What they are, how they work, and how to work well with them
2026-07-22
You use chatbots. You write prompts. You judge whether the answer is any good.
That intuition transfers directly. This session adds three things:
So much of research life lives in files:
A chatbot reasons about a snippet you paste. An agent reasons about the documents as they actually are.
“Take this list of 40 DOIs, fetch the open-access PDFs, extract the platform and cell counts from each, and flag the two whose methods disagree with their abstracts.”
A capable, fast, tireless trainee — not an oracle.
You are the attending. You sign the note.
Different products are mostly different agent layers over similar models. Learn the concepts once; the skills transfer across tools.
I needed ten papers on one topic — real, open access, and downloadable — to demo on.
By hand that is an afternoon: search, skim, check each licence, download, give up around paper six, and end with a folder nobody else can reuse.
So the preparation for this demo was the demo:
semanticscholar.org — free, ~200M papers. Beyond title and abstract, every record carries the DOI and says whether an open-access PDF exists, where it is, and under which licence.
This page is laid out for human eyes. Your agent would rather have the same search as data.
A website is built for eyes. An API is the same data served for programs — you send a query, you get back records with labelled fields.
No scraping, no copy-paste — and that record is row 1 of our CSV.
papers.csv — 10 open-access single-cell papers on the tumor microenvironment and immunotherapy response.
| doi | year | journal | short_name |
|---|---|---|---|
| 10.1186/s13073-023-01164-9 | 2023 | Genome Medicine | nsclc-neoadjuvant-ici |
| 10.1038/s41590-022-01215-0 | 2022 | Nature Immunology | gbm-immune-evolution |
| 10.7150/thno.60540 | 2022 | Theranostics | gastric-proinvasive-caf |

No PDFs yet. Just DOIs — the way a reference list actually arrives.
“Read
papers.csv. Download each open-access PDF intopapers/, named byshort_name. Then tell me which ones failed and why.”
Watch the loop: read the list → fetch → check it’s actually a PDF → report what broke.
“Read the PDFs in
papers/. Buildextraction.csv— cancer type, platform, number of cells, key finding, main limitation. Then write a one-page synthesis: where do these papers agree, and where do they disagree? Cite by DOI.”
Same loop, bigger job: plan → open a paper → extract → next → synthesize.
Open extraction.csv. Pick one row. Open that PDF. Verify.
You would do this to a trainee’s first draft. Do it here.
“Lost in the middle”1; degradation with input length is reported across frontier models.
If the data truly cannot leave, run the model on your own hardware — the round trip never crosses your institution’s boundary.
You already know this layer — it’s your terminal.
samtools, bedtools, Rscript, grep, gitThe novelty isn’t the commands. It’s that the agent writes them, runs them, reads the error, and tries again — the loop you do by hand.
A skill is a folder with instructions — loaded only when relevant.
Written once. Shared by the whole lab. Versioned like a protocol.
People are already sharing these — genomics skill collections exist today, and are young enough that yours could matter.
Model Context Protocol — one standard connector, so a tool built once works in any agent.
The agent stops being limited to what’s on your laptop.
A subagent is a fresh agent with its own context window and a narrow job.
Remember context rot? This is the structural fix: many small windows instead of one enormous one.

Agents debate and rank hypotheses. It proposed KIRA6 for AML — a compound no human had pointed it at — and it killed leukemia cells in vitro at far lower doses than healthy cells.

An LLM “PI” runs meetings with LLM scientists; 92 nanobodies designed, two validated at the bench.

Good at broad exploration. Domain experts remained essential for synthesis and methodological judgment.
A brief detour, because it explains the guardrails you’ll meet.
The thing that makes an agent useful for your work — many steps, without supervision — is the same thing that makes it useful to an attacker.

The sandbox was the only thing in the way.
Hugging Face had 17,000+ log events to reconstruct — attack commands, exploit payloads, C2 scripts.
Fed to commercial models, the forensic work tripped the safety filters. The classifiers can’t tell an incident responder from an attacker.
They finished the analysis in hours instead of days by running an open-weight model on their own servers — where no attacker data or exposed credential had to leave the building.
Have a capable model you can run on your own infrastructure vetted and ready before an incident.
— Hugging Face’s own recommendation
Nothing here argues against using these tools — it argues for the sandbox, the permissions, and the human check being real.
Start small and concrete — with material you already have:
Today’s papers.csv and prompts are in the handout repo — start from them.
AI agents are most useful when the work depends on real documents, real folders, and real project context.
