What it does

Schedule a one-shot Claude Code task to start at a specific wall-clock time and run headless/unattended, so work that has to happen while the user is asleep or away actually happens. Two main uses. First, unattended watch-and-wrap-up on remote work — wake at a set time, check whether a cloud/GPU run finished, pull the results back, verify them, then destroy the instance so it stops billing. Second, moving heavy or batch work into an off-peak window to spread load across the rolling usage limits.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

6# action — 排程在指定時間才啟動的 headless 任務
7
8把一個任務 park 起來,到指定的**絕對時鐘時間**才用 claude -p 在背景 headless 跑(預設無人值守、skip permissions)。它讓「人不在的時候仍然要發生的事」真的會發生——半夜把跑完的雲端實驗收回來並關機停止計費、清晨把粗重工作挪進離峰額度視窗。
9
10這是 autocontinue 的**主動版**:autocontinue 是撞到 limit 後等 reset 自動接續(被動);action 是事先排到指定時間才開始(主動)。兩者可疊加——排程跑的 job 若中途撞 limit,全域安裝的 autocontinue StopFailure hook 會接手復活。
11
12## 鐵律:跨越 session 的事一律排程,不准口頭承諾
13
14使用者要求任何在**本次對話結束之後**才發生的事——「等它跑完再抓回來」「明天早上八點看一下」「跑完就把機器關掉」——都必須排成 action job。
15
16session 在那個時間點**不存在**。在對話裡回「好,我到時候會處理」「我會持續監控」是空頭支票:終端機關掉、電腦鎖上、context 被清掉,承諾就隨之消失,而遠端實例會繼續計費到有人發現為止。in-session 的 background bash、sleep、Monitor 全部同樣會死。
17
18判準只有一句:**這件事要發生的時刻,這個 session 還在嗎?**不在就排程。

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈260
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
2,915
on trigger
The instruction body and 6 supporting files, read only when the skill fires.
1.6%
of a 200k window
Ten skills this size would take about 16% of the window before you open a file.
050k100k150k200k context window

3.2k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Middling. Fine to keep on in a project where you use it weekly, worth unloading in one where you never do.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

7 files, 32.3 kB on disk. Mostly text — the instructions the model reads — with 5 scripts in it that your client would run only if the instructions tell it to.

  • SKILL.md8.1 kB
  • install.sh2.9 kB
  • README.md4.6 kB
  • uninstall.sh0.5 kB
  • bin/action.py4.6 kB
  • bin/action_common.py5.2 kB
  • bin/action_runner.py6.4 kB
What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 5 scripts beside the text, so the bundle is 7 files you can review in full before installing.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Scheduled Headless Tasks · 3.2k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/scheduled-headless-tasks/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/scheduled-headless-tasks" ] && { [ ! -e .claude/skills/scheduled-headless-tasks ] || { mv .claude/skills/scheduled-headless-tasks "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/scheduled-headless-tasks" .claude/skills/ && echo "Installed .claude/skills/scheduled-headless-tasks"

npx mcprush@latest skill add chenlu-hung/scheduled-headless-tasks

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/scheduled-headless-tasks/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/scheduled-headless-tasks/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/scheduled-headless-tasks" ] && { [ ! -e ~/.claude/skills/scheduled-headless-tasks ] || { mv ~/.claude/skills/scheduled-headless-tasks "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/scheduled-headless-tasks" ~/.claude/skills/ && echo "Installed ~/.claude/skills/scheduled-headless-tasks" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/scheduled-headless-tasks/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as action in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, scheduled-headless-tasks.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
