Put disagreement
to work.
ContextRelay puts Anthropic's Claude Code and OpenAI's Codex in one working session—so they can hand off, push back, revise, and leave a durable trail.

Join the work. Don't hijack it.
A one-way call ends with an answer. ContextRelay keeps a bidirectional channel open for the objection, the correction, and the evidence that changes the plan.

Keep the follow-up durable until the receiver is ready.

Fail explicitly and send nothing when delivery would be wrong.
Symmetric recovery
Bad timing does not become lost work.
When either agent reaches a usage limit, ContextRelay estimates the reset. The default mode notifies you. In resume mode, work ContextRelay delivered—and observed fail definitively—can be captured and re-sent after the window resets.
Ambiguous timeouts stop here. They never become a second copy through a slower path.

Local by architecture
The conversation leaves receipts.
The interface can close. The shared record remains: messages, handoffs, notes, artifacts, audit events, and final decisions written locally for both agents to inspect.

Engineering evidence
Proof has a build log.
Every release crosses the full suite and security gates before npm. The process is inspectable, and the threat model says plainly what ContextRelay does—and does not—protect.
