Pirxey World: our second brain, with the access we already had.

We built our second brain around the access people already had, adding separate GitHub repositories for shared, strategic and private knowledge and skills. Permissions were already complicated enough. CRM kept its existing access rules. Google Drive stayed shared with the same people. Role-specific tools stayed with their users. We could start without rebuilding all of that.

See who can access what
The tools we already use

Same person. Same access.

Choose an example person. Their assistant works through their accounts; it does not get a new company-wide identity.

This person has CRM and Drive access. Their assistant uses those same accounts.

Illustrative profiles, not a live access audit. Bank is an example, not a confirmed integration. Connections show account use, not passwords sent to the model.

GitHub · knowledge and skills

What we did need to divide.

We needed somewhere to keep what we learned, including skills: written procedures an assistant can run. A repository is a shared home for those files, with its own access list.

Company knowledgeShared with everyone

Department A

Standard knowledge + skills

Procedures, working notes, a reporting skill.

Readers: people with access to this department repository.

Strategic knowledge + skills

Strategy, management decisions, confidential material.

Readers: owners and directors granted access to this repository.

Department B

Standard knowledge + skills

The same structure, with this department’s own access list.

Strategic knowledge + skills

A separate repository with a shorter reader list.

My private repository

Personal notes + skills → only me.

Being someone’s director does not give their assistant access to that person’s private notes.

A colleague improves a shared skill → saves it in the department repository → colleagues with access receive it after sync. Each runs it using their own logins, without inheriting the author’s permissions. Credentials stay out of shared knowledge.

Illustrative structure, based on the owner’s description; not a live access audit. The rule is two repositories per department, plus one private repository per person. Our September 2026 inventory had strategic repositories in 6 of 15 departments. Job titles alone do not grant access.

Where things live. The assistant runs on the laptop, the knowledge arrives from the repositories above, and the only thing that leaves is the text sent to the model provider.

Before AI

The old part of the problem.

Who should have access, and who no longer should, was a problem long before AI. An assistant inherits it.

Four plain questions

Is this safe?

Is it safe? It uses your own logins, nothing more.

Does my data go to external servers? Only the question and the text the assistant picks go to the model provider. The rest stays on your laptop.

Do I keep my access? Yes. Nobody gets access through the assistant that they did not have before, and removing someone’s access in a tool removes it for their assistant too.

Do I need to anonymise? Decide what can go to the model before you send it. Reading is not permission to redistribute: an answer may reach someone who could not read its sources, so shared knowledge is checked before it is saved. How we decide what may go there.

For how the assistant finds the right knowledge, see how it reads the index first.

Mission control standing by

Enough to get started.

We could develop shared knowledge and skills without waiting for a permission system of our own. That was enough to start. Keeping access current is still our job.
