todo

todo is a skill for Claude Code, Codex from iamlukethedev/Hermes3D. It costs 12 tokens per session (892 once invoked), scanned A, a copy of todo, MIT.

A skill for maintaining a shared TODO list stored in the workspace. TODO items are small pieces of work that can be read, added, blocked, unblocked, or removed.

In plain words
What is it for?
Showing TODO items, adding new ones, marking them blocked or unblocked, and removing items from the shared list.
Why use it?
It keeps the current TODO state in a file instead of relying on memory from the conversation. This makes blocked work and outstanding items visible across sessions.

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 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 10d ago.

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.

Origin

This is a copy

95% identical to todo — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TODO Board

Use this skill when the user wants to manage a shared task list for the current workspace.

Trigger

{
  "activation": {
    "anyPhrases": [
      "todo",
      "todo list",
      "blocked task",
      "blocked tasks",
      "add to my todo",
      "show my todo"
    ]
  },
  "movement": {
    "target": "desk",
    "skipIfAlreadyThere": true
  }
}

When this skill is activated, the agent should return to its assigned desk before handling the request.

  • If the user asks from Telegram or any other external surface to add, block, unblock, remove, or read TODO items, treat that as a trigger for this skill.
  • The physical behavior for this skill is: go sit at the assigned desk, then perform the TODO board workflow.
  • If the agent is already at the desk, continue without adding extra movement narration.

Storage location

The authoritative task file is todo-skill/todo-list.json in the workspace root.

  • Always treat that file as the source of truth.
  • Never rely on chat memory alone for the latest task state.
  • Create the todo-skill directory and todo-list.json file if they do not exist.

Required workflow

  1. Read todo-skill/todo-list.json before answering any task-management request.
  2. If the file does not exist, create it with the schema in this document before continuing.
  3. After every add, remove, block, or unblock action, write the full updated JSON back to disk.
  4. If the file exists but is invalid JSON or does not match the schema, repair it into a valid structure, preserve any recoverable items, and mention that repair in your response.
  5. If the user request is ambiguous, ask a clarifying question instead of guessing.

Supported actions

  • Add a task. Create a new item unless an equivalent active item already exists.
  • Block a task. Change the matching item to status: "blocked". If the task does not exist and the request is clear, create it directly as blocked.
  • Unblock a task. Change the matching item back to status: "todo" and clear blockReason.
  • Remove a task. Delete only the matching item. If multiple items could match, ask for clarification.
  • Read the list. Summarize tasks grouped into TODO and BLOCKED.

Changes

What this file has done since we first saw it

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.
