ChatGPT skills, ready to upload
Every kit gives you a ChatGPT Project for the agent and upload-ready skills for its job. No GPT builder, no prompt writing.

Skills teach ChatGPT how to do a specific job the same way every time: chase an invoice, write a morning briefing, qualify a lead. Each skill is a small folder with a SKILL.md file inside, zipped up and uploaded once.
OpenAI is retiring custom GPTs on 11 December 2026 and moving them to plugins, which bundle skills and connected apps. Our ChatGPT kits never used a GPT: the agent lives in a Project (works on every plan) and its job lives in Skills. So nothing changes for you when GPTs go.
How to create a ChatGPT skill
- Make a folder named after the job, for example
invoice-reminder. - Inside it, add a
SKILL.mdfile: a short header with anameand adescriptionthat says when to use it, then the steps in plain English.
---
name: invoice-reminder
description: Use to chase an unpaid invoice. Drafts a polite
reminder that gets firmer each time. Never sends without asking.
---
# Invoice reminder
1. Find the invoice number, amount and due date.
2. Check how many reminders have gone out already.
3. Draft the next reminder in the user's tone...
- Zip the folder, then in ChatGPT open Skills → Create → Upload from your computer and upload the zip.
- In a chat, ask for it by name: "Use the invoice-reminder skill on this list."
Tips: start the description with "Use when…" so ChatGPT knows when to reach for it, keep one job per skill, and put the rules that must never break inside the skill itself.
ChatGPT skills examples from our kits
Real skills from KitMyAgent agents, each delivered as an upload-ready zip:
- reminder-ladder (Chase, the invoice chaser): reminders that firm up step by step, from friendly nudge to final notice.
- cash-forecast: what money is expected in over the next 4–8 weeks, with a realistic version that allows for late payers.
- morning-handover (Hollis, the night-shift assistant): one short note each morning on what's done and what needs you.
- enquiry-triage (Rivet, the trades office): works out what a new enquiry needs and drafts a reply asking for exactly that.
- red-flag-hunter (Sterling, the investor's desk): looks for warning signs in results, reports and news. Research only.
- scam-alert (Vigil, the threat-intel agent): checks a suspicious email or text and writes a short staff warning.
- travel-butler (Ashworth, the butler): itinerary, packing list and a one-page trip sheet.
Moving from a custom GPT to skills
Custom GPTs retire on 11 December 2026. To move one over: paste its instructions into a Project (works on every plan), then turn each repeated task it did into a skill. To share it with a team, bundle the instructions and skills as a plugin. Our ChatGPT install guide covers all three.
Install in three steps
- Create a Project named after your agent and paste
project-instructions.mdinto its custom instructions. - Open Skills, then Create, then Upload from your computer, and upload each zip from
chatgpt/skills/. - Start a new chat in the project and ask for a skill by name.

