Context-Engine-AI/Context-Engine
Context Engine is a code intelligence layer for AI coding assistants, delivered as a set of Model Context Protocol tools plus the agent skills that teach an assistant when to call them. Indexing runs over a workspace and then serves a default search tool that routes a query to the most suitable backend, whether semantic search, question answering, the symbol graph, tests or configuration. A symbol_graph tool navigates code structurally, resolving callers, callees, definitions, importers and subclasses, while pattern_search finds structural idioms such as retry loops, error handling or singletons across languages. Batch variants of search and graph queries exist specifically to cut token usage on repeated lookups. Persistent memory is provided by memory_store and memory_find, so knowledge survives between sessions, and cross_repo_search traces flows across repository boundaries. Git history is searchable through commit and path-history tools. Distribution is deliberately assistant-agnostic: the repository doubles as a Claude Code plugin marketplace, ships a .cursorrules file, a Codex skill directory, Windsurf and Augment layouts, and a GEMINI.md, and the plain SKILL.md works with any assistant that accepts custom instructions. For terminal workflows an MCP bridge installs from npm as ctxce, which authenticates, indexes a workspace, optionally watches it as a background daemon and then serves the tools over stdio or HTTP. The service side requires an account on the vendor''s site, and indexing can also be driven from a Visual Studio Code extension. The audience is developers working in large or multi-repository codebases where an assistant''s built-in file search is too shallow or too expensive in tokens.
