AiDex vs context-mode
AiDex: AiDex is an MCP server that gives AI coding assistants instant access to your entire codebase through a persistent, pre-built index. It works with any MCP-compatible AI assistant and reduces context consumption for code navigation by 50-80%. Featuring Tree-sitter parsing, incremental updates, and time-based filtering.; 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.

Features
AiDex01Tree-sitter Parsing for accurate identifier indexing
02~50 tokens per search vs 2000+ with grep
03Persistent index surviving between sessions
04Incremental updates and time-based filtering
05Zero external dependencies with SQLite WAL mode
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.
