Resume session with pruned context

Prune conversation history and auto-resume Claude Code session

Extending long-running Claude Code sessions by pruning token-heavy conversation history while preserving session context and resuming automatically.

• · Session ID (from environment or .claude/session-id.txt)
• · Current working directory (captured for background process)

• · Pruned conversation (35 messages retained)
• · Resumed session with history intact

• · npx claude-prune (session pruning)
• · claude CLI (session resume)
• · nohup / disown (background process survival)
• · kill command (process monitoring)

• · Claude Code environment has .claude/ directory
• · Session tracking enabled
• · claude and npx available in PATH

• · Session ID not found → background process cannot prune
• · cd to original directory fails → worker exits with error
• · Prune or resume command fails → logs to /tmp/prune-resume.log

• · Captures CWD before exit (critical for .claude/ folder discovery)
• · Uses nohup + disown for background survival
• · Error logging to /tmp/prune-resume.log for debugging
• · Automatic resume via claude -r SESSION_ID (user-transparent)
