using-todo

using-todo is a skill for Claude Code, Codex from JanYork/llm-wiki-cli. It costs 29 tokens per session (468 once invoked), scanned A, original, Apache-2.0.

A workflow for keeping deferred work in LWC, a task list system for coding agents. It covers recording, finding, changing, completing, cancelling, and reopening tasks.

In plain words
What is it for?
Use it to manage future coding tasks, reminders, and other work that needs to be handled later.
Why use it?
It prevents follow-up work from being forgotten when it cannot be done during the current task. It also requires checking a task before changing it.

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

using-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 2d 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.

What it actually says

Using LWC Todo

First run lwc config show. Continue only when todo.setting is enabled. A Skill trigger is not consent to enable Todo: when disabled, do not run Todo commands; explain that the user can opt in with lwc config set --todo enabled. A lifecycle Hook with a resolved agent_context includes only Todos explicitly tracked by that Agent context. Treat any Todo progress reminder for another context as unrelated and ignore it.

Use Todo only for independent future or deferred work. It is not the current execution plan and must never be converted to or from a Plan automatically.

  • Add: lwc todo add TITLE --tag TAG --cue TEXT --target-at RFC3339 --request-id ID.
  • After adding or explicitly claiming a Todo, bind it with lwc --scope project|global todo track TODO_ID --context CONTEXT_ID, using only the opaque ID from the current Hook's LWC_READINESS.agent_context. One context may track multiple Todos; never infer or copy another Agent's context.
  • Add one direct child with --parent TODO_ID. Parentage is organization only: it does not cascade completion, create dependencies, or turn children into Plan steps.
  • Discover: lwc todo list --limit 20, lwc todo list --parent TODO_ID, or lwc todo search QUERY --limit 20.
  • Inspect before mutation: lwc todo show TODO_ID; pass its revision with --if-revision.
  • Reschedule with todo update ... --target-at RFC3339; remove the time with --clear-target-at.
  • Finish or cancel with a specific result/reason; use reopen before changing a closed Todo.
  • Stop reminders with exact, idempotent todo untrack TODO_ID --context CONTEXT_ID; this removes only that context/Todo pair.
  • Use project/global for exact reads and writes. Use --scope all only for list/search.
  • On a revision or request conflict, reload and reconcile; never overwrite blindly.
  • Do not use --changeset with Todo commands.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
