Lists multiple specific concrete actions: 'analyzing what a deploy changes', 'recommending revert, roll-forward, feature-flag kill, or data repair', and mentions 'reversibility' as a decision factor. These are concrete, actionable capabilities.

Clearly answers both what ('Advises on rollback strategies by analyzing what a deploy changes — recommending revert, roll-forward, feature-flag kill, or data repair') AND when ('Use during an incident when a deploy went bad, when designing a deploy pipeline and the user asks how to make it reversible, or when a migration needs an undo plan').

Includes natural keywords users would say: 'rollback', 'deploy', 'incident', 'revert', 'roll-forward', 'feature-flag', 'migration', 'undo plan', 'reversible', 'deploy pipeline'. Good coverage of terms across incident response and deployment planning contexts.

Clear niche focused specifically on rollback/revert strategies for deployments. The combination of incident response, deploy pipeline design, and migration undo planning creates a distinct scope unlikely to conflict with general deployment or incident skills.

Every section earns its place with no unnecessary explanations of basic concepts. The tables are dense with information, the decision tree is compact, and there's no padding or verbose introductions.

Provides concrete commands (`kubectl rollout undo`, `pg_dump`), specific SQL patterns, exact output formats, and a complete worked example. The decision tree gives explicit paths to follow.

The decision tree provides clear sequencing, the data repair section has explicit numbered steps with validation (snapshot before repair), and the worked example demonstrates the full decision process with checkpoints.

Content is well-organized with clear sections, but it's a moderately long single file. The reference to `cd-pipeline-generator` suggests related skills exist but navigation to them isn't clearly structured. Could benefit from splitting design-time vs incident-mode into separate files.
