What Are OpenClaw Skills?
If you’ve already set up OpenClaw on your contractor business, you’ve got a capable AI agent running on your own hardware. But out of the box, OpenClaw is a brain without hands. It can think, reason, and chat — but it can’t check your email, pull up a camera feed, or send a text to your lead carpenter.
Skills change that.
A skill is a self-contained package that teaches your OpenClaw agent how to use a specific tool or service. Install the weather skill, and your agent can check tomorrow’s forecast before you pour concrete. Install himalaya (email), and it can scan your inbox for urgent RFIs. Install slack, and it can post daily job updates to your team channel.
Think of skills like apps on your phone. Your phone’s useful out of the box, but it gets way more useful once you install the apps that fit your workflow.
The difference: OpenClaw skills aren’t just passive apps. They give your AI agent the ability to act — read data, make decisions, and execute tasks on your behalf. An electrician’s agent doesn’t just display a calendar. It reads the calendar, checks the weather, and sends a reschedule text to the homeowner if a storm’s rolling in.
Where Skills Come From: ClawHub
ClawHub is the central marketplace for OpenClaw skills. It’s community-driven, open-source, and free. As of early 2026, there are 50+ skills available covering everything from project management to smart home control.
You can browse skills at clawhub.com or search directly from the command line:
clawhub search weather
clawhub search email
Installing a skill is one command:
clawhub install weather
clawhub install himalaya
That’s it. The skill lands in your OpenClaw skills directory, and your agent picks it up on the next session. No restarts, no config files to edit, no Docker containers to spin up.
Updating skills is just as simple:
clawhub update weather
clawhub update --all
If you want to see what you’ve got installed, clawhub list shows everything. The whole system is designed to be low-friction — install what you need, skip what you don’t.
The Top Skills for Contractors
Not every skill on ClawHub matters for contracting work. You don’t need Spotify integration on a jobsite (well, maybe you do, but that’s a different article). Here are the skills that actually move the needle for contractors.
1. Weather — Stop Guessing, Start Planning
Skill name: weather
Every contractor checks the weather. Multiple times a day. For every job. The weather skill uses wttr.in and Open-Meteo to pull current conditions and multi-day forecasts for any location — no API key required.
Why this matters more than just checking your phone: your OpenClaw agent can check weather proactively. Set up a scheduled task and your agent checks the 5-day forecast every evening. If rain’s coming, it flags the affected jobs. A concrete contractor doesn’t want to find out about Thursday’s downpour on Thursday morning.
Pair this with the Slack or email skill, and your agent can send weather alerts to your crew leads automatically. “Hey, rain forecast for the Thompson job Thursday. Plan interior work.”
2. Himalaya (Email) — Your Inbox, Handled
Skill name: himalaya
Email runs a contractor’s business whether you like it or not. GC sends scope changes over email. Homeowners send approval photos. Suppliers confirm delivery dates. The himalaya skill gives your agent full email access via IMAP/SMTP — list, read, search, reply, forward, and organize.
Real use case: you’re a plumbing contractor with 15 active jobs. Every morning, your agent scans overnight emails, flags anything urgent (inspection notices, material delays, customer complaints), and gives you a prioritized summary before your first cup of coffee. It can even draft replies for your review.
For a GC managing multiple subs, this is a game-changer. Your agent can monitor a dedicated project email, extract schedule updates from sub emails, and compile them into a daily status report. No more digging through 80 emails to figure out who’s showing up tomorrow.
Setup requires your email credentials (IMAP server, username, password). Everything stays on your machine — your email never touches a third-party cloud service. That’s the self-hosted advantage of OpenClaw.
3. Slack — Team Communication on Autopilot
Skill name: slack
If your crew uses Slack (and more trade shops are adopting it every year), the slack skill turns your agent into a team communication hub. It can post messages, react to updates, pin important items, and monitor channels.
Practical example: an HVAC company with three install crews. The OpenClaw agent posts each crew’s daily schedule to their channel every morning at 6 AM. When a job wraps early, the office agent reprioritizes and posts the next assignment. End of day, it compiles hours and job notes from the channel into a summary for the owner.
The skill supports channel-specific messaging, so your agent can post material orders to #purchasing, schedule updates to #dispatch, and safety reminders to #field-crew — all without manual intervention.
4. Trello — Visual Job Tracking
Skill name: trello
Plenty of contractors use Trello boards to track job progress. The trello skill gives your agent full access to boards, lists, and cards via the Trello REST API.
