go-cache

Generate two files for every cache: a port interface and a Redis-backed implementation.

| Flag, existence check, rate limit | Boolean flag | bool | | Structured data — tokens, sessions, profiles | JSON data | dto.XxxData |

Use when caching simple existence flags, presence checks, or rate limit states.

Generate Go cache implementations following GO modular architecture conventions. Always use this skill when the user asks to create a cache, add a Redis cache layer, cache short-lived data with TTL, implement rate limiting storage, OTP caching, session caching, OAuth state storage, or any domain cache in internal/modules/<module>/cache/. Invoke proactively whenever the user mentions caching, Redis-backed storage, TTL expiry, or temporary data — even if they don't say "cache" explicitly. Source: cristiano-pacheco/ai-rules.
