Summary Orca is a Rust-based, DeepSeek-native coding agent for local terminal use. It addresses complex coding tasks via a multi-turn agent loop, featuring SSE streaming, automatic context management, and robust HTTP retry mechanisms, enabling efficient AI-assisted development directly in the command line.

How It Works The agent operates on a multi-turn loop: prompt -> model -> tool_call -> execution -> result -> next turn. It leverages DeepSeek's 1M token context (V4) with intelligent 80% threshold compaction. Core functionalities are in Rust for performance, SSE streaming provides real-time feedback, and HTTP requests include exponential backoff retry logic for reliability.

Quick Start & Requirements Installation is via npm (npm install -g @blade-ai/orca) or curl script (curl -fsSL https://orcaagent.dev/install.sh | sh). Manual installation involves downloading binaries from GitHub Releases. A DEEPSEEK_API_KEY environment variable is mandatory. Supported platforms: macOS (Apple Silicon/Intel), Linux (x64/ARM64).

Highlighted Details

• Interactive TUI: Compact terminal UI with semantic color-coding for permission modes.
• Context Management: DeepSeek V4's 1M token context with 80% threshold compaction.
• Extensive Tooling: Built-in tools for file operations, code analysis, shell commands, Git, web search, subagents, and dynamic workflows. Custom tools via TOML.
• Persistent Goals: TUI sessions support persistent goals with /goal commands, enabling auto-continuation and state persistence.
• Structured Output: JSONL format for event streaming (session lifecycle, reasoning, tool calls, approvals).

Licensing & Compatibility The project's open-source license is not stated in the README, requiring further investigation for commercial use. Compatibility is primarily with supported npm platforms (macOS, Linux) and necessitates a DeepSeek API key.

Limitations & Caveats The unspecified license is a significant adoption blocker. While described as "production-ready," specific performance benchmarks are absent. The agent relies heavily on the DeepSeek API, tying its functionality to that service's availability and terms.
