add-opencode

add-opencode is a skill for Claude Code, Codex from thmtz/nanoclaw-fleet. It costs 67 tokens per session (2,733 once invoked), scanned A, a copy of add-opencode, MIT.

A skill that adds OpenCode as an alternative agent provider for NanoClaw. OpenCode can use providers such as OpenRouter, OpenAI, Google, and DeepSeek through its configuration.

In plain words
What is it for?
Use it to install and wire the OpenCode provider, configure the selected backend, pass required environment settings, and rebuild the container image.
Why use it?
It lets NanoClaw choose OpenCode instead of its built-in Claude provider for agent sessions or groups.

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

add-opencode scanned grade A with 0 findings 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

86% identical to add-opencode — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenCode agent provider

NanoClaw runs agents in a long-lived poll loop inside the container. The backend is selected with AGENT_PROVIDER (claude | opencode | mock).

Trunk ships with only the claude provider baked in. This skill copies the OpenCode provider files in from the providers branch, wires them into the host and container barrels, installs dependencies, and rebuilds the image.

Install

Pre-flight

If all of the following are already present, skip to Configuration:

  • src/providers/opencode.ts
  • container/agent-runner/src/providers/opencode.ts
  • import './opencode.js'; line in src/providers/index.ts
  • import './opencode.js'; line in container/agent-runner/src/providers/index.ts
  • @opencode-ai/sdk in container/agent-runner/package.json
  • opencode-ai@${OPENCODE_VERSION} in the pnpm global-install block in container/Dockerfile

Missing pieces — continue below. All steps are idempotent; re-running is safe.

1. Fetch the providers branch

git fetch origin providers

2. Copy the OpenCode source files

Wholesale copies (owned entirely by this skill — user edits to these files won't survive a re-run, as designed):

git show origin/providers:src/providers/opencode.ts                                    > src/providers/opencode.ts
git show origin/providers:container/agent-runner/src/providers/opencode.ts             > container/agent-runner/src/providers/opencode.ts
git show origin/providers:container/agent-runner/src/providers/mcp-to-opencode.ts      > container/agent-runner/src/providers/mcp-to-opencode.ts
git show origin/providers:container/agent-runner/src/providers/mcp-to-opencode.test.ts > container/agent-runner/src/providers/mcp-to-opencode.test.ts
git show origin/providers:container/agent-runner/src/providers/opencode.factory.test.ts > container/agent-runner/src/providers/opencode.factory.test.ts

3. Append the self-registration imports

Each barrel gets one line appended at the end — skip if the line is already present.

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.
