LeanCTX — Context Engineering for AI Agents

LeanCTX optimizes LLM context through 82 MCP tools, 95+ shell compression patterns, and tree-sitter AST parsing for 26 languages. It provides adaptive file reading, cross-session memory (CCP), task-conditioned relevance scoring, and a feedback loop for learning optimal compression.
