Most skills keep a set of pages: one per person, one per company, one per
meeting. Two skills can keep the same set. That is usually fine — one adds a
dated line about a bug a customer reported, the other adds what the customer
said on a call, and neither touches the other's work.

It stops being fine when one of them **rewrites** a page instead of adding to
it. Then the second skill's run replaces what the first one put there, and
until now nothing said so.

## What you see

Set up a skill that would write over another one's pages and GBrain shows you
a page first. It names the skill already in the workspace, says what it does
with those pages, and says what happens to them:

    <img src="/docs/skills/page-conflict.png" width="1280" height="700" loading="lazy" alt="A GBrain page headed “Set up Learn How I Talk here?”. Under it: “Reads the email that matters into memory, files the people and companies mentioned, and learns how you write to each kind of person. It writes the same person pages as Person Research, which is already in this workspace — and it rewrites them rather than adding to them.” Then a section headed “What confirming will do” with one line: “Person Research rewrites person pages rather than adding to them. When it next runs on a page, what Learn How I Talk added to it goes with it.” Then “What stays”: the work already on those pages stays until a rewrite touches it, and if you want both, set this up and don't ask Person Research about the people you keep in those pages. Two buttons: Not now, and Set it up anyway.">

Press **Set it up anyway** and the skill is set up as usual, in a conversation
of its own. Press **Not now** and nothing changes.

## Where the warning comes from

Every skill says which pages it keeps, and which of them it rewrites rather
than adds to. That statement is part of the skill, so what the page tells you
is read from the skills themselves rather than guessed at from their names.

A warning appears when one side rewrites what the other writes. Two skills
that both only add to a page never warn, because they do not get in each
other's way — a warning that fires when nothing is wrong teaches people to
click past the ones that matter.

## What to do about it

Both skills can usually run in the same workspace, as long as the one that
rewrites is not pointed at the same people. The page's last line says how.
Otherwise, keep the one already there, or let the new one take over the pages
and accept that what the old one added goes with it.
