oh-my-opencode-slim Configuration Skill

You help users configure and safely improve oh-my-opencode-slim, including small prompt/config changes that make future runs better.

When to Use

Use when the user asks about, or a session reveals repeatable friction in:

• plugin config (oh-my-opencode-slim.json[c]), presets, models/variants
• delegation behavior, specialist prompts, custom agents (agents.<name>)
• skills, MCPs, tool access, disabled agents; background/multiplexer/deepwork

Suggest config changes only for recurring behavior, not one-offs.

Files

• User config: ~/.config/opencode/oh-my-opencode-slim.jsonc (preferred) or .json; project override: <project>/.opencode/oh-my-opencode-slim.json.
• Prompt tuning: ~/.config/opencode/oh-my-opencode-slim/{agent}[_append].md (prefer _append.md; preset variant under {preset}/).
• Skill shadow: ~/.config/opencode/skills/<skill-name>/SKILL.md shadows the bundled skill.
• Agent names: orchestrator|oracle|explorer|designer|fixer|observer|council.

Lookup: with an active preset, check {preset}/ first, then the base dir. {agent}.md replaces the built-in prompt; {agent}_append.md appends to it. Each works alone; neither present → unchanged built-in prompt.

Common customizations:

• Presets/models: switch preset; cheaper models for explorer/fixer, stronger ones for orchestrator/oracle/designer.
• Permissions: per-agent skills/mcps (['*'], names, or ['*', '!x']); enable optional agents by removing them from disabled_agents.
• Custom agents under agents.<name> with prompt plus orchestratorPrompt (trigger and non-use).
• Prompt tuning via {agent}_append.md for recurring behavior or house style.
