO, RTO...') with concrete trigger phrases. Matches the anchor-5 good_overall example pattern exactly; clearly above anchor 4's 'when could be more explicit'.

Trigger Term Quality

Comprehensive natural terms with synonyms and phrasings users actually say: 'backup, restore, RPO, RTO, disaster recovery, DR, business continuity, what if the database is gone, what if our hosting goes down, recovery drill, ransomware planning'. Matches anchor 5's coverage including variants; not anchor 4, which expects 'a few natural terms missing'.

Distinctiveness Conflict Risk

Mostly a clear DR/backup-planning niche with distinct triggers, but 'Also triggers when an incident reveals a gap in restoration capability' claims incident-adjacent territory that overlaps with an incident-response skill, and bare 'backup'/'restore' could catch routine-snapshot questions. Fits anchor 4 ('minor overlap risk with closely related skills') better than anchor 5's 'minimal conflict risk'.
