Mouse: Coordinate-Based Editing Staged Changes and Atomic Rollback for AI Coding Agents

Mouse from HIC AI provides precision file-editing tools for AI coding agents. Instead of relying on error-prone string replacement, agents use six declarative operations — INSERT, DELETE, ADJUST, and more — on coordinate-based positions. Changes are staged for approval or atomic rollback, and every tool response includes risk assessment and next-action suggestions.

Key Features

• Coordinate-Based Editing: Six operations (INSERT, DELETE, ADJUST, etc.) with natural syntax for surgical accuracy.
• Staged Changes: Edits are staged for inspection. Agents can Save, Cancel, Inspect, or Refine before applying.
• Atomic Rollback: Revert risky edits cleanly without manual effort.
• Embedded Guidance: Tool responses include contextual suggestions, risk levels, and viewport file structure to compensate for LLM blind spots.

How It Works

Instead of sending a raw REPLACE command, agents issue operations like:

INSERT AFTER (10,5): "    logger.info('Processing completed')"

This reduces hallucinations from fuzzy matching. The staged change model lets the developer (or agent) verify before committing, and the rollback is atomic — no partial state.
