​
Overview

OpenCode is a supported platform for Understand Anything. Installation is done by adding one line to your opencode.json config file — OpenCode then fetches and installs the plugin automatically on next startup.

​
Prerequisites

  • OpenCode installed
  • A project directory with an opencode.json, or a global opencode.json in your home directory

​
Installation

1

Add the plugin to opencode.json

Open your opencode.json (project-level or global) and add understand-anything to the plugin array:
{
  "plugin": ["understand-anything@git+https://github.com/Lum1104/Understand-Anything.git"]
}
If you already have other plugins listed, append to the existing array:
{
  "plugin": [
    "some-other-plugin",
    "understand-anything@git+https://github.com/Lum1104/Understand-Anything.git"
  ]
}
2

Restart OpenCode

Restart OpenCode. The plugin is fetched from GitHub and all skills are registered automatically.

​
Verification

After restarting, ask OpenCode: 
List available skills
You should see understand, understand-chat, understand-dashboard, and other understand-* skills in the response. You can also verify the plugin files were cached: 
ls ~/.cache/opencode/node_modules/understand-anything

​
First Use

Use the skill tool to run the analysis: 
use skill tool to load understand-anything/understand
Or simply ask: 
Analyze this codebase and build a knowledge graph

​
Pinning a Specific Version

To lock to a particular release instead of tracking main: 
{
  "plugin": ["understand-anything@git+https://github.com/Lum1104/Understand-Anything.git#v1.1.1"]
}

​
Updating

Restart OpenCode — the plugin re-installs from git automatically, pulling the latest commit on main (or the pinned tag if specified).

​
Uninstalling

Remove the plugin line from opencode.json and restart OpenCode.

​
Troubleshooting

​
Skills not found after restart

  1. Verify the plugin line is present and correctly formatted in your opencode.json.
  2. Check that the cache directory was populated: 
    ls ~/.cache/opencode/node_modules/understand-anything
  3. Use the skill tool inside OpenCode to list all discovered skills and confirm they are registered.

​
Tool name mapping

When skills reference Claude Code tool names, OpenCode maps them as follows:
Claude Code toolOpenCode equivalent
TodoWritetodowrite
Task with subagents@mention syntax
Skill toolOpenCode’s native skill tool
File operationsYour native file tools