A painting contractor might have columns for “Estimate Sent,” “Scheduled,” “In Progress,” “Punch List,” and “Complete.” The agent can move cards between columns based on email updates, add due dates, attach photos, and flag cards that have been sitting in one column too long.
For a GC, Trello boards can track each sub’s progress. Your agent reads daily check-in emails from subs and updates the board automatically. The PM opens Trello and sees current status without making a single phone call.
5. Notion — The Contractor’s Knowledge Base
Skill name: notion
Notion works well as a contractor’s central operations hub — SOPs, vendor contacts, material specs, warranty info. The notion skill connects your agent to the Notion API for creating, reading, and updating pages and databases.
An electrical contractor could maintain a Notion database of every panel they’ve installed — location, capacity, manufacturer, install date. When a callback comes in, the agent searches the database and pulls up the original job details instantly.
It’s also useful for onboarding. Your agent can pull the latest version of your safety procedures or tool list from Notion and send it to a new hire’s email before their first day.
6. CamSnap — Jobsite Camera Monitoring
Skill name: camsnap
This one’s underrated. The camsnap skill captures frames and clips from RTSP/ONVIF security cameras. If you’ve got cameras on your jobsite (and you should), your agent can pull snapshots on a schedule.
Why contractors care: theft prevention and progress documentation. Set your agent to capture a frame from each jobsite camera every hour during off-hours. If something looks wrong, it flags it. During business hours, periodic captures create a visual timeline of job progress — useful for billing disputes, insurance claims, and client updates.
A GC running three active jobsites can get a morning photo summary of all sites without driving to any of them. That’s 45 minutes of windshield time saved every day.
7. Voice Call — AI-Powered Phone Handling
Skill name: voice-call
The voice-call skill integrates with Twilio, Telnyx, or Plivo to handle phone calls through your agent. This is the backbone of AI answering services for contractors — but running on your own infrastructure.
A one-truck plumber misses calls all day because they’re under a house. With the voice-call skill, their OpenClaw agent answers, captures the caller’s info and issue description, and schedules a callback. No missed leads. No third-party answering service at $200/month.
For larger operations, the agent can handle initial screening: “Is this an emergency? What’s your address? What type of service do you need?” Then route the call or message to the right dispatcher.
8. Apple Reminders / Things — Personal Task Management
Skill names: apple-reminders, things-mac
These skills sync your agent with Apple Reminders (via remindctl) or Things 3. Good for owner-operators who manage their task list on their phone.
Your agent finishes processing the day’s emails and creates reminders: “Call Thompson about change order,” “Order 200ft 12/2 Romex for Friday,” “Follow up on permit #2847.” These show up on your iPhone instantly. No manual entry.
The apple-reminders skill is macOS-only, which fits the OpenClaw sweet spot since most installations run on Mac hardware.
9. OpenHue — Smart Jobsite/Office Control
Skill name: openhue
Philips Hue might sound like a homeowner thing, but contractors running an office or shop benefit from smart lighting control. The openhue skill controls lights and scenes via the OpenHue CLI.
More interesting: contractors who do smart home installs can use this skill to demo and test Hue setups for clients. Your agent can trigger lighting scenes, adjust brightness, and control individual fixtures — useful for final walkthroughs and client handoffs.
10. GoPlaces — Location Intelligence
Skill name: goplaces
The goplaces skill queries the Google Places API for business search, place details, and reviews. For a contractor, this means market intelligence.
Want to know every electrical contractor within 20 miles of a new service area you’re expanding into? Your agent can pull that data, including ratings and review counts. Planning a commercial bid? Pull details on the building, nearby suppliers, and parking logistics.
It’s also useful for finding suppliers on the fly. “Find the nearest electrical supply house to 425 Oak Street” — your agent returns the answer with hours, phone number, and distance.
Building Custom Skills
The skills on ClawHub cover a lot of ground, but every contracting business has unique needs. Maybe you use a niche estimating tool with an API. Maybe you’ve got a custom inventory spreadsheet. OpenClaw lets you build skills for exactly these situations.
A custom skill is just a directory with a SKILL.md file that tells your agent how to use a tool. At minimum, you need:
my-custom-skill/
├── SKILL.md # Instructions for the agent
└── references/ # Optional: API docs, examples
└── api-guide.md
The SKILL.md file is written in plain Markdown. You describe when to use the skill, what commands or APIs to call, and what the expected outputs look like. Your agent reads this file and follows the instructions.
