Compose
Connect agents, tools, data, and interfaces through deliberate seams.
A11 / Builders
Build the system behind the promise.
A11 architecture patterns turn agent concepts into inspectable product surfaces: secure bridges, typed events, transaction boundaries, audit records, and release gates.

Builder layer
From ambitious system to working surface.
Good architecture makes the next action obvious. Builders use explicit seams between interface, service, data, identity, evidence, and release decisions.
Protect
Keep credentials server-side and restrict state-changing operations.
Execute
Perform authorised, version-valid, reversible operations.
Verify
Distinguish a working system from a plausible demo.
Delivery discipline
Every implementation should leave a trail.
The trail is not paperwork added after the fact. It is the set of records that lets the owner understand what changed, what passed, and what still needs authority.
- Typed contracts make service boundaries inspectable.
- Idempotency makes safe retry behaviour explicit.
- Validation commands create repeatable evidence.
- Handoff notes preserve the next decision.
