hey-cli-python 1.0.4

A secure, zero-bloat CLI companion that turns natural language and error logs into executable commands.

hey-cli

Your terminal buddy that turns plain English into shell scripts — and runs them for you.

hey is a terminal-native AI assistant that translates plain English into executable shell commands using a locally-hosted LLM via Ollama. Your data never leaves your machine.

$ hey find all python files modified in the last 24 hours
● Thinking...

▶ find . -name "*.py" -mtime -1 -type f

Run this command? [Y/n]:

Features

• 100% Local & Private — All reasoning happens on your machine via Ollama. No API keys, no cloud, no telemetry.
• Cross-Platform Intelligence — Detects your OS (macOS/Linux/Windows) and generates the correct flags. Won't suggest xargs -d on BSD or apt on Arch.
• Agentic Context Gathering — Ask "is Docker running?" and hey silently runs diagnostics, reads the output, and answers in plain English.
• Security Governance — Dangerous commands (rm -rf, mkfs, DROP TABLE) are intercepted and require explicit confirmation before execution.
• Pipe-Friendly — Pipe error logs directly: npm run build 2>&1 | hey what is causing this error?
• Conversational Memory — Remembers your recent interactions for follow-up questions.

Installation

hey requires Ollama running locally. Install it first, then choose your platform:

macOS (Homebrew)

brew tap sinsniwal/hey-cli
brew install hey-cli

macOS & Linux (curl)

curl -sL https://raw.githubusercontent.com/sinsniwal/hey-cli/main/install.sh | bash

Windows (Scoop)

scoop install https://raw.githubusercontent.com/sinsniwal/hey-cli/main/scoop/hey-cli.json

Windows (PowerShell Installer)

Invoke-WebRequest -Uri "https://raw.githubusercontent.com/sinsniwal/hey-cli/main/install.ps1" -OutFile "$env:TEMP\hey_install.ps1"; & "$env:TEMP\hey_install.ps1"

Windows (Standalone Binary)

Download hey.exe from the latest release. No Python required.

pip / pipx

pipx install hey-cli-python

Note: After installation, pull the default model: ollama pull gpt-oss:20b-cloud

Usage

hey <your objective in plain English>

Examples

Command	What happens
hey list all running docker containers	Generates and runs docker ps
hey is port 8080 in use?	Silently runs lsof -i :8080, reads output, answers in English
hey forcefully delete all .pyc files	Generates find . -name "*.pyc" -delete, pauses for confirmation
hey compress this folder into a tar.gz	Generates the correct tar command for your OS
npm run build 2>&1 | hey what broke?	Reads piped stderr and explains the error
hey --clear	Wipes conversational memory

Execution Levels

Level	Flag	Behavior
0	--level 0	Dry-run — shows the command but never executes
1	(default)	Supervised — safe commands auto-run, risky ones ask for confirmation
2	--level 2	Unrestricted — executes everything without confirmation
3	--level 3	Troubleshooter — iteratively debugs until the objective is resolved

---

Security

Safety is enforced at runtime via a local governance engine (~/.hey-rules.json):

• Blocked — rm -rf /, mkfs, :(){ :|:& };: are permanently rejected.
• Explicit Confirm — High-risk operations (rm, truncate, DROP) require typing a keyword to authorize.
• Y/N Confirm — Moderate-risk operations require a quick y.
• Auto-Run — Safe diagnostics (ls, cat, grep, git status) execute immediately.

Initialize or customize your rules:

hey --init

OS Skills

hey ships with built-in knowledge for macOS, Ubuntu/Debian, Arch Linux, Fedora/RHEL, Windows PowerShell, FreeBSD, and ChromeOS.

Want to improve it for your OS? Add a Markdown file to hey_cli/skills/ with plain-English rules (e.g., "On Alpine, use apk add instead of apt install"). The engine loads them dynamically at runtime.

Pull requests for new OS skills are welcome!

• Zero external API calls — communicates with Ollama via localhost:11434 using Python's built-in urllib.
• Zero compiled dependencies — the only runtime dependency is rich (for terminal formatting).
• Pure Python 3.9–3.14 — no C extensions, no Rust, no build tools required.
