@sebastiangrebe/opencode-plugin

Tandemu AI Teammate plugin for OpenCode. Adds the same task lifecycle, telemetry, persistent memory, and personality system that Tandemu provides to Claude Code, but native to OpenCode.

Install

# 1. Make sure you have a Tandemu account and configure auth:
./install.sh --target=opencode

# 2. Add the plugin to opencode.json (install.sh does this automatically):
{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@sebastiangrebe/opencode-plugin"]
}

OpenCode auto-installs the plugin via Bun on startup.

What it provides

• Slash commands: /morning, /finish, /pause, /create, /standup, /setup
• Skills at ~/.config/opencode/skills/ — same SKILL.md content as the Claude Code plugin
• Personality: ~/.config/opencode/AGENTS.md is kept in sync with personality memories from the Tandemu API
• Telemetry: emits opencode.cost.usage, opencode.token.usage, opencode.lines_of_code.count, opencode.tool.usage via OTLP/HTTP to the Tandemu backend
• Memory MCP: configures tandemu-memory MCP server in opencode.json so the agent can search and store memories

Hooks

| Event | What it does | |---|---| | session.created | Pulls personality memories from the API and updates the personality block in AGENTS.md | | session.idle / session.compacted | Computes lines-of-code from git diff --numstat and flushes the OTLP buffer | | tool.execute.after | Records opencode.tool.usage and opencode.tool.duration | | message.updated | Records opencode.cost.usage and opencode.token.usage from the message's cost/token fields | | shell.env | Injects TANDEMU_TOKEN, TANDEMU_API, etc. so skill bodies' curl commands authenticate without re-reading config |

Config

Reads ~/.config/tandemu/auth.json (written by install.sh --target=opencode or /tandemu:setup):

{
  "auth": { "token": "..." },
  "api": { "url": "https://api.tandemu.dev" },
  "organization": { "id": "...", "name": "..." },
  "user": { "id": "...", "email": "...", "name": "..." },
  "teams": [{ "id": "...", "name": "..." }]
}

Override paths with env vars: TANDEMU_HOME, TANDEMU_STATE, TANDEMU_OTEL_ENDPOINT, OPENCODE_AGENTS_MD.

Versioning

Version mirrors the Claude Code plugin (apps/claude-plugins/.claude-plugin/plugin.json). pnpm release bumps both.
