Every senior professional eventually asks the same question, usually around the third or fourth working session with Claude. What is this thing actually allowed to do for me?
The honest answer is that the model itself is not the limit. The limit is judgment, confidentiality, and the responsibility that comes with your name on the work. Once you draw that line clearly, the rest of the workflow gets simple.
We call it the Fiduciary Firewall.
The line in one sentence.
AI handles first-pass synthesis. The professional handles judgment, signature, and the relationship.
That is the whole rule. Everything else is detail.
What sits on each side
Things AI is good for, every time:
- First-pass synthesis of messy material
- Organizing notes, data, and references
- Identifying gaps and missing details
- Drafting structure for memos, recaps, and follow-ups
- Rewriting your own prose for tone or length
Things that stay with the human, always:
- Judgment, what to do, what to recommend, what to ignore
- Final signature on anything client-facing
- Recommendations and advice
- The client or partner relationship
- Ethics, confidentiality, and the regulated parts of your work
Sanitization first, always.
Before any of that matters, you sanitize the input. Use placeholders: [Client A], [Matter X], [8-figure revenue]. Strip names. Strip specifics. Strip anything you would not want repeated in a coffee line.
This is not paranoia. It is the same instinct you already apply when you complain about a client to a colleague at a conference, you describe the shape of the problem without naming the parties. The Fiduciary Firewall is that instinct, in writing.
The printable Fiduciary Firewall.
Members get a one-page, printable version of the Firewall, a quadrant diagram, the sanitization rules, and three real (anonymized) examples for legal, finance, and advisory work. Tape it up. Hand it to a junior.
The hardest part is not the rule
The hardest part is the discipline. Most senior professionals know the rule after about thirty seconds of explanation. The discipline takes a quarter.
The Firewall holds when there is no time, when the deadline is tight, and when the temptation to paste the easy version of the real document is at its highest. That is where the senior judgment shows up, not when it is convenient.
