Sessions Panel

The Sessions panel lists the past Claude Code sessions for a channel and lets you resume any of them. Each agent run in a channel produces a session transcript on disk; the panel reads those and shows them newest-first with a one-line summary.

Overview

Component: app/src/components/panels/SessionsPanel.tsx

Sessions are read from GET /api/channels/{id}/sessions, which scans the Claude session store under $HOME/.claude/projects/<encoded-workdir>/*.jsonl (the workdir path is encoded the way Claude Code stores it). Each entry shows its session id and a short summary derived from the transcript, along with how long ago it ran.

Resuming

Selecting a session resumes that conversation — the next message continues from where it left off (claude --resume <session-id>), so context, file state, and history carry over. A filter box narrows the list, and + New starts a fresh session instead of resuming.

The empty state (“No sessions found”) simply means no agent has run in the channel yet.

Pruned transcripts

Claude Code deletes transcripts under $HOME/.claude/projects once they pass its retention window (cleanupPeriodDays, 30 days by default), while Loop pins a channel’s session id in the database and only replaces it after a successful run. A channel that sat idle for longer than the window therefore points at a file that no longer exists, and claude --resume fails the turn outright with No conversation found with session ID: … — every turn, permanently.

Loop checks for the transcript before it resumes:

• Agent runs and terminal panes drop --resume/--fork-session and start a fresh session when the file is provably absent, logging session transcript not found; starting a fresh session. A stat that fails for any other reason (unreadable home dir, permissions) is not treated as absence — the conversation is kept.
• New worktrees (the +wt button, ticket assignment, worktree tasks, thread forks) copy the source transcript into the worktree’s own project dir, because Claude keys sessions by working directory. When that copy fails, the new thread is left with no session id rather than inheriting one it cannot resume.

The conversation itself is not recoverable once pruned; the channel simply starts a new session on its next turn.
