OpenCode Delegation

Overview

OpenCode is an open-source, provider-agnostic terminal agent published as npm opencode-ai. Its scripting entry point is opencode run, which takes the prompt as positional arguments.

Being provider-agnostic makes it the most flexible entry in the registry: the model behind it is whatever the local OpenCode config selects, including a local one.

When To Use

• delegation-core selected opencode for the task
• A provider the registry does not model directly is wanted, and OpenCode already has it configured
• A local or self-hosted model should serve the request

When NOT To Use

• No provider credentials are configured. opencode auth list shows what is present
• A specific model must be pinned from this side. Model choice belongs to OpenCode's own config, not to the delegation call

Prerequisites

Installation

npm install -g opencode-ai@latest

Homebrew, pnpm, bun, scoop and chocolatey are also documented upstream.

Authentication

Credentials resolve per provider through environment variables such as ANTHROPIC_API_KEY or OPENAI_API_KEY, through a .env file, or through opencode auth login. Stored credentials are written to ~/.local/share/opencode/auth.json, and the config file supports {env:VARIABLE_NAME} interpolation.

Verification runs opencode auth list, because there is no single variable to check when the provider set is open-ended.

Quick Start

Using the shared delegation executor

uv run python scripts/delegation_executor.py opencode "Find the bug" \
  --files src/

Through the Makefile

make -C plugins/conjure delegate-opencode PROMPT='Find the bug'

Direct CLI usage

opencode run "Explain the use of context in this package"

Smart Delegation

opencode declares the code_execution strength and ranks last among the network providers in the candidate order, ahead only of the local glimmer service. It declares no model ids, since model choice belongs to OpenCode's own configuration.

OpenCode-Specific Details

Property	Value
Binary	opencode
Package	opencode-ai
Headless form	opencode run <prompt>
Prompt delivery	positional
Version probe	opencode --version
Auth probe	opencode auth list

opencode run --file <path> attaches a file upstream, but this service inlines file context into the prompt instead, which keeps one delivery path across every provider that lacks an @path syntax.

opencode serve starts a headless HTTP server that opencode run --attach <url> can target, and it honors OPENCODE_SERVER_PASSWORD. That path is not modeled here: the registry spawns a process per delegation rather than holding a server.

An output-format flag is documented for the session list, export and db subcommands, but not confirmed for run, so none is declared.

Exit Criteria

• opencode resolves on PATH and answers opencode --version
• opencode auth list shows at least one configured provider
• The built command is opencode run <prompt> with the prompt last and no prompt flag before it
• File context was inlined into the prompt rather than passed with --file
• Output saved to delegations/opencode/YYYYMMDD_HHMMSS.md
• This skill ran because delegation-core selected opencode
