Relayvora hands an unfinished Claude Code or Codex session to the other agent with a verified 4K-token briefing
Shown on HN Nov 1, relayvora handoff --from codex --to claude --verify auto --confirm reads your latest session, captures diffs and commits, runs the project's own tests, and launches the other agent with a briefing that labels each fact as observed, user, agent-reported or inferred. It's local-only and pre-alpha, and the author says it saves context on big sessions, not money on small ones.
