context-mode vs nexo
context-mode: Every tool call in an MCP (Model-Controller-Program) environment dumps raw data into the context window, quickly consuming space and causing the agent to lose track of ongoing tasks. Context Mode is an MCP server that tackles this by sandboxing tool outputs to significantly reduce context usage, tracking session events in SQLite for continuity, and promoting 'think in code' to minimize data processing within the LLM.; nexo: NEXO Brain is a local cognitive runtime that provides persistent memory, durable workflow execution, and a shared brain across multiple AI coding agents. It implements cognitive science concepts like forgetting curves, semantic search, and overnight learning to turn stateless assistants into cognitive partners. With 150+ MCP tools and support for Claude Code, Codex, Claude Desktop, and others, it enhances AI agents with long-term memory and adaptive behavior.

Features
context-mode01Context Saving: Sandbox tools keep raw data out of the context window, achieving up to 98% reduction.
02Session Continuity: Tracks every file edit, git operation, task, and user decision in SQLite for seamless session resume.
03Think in Code: Promotes LLMs to program analysis, not compute it, saving 100x context by logging only results.
04Batch Execution & Search: Run multiple commands/queries in one call with tools like `ctx_batch_execute`.
05Advanced Knowledge Base: Uses SQLite FTS5 with BM25 ranking, smart snippets, and TTL cache for efficient information retrieval.
nexo01Persistent memory across sessions with natural decay and reinforcement
02Semantic search by meaning using vector embeddings
03Cognitive Cortex middleware for thinking before acting
04Durable workflow runtime for multi-step execution
05Overnight learning (Deep Sleep) for automatic memory consolidation
