What it does
Opencode Delegation is an agent skill from athola/claude-night-market. Delegates tasks to OpenCode (opencode run) via delegation-core. Use when delegation-core selects OpenCode or a provider-agnostic harness is wanted.
Its SKILL.md is about 1000 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: 23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context… The licence is MIT.
When your agent uses it
- Delegation-core selects OpenCode
- A provider-agnostic harness is wanted
Example prompts
- “Use the opencode-delegation skill to delegate tasks to OpenCode (opencode run) via delegation-core”
- “/opencode-delegation”
Requirements
- Python 3
- Node.js
- A credential in ANTHROPIC_API_KEY
- A credential in OPENAI_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 9f3eb00. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
opencodenpmuvmake
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ANTHROPIC_API_KEYOPENAI_API_KEYOPENCODE_SERVER_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Opencode Delegation loads about 999 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 415 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety

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-coreselectedopencodefor 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 listshows 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@latestHomebrew, 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.
