Three related fixes: 1. lifecycle.go: Use gt mail delete instead of gt mail read to prevent lifecycle requests from accumulating. 2. handoff.go: Return exec claude command for respawn-pane instead of gt crew at which tries to attach to existing session. 3. handoff.md skill: Work without --cycle and -m flags, send mail separately. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
