nanocode-cli 0.3.26

A lightweight terminal-based AI coding assistant

nanocode

A lightweight terminal-based AI coding assistant.

nanocode is used to help building itself, including features such as @file path completion.

Pre-1.0 note: nanocode is still evolving quickly. Functionality, commands, configuration, and behavior may change incompatibly before a 1.0 release.

Features

• Constrained Output: Force model replies into auditable action frames.
• Verified Edits: Reject stale range edits before they touch files.
• Autonomous Loop: Chain reading, editing, running, and verification.
• Live Telemetry: Stream tool intent, token use, and status.

Install

uv tool install nanocode-cli

Upgrade an existing install:

uv tool upgrade nanocode-cli

For local development:

uv sync --extra dev
uv run nanocode

Usage

Start nanocode:

nanocode

Show available commands:

/help

Ask a source-aware question about nanocode itself:

/help how does compact work?

CLI arguments:

• --yolo: Skip tool execution confirmations.
• --plan: Plan changes without editing files or running commands.
• --debug: Write request prompts to the current session directory under ~/.nanocode/sessions/.
• --config <path>: Path to config file (default: ~/.nanocode/config.toml).
• --init-config: Create a default config file.
• -v, --version: Show program version.

Safety

nanocode does NOT provide sandbox protection. It can run shell commands and edit files in the environment where you start it.

If you do not fully trust the model, tools, prompts, or workspace, run nanocode inside your own sandbox, container, VM, or other isolated environment.

USE AT YOUR OWN RISK.

Tools

• File: Read, LineCount, ListDir, Search.
• Edit: Edit, ReplaceRange.
• Shell: Bash, Git.
• Memory: Recall reads stored tool results by key.

Commands

• Info: /help [question], /status, /rules, /knowledge, /compact.
• Config: /config, /set <key> <value>, /model [model_name], /reason, /provider [name], /plan [on|off|question], /yolo.
• Maintenance: /clean.
• Exit: /exit, /quit.

/model groups configured available_models first, then any extra models automatically discovered from the provider. In selectors, use j/k or arrow keys to move, /keyword to filter choices, Enter to select, and Esc to step back or cancel. /model <model_name> sets a model directly. Changing model also opens a reasoning effort selector: choose off to disable reasoning, or choose an effort to enable reasoning and set it. Use /reason to change reasoning without changing model.

Configuration

Run nanocode --init-config to create ~/.nanocode/config.toml.

• Provider config: [provider] active = "<name>" plus [provider.<name>] url, key, model, available_models, and model options. reasoning_payload controls whether effort is sent as reasoning, reasoning_effort, or not sent.
• Path config: [paths] data_dir = "~/.nanocode".
• Runtime config: [runtime].
• Session data: debug prompts and tool-result logs are stored under ~/.nanocode/sessions/<session_id>/.
• Tool-result logs from inactive sessions are auto-cleaned after runtime.auto_clean_recent (default 3d; use off to disable). /clean removes inactive session logs immediately.
• Project data: user rules are stored under ~/.nanocode/projects/<project_key>/.

Status

• Status bar: active model, reasoning, active yolo/plan modes, conversation context, current-turn tool calls, tokens, elapsed time, and active model-call time.
• /status: active provider, model state, session id, runtime state, conversation/tool counters, per-model calls/tokens, task, goal, and verification.
