OpenCode is a terminal-based development agent that automates software engineering tasks by integrating artificial intelligence directly into the command-line environment. It functions as an autonomous workflow orchestrator, capable of executing file operations, running shell commands, and applying code patches to complete complex development tasks without manual intervention.
The tool distinguishes itself through its ability to index local codebases into vector embeddings, enabling semantic search and natural language queries across project files. It maintains session context through a local database that stores and summarizes interaction history, ensuring that long-running development sessions remain within model token limits. Users can further customize their experience by configuring agent parameters and switching between various commercial or self-hosted intelligence backends.
Beyond its core agentic capabilities, the project provides utilities for schema-driven type generation, which inspects database definitions to produce type-safe interfaces. It also supports the definition of custom commands to streamline repetitive terminal workflows and integrates with external development tools through standardized messaging protocols.
