Save Task List for Reuse

Save the current session's task list so it can be restored in future sessions.

Session Context

• Session ID: ${CLAUDE_SESSION_ID}
• Active task directories: !ls -1t ~/.claude/tasks/ 2>/dev/null | head -5 || echo "none found"
• Current tasks in session: !ls -1t ~/.claude/tasks/ 2>/dev/null | head -1 | xargs -I{} ls ~/.claude/tasks/{} 2>/dev/null | head -10 || echo "no tasks"

Instructions

1. Find the current task list ID by checking ~/.claude/tasks/ for the most recently modified directory. List the directories sorted by modification time.

2. Verify the match — read the task files inside the directory and compare them to any tasks you know about from this session. Confirm you have the correct task list.

3. Log the session mapping — write the mapping to .claude/archon/sessions/:

   mkdir -p .claude/archon/sessions
   echo '{"session": "${CLAUDE_SESSION_ID}", "task_list": "<TASK_LIST_ID>", "saved_at": "'$(date -u +%Y-%m-%dT%H:%M:%SZ)'"}' \
     >> .claude/archon/sessions/task-lists.jsonl

4. Verify the SessionStart hook is installed — the project-level .claude/settings.json already includes a SessionStart hook that runs verify-task-list.sh on every session start. Confirm it's present by reading the file. If it's missing for some reason, add it back:

   {
     "hooks": {
       "SessionStart": [
         {
           "hooks": [
             {
               "type": "command",
               "command": ".claude/skills/save-task-list/hooks/verify-task-list.sh",
               "statusMessage": "Checking for restored task list..."
             }
           ]
         }
       ]
     }
   }

   Important: Merge — don't overwrite existing settings. If hooks or SessionStart already exists, append to the array. If the hook is already installed, skip this step.

5. Output the startup command for the user:

   To continue with this task list in a new session:
   
   CLAUDE_CODE_TASK_LIST_ID=<task_list_id> claude

   Explain: On startup, the SessionStart hook will verify the task list exists and show a confirmation message.

6. Show the current task summary so the user knows what's preserved (task subjects, statuses, and any dependencies).
