subagent-fleet

Run Claude Code-style subagents across your local model fleet.

subagent-fleet is a config-first Python CLI for mapping coding subagents to the best Ollama model and machine you own, then generating LiteLLM and Claude Code-style agent configuration.

Overview

Local model users often have more than one useful machine: a laptop, a Mac mini, a workstation, a home server, or a spare GPU box. Most coding harnesses still point at one model endpoint.

subagent-fleet turns that setup into a private local subagent fleet:

planner     -> small fast model on a lightweight node
implementer -> larger coding model on a bigger node
reviewer    -> larger coding model on a bigger node
summarizer  -> small local model on the controller

It does not replace Ollama, LiteLLM, or Claude Code. It generates the glue between them:

Claude Code / coding harness
        |
        v
LiteLLM gateway generated by subagent-fleet
        |
        +-- Ollama node: laptop
        +-- Ollama node: Mac mini 64GB
        +-- Ollama node: workstation

Features

  • Validate a declarative fleet.yaml.
  • Discover models from configured Ollama nodes via /api/tags.
  • Generate litellm_config.yaml with ollama_chat/ routes.
  • Generate Claude Code-style .claude/agents/*.md files.
  • Generate .env.subagent-fleet for Claude Code/LiteLLM environment variables.
  • Warm configured Ollama models with keep_alive.
  • Show node health and agent routing tables.
  • Keep unreachable nodes isolated so one offline machine does not crash the whole workflow.

Status

MVP CLI implemented.

Available commands:

subagent-fleet init
subagent-fleet validate
subagent-fleet discover
subagent-fleet generate
subagent-fleet warmup
subagent-fleet status
subagent-fleet doctor
subagent-fleet clean
subagent-fleet skills list

Install

Choose one of the install paths below.

CLI from GitHub

Install the CLI directly from PyPI:

python -m pip install subagent-fleet

Or install it as an isolated command with pipx:

pipx install subagent-fleet

Verify:

subagent-fleet --help

Development Checkout

Use this when contributing to the project:

git clone https://github.com/adityak74/subagent-fleet.git
cd subagent-fleet
python -m pip install -e ".[dev]"

Run tests:

python -m pytest

Claude Code Plugin First

Install the plugin first from Claude Code, then let the bundled bootstrap skill install the CLI:

/plugin marketplace add https://github.com/adityak74/subagent-fleet
/plugin install subagent-fleet

After install, ask Claude Code:

Use the subagent-fleet bootstrap skill to install the CLI and set up this repo.

The bootstrap skill will run or recommend:

python -m pip install subagent-fleet
subagent-fleet skills install

Codex Plugin First

Install this repository as a local Codex marketplace:

codex plugin marketplace add .
codex plugin add subagent-fleet@subagent-fleet

Then ask Codex:

Use the subagent-fleet bootstrap skill to install the CLI and set up this repo.

Quickstart

Create a starter config:

subagent-fleet init

Edit fleet.yaml with your Ollama node endpoints and model names, then validate it:

subagent-fleet validate

Check which nodes are reachable:

subagent-fleet discover

Generate LiteLLM, Claude agent, and environment files:

subagent-fleet generate

Start LiteLLM:

export LITELLM_MASTER_KEY="sk-local-dev"

litellm \
  --config ./litellm_config.yaml \
  --host 127.0.0.1 \
  --port 4000

Point Claude Code at the local gateway:

source .env.subagent-fleet
claude

Configuration

subagent-fleet is driven by fleet.yaml.

Assistant Skills

subagent-fleet ships assistant-facing skills that teach Claude Code, Codex, OpenCode, and similar tools how to set up and operate the fleet from inside a repository.

List bundled skills and supported targets:

subagent-fleet skills list

Install all bundled skills for all supported targets:

subagent-fleet skills install

This writes:

.claude/skills/subagent-fleet-setup/SKILL.md
.claude/skills/subagent-fleet-operations/SKILL.md
.codex/skills/subagent-fleet-setup/SKILL.md
.codex/skills/subagent-fleet-operations/SKILL.md
.opencode/skills/subagent-fleet-setup/SKILL.md
.opencode/skills/subagent-fleet-operations/SKILL.md

Install for a specific assistant:

subagent-fleet skills install --target codex
subagent-fleet skills install --target claude-code
subagent-fleet skills install --target opencode

Install one bundled skill:

subagent-fleet skills install --skill subagent-fleet-setup

Existing skill files are not overwritten unless you pass --force.

Plugin Marketplaces

This repository also ships plugin marketplace metadata so users can install the assistant skill first, then let that skill install and verify the Python CLI.

Included plugin artifacts:

.claude-plugin/marketplace.json
.agents/plugins/marketplace.json
plugins/subagent-fleet/.claude-plugin/plugin.json
plugins/subagent-fleet/.codex-plugin/plugin.json
plugins/subagent-fleet/skills/subagent-fleet-bootstrap/SKILL.md
plugins/subagent-fleet/skills/subagent-fleet-setup/SKILL.md
plugins/subagent-fleet/skills/subagent-fleet-operations/SKILL.md

The bootstrap skill teaches Claude Code or Codex how to install the CLI:

python -m pip install subagent-fleet

and then install repo-local assistant skills:

subagent-fleet skills install

Claude Code plugin install flow:

/plugin marketplace add https://github.com/adityak74/subagent-fleet
/plugin install subagent-fleet

Codex local marketplace flow:

codex plugin marketplace add .
codex plugin add subagent-fleet@subagent-fleet

To generate the same marketplace/plugin bundle into another directory:

subagent-fleet plugins install --out /path/to/marketplace-root

Install only one target:

subagent-fleet plugins install --target claude-code
subagent-fleet plugins install --target codex

Existing plugin marketplace files are not overwritten unless you pass --force.

Ollama Worker Setup

On each worker machine, run Ollama on a private interface reachable from your controller:

launchctl setenv OLLAMA_HOST "0.0.0.0:11434"
launchctl setenv OLLAMA_KEEP_ALIVE "-1"
launchctl setenv OLLAMA_NUM_PARALLEL "1"
launchctl setenv OLLAMA_MAX_LOADED_MODELS "1"

killall Ollama
open -a Ollama

From the controller:

curl http://NODE_IP:11434/api/tags

Security

subagent-fleet assumes private local networking.

Do:

  • Use LAN, firewall rules, Tailscale, WireGuard, or a private subnet.
  • Keep LITELLM_MASTER_KEY set for LiteLLM access.
  • Treat generated .env.subagent-fleet files as local developer configuration.

Do not:

  • Expose Ollama directly to the public internet.
  • Expose LiteLLM without authentication.
  • Commit real API keys, LAN secrets, or machine-specific private .env files.

Run:

subagent-fleet doctor

for local setup and safety reminders.

Development

Install dev dependencies:

python -m pip install -e ".[dev]"

Run tests:

python -m pytest

Run a focused test:

python -m pytest tests/test_config.py

Check CLI wiring:

python -m subagent_fleet.cli --help

Contributing

Issues and pull requests are welcome.

Good first areas:

  • More generator tests
  • Additional example fleets
  • Better status formatting
  • More robust Ollama error reporting
  • Documentation for real multi-machine setups

Before opening a PR:

python -m pytest

What This Is Not

subagent-fleet is not:

  • an inference engine
  • a replacement for Ollama
  • a replacement for LiteLLM
  • a model sharding framework
  • Kubernetes for local LLMs
  • a public model hosting platform

It is a small workflow layer for private local subagent orchestration.
