What problem does it solve? Tuning an oh-my-opencode-slim installation requires knowing which config files, prompt override paths, and schema rules apply, and mistakes can silently change agent behavior or cost. This Skill guides safe, minimal configuration changes to agents, models, prompts, skills, MCPs, and presets. ## Core Features & Use Cases - Agent and model tuning: Adjust models, variants, skills, and MCP permissions per built-in agent within the active preset. - Prompt customization: Append or replace built-in agent prompts via markdown override files with a defined lookup order. - Custom agent creation: Define focused specialist agents with prompt and orchestratorPrompt fields for delegation routing. - Use Case: If the Orchestrator repeatedly spawns overlapping parallel writers, propose a narrow rule in orchestrator_append.md, confirm with the user, apply it, and note the restart requirement. ## Quick Start Ask the assistant to tune your oh-my-opencode-slim config, for example to lower costs by assigning cheaper models to the explorer, librarian, and fixer agents.
