rails-ai-context vs context-mode
rails-ai-context: rails-ai-context auto-introspects your Rails app and provides context to AI assistants via MCP, saving tokens and reducing discovery overhead. It generates context files for multiple AI tools and offers 11 MCP tools with smart detail levels.; 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
rails-ai-context01Auto-introspection of entire Rails app (schema, models, routes, controllers, etc.)
0211 MCP tools with smart detail levels (summary, standard, full)
03Generates context files for Claude, Cursor, OpenCode, Windsurf, and GitHub Copilot
04Token savings up to 37% (measured benchmark)
05Works without a database by parsing db/schema.rb
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.
