Getting Started

Welcome to LoopTroop! This guide takes you from zero to your first AI-driven development cycle.

TIP

You don't need expensive API keys to get started. LoopTroop supports free-tier models from OpenRouter, NVIDIA NIM, or OpenCode. See Setting Up Your AI Council below.

1. Prerequisites

Two things every channel needs, because none of them install it for you:

• OpenCode v1 or v2, with a configured provider and an available model.
• A local git repository with an origin pointing to GitHub.

Everything else depends on how you install it. Homebrew and Scoop bring their own Node, git and gh, while npm, bun and pnpm expect you to have them. Each tab in the next section states its own requirements, so you only read the one you are using.

Why a VM?

LoopTroop runs OpenCode in dangerously-skip-permissions (or YOLO) mode so that long-running autonomous tasks can proceed without human prompts. This means the agent executes with your local user privileges. AI agents are not perfect.

WARNING

Run LoopTroop inside a disposable VM, cloud dev machine, or sandboxed environment.

Git worktrees protect your repository checkout, but they do not sandbox command execution. A bad generation could delete system folders, corrupt configs, or break your workspace. Worktrees protect code; a VM protects everything else.

2. Installation

Pick one. Each tab says what it needs beyond the command itself.

curl

curl -fsSL https://www.looptroop.ovh/install | sh

PowerShell

irm https://www.looptroop.ovh/install.ps1 | iex

npm

npm install -g looptroop

Homebrew

brew install looptroop-ai/tap/looptroop

Scoop

scoop bucket add looptroop https://github.com/looptroop-ai/scoop-bucket
scoop install looptroop

bun

bun add -g looptroop

pnpm

pnpm add -g looptroop

Yarn (Bash/zsh)

yarn global add looptroop
export PATH="$(yarn global bin):$PATH"
# Yarn Classic, Bash/zsh. Add the PATH line to your shell profile.
# Use npm in PowerShell.

Docker

docker pull looptroopai/looptroop:latest

Channel	What it needs first
curl / PowerShell	Node 24.18.0+, git, gh. The installer resolves the newest release, checks it against that release's checksum and hands it to npm. It never installs Node or asks for sudo.
npm	Node 24.18.0+, git, gh
Homebrew	Nothing else: it pulls in node@24 and gh, and takes git from the OS
Scoop	Nothing else: it depends on nodejs-lts, git and gh
bun	bun and Node 24.18.0+ (the launcher is a Node program), git, gh
pnpm	pnpm and Node 24.18.0+, git, gh. pnpm will not resolve a tag to a version published in the last 24 hours
Yarn (Bash/zsh)	Yarn Classic and Node 24.18.0+, git, gh. Yarn 2 removed global installs, so modern Yarn cannot install a CLI at all
Docker	Only Docker. The image includes Node, git and gh, but still needs an OpenCode server it can reach

Installation covers every channel in full: upgrading, uninstalling, the standalone executable that carries its own Node runtime, and verifying a download.

3. Starting the Application

looptroop open

That is both steps: open starts LoopTroop in the background if it is not already running, then points a browser at it. It serves the interface and the API from one address on port 3000.

looptroop status    # is it running?
looptroop logs -f   # what is it doing?
looptroop stop

Every command and flag is in the CLI Reference. Settings, ports and the configuration directory are in Configuration; when something misbehaves, Runtime Diagnostics covers looptroop doctor and the rest; Installation covers upgrading and uninstalling; and Operations covers running it day to day.

4. Setting Up Your AI Council

LoopTroop works best with multiple AI models. They draft, vote on, and refine plans together before any code is written. You can configure your council models inside the app via the Configuration button on the dashboard.

You need at least a Main Implementer Model (which writes and validates code) and 1 to 9 additional Council Members (which challenge and improve the plan), for a maximum council size of ten. See Configuration for all settings and trade-offs.

Configure provider credentials and providers in OpenCode. LoopTroop's model selectors show the models OpenCode reports as available; choose one in the Configuration screen.

