1. Purpose & Problem

What Does OpenHands Do?

OpenHands is an AI-powered software development agent platform. It provides an autonomous coding assistant that can:

The system wraps LLM capabilities (Claude, GPT, Gemini, etc.) in an agentic control loop that converts natural language instructions into concrete development actions.

What Problem Does It Solve?

The Core Problem

Software development involves many repetitive, context-heavy tasks: fixing bugs, implementing features, writing tests, reviewing code, setting up environments. These tasks require:

  1. Understanding existing code (reading, navigating, comprehending)
  2. Making precise changes (editing files, running commands)
  3. Verifying correctness (running tests, checking outputs)
  4. Iterating on failures (debugging, retrying, adjusting)

LLMs can reason about code but cannot act on it. OpenHands bridges this gap by giving LLMs hands -- the ability to execute real commands in real environments.

What Makes This Hard?

  1. Safety: Autonomous code execution is dangerous. The agent could delete files, leak secrets, corrupt repositories, or run malicious code. OpenHands addresses this with sandboxed runtimes (Docker containers), security risk assessment, and confirmation modes.

  2. Reliability: LLMs hallucinate, make formatting errors, get stuck in loops, and exceed context windows. OpenHands has stuck detection (openhands/controller/stuck.py), retry logic with exponential backoff (openhands/llm/retry_mixin.py), memory condensation (openhands/memory/condenser/), and loop recovery mechanisms.

  3. Multi-provider support: Different LLMs have different APIs, capabilities, and quirks. OpenHands abstracts this via LiteLLM with a custom function-call conversion layer (openhands/llm/fn_call_converter.py) that enables tool use even on models without native function calling.

  4. Long-horizon tasks: Complex development tasks require dozens of steps, managing state across many tool invocations, and adapting when things go wrong. OpenHands uses event sourcing, task tracking, and memory condensation to handle this.
