A task-entry workflow that adds a new item to the appropriate configured to-do list after checking for similar existing tasks.

In plain words
What is it for?
Use it to record work items, choose between configured lists, assign a priority, and expand an existing task when a duplicate is found.
Why use it?
It helps prevent duplicate tasks and keeps work in the right list instead of leaving routing decisions to memory. It can also ask for missing task details before adding anything.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

todo-add scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Add To-Do Item

v1.1 — Adapted for public use

Add a new to-do item to the correct list with duplicate checking.

Instructions

1. Get the item details

If not provided by the user, ask:

  • What's the task? (brief description)
  • Any additional context?

2. Determine the correct list

Based on the item content, suggest the appropriate list using the routing table below. This table is an example — customize it to match your own lists and keywords.

Keywords/Topics Suggested List
config, settings, infrastructure, setup, tools Main
email, calendar, briefing, scheduling Work

Present your suggestion:

This sounds like a [Main/Work] item because [reason].

Suggested list: ~/Documents/todo.md
Priority: [High/Medium/Low]

Is this correct, or should it go elsewhere?

3. Check for duplicates

Read the target TODO file and scan for similar items. Check for:

  • Same keywords in item titles
  • Related tasks that might overlap
  • Items that could be expanded instead of duplicated

If potential duplicate found:

Potential duplicate detected:

Existing item: "[item title]"
Location: [file path], [priority level]

Options:
1. Add anyway (they're different enough)
2. Update the existing item instead
3. Cancel

4. Add the item

Once confirmed, add to the appropriate section with this format:

- [ ] **[Item title]**
  - [Context/details if provided]

Update the "Last updated" date in the file header.

5. Confirm

Added to [list name]:
  - [ ] **[Item title]**

Priority: [High/Medium/Low]

File Locations

  • Main: ~/Documents/todo.md

Add more lists by creating additional todo files and adding them here. For example:

  • Work: ~/Documents/todo-work.md
  • Personal: ~/Documents/todo-personal.md

Priority Definitions

Priority When to use
High Blocking progress, causing problems, or time-sensitive
Medium Would improve things but not blocking
Low Nice to have, someday

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
