⟡ Goa — Terminal-native AI Coding Agent

🌐 Website: https://pijalu.github.io/goa/ (source in web/, deployed via GitHub Pages)

Goa is a terminal-native AI coding agent with full LLM transparency, multi-agent collaboration, and an ANSI TUI engine (inspired by pi / OpenCode / kimi-code). It uses the merged Agent SDK in internal/agentic/ to orchestrate conversations with any OpenAI-compatible LLM provider (OpenAI, llama.cpp, LM Studio, Ollama) and exposes a powerful tool system for interacting with your codebase.

Status: Active development. See bugs.md for current issues.

Quick Start

# Build from source
make build

# First run launches the interactive setup wizard
./goa

On first run, Goa walks you through:

1. Configuring an LLM provider (endpoint, model, API key)
2. Selecting an agent profile (coder, planner, reviewer)
3. Choosing an execution mode (yolo, confirm, review)

Features

Feature	Description
🧠 Multi-provider	Connect to any OpenAI-compatible LLM endpoint
🛠 Tool System	Read, write, edit, search, bash, SSH, background exec, git utilities
📝 Config Cascade	Embedded defaults → home → project → local → env → CLI overrides
👤 Agent Profiles	Built-in profiles: coder, planner, reviewer — custom via extends
🧩 Skills	Reusable prompt templates — inline (system prompt injection) or sub-agent
🔁 Multi-Agent	Pair (planner → coder) and reviewer (coder → reviewer) collaboration
📋 Workflows	Multi-stage, multi-agent workflows with team collaboration and AgentBus
🧪 Loop Detection	5 heuristics (identical calls, token budget, timeout, activity, error rate)
💾 Session Persistence	Full JSONL session history with /save and /restore
📦 Diagnostic Export	Self-contained ZIP bundle via /export with events, logs, config, and issue description
🖥 Rich TUI	Chat, thinking stream, tool ledger, log, token budget, side panel, modals
🔌 JS Plugins	Extend Goa with JavaScript plugins via Goja
🔄 Execution Modes	yolo (auto-approve), confirm (pause before each tool), review (queue edits)
🔒 Git Worktree Isolation	Sandboxed agent filesystem via git worktree
🎨 Configurable Spinner	Choose from 50+ spinner styles via /config or tui.spinner
🔍 Priority Search	Search results ordered by file type (source first) with match counts
⌨️ History Persistence	Input history saved across sessions
🗑️ Model/Provider Mgmt	Delete models/providers via /config:remove or backspace in pickers
⚡ Direct Tool Execution	Run tools directly via /tools:<name>:<key>=<value>,...
