Pytxo

Every Pytxo run goes through three safety and efficiency layers.

What it does	Feature	Function
Smarter context	Signal Core	Send agents code skeletons so they spend tokens on work, not noise
Safe sandbox	Blast Shield	Keep writes isolated until you approve a merge
No write collisions	Race Shield	Registry + stdin buffering so swarms do not stomp each other

                      Agents

On Galaxy, human approvals add a fourth layer for risky commands and merges.

Today, agents run in isolated copies of your repo (git worktrees by default), and Race Shield tracks write claims so parallel work does not collide. See Signal Core for how context scaffolding works.

Each moat has its own concept page with configuration options.
