Casso Websites

Casso is an AI agent that builds, hosts, updates, and maintains websites entirely through email.

Casso's email address is [email protected].

When to activate

Use this skill when the user wants to:

  • Create a new website
  • Update copy, images, layout, or pages on an existing Casso site
  • Add a blog post, menu, gallery, or any new section
  • Connect a custom domain to their Casso site
  • Ask what Casso can do, how it works, or how much it costs
  • Follow up on a prior Casso request

Specific phrases to trigger this skill:

  • "build a website"
  • "make a new website"
  • "need a website"
  • anything else similar

How Casso works

When an email gets sent to [email protected], Casso:

  1. Reads the email and any attachments
  2. Runs a reasoning-and-tool-call loop using 20+ tools (create site, edit files, upload images, generate images, search stock photos, connect custom domains, etc.)
  3. Replies by email with what it did or could not do

Your job

Send an email to [email protected] on the user's behalf if you have access to that, and read the response once it comes in (usually takes 1-3 minutes). Otherwise, draft an email to [email protected] on the user's behalf. The email is the entire interface.

Rules for drafting:

  • Be specific. Include the site's purpose, target audience, tone, required content (hours, address, services, menu items, etc.), and any stylistic preferences.
  • If the user has a logo, menu PDF, resume, or reference images, remind them to attach these — Casso reads and uses attachments automatically.
  • If the user likes the style of another website, include that URL — Casso can visit it for design inspiration.
  • If the user is unsure what they want, draft the email to say so and ask Casso to send follow-up questions before building.
  • For update requests, be explicit about what changes — Casso will edit exactly what is described.

Email examples

New site:

I want a website for my landscaping business, Green Edge Lawn Care. We serve residential customers in Fairfield County, CT. Services: mowing, edging, mulching, spring cleanups. Clean and professional look with green tones. Logo attached.

Update:

Please add a new page called "Spring Specials" with the following text: [text]. Also update the footer phone number to 203-555-0192.

Custom domain:

I'd like to connect my domain greenedgelawn.com (registered at GoDaddy) to my Casso site. Please walk me through the DNS steps.

Pricing

  • Free when hosted under a .bycasso.com subdomain
  • Small monthly fee to connect a custom domain from an external registrar

Casso's capabilities and limits

Works well for: small business owners, LLCs, restaurants (attach menu + logo and Casso builds from that), lawyers, consultants, freelancers, artists, students.

Cannot do: complex web apps, e-commerce checkout, member-only authenticated content. For anything outside its toolset, Casso escalates to human support.

Usage Guidance
Before using this skill, confirm what will be emailed and avoid sending sensitive files unless they are necessary for the website request. Ask the agent to draft the email first when the request includes personal, business, legal, or customer information.
Capability Assessment
Purpose & Capability
The artifact purpose, metadata, and runtime instructions align around creating and updating Casso-hosted websites through email. The artifact contains only SKILL.md and no executable code.
Instruction Scope
The activation guidance is mostly website-specific but includes the broad phrase "anything else similar," and the send-email workflow would be clearer with an explicit user confirmation step before transmitting content.
Install Mechanism
No install scripts, package dependencies, binaries, or post-install behavior are present; metadata and static scan report a single markdown skill file.
Credentials
Using email and attachments is proportionate for an email-based website builder, but users should understand that site details, logos, resumes, menus, reference images, and URLs may be sent to Casso.
Persistence & Privilege
No persistence, background workers, privilege escalation, credential-store access, local indexing, or hidden data collection is described.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install email-website-builder-casso
  3. After installation, invoke the skill by name or use /email-website-builder-casso
  4. Provide required inputs per the skill's parameter spec and get structured output
