Every message in a chat goes back to the model with the next one, so a long thread costs more each turn. A brief lets you start clean and keep your place. ### Who it suits People who keep one AI conversation going for hours or days, and people who pass a thread on to someone else. Who uses it, and how | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Software | Developers in long Claude Code or Cursor sessions | Compact a session that has grown slow and carry on in a fresh one | A developer whose debugging thread has run for hours compacts it and carries on in a new chat that answers faster | | Freelance and consulting | Freelancers and consultants who hand work over | Turn a client thread into a handover note | A freelancer closing out a project pastes the brief into the handover note for the next person | | Product and project teams | Team leads | Keep what a long planning chat decided | A team lead turns a long planning chat into a brief and posts it where the team keeps its decisions | | Research and writing | Anyone who tries more than one model | Start a second model from where the first one stopped | Someone moving from one model to another starts the second with the brief instead of the whole history | If your chats are short and start fresh each time, you do not need it. ### Where to use it In any AI chat, on any conversation you can copy. - Any AI chat: where you paste the skill’s prompt and the thread - ChatGPT, Claude or another chat app: a thread that has grown long and slow - Claude Code: a session near its context limit, where file names and commands have to survive word for word When to compact | Moment | Why then | | --- | --- | | Replies slow down and cost more | Every message sends the whole thread again | | A session nears its context limit | Paste the stretch that holds the decisions while the model can still read it | | You stop for the day | The next session starts from the brief instead of a long reread | ### How to set it up What you need first: - Where it runs: any AI chat - A key: none - An install: none 1. Sign in to Mindket and press Get it on this listing. 2. In your Mindket account, View shows the prompt to read and copy. This page shows it too. 3. Keep it where you can paste it again: a saved prompt in your chat app, if it keeps them, or a note. ### How to use it Paste the skill’s prompt into an AI chat and put the conversation where it says {{input}}, or the stretch of it where the decisions were made. Then open a new chat and send the brief as your first message. ```text ``` You paste a long chat in place of {{input}} → The model keeps the goal, decisions, facts and open items → A brief of at most 200 words comes back → You start a new chat with the brief ### Example You paste a long debugging chat about a login test that fails on every second run, with the skill’s prompt above it. You get a brief of at most 200 words, in five parts: What the brief holds | Part | What it keeps from the chat | | --- | --- | | Goal | What you are trying to do | | Decisions | What has been decided so far | | Facts and numbers | The ones that matter | | Open | What is still unsolved | | Next step | Where the new chat picks up | File names, commands and code names appear as they were written, so the test’s file and the command that runs it come through unchanged. ### For newcomers and experts **If you are new.** An AI chat rereads the whole conversation every time you send a message. That is why long chats slow down and cost more. This skill writes the short version of where things stand. Try it on a chat you have kept going for a while, and see whether the brief alone gets a new chat up to speed. **For experts.** It is one prompt with a hard cap of 200 words and five fixed parts. Names, commands and code identifiers are kept by instruction, not by parsing. The compression is lossy and the model decides what to drop, so the reasoning behind a decision may not survive. Keep the original thread if you might need to audit it. When a chat is longer than the model can read, paste only the stretch that holds the decisions. ### Good to know - What it keeps: only what is in the text you paste - What it drops: a reason or a number left out of the brief is gone from the new session, so read the brief before you rely on it - Privacy: it never reads the page you have open ## The prompt ```text Compress this conversation into a brief a new AI session can continue from, in at most 200 words: the goal, the decisions made, the facts and numbers that matter, what is still open, and the next step. Keep file names, commands and code names exactly as written. {{input}} ``` Put your question or text where it says {{input}}. ## Intro videos - [Context compactor intro video 1](https://www.youtube.com/watch?v=eW3oTyfeWZ0) - [Context compactor intro video 2](https://www.youtube.com/watch?v=riN4S9AoaB0) - [Context compactor intro video 3](https://www.youtube.com/watch?v=I1EGbrH5Xdk) ## Get it - [Get it on your Mindket account](https://account.mindket.com/account/?product=mindket#/market/7c0d6bb6-e854-43fa-bcaf-01c950347fa9) - [Its page on Mindket](https://mindket.com/p/7c0d6bb6-e854-43fa-bcaf-01c950347fa9)
