How to Use OpenClaw as Your Coding Assistant

Most coding assistants live inside a subscription editor and forget everything the moment you close the tab.

OpenClaw, on the other hand, runs on your own machine, takes instructions through Telegram or Slack, and keeps working while you sleep.

You send a plain-language message from your phone.

OpenClaw reads the files in your project folder, writes code into the right place, runs your tests, and reports back all without opening a new IDE.

That’s the core promise. And it’s real.

I will take you through how to use OpenClaw as your coding assistant once it’s set up.

If you’re still at the installation stage, start with our OpenClaw VPS setup guide first, then come back here.

Prerequisites

Before you start using OpenClaw as your coding assistant, confirm you have the following in place.

Node.js version:

• Node.js 24 (recommended) or 22.19 and above

A model provider pick one:

• An Anthropic API key (for Claude)
• An OpenAI API key (for GPT-4)
• A Google Gemini API key
• Ollama for free local models no API key required

A messaging channel:

• Telegram is the fastest to connect for solo developers
• Slack works better for team setups

A machine that stays on:

• Your laptop works for testing
• A VPS is better for always-on use (more on that at the end)

Install and configure

Run the install command for your system:

macOS / Linux:

curl -fsSL https://openclaw.ai/install.sh | sh

Windows PowerShell:

iwr https://openclaw.ai/install.ps1 | iex

Or via npm:

npm install -g openclaw

Verify the install:

openclaw --version

Then run the setup wizard:

openclaw onboard --install-daemon

The wizard walks you through your workspace folder, model provider, messaging channel, and daemon configuration. Your config is stored at ~/.openclaw/openclaw.json. Run openclaw doctor at any point to check your setup.

Model provider comparison

Connect Telegram

1. Open Telegram and search for @BotFather
2. Run /newbot and follow the prompts
3. Copy the API token BotFather gives you
4. Add it to your openclaw.json under the Telegram channel settings
5. Restart the daemon with openclaw gateway restart

Send your bot a message. If it replies, you’re connected.

How to Generate Code with OpenClaw

You send a plain-language prompt through your messaging channel.

OpenClaw reads your project files, reasons over the request, and writes the output directly into the correct folder.

The more file context you include in your prompt, the more accurate the result. Paste a file path or name the specific module you’re working on.

Example prompts you can use right now:

• “Generate CRUD endpoints for the User model in /src/routes/users.ts”
• “Read /src/types/api-response.json and write TypeScript interfaces for it”
• “Create a Dockerfile for the Node.js app in the root directory. Use the 22-alpine base image.”
• “Scaffold a new Python project in /projects/scraper with src, tests, and docs folders. Add a basic pyproject.toml.”

Reference specific module names in your prompt. A prompt like “generate endpoints for the User model in /src/routes/users.ts” produces tighter output than “add some CRUD routes.”

How to Debug Code with OpenClaw

OpenClaw can run your tests, read the output, and reason over a stack trace in a single session.

You don’t need to copy-paste errors into a separate chat window. The whole loop happens in your messaging channel.

Example prompts:

• “Run npm test in /src and summarize the failures”
• “Here’s the stack trace from the last deploy; suggest a fix: [paste raw error output].”

Paste the full, raw error output into the chat. Don’t paraphrase it. OpenClaw reads raw logs better than summarized descriptions. Stack traces contain line numbers and module paths that are important.

How to Handle Code Maintenance Tasks

Repetitive, project-wide tasks are where OpenClaw saves the most time. It can apply a change across every file in a folder in one instruction.

This is the kind of work that takes hours to do manually, reformatting, removing dead code, and standardizing imports.

OpenClaw handles the scope; you review the result.

Example prompts:

• “Format all Python files in /src with Black”
• “Scan all files in /src/utils and remove unused imports”

Always specify the scope in your prompt. “All files in /src” avoids unintended changes in nested or shared directories. Be as specific as you would be with a junior developer.

How to Run Multi-Step Pipelines

You can chain multiple actions into a single prompt. OpenClaw executes them in sequence. This is useful for common development loops: pull, install, test, restart.

