opencode-plugin-manager

An OpenCode sidebar section listing plugins with installed/uninstalled status — placed below the built-in MCP section and the Skills list, mirroring the built-in sidebar widgets.

What it shows

• Installed plugins from the plugin registry (same list opencode2 plugin list shows; built-ins excluded) with their activation state: ✓ active, ✗ failed, ○ inactive.
• LOCAL group mixes registered plugins (✓ … installed) with workspace plugin projects discovered by scanning the workspace root for sibling directories whose package.json depends on @opencode-ai/plugin (private monorepo roots and shared libraries excluded) — those show dimmed with ○ … uninstalled and a [+] to register them, same status column as everything else.
• Built-in plugins are listed by default (group collapsed to keep the sidebar short) and can be hidden/shown with /plugins-builtins — a view toggle only, persisted; built-ins always run. They can't be disabled individually: the runtime has no per-built-in disable mechanism — the only switch is the all-or-nothing OPENCODE_DISABLE_DEFAULT_PLUGINS env var, whose state the widget shows when the BUILT-IN group is visible. Per-built-in disable requires upstream support in OpenCode's plugin host.
• Plugin descriptions — the registry exposes no human metadata, so the plugin ships its own catalog (builtins.ts): curated descriptions for well-known built-ins plus per-category generation (provider.*, tool.*, config.*, websearch.*). Click any row to inspect its details.

Collapsed header shows PLUGINS (installed/total); more than two entries collapse, click (or expand) to list them — same interaction as the built-in MCP/Skills sections.

Install

# in opencode.jsonc
{ "plugins": ["./opencode-usage-quota-tracker", "./opencode-skill-lister", "./opencode-plugin-manager", "./opencode-model-recommender"] }

Order matters: plugins sharing the sidebar.content slot render in plugins array order — keep this entry after opencode-skill-lister (and before anything you want below it) so the section sits directly under MCP and Skills.

Data sources

• Plugin registry: client.plugin.list() (activation state included)
• Workspace scan: sibling directories of the current location, one package.json read per candidate; result is cached through opencode-plugin-kit's createCachedStore so the sidebar restores instantly after a TUI restart.
