sync-mutex

The sync-mutex skill appears coherent with its stated purpose: it documents and orchestrates a Redis-based distributed lock lifecycle with ownership checks, lease extensions, and retry behavior. It does not introduce unfamiliar or external dependencies, nor does it request arbitrary credentials or perform external communications beyond Redis interactions. Security considerations center on standard Redis coordination: ensure Redis credentials and traffic are securely configured (TLS, authentication, least-privilege tokens) in the deployment environment. Overall, the footprint is benign and proportionate to its purpose, with moderate data-flow risk that is typical for a distributed lock mechanism.
