Harness Bay

One inbox for every coding agent on your machines.

Cursor, Claude, Codex, and the rest pull into one bay. Read real transcripts locally — reply in each agent’s native session when you’re ready.

The jam

Your agents don’t share a driveway.

Work scatters across Cursor here, Claude there, Codex somewhere else. You lose the thread switching windows — and there’s no single place that answers “what’s waiting on me?”

  • Scattered sessions Seven tools, seven histories, zero shared inbox.
  • Context tax Every hop resets what you were looking at.
  • Blind spots Something finished overnight and you only find it later.

The bay

Every provider backs into the same dock.

Harness Bay finds the coding agents already on your machine and shows their real conversation history in one place. Observe first. Reply through each agent’s own native session where supported.

Who it’s for

Built for people who already have more than one harness.

If you live in more than one coding agent — or you’re about to — Harness Bay gives you one place to see what’s waiting across all of them. Cursor plus one CLI is enough; a full fleet is fine too.

Multi-agent operators

You bounce between tools on purpose and want one place to see what’s live across all of them.

Second-CLI curious

You live in Cursor but tried Claude or Codex — and now histories live in two worlds.

Local-first skeptics

You won’t send transcripts to someone else’s cloud just to get a nicer inbox.

Trust

It reads your agent transcripts — so the posture is absolute.

  • 100% local — no account, no telemetry.
  • Read-only by default — looking never implies writing.
  • Dispatch is opt-in — per agent, with the real command shown at consent.
  • Agent-agnostic — Cursor, Claude, Codex, and the rest are equal. No vendor owns the inbox.