Example pipeline prompt:

“Pull the latest from the main branch on GitHub, install dependencies with npm install, run the test suite, and restart the server only if all tests pass.”

OpenClaw follows numbered steps more reliably than a single run-on sentence. If your pipeline is complex, break it into ordered instructions:

1. Pull latest from GitHub
2. Run npm install
3. Run npm test
4. If tests pass, restart the server with pm2 restart app

Use numbered steps inside your prompt. “Step 1, Step 2…” gives OpenClaw a clear execution order to follow.

How to Send a File for Review

Attach a file in your messaging channel or paste a file path directly into the chat. OpenClaw reads it and gives you feedback.

This works for any file type in your workspace folder: TypeScript, Python, YAML, SQL, Markdown, and configuration files.

Example prompts:

• “Review the logic in /src/auth/middleware.ts. Flag any security issues.”
• “Look at /src/db/queries.sql and suggest refactors for readability.”
• “Check /src/api/payments.ts for potential injection vulnerabilities.”

You don’t need to copy the file contents into the chat. Just paste the path. OpenClaw reads the file directly from your workspace.

How to Extend OpenClaw with Skills (Optional)

Skills are instruction packs that add specialized workflows to OpenClaw. They’re stored as SKILL.md files and loaded into your agent’s context automatically when relevant.

Useful skill categories for developers include:

• Advanced code review workflows
• Project memory across sessions
• CI/CD automation
• GitHub PR review and submission

How to find and install skills:

# Search for code-related skills
openclaw skills search code

# Install a specific skill
openclaw skills install @namespace/skill-name

ClawHub is OpenClaw’s official skill registry. As of early 2026, it hosts over 13,700 skills.

Security warning read this before installing anything

In early February 2026, Bitdefender Labs reported that approximately 17% of OpenClaw skills analyzed in the first few weeks of the platform’s release carried malicious payloads.

A coordinated campaign called ClawHavoc was discovered, where 341 malicious skills were hidden inside the ClawHub marketplace, many disguised as legitimate productivity tools.

The attack worked by including a fake “Prerequisites” section that directed users to install malware before the skill would function.

ClawHub has since integrated VirusTotal and ClawScan scanning. But this does not make third-party skills safe by default.

Follow these rules before installing any skill:

• Only install skills from verified publishers with substantial review history
• Check the publisher’s GitHub account age and contribution history
• Read the full SKILL.md file before installing, look for unusual prerequisites
• Treat every third-party skill as untrusted code

The official OpenClaw documentation says the same thing.

Treat skill installation like running a third-party script with privileged system permissions. Because that’s what it is.

How to Keep OpenClaw Running 24/7 (Optional)

Your laptop sleeps. A background service doesn’t.

If you want OpenClaw available at all hours, responding to messages, running scheduled tasks, finishing a pipeline you started, you need it running on a persistent process or machine.

Setup by operating system:

macOS, launchd plist:

Create a .plist file in ~/Library/LaunchAgents/ that starts the OpenClaw daemon on login and restarts it if it crashes.

Linux, systemd service:

Create a service file at /etc/systemd/system/openclaw.service. Set Restart=always so it recovers from failures automatically.

[Unit]
Description=OpenClaw Daemon
After=network.target

[Service]
ExecStart=/usr/local/bin/openclaw gateway start
Restart=always
User=your-username

[Install]
WantedBy=multi-user.target

Enable and start it:

sudo systemctl enable openclaw
sudo systemctl start openclaw

Windows, NSSM:

Use NSSM (Non-Sucking Service Manager) to wrap the OpenClaw process as a Windows service. It handles restarts and runs in the background without a terminal window.

Best practice: run on a VPS

Your laptop changes networks, loses power, and restarts. A VPS doesn’t.

Running OpenClaw on a cloud server gives you a stable IP, continuous uptime, and no dependency on your local machine.

We at Truehost offer OpenClaw-ready VPS plans in South Africa with pre-configured Node.js environments. You can get a server running in minutes.

Troubleshooting Table

Run openclaw doctor first whenever something isn’t working.

It catches the most common issues, model config errors, missing tokens, and misconfigured channels in one pass.
