6 karma · joined September 3, 2026

Solo founder building infrastructure for AI agents. Most of my work is around one question: how do you let an agent run on its own without it doing something dumb with real money, real customers, or a production box.

What I spend my time on:

Approval and policy layers so agents can be trusted with risky actions. That's DashClaw: https://www.dashclaw.io

Running Claude Code, OpenClaw, and Codex as daily drivers and open sourcing the setup. My hooks, skills and rules: https://github.com/ucsandman/claude-harness

Turning any API, MCP server or desktop app into a CLI an agent can call: https://declick.dev

An LLM-driven discovery loop that runs overnight. It beat 10 Packomania circle packing records for about $28: https://github.com/ucsandman/discovery-loop

Driving phones and desktops from LLM agents, writing poker solvers (I played pro before any of this), and shipping small products to see what sticks.

Everything else lives at https://www.practicalsystems.io and https://github.com/ucsandman

Based in Ohio. If you're building agent infra, email is wes@practicalsystems.io.

definitely sending this to claude to take lessons from it and audit my harness, thanks for sharing

neat idea, I'm in there as @ucsandman!

worked for me, got a 98.2/100 on dashclaw.io

neat idea

practicalsystem··on OpenAI Agents API
oof, sorry to hear that
practicalsystem··on Muse – Meta’s personal AI agent
Pretty happy with the experience of using it so far. Asked it to do something to blow me away and it made a podcast about the features it made while onboarding itself to my opensource project called DashClaw.

Then I had it make a marketing video as a test, pretty neat. Obviously all of this was doable but quite impressed with the model underneath since it's all free, for now.

practicalsystem··on I Hardened a Personal AI Agent That Reads My Email, Files, and Desktop
tldr;

private data + untrusted content + outbound capability = hard stop

a markdown file is a wishlist, real security lies within hooks and plugins

practicalsystem··on Ask HN: Fable hacked my piano, can I release the results?
it's wild how far behind society is to current LLM capabilities
practicalsystem··on Show HN: Personal Context MCP
is there a way to load my current agents memory because I don't want to start over fresh
practicalsystem··on GPT-6 Astra: the harness is the product
I wish they would just call us problem solvers and be done with it, that's all it's ever been and ever will be

honestly this was in June which feels like forever ago and I'm not entirely sure what my plan was haha. I knew I was going to be doing marketing for my projects and thought an editor with LLM capabilities would make it easier, but then I just made a repo and a skill where agents can make marketing material directly

cool going to check it out, I've got an opensource project that might compliment it that I'm excited to try

practicalsystem··on GPT-6 Astra: the harness is the product
harness engineering will be a job in the future imo
practicalsystem··on Show HN: Personal Context MCP
great idea, excited to test it out between my openclaw agents, claude, and codex
practicalsystem··on Show HN: Fast Cut Video tool for cutting video for Agents
excited to test it, great idea

I had a similar idea for an opensource video editor where you edit along side the LLM but I gave up on it haha

practicalsystem··on Show HN: Declick – Turn an OpenAPI Spec, MCP Server or SQLite DB into a CLI
thanks! would love some feedback if you have any

going to have claude go through all these posts and update it's harness, hilarious idea for a site but sneaky useful I think

great timing with codex, claude, cursor, and grok being down

long live opensource

great idea thanks for sharing

website is clean, definitely going to check this out, is there a beta signup list for windows?
