A conversation is always one Agent + one Project. The Agents you can pick depend on the Project's type.

Change Assessment

I can help you assess this analytical-method change end to end. Tell me what's changing and I'll trace the impact across the Brain, flag the risks, and build the change task list with you.

What's the change you're proposing for Aspirin?

You
We're replacing the current HPLC method for related substances — moving to a shorter C18 column and tightening the salicylic acid limit from 0.15% to 0.10%.
Change Assessment

Got it — a method change plus a spec tightening. Let me look across what the Brain holds for Aspirin and trace where this lands.

Here's the impact I can see so far:

🔬
Analytical Methods — the current related-substances method is on file and referenced by 3 controlled documents. Verified
⚗️
Impurity Data — salicylic acid historically runs 0.04–0.08%, so a 0.10% limit is achievable on current data. Verified
📈
Stability — a tighter limit may interact with end-of-shelf-life results, but the Brain has no local stability dataset for this method; this rests on external literature. Provisional

The first two are grounded in Aspirin's own records. The stability point is an assumption I've drawn from public sources — worth confirming before it goes in the task list. Want me to draft the task list now?

You
Yes, draft the task list.
Change Assessment

Here's a first draft. Each task carries where it came from, so a reviewer can see the basis.

◈ Change task list — Aspirin RS methodDraft
1
Revise the related-substances test method
Owner: QCVerified
2
Update the finished-product specification (SA limit 0.10%)
Owner: QAVerified
3
Method validation / transfer for the new column
Owner: ADVerified
4
Confirm stability impact of the tighter limit
Owner: StabilityProvisional

Task 4 is flagged provisional — it exists because of the assumption, not a verified finding. When you're happy, use Write back → to propose this to the Brain.

🔒 Supplementary data you add is used for this run only — it enters the Brain only through the double gate.

Both consents were given. The task list and conversation entered the Aspirin Brain as a new source in Analytical Methods — provenance-stamped and comprehended like any other source.

General chat

This is the open way in — an ordinary conversation with the Aspirin Brain, for anything a purpose-built agent doesn't cover. I draw on the same knowledge and flag verified versus provisional the same way.

Ask me anything about this product.

You
What's the historical range for salicylic acid at release?
General chat

Across the last 24 release batches it runs 0.04–0.08%, comfortably under the current 0.15% limit. Verified

Brain · pattern watch
Recurring question detected
"Impurity history & limit headroom"
The same question shape has been asked 7 times this quarter by 4 people across 3 products, and each time it resolves the same way — pull the release history, compare against the registered limit, state the headroom. That is a repeatable task, which is what a purpose-built agent is for.

If we tightened the release limit to 0.10%, would that affect end-of-shelf-life results?
General chat

Probably not at release, but I can't answer the shelf-life half from your own records. Aspirin hydrolyses to salicylic acid over time, and published stability work suggests end-of-life values typically sit 0.03–0.05% above release. Provisional

Assumption in use Provisional
End-of-shelf-life salicylic acid rises 0.03–0.05% above the release value under the registered storage condition.
🌐
External literature — gap-filled. The Aspirin Brain holds no stability dataset for this method, so this is inference, not your data. It cannot be promoted on its own.
0 findings selected for write-back — both gates still apply before anything enters the Brain.
💬 Open mode — bound to the project, not to a single goal. Still honours verified-vs-provisional.
