Architecture brief v0.4.0 · monorepo overview

I got a question,
let me ask your Claude.

Half of what your team knows lives in one person's head — and nobody else can reach it. Your agent asks theirs, and gets the real answer, under permissions you and IT control.

An interactive walkthrough using real commands and representative output. The listener decrypts and verifies the request, resolves the task from the authenticated caller before their message enters any prompt, then checks tool attempts as the agent runs.

The answer is on someone else's machine.

Instead of interrupting a colleague, your agent asks theirs — and gets the answer from their real, current setup.

ONE CALL, START TO FINISH13.2s · 412 B
$ agentcall call ken "why did CI fail on main after the auth migration?"
ringing   @acme/ken
answered  agent running on ken's machine

The migration renamed session_token but the fixture still seeds the old column, so every auth test 500s on a fresh database. It passes locally because your dev DB was never re-seeded.

ALLOW Grep  src/auth/**
ALLOW Read  auth.fixture.ts
DENY  Read  ~/.ssh/id_ed25519  

Real commands, representative output. Timing is from one recorded call.

  • The person who wrote the migration left the company — their agent still remembers why.
  • The one engineer who knows why the workaround exists is on PTO.
  • Nobody wrote down why staging uses a different flag. Their agent does.

You decide what your agent answers.

One file per task: what it does, which tools it can touch, who can ask. That's the whole thing.

  • Callers can narrow the job. They can't pick a different one.
  • Anything outside that folder is refused, and logged.
  • If your company runs a relay, IT can cap what's offerable.

The permission model, in full

It costs them nothing but compute.

Their agent answers on their machine, on their own subscription. They're never interrupted and never asked to approve anything.

Pre-production, and specific about it.

Exactly what has and hasn't been run against a live call.

Live-tested
Claude

Run end to end against real calls, with the guard enforcing on every tool attempt.

Unverified
Codex

Built and unit-tested, never tried against a live call. Its read boundary is weaker.

Removed
The OS sandbox

Gone on purpose. Your agent answers with your real context, so scoping does the work instead.
