How Halcyon works
Agents with written rules, real tools and hard limits.
Each Halcyon agent runs inside your stack, follows rules you can read, and stops where you tell it to. A person approves anything that matters.

Anatomy
Every agent is three things: rules, tools and limits.
You write them down with us in the first week. The agent follows them on every run, and you can read or change them at any time.
Rules
Plain sentences that say what the agent does and where it stops. No prompt engineering on your side.
Tag each ticket with one topic

Approvals
A person signs off on anything that matters.
You decide which actions need a human. The agent prepares the work, attaches its reasons and waits. Approvals arrive in Slack or Teams, where your team already is.
Approve, edit or reject in one click
Edits are saved next to the original draft, so you can see what changed and why.
Nothing waits forever
Open approvals are escalated after the time you set. They are never sent on their own.
Limits sit outside the model
A clever prompt cannot talk its way past a hard limit. The platform enforces it.

Every run is written down. Inputs, outputs and who said yes.
Search it, filter it and export it for your auditors. Nothing an agent does happens off the record.
