mksglu/context-mode

Operates as an MCP server that intercepts tool outputs at the protocol layer, sandboxing large responses (56 KB Playwright snapshots, API logs) into local SQLite databases instead of flooding the context window—achieving 98% token reduction. Implements full-text search (FTS5/BM25) to retrieve only relevant session events during context compaction, preserving conversation continuity without re-injecting raw data. Integrates with Claude Code, Gemini CLI, and VS Code Copilot via hooks that automatically route tool calls, with zero cloud dependencies or telemetry.
