What problem does it solve? Tuning an oh-my-opencode-slim setup involves scattered JSON/JSONC config files, preset structures, and markdown prompt override files, making it easy to apply changes in the wrong place or break existing settings. This Skill guides safe, minimal configuration edits so agent behavior improves without clobbering user customizations. ## Core Features & Use Cases - Agent and model tuning: Adjust models, variants, skills, and MCP permissions per built-in agent (orchestrator, oracle, librarian, explorer, designer, fixer, observer, council) within presets. - Prompt customization: Append or replace built-in agent prompts via markdown override files, with preset-specific variants and a defined lookup order. - Custom agent creation: Define focused specialist agents under agents.<name> with prompt and orchestratorPrompt for Orchestrator routing. - Use Case: If the Orchestrator repeatedly spawns overlapping parallel writers, the Skill proposes a narrow rule in orchestrator_append.md, asks for confirmation, applies it, and notes the restart requirement. ## Quick Start Ask the assistant to review your oh-my-opencode-slim config and propose a cheaper model assignment for the explorer and librarian agents.
