Outcomes over chat
The result matters more than transcript mechanics.
Principles
Built for agents that do real work.
Protect the work. Show the result. Keep control with the operator.
Durable choices
Six product principles.
Sessions preserve work
Threads stay named, resumable, and branchable.
Everything inspectable
Tools, artifacts, files, and changes remain visible.
Local-first control
The server starts on localhost; wider access is your choice.
Focused, not an IDE
Review and intervention stay close to agent work.
Extensions are core
Specific workflows can live as source you own.
Direction boundary
Broaden without flattening.
pi is the current default and full-capability reference harness. Typed events, capabilities, and interaction plumbing are enabling foundations. They are not multi-harness product support.
Alternate harnesses, per-session remote runtimes, generic cross-harness approvals, harness-neutral add-ons, hosted access, and multi-user operation do not ship today.
