@datum-cloud/opencode-plugins

A port of the datum-cloud/claude-code-plugins Claude Code marketplace to OpenCode. It ships a single npm package containing agents, skills, commands, and one TypeScript hook plugin.

The three source Claude Code plugins are merged flat into one collection:

Pack	Description	Agents	Skills	Commands	Hook
datum-platform	Kubernetes platform engineering (aggregated API servers, controller patterns, GitOps deployment)	7	32	8	auto-validate + pr-op-gate
datum-gtm	Go-to-market automation (commercial strategy, product discovery, customer support)	4	4	1	—
milo-activity	Milo Activity service (audit logs, incidents, policy authoring)	2	7	0	—
total (deduplicated)		13	42	9	1

Installation

Add the package to your OpenCode config's plugin array:

// opencode.json (project) or ~/.config/opencode/opencode.json (global)
{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@datum-cloud/opencode-plugins"]
}

On startup, OpenCode installs the package via Bun and runs postinstall.mjs, which copies the bundled agents/, commands/, and skills/ markdown into ~/.config/opencode/ (idempotent — existing files are never overwritten). The auto-validate TypeScript hook is loaded via the plugin entry point. Restart OpenCode and the agents/skills/commands are discovered automatically.

Prerequisites

• milo-activity skills expect the activity binary on your PATH and configured as an MCP server separately.
• The datum-platform auto-validate hook invokes the per-skill scripts/*.sh validators; these ship under skills/<skill>/scripts/ and run via your shell.

Agents

datum-platform (7)

api-dev, code-reviewer, frontend-dev, operational-reviewer, sre, tech-writer, test-engineer.

The source datum-platform/agents/plan.md is intentionally not ported — OpenCode ships a built-in primary plan agent. All ported agents are mode: subagent and omit model (they inherit the user's configured model).

datum-gtm (4)

commercial-strategist, gtm-comms, product-discovery, support-triage.

milo-activity (2)

incident-investigator (read-only investigation), policy-author (interactive policy creation).

Commands

All commands are namespaced to avoid collisions across packs (discover exists in both datum-platform and datum-gtm):

platform-corrections, platform-deploy, platform-discover, platform-evolve, platform-patterns, platform-pipeline, platform-review, platform-trends, gtm-discover.

Validation

npm run typecheck        # tsc --noEmit on the TS hook
OPENCODE_CONFIG_DIR=/tmp/oc-test node postinstall.mjs   # dry-run install
