speciflow

Persistent cross-session memory for AI agents. Two storage modes: semantic vector search (mem_*) for knowledge found by meaning, and key-value store (kv_*) for instant lookup. Auto-expiry via TTL + volatile-lru eviction.

Flow-enforcement engine for coding agents: declarative yamlgraph recipes, durable runs, deterministic evidence gates

Plugin from sergesha/claude-essentials
