ai-devkit vs xerj

ai-devkit: AI DevKit is a local-first operating layer for teams running several coding agents. One .ai-devkit.json reconciles skills, MCP and setup across Claude Code, Codex CLI, Gemini CLI, opencode, Pi, Cursor, Copilot and others; agent console is a live TUI for running sessions; agent send routes prompts, logs or stdin to a running agent; and a local SQLite memory is searched over MCP when needed. A dev-lifecycle skill guides requirements, design, planning, implementation, testing and review.; xerj: XERJ is a single Rust binary that auto-indexes any folder (code, docs, logs, CSV, PDFs) for BM25, vector and hybrid search behind an Elasticsearch-compatible API. It plugs into Claude Code, Cursor and other MCP clients so agents retrieve exact passages instead of reading files one by one.
