Zé Agent

Zé is a high-performance, autonomous programming agent built in pure Go. It is designed to run locally using llama.cpp (via llama-server) and provides a minimal, powerful ANSI-based TUI.

🚀 Key Features

• Zero Dependencies: Built entirely with the Go standard library. No external bloat or supply chain risks.
• Autonomous Agent Loop: A multi-step reasoning loop that allows the agent to plan, execute tools, observe results, and iterate until a task is complete.
• Context-Aware: Automatically integrates context from ~/.agents/AGENTS.md (global) and ./AGENTS.md (local) into its system prompt.
• Smart Model Management: Automatically detects and selects the best available model on your server, with a strong preference for Gemma 4.
• Rich TUI & Markdown: A terminal interface that supports Markdown rendering (tables, lists, formatting) for readable agent responses.
• Headless Mode: Automatic detection of non-interactive environments (pipes/redirects), switching to a simplified, plain-text prompt (prompt > ) without banners or colors.
• Thinking Visibility: View the agent's reasoning process using the --show-thinking flag.
• Verbose Mode: Detailed output for tool executions and raw API communication.

🛠 Installation

Local Build

go build ./cmd/ze

Multi-platform Build (via GoReleaser)

# Install GoReleaser
go install github.com/goreleaser/goreleaser/v2@latest

# Build all platforms
goreleaser build --snapshot --clean

📖 Usage

1. Start your LLM server (e.g., llama-server):

   llama-server --hf-repo google/gemma-4-12B-it-qat-q4_0-gguf --port 8084

2. Run Zé:

   ./ze --url http://localhost:8084

Advanced Interaction

• Shell Commands: Run any shell command by prefixing it with ! (e.g., !ls). The command's output is automatically added to the conversation context.
• Multiline Input: Use /multiline to enter or paste long blocks of text. Type /send on a new line to finish and submit.

⚙️ Configuration

Command Line Flags

Flag	Environment Variable	Default	Description
--url	LLAMA_URL	http://localhost:8084	Llama server URL
--model	-		Specify model name
--timeout	LLAMA_TIMEOUT	5m	Timeout duration
--verbose	-	false	Enable verbose tool output
--verbose-api-calls	-	false	Log raw API requests/responses
--max-iterations	-	50	Maximum number of agent iterations
--show-thinking	-	false	Show reasoning process in the UI
--no-color	-	false	Disable color output
--version / -v	-	-	Show version information

Slash Commands

While inside the TUI, you can use the following commands:

• /help: Show available commands.
• /multiline: Start a multi-line input session.
• /quit or /exit: Exit the session.

🛠 Agent Capabilities (Tools)

The agent can interact with your environment using the following tools:

• read_file: Read the content of a file.
• write_file: Write or overwrite a file (reports total bytes written).
• list_files: List files and directories (supports glob patterns and recursive search).
• remove_file: Delete a file.
• edit_file: Perform precise, atomic edits on files (shows change summary).
• go_tool: Inspect Go code (docs or testing).
• web_fetch: Fetch content from web URLs (HTML, JSON, Markdown, etc.).
• git_tool: Manage git operations (diff, add, commit).
• move_file: Rename or move files and directories.

🛠 Troubleshooting

• Connection Error: Ensure llama-server is running and accessible at the URL provided via --url.
• Model Not Found: Verify that the model name is correct or allow Zé to detect it automatically.
• Permission Denied: Ensure the agent has read/write permissions in the directory it is operating in.
