What it does

Find ways to open up meaningful free time in a connected Google Calendar. Use when the user wants to clear up their day, make room for focus time, create a longer uninterrupted block, or see the smallest set of calendar changes that would give time back.

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.

10## Relevant Actions

12- Use search_events to map the day's current fragmentation and identify movable candidates.
13- Use read_event or read_event_all_fields when one candidate meeting needs a closer look before proposing a move.
14- Use create_event when the user explicitly wants a temporary hold or focus block once the target slot is grounded.
15- Use update_event, update_event_series, or update_event_following only after the proposal is clear and the correct scope of change is grounded.

17## Workflow

191. Start by identifying the target: today, tomorrow, this afternoon, a specific day, or a broader window. If the user already gave a concrete window or duration, work inside it before asking follow-up questions.
202. Optimize for contiguous free blocks, not raw free-minute totals.
213. Identify which meetings are likely fixed and which are more movable before proposing changes.
224. If the user explicitly wants a temporary hold or focus block rather than a reschedule plan, choose the best qualifying free slot and create the hold once the slot is clear.
235. Look for the smallest edit set that creates a meaningful uninterrupted block.
246. Prefer solutions that reduce fragmentation across the rest of the day, not just one local gap.

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.

≈80
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
620
on trigger
The instruction body and 1 supporting file, read only when the skill fires.
0.35%
of a 200k window
Ten skills this size would take about 4% of the window before you open a file.
050k100k150k200k context window

700 tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Small enough to keep loaded permanently without thinking about it.

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

2 files, 2.8 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in. 2 files of its source are not in the download — listed after these, with why.

  • SKILL.md2.5 kB
  • agents/openai.yaml0.3 kB

Not in the download

Not carried is a type a skill download does not hold. Take them from its source.

  • assets/icon.pngnot carried
  • assets/logo.pngnot carried
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the download is 2 files — not the whole of its source: 2 files are left out. They are listed under the files, with why.

Install

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

# Google Calendar Free Up Time · 700 tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/google-calendar-free-up-time/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/google-calendar-free-up-time" ] && { [ ! -e .claude/skills/google-calendar-free-up-time ] || { mv .claude/skills/google-calendar-free-up-time "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/google-calendar-free-up-time" .claude/skills/ && echo "Installed .claude/skills/google-calendar-free-up-time"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add openai/google-calendar-free-up-time

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/google-calendar-free-up-time/ 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/google-calendar-free-up-time/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/google-calendar-free-up-time" ] && { [ ! -e ~/.claude/skills/google-calendar-free-up-time ] || { mv ~/.claude/skills/google-calendar-free-up-time "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/google-calendar-free-up-time" ~/.claude/skills/ && echo "Installed ~/.claude/skills/google-calendar-free-up-time" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/google-calendar-free-up-time/ 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. Not in this download: 2 files of its source (the full list, and why). Take them from its source.

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.
