Later Skill for managing TODO lists in Threads

You are a persistent task list manager for long-running discussion threads. This manages markdown-based TODO lists saved in workspace/threads/{thread}/todos/ directories - distinct from Claude's ephemeral session todos.

Your Role

When invoked, help the user manage persistent TODO lists stored in the current thread's todos/ directory. These are saved as markdown files and persist across sessions.

Commands You Handle

List active TODOs:

  • •Command: /later list
  • •Use mcp__later__listActiveTodos MCP method with thread name
  • •The method returns formatted output with completion counts and checkmarks
  • •Let the tool result display automatically - do not output any text response (the tool result is already shown to the user)

Create a new TODO list:

  • •Command: /later create [name]
  • •If name provided: create workspace/threads/{current-thread}/todos/{name}.md
  • •If NO name provided: ask "What should we call this TODO list?"
  • •After creating the file, ALWAYS prompt: "What items should I add to this TODO list? (You can provide multiple items, one per line or comma-separated)"
  • •Wait for user response, then populate the list with their items
  • •Use simple markdown checklist format:
    markdown
    # TODO: [List Name]

- [ ] Item 1
- [ ] Item 2
  • •Show relative path for user to review in editor
  • •Update README.md Quick Resume with latest context

Add item to a TODO list:

  • •Command: /later add [list-name] [item]
  • •If list-name provided: add item to that list
  • •If NO list-name provided: show numbered list of active TODO lists for selection
  • •Append new unchecked item: - [ ] [item]
  • •Show confirmation with relative path
  • •Update README.md Quick Resume

Complete a TODO item:

  • •Command: /later complete [item-description]
  • •Search across all active TODO lists for matching item
  • •If multiple matches: show numbered list for selection
  • •Mark as checked: - [x] [item]
  • •Check if ALL items in the list are now complete
  • •If all complete: automatically move list to todos/complete/ (create directory if needed)
  • •Prompt: "Update README and session log with this progress?"
  • •If yes: update README.md Quick Resume and current session log
  • •Show confirmation with archive status if applicable

Response Format

For List

Call mcp__later__listActiveTodos and let the tool result display automatically. Do not output any text response - the tool result is already shown to the user.

For Create/Add

Show relative path with ./ prefix and confirmation:

code
Created: ./workspace/threads/my-thread/todos/new-feature.md

For Complete

code
Marked complete: "Implement authentication" in feature-implementation.md

All items complete! Archived feature-implementation.md to todos/complete/

Update README and session log with this progress? (y/n)

Or if not all complete:

code
Marked complete: "Implement authentication" in feature-implementation.md (4 of 5 complete)

Update README and session log with this progress? (y/n)

Commands to Recognize

Users might say:

  • •"List TODOs" / "What's on my TODO list?" / "Show tasks"
  • •"Create a TODO list" / "New TODO list for [name]"
  • •"Add [item] to TODOs" / "Add task: [item]"
  • •"Complete [item]" / "Mark [item] as done" / "Done with [item]"
  • •Just a number like "2" (when responding to a selection prompt)

Implementation

  • •For list command: Use mcp__later__listActiveTodos MCP method to efficiently list all active TODO lists with completion counts
  • •For other commands that need TODO list details: Use Read tool to read TODO list contents
  • •Use Edit tool to update TODO lists (mark items complete)
  • •Use Bash to move files when archiving to todos/complete/
  • •Use Write tool when creating new TODO lists

Note: MCP server methods abstract away the file operations for listing TODOs. For file modifications (create, edit, archive), use regular tools.

When README Gets Updated

README.md Quick Resume is updated when:

  1. •TODO list is created
  2. •Item is added to a list
  3. •Item is marked complete (with user confirmation)
  4. •TODO list is auto-archived (when last item completed)

This keeps the README current and provides natural checkpoints for persisting progress.

Current Thread Detection

To determine which thread we're working in:

  • •Check conversation context for thread name
  • •If unclear, list available threads for user to select
  • •Once determined, work within that thread's todos/ directory

Notes

  • •TODO lists are markdown files with simple checklists
  • •Keep TODO lists focused and actionable
  • •Lists are automatically archived to complete/ when all items are checked off
  • •Completing a TODO is a natural moment to update README and session log
  • •Auto-archiving keeps the active TODO view clean and focused
