When should I use The Call Booker?

A warm reply needs to turn into a booked meeting fast, without four emails of back-and-forth. That's the diagnostic trigger. Once installed, ask Claude for the outcome ("book, reschedule, and confirm a meeting in one pass") and the skill kicks in automatically.

How does The Call Booker work under the hood?

The Call Booker is part of the SDR pack in Sid Chaudhary's gtm-skills repo. When invoked, Claude reads the SKILL.md, pulls your shared product-context (ICP, brand voice, scoring model), and produces a structured output. No prompt engineering on your side.

Do I need Claude Code to run The Call Booker?

Claude Code is the fastest path since it auto-loads local skill folders. The same SKILL.md also runs in Claude Desktop and claude.ai Projects - upload the zip in Capabilities. See the install options below for both paths.

How is The Call Booker different from just prompting Claude?

A skill is a folder with a SKILL.md file plus reference material - real methodology, frameworks, and benchmarks Claude loads on demand. A prompt is text you paste every time. With The Call Booker installed, you ask for what you need in plain language and Claude runs the right process without you re-explaining it.

Q: Is The Call Booker really free?

Yes. The full gtm-skills repo is MIT licensed on GitHub. Clone it, fork it, modify it. Running the install command (npx skills add sidchaudhary/gtm-skills/skills/sdr/the-call-booker) pulls it straight from GitHub into your project's .claude/skills/ folder. No signup, no build step, no gated tier.

SDR skill by Sid Chaudhary

The Call Booker

Write the four messages that get a warm conversation onto a calendar and keep it there.

How to run

Ask the user for:

The conversation so far: pasted, so the booking message can reference it naturally
Availability: two real time slots, or a booking link, or both
Meeting length: in minutes
Voice profile: if the user has one from a voice-capture skill, use it; otherwise keep the tone direct and low-friction

Output format

Write all four:

The booking message — under 40 words. Offer two specific named times and the booking link. Two named times convert better than a bare link, because named times don't ask the prospect to do the work of checking their own calendar first.

The reschedule — for when neither time works. Warm, no friction, no implied inconvenience.

The confirmation — sent once booked. Three bullets on what the call will cover, plus one question for the prospect to think about beforehand. The question is what prevents a no-show, not just politeness.

The day before — one line. Confirms the time and gives an easy out. An easy out lowers no-show risk, it doesn't invite one.

Rules

Never offer more than two time options. Three creates a decision the prospect has to make instead of a choice they can make instantly.
Never write "let me know what works." That puts the scheduling work back on the prospect.
The confirmation's pre-think question must be specific to what came up in the conversation, not generic ("what should we prioritize on the call?" beats "any questions before we chat?").

Quality check before returning

Before returning the output, verify:

Does the booking message contain exactly two named times plus the link, under 40 words?
Does the confirmation have exactly three bullets and exactly one question?
Is the day-before message one line with an actual easy out, not just a reminder?
Does any message contain "let me know what works" or an equivalent hand-off-the-work phrase? If so, rewrite it.

If any check fails, rewrite the relevant message before returning.

Part of the SDR pack

This is one of 12 SDR skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. 12 best Claude Code skills for SDRs walks the whole pack in the order the skills actually chain.

Install

Two ways to run it.

Pick your Claude surface. Both paths take under a minute.

Prefer one command? npx skills add sidchaudhary/gtm-skills installs the whole set via the community skills CLI. If you'd rather not run a third-party CLI, use either path below to install the ZIP directly.

claude.ai or Claude Desktop

Upload as a zip in Capabilities

Paid plan

Open Settings, then Capabilities
Turn on code execution if it isn't already on
Upload the .zip you downloaded

Requires a Pro, Max, Team, or Enterprise plan. Not available on the Free plan.

Claude Code

Drop the folder, it auto-loads

Any plan

Unzip the download
Drop the folder into ~/.claude/skills/ (or .claude/skills/ in a project)
Claude Code finds it automatically

$ ls ~/.claude/skills/

Questions about The Call Booker

Everything you need before installing, plus how the skill actually behaves once Claude picks it up.

Writes the booking message, reschedule, confirmation, and day-before reminder that gets a warm lead onto a calendar. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
