/opencode — Peer AI via OpenCode CLI

You have access to OpenCode CLI as a peer AI. It supports multiple providers and models (MiniMax, Anthropic, Google, etc.). Use it to brainstorm, delegate tasks, get second opinions, or ask questions from a different AI perspective.

How to invoke

Run the wrapper script via Bash. IMPORTANT: OpenCode can take 3-6 minutes depending on the model and task complexity. You MUST set the Bash tool's timeout parameter to 420000 (7 minutes) to prevent Claude Code from killing the process before OpenCode finishes.

bash "${CLAUDE_PLUGIN_ROOT}/scripts/opencode-run.sh" \
  --prompt "YOUR PROMPT HERE" \
  --cwd "/path/to/relevant/directory" \
  --mode exec

Then read the output file path it prints and present the results to the user.

Step-by-step workflow

1. Parse the user's request. The user says /opencode "some prompt" or /opencode followed by a question.
2. Determine the working directory. Default to the current project root. If the user references a specific repo or directory, use that.
3. Run opencode-run.sh with --mode exec and the user's prompt via the Bash tool.
4. Read the output file using the Read tool. The script prints the output file path to stdout.
5. Show OpenCode's raw response directly. Use this format — show their actual words, don't paraphrase or summarize:

🟢 **OpenCode:**
> [their full response here, verbatim, as a blockquote]

6. Add your own take only if asked. If the user wants a comparison or synthesis, add it after OpenCode's response. Otherwise, let OpenCode's voice stand on its own.

Options

Model configuration

Default (zero config): Uses opencode/minimax-m2.5-free — works without any API key.

Custom model (persistent): Set opencode_model in ~/.claudes-ai-buddies/config.json:

{ "opencode_model": "minimax/MiniMax-M2.5" }

Per-invocation override: Pass --model to the script:

bash "${CLAUDE_PLUGIN_ROOT}/scripts/opencode-run.sh" \
  --prompt "..." --model "minimax/MiniMax-M2.7-highspeed"

List available models: opencode models or opencode models minimax

Example invocations

• /opencode "What's the best way to implement a rate limiter in Go?"
• /opencode "Review this architecture: we have a React frontend calling a FastAPI backend with Redis caching"
• /opencode --model minimax/MiniMax-M2.7 "Write a bash script that finds duplicate files by hash"
• /opencode "Debug this error: TypeError: Cannot read property 'map' of undefined"

Setup for new users

1. Install: brew install opencode
2. (Optional) Configure a provider: opencode providers login -p minimax
3. (Optional) Set default model in ~/.claudes-ai-buddies/config.json

Without steps 2-3, the free opencode/minimax-m2.5-free model is used automatically.

Rules

• Never pass secrets or API keys in the prompt.
• Respect timeouts — if OpenCode times out, tell the user and suggest checking their model with opencode models.
• Frame the output clearly — the user should always know which AI produced which response.
• Don't modify files based on OpenCode's suggestions without user confirmation.
