fix(setup): auto-submit handoff context as Claude's first prompt#2741
Merged
Conversation
Interactive setup handoffs (mid-flow `?` escape and on-failure) spawned claude with all context in --append-system-prompt and no user message, so Claude sat at an empty REPL until the user re-explained themselves. Move the context into a positional prompt that auto-submits as the first user message: Claude starts orienting immediately, the context stays visible in the transcript, and it survives --resume. Also: - Share one session across all handoffs in a setup run: pin a generated UUID via --session-id on the first spawn, --resume it on later ones (stdio is inherited, so Claude's own id is never visible). - Switch --permission-mode from acceptEdits to auto. - Dedupe the two spawn blocks into spawnInteractiveClaude().

Problem
When the interactive setup flow hands off to Claude (the mid-flow
?help escape and the on-failure debug handoff insetup/lib/claude-handoff.ts), all the context was passed via--append-system-promptwith no user message. Interactive Claude only acts when a user message arrives, so the session opened at an empty REPL and the user had to re-explain a situation Claude had already been told about.Changes
--resume, which an appended system prompt would not. Matches the styleclaude-assist.tsalready uses for its non-interactive prompt.--session-id; later spawns--resumeit, so a second handoff keeps the context of the first. (stdio is inherited, so pinning our own id is the only way to find the session again.) Kept separate from claude-assist's-psession, which is primed with a strict REASON/COMMAND response format.acceptEdits→auto.spawnInteractiveClaude()helper.Testing