Advanced agents: a full set of skills
These agents come with hand-written skills for their whole job, on top of the agent itself. 3 downloads each.
- Aged debt list: Use to answer "who owes me money?". Builds an aged list of unpaid invoices (current, 1–30, 31–60, 61–90, 90+ days overdue) with totals, the oldest first, from the user's invoices or accounting export.
- Cash forecast: Use to show the user what money is expected in over the next 4–8 weeks, from unpaid invoices and agreed payment plans, with a realistic version that allows for the usual late payers.
- Late payment interest: Use when a UK business customer pays late and the user wants to know what they can claim. Explains statutory late-payment interest and fixed compensation, and works out the figures. General information only.
- Payment plan: Use when a customer says they can't pay in full. Drafts a fair payment-plan proposal (instalments, dates, what happens if one is missed) for the user to approve, and then tracks it.
- Reminder ladder: Use to chase an unpaid invoice. Drafts reminders that firm up step by step (friendly nudge, reminder, firm, final) so the user never has to write the awkward one. Never sends without approval.
- Appointments and reviews: Use to draft appointment reminders the day before a visit or job and, after a job is complete and paid, a polite request for a review. Also drafts replies to reviews.
- Deposits and payments: Use to track deposits and stage payments on jobs and to draft polite payment requests and reminders. Knows which jobs are waiting on money before work can start.
- Enquiry triage: Use when a new job enquiry arrives (email, message, website form). Works out what's being asked, what's missing to quote, and drafts a friendly reply asking for exactly that. Never promises dates or prices.
- Job tracker: Use to keep one up-to-date list of every job from enquiry to paid, and to answer questions like "what's on next week?" or "which jobs are waiting on materials?".
- Quote from notes: Use to turn site-visit notes, photos or a voice note into an itemised quote using the user's own price list. Flags anything not on the list instead of guessing.
- Errands and admin: Use for household and personal admin: booking appointments, comparing options, filling in forms, chasing refunds and organising paperwork. Prepares everything and asks before any booking, payment or message goes out.
- Evening turndown: Use in the evening (or on "Anything for tomorrow?"). Prepares the user for tomorrow: an early-start warning, what to have ready, loose ends from today, and a calm sign-off.
- Morning briefing: Use each morning (or on "Good morning"). Delivers a short, understated briefing of the day: diary, weather, anything urgent, and one thing worth remembering, in the butler's voice.
- Occasions keeper: Use to remember birthdays, anniversaries and occasions, suggest thoughtful gifts within a budget, and remind the user in good time to buy, post or book.
- Travel butler: Use when the user is travelling. Builds the itinerary, a packing list, check-in reminders and a one-page trip sheet with key times, addresses and confirmation numbers.
- Approvals queue: Use whenever an action needs the user's permission. Keeps one numbered queue of pending approvals, lets the user approve in bulk ("yes to 1, 3 and 5"), carries out only what was approved and reports back.
- Follow up tracker: Use to keep track of promises and loose ends: replies the user is waiting for, things they promised others, and deadlines. Reminds the user before things slip and drafts polite chasers for approval.
- Interrupt rules: Use whenever something new arrives while the user is busy or off duty, to decide whether to message them now, save it for the morning brief, or say nothing. Follows the user's own three-bin rules and quiet hours, and flags anything it isn't sure about.
- Morning handover: Use first thing each morning (or when the user asks "what happened overnight?"). Produces one short handover note covering what's done, what needs their OK, what was held back and today's priorities.
- Overnight triage: Use for the overnight or out-of-hours sweep of email and messages. Sorts everything into urgent, needs-your-OK, done and FYI, drafts the replies, and holds anything risky for the morning. Never sends without approval.
- Running costs review: Use on the first Monday of each month (or on "check my agent costs") to review every background and scheduled job the user runs, what it cost and whether it earned its keep, and recommend what to keep, slow down, merge or switch off.
- Weekly wrap: Use at the end of the week. Summarises what got done, what is still open, money in and out if tracked, and the top priorities for next week, in one page.
- Company fact sheet: Use when the user names a company or ticker and wants to understand it. Researches the business and its numbers and fills in a one-page fact sheet with sources and dates. Research only, no buy or sell view.
- Earnings day brief: Use before or after a company's results. Before, it sets out what is expected and what would surprise. After, it compares the results with expectations and the company's own guidance, in plain English. Research only.
- Eight schools check: Use when the user wants to look at a company through famous investing approaches. Runs eight checklists (principles associated with Buffett, Graham, Lynch, Greenblatt, Terry Smith, Burry, Eisman and Piotroski) and shows an agreement map. Education only, no score and no verdict.
- Investment journal: Use when the user buys, sells or is thinking about a share, or sets their own investing rules. Keeps a journal of their reasons and their own trim/exit rules, and reminds them of both when prices move. Never makes decisions for them.
- Red flag hunter: Use when the user shares results, an annual report, a news story or a ticker and wants warning signs checked. Looks for debt creep, cash that doesn't match profits, dilution, accounting gaps and hype. Lists findings with sources; never gives a verdict.
- Weekly watchlist review: Use once a week (or when asked) to review the user's watchlist and holdings. Summarises price moves, news, results dates and any of the user's own rules that were triggered. Facts only, under one page.
- Cve triage: Use when the user names a vulnerability (a CVE number, a product flaw in the news, or a vendor advisory) and asks whether they need to act. Works out whether it is exploited, whether the user is affected, what the fix is and how urgent it is.
- Daily threat briefing: Use when the user asks for their threat briefing, security news or "anything I need to worry about". Checks official advisories and reputable security news, keeps only what affects the user's stack profile, and writes a short ranked briefing with sources.
- Hacker trend watch: Use when the user asks what hackers are up to, for a weekly security round-up, or about threats to their sector. Summarises the week's main attack trends (ransomware, phishing, account takeovers, supply-chain attacks) in plain English, focused on businesses like the user's.
- Incident first hour: Use when the user thinks they may have been hacked or scammed (a strange login, ransom note, encrypted files, money sent to the wrong account, a staff member who clicked a bad link). Calmly walks them through the first hour of defensive steps and gets the right humans involved.
- Scam alert: Use when the user wants to warn staff about a current scam, or forwards a suspicious email, text or call and asks if it's genuine. Writes short staff alerts about live scams, and checks suspicious messages safely as text, without clicking anything.
- Stack profile: Use first, and whenever the user mentions new software, devices or services. Builds and keeps a short profile of the technology the user's business actually runs, so every briefing can be filtered to what affects them.

Questions
Do I need a paid ChatGPT plan?
The Project part works on every plan. Uploading skills needs a plan with Skills. If yours doesn't have them, the agent still works from the project instructions.
What happens to my custom GPTs on 11 December 2026?
OpenAI moves them to plugins. Our kits use a Project plus Skills instead of a GPT, so they are not affected. The install guide also shows how to bundle your agent as a plugin to share with a team.
Can I edit a skill?
Yes. Unzip it, edit the SKILL.md in any text editor, zip the folder again and re-upload. It is plain text you own.
What is the difference between ChatGPT skills and custom instructions?
Custom instructions (in a Project) say who the agent is and the rules it follows in every chat. Skills say how to do particular jobs and are used when a request matches. A good agent has both, which is what every kit includes.
What are the best ChatGPT skills to start with?
The boring, repeated jobs: chasing invoices, a morning summary, sorting enquiries, turning notes into quotes and tracking follow-ups. They save time from day one and are low risk when the skill drafts and you approve.
Do ChatGPT skills work in Claude or Gemini?
The SKILL.md format is shared, so the same skill folders work in Claude, Claude Code, Codex, OpenClaw, Hermes and Gemini. Every kit includes ready-made versions for each.
