managing-database-sharding

Quick Review

This skill provides a generic framework for database sharding but lacks specificity in its description and implementation guidance. The description is too vague for a CLI agent to understand what sharding strategies are available or when to use them. While the generic 5-step process (Assess, Design, Implement, Validate, Deploy) is well-structured, it lacks concrete sharding-specific knowledge such as shard key selection, consistent hashing strategies, range vs. hash partitioning, or cross-shard transaction handling. The scripts directory suggests practical tools exist (init_sharding.py, rebalance_shards.py, cross_shard_query.py), and the skill references these appropriately. However, the SKILL.md itself reads like a template rather than domain-specific guidance—most content could apply to any backend task. For a complex topic like sharding that requires understanding of partition strategies, data distribution, and rebalancing, the skill needs more concrete decision frameworks and sharding-specific knowledge to justify its existence over a general CLI agent.
