cosid-sharding skillA

Name: cosid-sharding
Author: ahoo-wang

cosid-sharding is agent-read markdown (skill) from ahoo-wang/skills: Design, implement, and validate CosId database sharding with core ModCycle, IntervalTimeline, CachedSharding, and SnowflakeLocalDateTimeConvertor APIs or ShardingSphere COSID_MOD, COSID_INTERVAL, and COSID_INTERVAL_SNOWFLAKE algorithms. Use for modulo routing, date/time partitions, Snowflake timestamp routing, exact/IN/range behavior, effective nodes, suffix naming, or routing tests. Do not use for choosing an ID generator unless sharding is the primary concern..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
