Cursor features
- Agentic coding. AI agents can generate, edit, and test code based on high-level prompts.
- Multi-surface support. Works in a desktop IDE, terminal CLI, Slack, GitHub, Linear and more.
- Cloud agents. Launch fleets of autonomous agents that run in parallel on cloud resources.
- Mission Control UI. Grid view of open windows for quick navigation and window management.
- Team rules & privacy. Define team conventions, enable privacy mode to prevent data training.
- Model selection. Choose from OpenAI, Anthropic, Gemini, SpaceXAI and Cursor models per task.
OptScale Kompressor features
- Deterministic rule-based compression. Same input always yields identical compressed bytes, preserving prompt-cache discounts.
- Labelled, retrievable elisions. Removed sections are replaced with markers that can be fetched back within an hour.
- Format-specific compressors. Handles build logs, compiler diagnostics, JSON, diffs, source code, and more with custom rules.
- Fails-open safety. A result that isn’t smaller than the input is discarded, and on any error the request passes through unchanged.
- Single Rust binary. One static binary, about 0.2 ms per KB of tool output, with pre-built releases for Linux and macOS.
- Works with your coding agent. Built for Codex and Claude Code; kompressor wrap also supports opencode, aider and Cursor (own OpenAI key). On Claude Code it keeps the cache warm while tools run.
