Description
Multi Agent Continuous Context Harness - MACCHA solves the problem that every AI coding session starts from zero. It combines a file-based 7-tier context architecture with a working memory engine (Memanto) that features vector embeddings, confidence decay, and semantic conflict detection — so Antigravity, OpenCode, and Claude Code all share the same persistent, self-improving brain. No 24/7 daemon needed.

Could you build this?
Yes A context harness managing memory files, vector embeddings, and LLM prompt context across coding CLI tools is a standard wrapper around embeddings and prompt engineering workflows.
Discussion
2 comments analyzed.
Concerns raised: Handling conflicts between outdated persistent memory and current repository state, API and architecture changes invalidating stored memory

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
