Wrapper for launching Claude Code under detached pty (e.g. pty up) — bootstraps the session jsonl via --print on first run since detached pty interactive doesn't trigger persistence init. See https://gist.github.com/myobie/1505d47f9e805534d07ff721ca38557f for the bug context.

pty-claude-launcher.sh

#!/bin/sh
# pty-claude-launcher.sh — start or resume a pinned-id claude session
# under a detached pty (e.g. `pty up`), bootstrapping the transcript
# jsonl via `claude --print` on first run.
#
# Why: under detached pty + scripted interaction, claude's interactive
# init never creates `~/.claude/projects/<sanitized-cwd>/<uuid>.jsonl`,
# so a `--session-id <new-uuid>` fallthrough silently runs in-memory
# only and loses everything on shutdown. `--print` hits a different
# code path that always writes the jsonl. Subsequent `--resume <uuid>`
# under detached pty appends to the existing jsonl normally.
#
# This script is idempotent: the bootstrap fires only when the jsonl
# is missing. Existing agents whose jsonl already exists go straight
# to --resume — no re-bootstrap, no API token cost.
#
# Args forwarded to interactive claude, e.g.
#   "$HOME/bin/pty-claude-launcher.sh --dangerously-load-development-channels server:coord"
