The other half of the context problem.
Context Mode is not a CLI output filter or a cloud analytics dashboard. It operates at the MCP protocol layer — raw data stays in a sandboxed subprocess and never enters your context window. Web pages, API responses, file analysis, Playwright snapshots, log files — everything is…
What it does
- Reduces context window usage by intercepting and summarizing raw tool output.
- Maintains session continuity by indexing events in a local SQLite database.
- Operates in a sandboxed subprocess to ensure data privacy.
- Provides BM25 search to retrieve only relevant historical session data.
- Supports automatic routing enforcement for Claude Code.

The real split here is workflow fit, not raw counts. Context Mode: Managing large log files or API responses without exhausting the LLM context window. Semiotic: Generating correct chart code for React applications using AI coding assistants. Context Mode also has the larger public footprint (5.6k vs 2.6k stars).
