OpenClaw after 50 days: all prompts for 20 real workflows (companion to YouTube video)

OpenClaw after 50 days: all prompts

Companion prompts for the video: OpenClaw after 50 days: 20 real workflows (honest review)

These are the actual prompts I use for each use case shown in the video. Copy-paste them into your agent and adjust for your setup. Most will work as-is or the agent will ask you clarifying questions.

Each prompt describes the intent clearly enough that the agent can figure out the implementation details. You don't need to hand-hold it through every step.

My setup: OpenClaw running on a VPS, Discord as primary interface (separate channels per workflow), Obsidian for notes (markdown-first), Coolify for self-hosted services.

Ping an email address to see if it exists. This script resolves MX records to find the SMTP server responsible for delivering mail to the address, connects to it, and starts to send a message to the address. It disconnects before the message is sent.
#!/usr/bin/env ruby

# = Email Ping
#
# Check to see if an email address exists by looking up MX records and connecting
# to the address's home SMTP server. It then starts to send a message to the address
# but quits before the message is actually sent.
require 'resolv'
