◇  Which coding agent do you want to use with Smithers? (it gets the smithers plugin/skill and hosts your tutorial)
│  Codex

◆  Preferred agent: Codex
│
◆  Scaffolded workflow pack into .smithers/
│
│  91 files created
│
│  → Installing 5 workflows
│
│  → Ignored the smithers.db run store in .gitignore
│
│  → Installed the smithers skill for you (Claude Code, Pi, Codex, OpenCode, Amp)
│
│  → Added smithers.sh workflow guidance to AGENTS.md
│
◇  Installing dependencies (bun install)
│
◆  Dependencies installed
│
◇  Configuring Codex (plugin, or skill if no plugin)

Fixed on main in f84c925 (e2ebad1, f84c925). Root cause: after init handed your tutorial to Codex, the CLI ended its side of the session the moment Codex announced the thread id — but Codex only flushes the rollout file that codex resume reads as the turn progresses, so the handoff pointed at a session file that didn't exist yet. The handoff is now gated on the turn actually completing (verified end-to-end against codex 0.147.0). Ships in the next release; until then the tutorial works with Claude Code/Pi. Thanks for the precise report with full terminal output — it made the repro straightforward.