Here’s a simplified example for a contractor who wants their agent to check a custom job management API:
# Job Status Checker
Use when the user asks about job status, upcoming jobs,
or crew assignments.
## API
- Base URL: https://api.myjobsystem.com/v1
- Auth: Bearer token in $JOB_API_KEY
- GET /jobs?status=active — list active jobs
- GET /jobs/{id} — job details with crew assignments
- GET /jobs/{id}/notes — job notes and updates
That’s a functional skill. Your agent now knows how to query your job management system. You can get as detailed as you want — add error handling instructions, output formatting preferences, or multi-step workflows.
The skill-creator skill on ClawHub even helps you build new skills interactively. And if you build something useful, you can publish it back to ClawHub for other contractors to use:
clawhub publish my-custom-skill/
For a deeper look at building multi-agent workflows that chain multiple skills together, check our dedicated guide. That’s where skills get really powerful — an agent that checks weather, updates the schedule, notifies affected crews, and reorders materials, all triggered by a single weather alert.
What About Costs?
Most skills on ClawHub are free and open-source. The skills themselves don’t add to your AI costs — they’re just instruction sets.
Your costs come from the underlying services some skills connect to:
- Weather: Free (uses open APIs)
- Email (Himalaya): Free (uses your existing email account)
- Slack: Free tier works, paid Slack plans are per-user
- Trello: Free tier covers most contractor needs
- Notion: Free tier available, $10/month for teams
- Voice Call: Twilio/Telnyx charges per minute (~$0.02/min)
- CamSnap: Free (uses your existing cameras)
- GoPlaces: Google Places API charges per query (pennies per call)
The big cost with OpenClaw is always the AI model usage — the tokens your agent consumes while thinking and acting. Skills don’t change that equation much. A well-configured agent with good skills might actually reduce token usage by having clear, efficient instructions for common tasks.
For a solo contractor, total monthly costs typically land between $20-50 for AI model usage plus whatever services you connect. Compare that to hiring a part-time office person or subscribing to multiple SaaS tools.
Picking the Right Skills for Your Trade
Not every contractor needs every skill. Here’s a quick guide by trade:
Solo residential trades (electricians, plumbers, HVAC):
Start with weather, himalaya (email), and apple-reminders. These three handle the basics — weather-aware scheduling, inbox management, and task tracking. Add voice-call when you’re ready to stop missing calls.
Multi-crew operations:
Everything above plus slack and trello (or notion). Communication and job tracking across crews is where AI agents shine. Your agent becomes the central dispatcher that never forgets, never sleeps, and never loses a message.
GCs managing subs:
himalaya, slack, trello, and camsnap. Email and communication skills let your agent monitor sub progress. Camera skills give you eyes on every site. The agent compiles everything into daily reports so you’re not chasing updates.
Home service companies (handyman, cleaning, lawn care):
weather, himalaya, voice-call, and goplaces. High call volume and weather-dependent scheduling are your pain points. The agent handles inbound calls, checks weather, and manages your route.
Getting Started
If you haven’t set up OpenClaw yet, start with our setup guide for contractors. Already running? Here’s the 10-minute path to your first useful skill:
-
Install the ClawHub CLI if you haven’t:
npm install -g clawhub -
Install your first skill:
clawhub install weather -
Test it. Ask your agent: “What’s the weather forecast for [your city] this week?”
-
Add email next:
clawhub install himalaya -
Configure your email credentials following the skill’s setup instructions.
-
Set up a morning routine using task automation — weather check + email summary + calendar review.
That morning routine alone — automated weather, email triage, and schedule review — saves most contractors 20-30 minutes a day. That’s over two hours a week you get back for billable work.
The Bigger Picture
Skills are what make OpenClaw practical for daily contractor operations instead of just a novelty. A bare agent is interesting. An agent with weather, email, communication, and camera skills wired into your mobile field setup is a genuine competitive advantage.
The ecosystem’s growing fast. New skills appear on ClawHub every week, and the barrier to creating your own is low. If you can describe a workflow in plain English, you can build a skill.
The contractors who’ll benefit most aren’t the ones who install every skill they find. They’re the ones who pick three or four that match their biggest pain points, configure them well, and let the agent run. Start small. Add skills as you find real needs. That’s how you build a system that actually works instead of a complicated setup that collects dust.
