Gorc

An opencode plugin that ships a conductor primary agent plus a fleet of cheap subagents — go-research, go-reader, go-implementer, go-qa — and the orchestration logic to gate and observe delegations.

The conductor plans, reasons, and delegates the grinding to budget models. You stay in the expensive model's context for the thinking; the fleet does the trawling, reading, and bulk editing.

Install

Published to npm as @balatd/gorc. opencode auto-installs it on startup:

// opencode.jsonc
{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@balatd/gorc"]
}

To make the conductor your default agent:

"plugin": [["@balatd/gorc", { "defaultAgent": "conductor" }]]

The fleet

Agent	Mode	Use for
conductor	primary	Plans, reasons, delegates. The only agent that may call task.
go-research	subagent	websearch + webfetch + read-only exploration of unfamiliar code.
go-reader	subagent	Targeted reads of code whose location is already known.
go-implementer	subagent	Applies planned edits and mechanical refactors across files.
go-qa	subagent	Read-only testability check on what the implementer just wrote.

The conductor's task permission is force-gated to the four subagents — it cannot delegate to anything else, even if you override the conductor in your own config.

Models

By default every agent targets the opencode-go provider:

Agent	Default model
conductor	opencode-go/glm-5.2
go-research	opencode-go/deepseek-v4-flash
go-reader	opencode-go/mimo-v2.5
go-implementer	opencode-go/deepseek-v4-pro
go-qa	opencode-go/deepseek-v4-flash

If you don't have that provider, point the fleet at your own models via options — any field you omit keeps its default:

"plugin": [[
  "@balatd/gorc",
  {
    "conductorModel": "anthropic/claude-sonnet-4-6",
    "researchModel": "anthropic/claude-haiku-4-5",
    "readerModel": "anthropic/claude-haiku-4-5",
    "implementerModel": "anthropic/claude-sonnet-4-6",
    "qaModel": "anthropic/claude-haiku-4-5",
    "defaultAgent": "conductor"
  }
]]

Options

Option	Default	Effect
conductorModel	opencode-go/glm-5.2	Model for the conductor.
researchModel	opencode-go/deepseek-v4-flash	Model for go-research.
readerModel	opencode-go/mimo-v2.5	Model for go-reader.
implementerModel	opencode-go/deepseek-v4-pro	Model for go-implementer.
qaModel	opencode-go/deepseek-v4-flash	Model for go-qa.
defaultAgent	(unset)	If set (e.g. "conductor") and you have no default_agent already, sets it.
logDelegations	true	Log every task delegation to the opencode log stream.

Overriding agents

Anything you define under "agent" in your own config wins — the plugin only injects agents you haven't already defined. So to tweak a prompt or permission, define that agent yourself and the plugin leaves it alone (the conductor's task gating is still force-stamped, by design).

The test command

Ships a /test command that invokes go-qa on your most recently edited paths (or a path you pass it):

/test src/foo.ts

How it works

A single opencode plugin (src/index.ts) uses the config(cfg) hook to inject the five agents and the test command into your merged config, reads each agent's prompt body from the bundled agents/*.md files at runtime, and force-stamps the conductor's task permission so the fleet boundary can't be widened by accident. A tool.execute.before hook logs every delegation.

Develop

bun install
bun run build        # -> dist/index.js
