Screenshots

The plugin renders agent categories and details inside the OpenCode terminal UI sidebar.

Summary

• Displays OpenCode agents in the OpenCode sidebar.
• Reads agents from oh-my-openagent.json through a normalized provider boundary; the seam permits a future native OpenCode source without claiming universal discovery today.
• Groups agents into neutral categories such as primary, subagents, built-in, project, global, custom, disabled, hidden, and other.
• Supports collapsible category sections and a collapsible main sidebar panel.
• Shows provider, model, variant, fallback, and disabled-agent information according to display settings.
• Supports compact and split row layouts for different terminal widths.
• Supports provider, model, and variant aliases for shorter terminal output.
• Reloads configuration through directory watches with polling recovery and deterministic fingerprint comparison.
• Handles missing or invalid configuration files with explicit sidebar states.

Quick start

opencode plugin add opencode-agents-sidebar@3.0.0

Installation

OpenCode v2

Install the release with the v2 plugin manager:

opencode plugin add opencode-agents-sidebar@3.0.0

The equivalent explicit configuration is:

{
  "$schema": "https://opencode.ai/v2/cli.json",
  "plugins": ["opencode-agents-sidebar@3.0.0"]
}

Add the package once, either to ~/.config/opencode/cli.json or to the v2 plugins field in opencode.json(c). Package order controls v2 sidebar contribution order.

This major does not support OpenCode v1. V1 users must pin opencode-agents-sidebar@1.0.8; there is no dual-runtime compatibility shim.

Local checkout for development

git clone https://github.com/Mark1708/opencode-agents-sidebar.git
cd opencode-agents-sidebar
bun install --frozen-lockfile
bun run build:all
bun run verify:package

The build emits separate v2 server and TUI definitions into dist/; the package verifier writes .artifacts/package.tgz. Repository root shims are intentionally absent.

Configuration

The current release reads one source:

~/.config/opencode/oh-my-openagent.json

Top-level agents, agent_order, disabled_agents, team_mode, and tmux sections are OhMyOpenAgent data. src/providers/omo.ts normalizes that data for the sidebar. The provider seam permits a future native OpenCode source, but native or universal agent discovery is not part of this release.

Smallest useful configuration:

{
  "tui": {
    "sidebar_width": 34,
    "name_width": 18,
    "title": "Agents"
  }
}

Full documented shape:

{
  "tui": {
    "sidebar_width": 34,
    "name_width": 18,
    "poll_interval_ms": 2000,
    "title": "Agents",
    "category_order": ["Primary", "Subagents", "Built-in", "Project", "Global", "Custom", "Disabled", "Hidden", "Other"],
    "model_display": "details-only",
    "show_provider": true,
    "show_variant_in_details": false,
    "show_disabled": "dimmed",
    "agent_row_mode": "compact",
    "symbols": "unicode",
    "provider_aliases": {
      "openai": "oa",
      "opencode": "oc",
      "zai-coding-plan": "zai"
    },
    "model_aliases": {
      "gpt-5.4-mini-fast": "gpt-5.4mf",
      "gpt-5.4-mini": "gpt-5.4m",
      "gpt-5.5": "5.5",
      "glm-4.5-air": "glm-4.5a"
    },
    "variant_aliases": {
      "medium": "M",
      "high": "H",
      "xhigh": "XH"
    }
  }
}

When using the current OhMyOpenAgent bootstrap source, keep a legacy category order if you want the familiar grouping:

{
  "tui": {
    "title": "Agents",
    "category_order": ["Orchestration", "Research", "Architecture", "Review", "Engineering", "Operations", "Analytics", "Consulting", "Other"]
  }
}

Supported values:

• model_display: "inline", "details-only", or "hidden".
• show_disabled: "hidden", "dimmed", or "grouped".
• agent_row_mode: "compact" or "split".
• symbols: "unicode" or "ascii".

OpenCode v2 sidebar contribution order follows package order in the host plugins list.

Usage

• Start OpenCode with the plugin installed.
• The sidebar appears on the right side of the TUI.
• Click the main header to collapse or expand the full sidebar.
• Click category headers to collapse or expand provider groups.
• Click an agent row to show model, variant, and fallback details.
• Tune width, model display, aliases, and symbol mode in provider metadata/config.

Agent categories

The default product categories are neutral OpenCode/provider categories from src/defaults.ts:

Category	Examples
Primary	Main OpenCode agents when the native provider lands
Subagents	OpenCode subagents when the native provider lands
Built-in	Built-in host agents
Project	Project-local agents
Global	User-level agents
Custom	Custom provider agents
Disabled	Disabled agents when grouped
Hidden	Reserved for providers that expose hidden entries
Other	Agents not mapped to a known category

The temporary OhMyOpenAgent bootstrap provider keeps its legacy lifecycle mapping inside src/providers/omo.ts so it does not become the generic product model.

Display options

By default, the sidebar uses agent_row_mode: "compact" with model_display: "details-only". That means the agent list stays focused on names, while the selected agent shows model details below the row.

The runtime display includes the main header, optional team status line, expanded or collapsed categories, details-only agent rows, and selected agent details:

▼ Agents (33 active)
team 2/4
▼ Custom (5)
› local-helper
    mode primary
    source custom
    1°   zai-coding-plan/glm-5.1
    fb   openai/gpt-5.5
    fb   opencode/big-pickle
  reviewer
  planner
▶ Other (3)

• agent_row_mode: "compact" keeps each agent on one row. "split" uses two rows when model_display is "inline".
• model_display: "details-only" shows provider and model details only for the selected agent. "inline" shows model information in the agent row. "hidden" hides model information from rows and details.

Troubleshooting

• If the package does not load, run opencode plugin check and verify that opencode-agents-sidebar@3.0.0 appears once in the v2 plugins list.
• If a local build does not load, run bun run build:all && bun run verify:package and test .artifacts/package.tgz through a disposable v2 wrapper.
• If agents do not appear, verify ~/.config/opencode/oh-my-openagent.json contains valid agent metadata.
• Missing and malformed configuration produce explicit sidebar states and recover after create, replace, or edit.
• If content is cut off, adjust sidebar_width, name_width, or agent_row_mode.
• If model names are too long, use model_aliases, provider_aliases, or variant_aliases.
• If config changes do not appear, verify the configured path is readable; native directory watching falls back to polling after watch errors.

Limitations / Security

• The plugin reads local OhMyOpenAgent metadata, not provider credentials. Native OpenCode agent discovery is a future provider implementation.
• Config reload uses directory watchers with polling recovery, deterministic fingerprints, and generation-gated serialized reads.
• Sidebar width behavior is constrained by terminal and OpenCode TUI rendering.
• Styling depends on the host OpenCode and OpenTUI theme capabilities.
• Example configuration values are placeholders and can be adjusted per local setup.
