What are skills in Oh My Opencode Slim?

Skills are prompt-based instructions injected into an agent's system prompt to guide decisions, workflows, and tool use. Unlike MCP servers, they run no process — each skill is a focused playbook an agent activates when the task calls for it. Oh My Opencode Slim bundles 8 skills, installed and kept up to date by the installer.

Codemap skill artifact: a golden scroll-map with a glowing constellation of directory nodes connected by circuit-trace paths

Codemap

orchestrator

Repository Cartography

Generates hierarchical codemap.md files that document the why and how of each directory, so agents understand unfamiliar codebases without re-reading thousands of lines of code on every task.

Deepwork skill artifact: an ornate arcane hourglass with molten golden sand, ringed by orbiting runic phase markers

Deepwork

orchestrator

Heavy Session Workflow

A workflow for large, high-risk, multi-phase coding efforts with meaningful dependencies and review gates. Reserved for the sessions that are too big to wing.

Full docs
Verification Planning skill artifact: a golden balance scale weighing two glowing runic evidence orbs on a circuit-etched pedestal

Verification Planning

orchestrator

Evidence Before Code

Designs a credible, project-specific evidence path before non-trivial implementation work — features, bug fixes, refactors, and cross-system changes get a verification plan first.

Simplify skill artifact: a ceremonial golden chisel carving excess away from a glowing crystalline block

Simplify

oracle

Behavior-Preserving Refactors

Simplifies code for clarity without changing behavior. Focused on readability, maintainability, and complexity reduction once the existing behavior is understood.

Full docs
Worktrees skill artifact: a golden tree whose branches grow in parallel protective crystal channels

Worktrees

orchestrator

Isolated Coding Lanes

Manages Git worktrees as safe, isolated coding lanes — so complex, risky, or parallel work never contaminates your main checkout.

Full docs
Clonedeps skill artifact: an ornate magnifying lens over an ancient tome revealing glowing clockwork mechanisms inside

Clonedeps

orchestrator

Dependency X-Ray

Clones important dependency source code into an ignored local workspace, letting agents inspect library and SDK internals instead of guessing from documentation.

Full docs
Reflect skill artifact: an obsidian hand mirror reflecting a golden spiral, orbited by glowing memory orbs

Reflect

orchestrator

Workflow Self-Improvement

Reviews recent work for repeated patterns and suggests reusable skills, agents, commands, config changes, or playbooks — turning recurring friction into permanent improvements.

Oh My Opencode Slim skill artifact: a golden astrolabe with adjustable rings caught mid-motion, reconfiguring itself

Oh My Opencode Slim

orchestrator

Plugin Self-Configuration

Configures and safely improves the plugin itself — tuning agents, models, prompts, custom agents, skills, MCPs, and presets for the current user.

Which agent uses each skill?

The Orchestrator holds most skills by default; review-oriented skills belong to Oracle. Assignments are permission grants — an agent can only activate skills it has been given.

Can I customize which skills my agents use?

Yes. Skill assignments are configurable per agent in ~/.config/opencode/oh-my-opencode-slim.json — grant an explicit skill list, allow everything with *, or deny individual skills with a !skill-name entry.
