Core Features

Context Saving

Sandbox tools keep raw data out of the context window, reducing data bloat by 98%.

Source: README
Session Continuity

Tracks all file edits, git operations, tasks, errors, and user decisions in SQLite, ensuring the model picks up exactly where the user left off.

Source: README
Think in Code

Encourages the use of scripts for analysis, reducing context usage by 100x compared to traditional tool calls.

Source: README
No Prose-style Enforcement

Keeps raw data out of context but does not dictate how the model writes its final answer, allowing for brevity and completeness in responses.

Source: README

Architecture

The architecture is modular, with distinct components for different platforms and functionalities. It employs design patterns like dependency injection for flexibility and uses a FTS5 knowledge base for efficient data retrieval.
