OpenCode Working Memory is a plugin that automatically captures and preserves project decisions, user preferences, architecture choices, and active session state for OpenCode AI agents. It operates without additional API calls by piggybacking on OpenCode's existing compaction process to extract and store memories.
This resource is most valuable during long-running development projects where maintaining consistent context about conventions, decisions, and preferences across multiple coding sessions is important. It's especially useful when working with complex codebases where the AI assistant needs to remember architecture decisions and project-specific patterns.
