setup

A setup command that checks whether the OpenCode command-line tool is installed and configured, and can enable or disable a review check at the end of work.

In plain words
What is it for?
Use it when setting up OpenCode locally or checking its readiness before using related commands.
Why use it?
It shows whether OpenCode is ready and explains what to do if it is missing or has no login provider configured.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 283 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

setup scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/opencode-companion.mjs" setup --json $ARGUMENTS

If the result says OpenCode is unavailable:

  • Use AskUserQuestion exactly once to ask whether Claude should install OpenCode now.
  • Put the install option first and suffix it with (Recommended).
  • Use these two options:
    • Install OpenCode (Recommended)
    • Skip for now
  • If the user chooses install, run:
npm install -g opencode-ai
  • Then rerun:
node "${CLAUDE_PLUGIN_ROOT}/scripts/opencode-companion.mjs" setup --json $ARGUMENTS

If OpenCode is already installed:

  • Do not ask about installation.

Output rules:

  • Present the final setup output to the user.
  • If installation was skipped, present the original setup output.
  • If OpenCode is installed but no provider is configured, guide the user to run !opencode providers to set up authentication.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
