Lesson 1 of 1 in What You Pasted Into the Box
What You Pasted Into the Box
A context window is somewhere your secrets can go. Treat a paste as a disclosure and the rest follows.

Debugging a config problem, you paste the file. It has the database URL in it, and the API key, and the signing secret, because that is what a config file is. The answer comes back and the problem is solved.
The secret has now left your machine. Where it went, how long it stays, and who can see it are questions with different answers depending on the product, the plan, the settings, and the year.
Note
This course will not tell you what any provider retains. Those are claims about the world, they change, and a stale one here would be worse than none. What it will do is tell you the questions, and where the answer lives.
The questions worth having answers to
Is this conversation used to train anything?
How long is it stored, and can that be turned off?
Who inside the provider can read it, and under what process?
Does the answer change on a business plan versus a personal one?
What does the tool in my editor send, and when?
- Line 1Usually the setting people know about, and usually not the one that matters most.
- Line 2Retention is the one that decides whether a paste is a moment or a record. It is also the one most likely to differ from what you assume.
- Line 5The one nobody checks. An editor integration may send surrounding files, open buffers or the whole repository for context, and you never pasted anything at all.
Every one of those has a published answer for whatever you use. Find it once, write down what you found and the date, and put it where your team can see it — because in six months somebody will ask and the honest answer needs to be "we checked, here is when".
The habit that makes the questions matter less
What was pasted
DATABASE_URL=postgres://app:[email protected]:5432/prod
STRIPE_KEY=sk_live_51H...
CSRF_SECRET=9f2b1c4e...What was needed
DATABASE_URL=postgres://user:pass@host:5432/dbname
STRIPE_KEY=sk_live_REDACTED
CSRF_SECRET=REDACTEDThe shape of the file is what makes the answer useful. The values never were — nobody diagnosing a config problem needs your actual key, and that includes a human colleague.
Take care
If a real secret has gone into a context window, rotate it. Not because you know it was retained, but because you cannot know it was not, and rotation is cheap while the alternative is an assumption you are making on somebody else's behalf. This is the same rule as a secret committed to git: the fix is rotation, and everything else is cleanup.
That feels paranoid. It is a debugging session, not a data breach.
It is not a breach, and it is a disclosure — those are different words. You have told a third party something you did not have to tell them, and you cannot take it back. The question is never "was this malicious", it is "can I still say who knows this".
You pasted a live API key into a chat while debugging. What is the fix?
Tip
Keep a redacted example config in the repository, next to the real one in .gitignore. Then the file you reach for when you need help is already the safe one, and the habit costs nothing at the moment you are least inclined to think about it.
