OpenCode Orchestrator

Multi-agent mission control for OpenCode.

Version: 1.3.6

1. Install

npm install -g opencode-orchestrator

The install hook merges OpenCode config instead of replacing it, prefers opencode.jsonc when present, preserves existing plugin tuple options, and skips automatic config mutation in CI.

To remove the plugin from OpenCode config:

npm explore -g opencode-orchestrator -- npm run cleanup:plugin
npm uninstall -g opencode-orchestrator

Manual fallback: remove "opencode-orchestrator" or ["opencode-orchestrator", {...}] from the plugin array in opencode.json or opencode.jsonc.

2. Configure

OpenCode supports plugin options as ["plugin-name", {...}] tuples. Use that form for orchestrator-specific settings:

{
  "$schema": "https://opencode.ai/config.json",
  "permission": {
    "question": "allow"
  },
  "plugin": [
    [
      "opencode-orchestrator",
      {
        "agentConcurrency": {
          "commander": 1,
          "planner": 10,
          "worker": 10,
          "reviewer": 10
        },
        "missionLoop": {
          "ledger": true,
          "markdownMemory": true,
          "maxEvidenceEvents": 20
        }
      }
    ]
  ]
}

Optional model routing stays in normal OpenCode config. The plugin does not force a model:

{
  "model": "provider/model-id",
  "agent": {
    "commander": {
      "model": "provider/model-id"
    },
    "worker": {
      "model": "provider/stronger-model-id"
    }
  }
}

Generated Commander, Planner, Worker, and Reviewer agents inherit global permissions. Same-name user agent config can still override specific model or permission keys.

3. Run

Inside OpenCode:

/task "Implement the requested change and verify it"

Mission controls:

/task ... starts a persisted mission loop under .opencode/.
Esc/OpenCode interrupt is respected by idle guards so the plugin does not immediately re-continue an interrupted turn.
/cancel and /stop deactivate the current mission loop.
The default mission iteration ceiling is 1,000,000,000.

4. How It Works

flowchart LR
  U["/task input"] --> C["Commander"]
  C --> P["Planner"]
  C --> W["Worker pool"]
  W --> R["Reviewer"]
  P --> S["Mission state"]
  W --> S
  R --> V{"Verified?"}
  V -- "no" --> C
  V -- "yes" --> D["Done"]

Agent	Purpose
Commander	Interprets the mission, coordinates agents, and keeps the loop aligned.
Planner	Breaks work into ordered steps and tracks dependencies.
Worker	Implements scoped file changes with isolated context.
Reviewer	Checks completion evidence, tests, and integration risk.

Runtime evidence is written only when enabled:

Artifact	Purpose
`.opencode/mission-ledger.jsonl`	Bounded event trail for mission decisions.
`.opencode/docs/brain/scratchpad.md`	Generated Markdown memory surface for active missions.
`.opencode/docs/brain/knowledge-map.canvas`	Obsidian-compatible visual map of objective, evidence, and verification nodes.
