oh-my-opencode-slim is an agent orchestration plugin for OpenCode that routes coding tasks to specialized agents based on their strengths.
The tool addresses the inefficiency of forcing a single model to handle all aspects of a coding project. Instead, it distributes work across seven specialized agents: an Orchestrator that plans the work graph, an Explorer that scouts codebases, an Oracle that looks up documentation, a Council that synthesizes multiple model perspectives, a Librarian that manages information, a Designer that handles UI work, and a Fixer that executes implementation tasks. The Orchestrator dispatches these specialists as background tasks running in parallel, then reconciles their results before proceeding. This approach allows developers to mix any models across any providers and balance quality, speed, and cost by matching each subtask to the agent best equipped for it.
Adoption makes sense for teams working on substantial codebases where different phases of development benefit from different capabilities. The tool suits projects where parallel agent work can accelerate progress and where cost optimization matters. The plugin includes bundled skills like deepwork, codemap, verification-planning, and reflect that are assigned per agent. It offers a Council mode to run multiple models in parallel on the same question and synthesize results, a Companion window showing active agents, and integration with terminal multiplexers like Tmux, Zellij, and Herdr. Preset switching allows swapping the entire team's models at runtime, and code intelligence tools include LSP support, AST-aware search across 25 languages, and built-in MCPs for documentation and GitHub code search. The system is fully customizable through custom agents, prompt overrides, per-agent skill and MCP permissions, and project-local configuration.
The project maintains active development with regular updates to its documentation and feature set. The team provides multiple language translations of the README and maintains communication channels including a website, social media presence, and community Telegram channel. The codebase is written in TypeScript and includes comprehensive documentation covering background orchestration, Council functionality, multiplexer integration, preset switching, tools, and configuration options.