Choosing Your Main Implementer

The Main Implementer is the model that actually writes, fixes, and validates your code, so it needs to be the strongest model you can access. Pick a frontier-class model with strong coding benchmarks:

• OpenAI: top models via API key or a Codex subscription through OpenCode
• Anthropic: latest Claude models via API key
• Google: latest Gemini model via API key
• Any other top-tier model: check the Chatbot Arena leaderboard or coding-specific benchmarks like SWE-bench to find the current best performers

Council members can come from different providers. That diversity improves plan quality because different models catch different blind spots; we recommend using models from different providers and families for the council. You can also experiment with weaker models in the council to save costs. They still provide value by catching basic mistakes and asking clarifying questions.

Free Model Options

You don't need paid API keys to get started. Here are three ways to access free models:

OpenRouter (Recommended)

OpenRouter provides a unified API with a dynamic router that selects available zero-cost models.

1. Create a free account at openrouter.ai.
2. Open OpenCode and connect to OpenRouter using your API key.
3. In LoopTroop, set your model to openrouter/free. It automatically routes to available free models capable of tool-calling. You can also pick specific models from the catalog; they rotate every few days.

NVIDIA NIM API

NVIDIA provides GPU-accelerated endpoints. Signing up gives you 1,000 base credits (up to 5,000 trial credits).

1. Create a Developer account at build.nvidia.com.
2. Generate a personal key in the API Keys section and connect it to OpenCode.

OpenCode Go

OpenCode curates models benchmarked for agentic coding, more details at OpenCode docs.

Latency & model tracking tools

Free APIs can experience rate-limiting or latency spikes. Community trackers help you route efficiently:

• free-ai-tools: master directory of 550+ free APIs, IDEs, and local RAG stacks.
• ClawRouter: open-source routing layer tracking real-time free model latency with load balancing.
• frouter: CLI tool to ping free models and test Time To First Token (TTFT) before starting your loop.

5. Attaching Your First Project

1. Open the interface with looptroop open.
2. Click Add Project and provide the absolute path to your local git repository.
3. LoopTroop verifies it is a valid git repo with a GitHub origin.
4. If the repository is already attached, LoopTroop warns you and stops the duplicate add. Project names and short names must also be unused by other attached projects.
5. Create your first Ticket with a description of the feature or fix you want.

Once submitted, LoopTroop kicks off an interview phase to clarify your intent, then generates a structured spec and implementation plan before any code is written. You review and approve at each gate.

What Happens After Your First Ticket?

Your ticket flows through a structured pipeline. Each stage has a clear purpose and a human review gate:

1. Interview: the AI council asks targeted questions to clarify ambiguities in your request.
2. PRD: your answers are synthesized into a structured spec with epics, user stories, and implementation steps.
3. Beads: the spec is decomposed into the smallest independently implementable units of work.
4. Execution: each bead is coded, tested, and retried in an isolated worktree until it passes.
5. Review: you inspect the final diff, commits, and changes before merging.

For the full lifecycle, see Ticket Flow.

Is LoopTroop Right For Your Task?

Before you start, it helps to know which tasks LoopTroop is built for and which it is not.

LoopTroop is at its best for:

• Mid-size and large feature work where planning and correctness are paramount.
• Overnight or multi-hour runs designed to run unattended while you sleep.
• Traceable planning artifacts stored as durable local specs.
• Recoverable execution using isolated worktrees and fresh-session retry logic.
• Explicit delivery outcomes with strict human approval gates.

It is not a magic autopilot, and it is the wrong tool for:

• One-shot trivial edits or quick fixes, where the planning overhead will feel slow.
• Chat-first exploratory coding: traditional IDE-based chat assistants are better suited here.
• Unbounded autonomous runs without explicit human checkpoints.
• Cost-sensitive budgets: orchestrating multi-model councils and long retry loops uses a high volume of API tokens, though subscription plans or free-tier providers in OpenCode can reduce costs (see Free Model Options above).
• A secure sandbox: it does not replace process isolation, filesystem policy, or host-level blast-radius reduction. Always run in a disposable VM or cloud container (see Why a VM? above).
