Tidy up an agent setup
from 150 €
A one-page map of what each agent does. Agents that overlap are merged, the rest become skills that load only when needed.
AI agents & automation
AI agents that follow your rules
We build and fix multi-agent setups on Claude Code: agents, hooks, skills, memory between sessions, and MCP tools that connect them to your systems. We run a setup like this every day for our own studio, so we know where they break: context that grows too long, rules that look strict but let things through, and agents that quietly stop working.

Is this for you?
- Your agent setup grew fast, and nobody is sure any more what each agent does.
- You wrote rules for your agents, but things still get through.
- You want agents to work with your email, sheets and files, but never touch confidential folders.
What we can do for you
Rules with tests
from 150 €
For every hook rule, one action that must be blocked and one that must pass. You see the test run, not just the rule.
Confidential files stay off-limits
from 150 €
Deny rules plus a hook that blocks any read of protected folders. Tested the same way: blocked and allowed cases.
Connect agents to your tools
written quote
MCP tools for your email, Google Sheets, Telegram and files. The price follows the one-page map.
Check AI output before you trust it
from 150 €
A jury of judge models from different labs instead of one model checking itself. Split cases go to an arbiter.
Python automation around it
from 150 €
PDF invoices to one checked table, an API to Google Sheets with Telegram alerts, CSV cleaning with a log of every change.
How a project starts: you describe the setup. We send a one-page map and a plan with a fixed price for the first step. Nothing goes live until you have seen it work.
