Prompting Gemini well

Three skills, plus the Gemini-specific moves

12 min read·3 of 4 in the Claude track

The three core skills — prompt anatomy, the iteration loop, magic phrases — are the same across all chat AIs. If you've read the Claude or ChatGPT Skills pieces, you already know most of this.

Where Gemini differs is in the moves that take advantage of its strengths: live search, long context, and Google Workspace integration. This page covers the core skills quickly, then spends real time on those Gemini-specific levers.

If you haven't covered the core skills in detail, the Claude Skills piece is the longest treatment. This page assumes the basics and goes specific.

PART 01

The three core skills (the short version)

1. Prompt anatomy: context + goal + constraints + example

Tell Gemini who you are, what you want, what would make a bad answer, and (when helpful) what good looks like. Specificity beats length.

2. The iteration loop

First response is a starting point. Read it. Give surgical feedback. Repeat. Vague feedback gets vague improvements.

3. Magic phrases that consistently work

"Explain your reasoning."
"What could go wrong with this?"
"What are the tradeoffs?"
"Is there a simpler way?"
"Push back on this."
"Give me three versions."
"Explain it like I'm new to this."

These work across Gemini, Claude, and ChatGPT. Same reasons, same effects.

PART 02

Gemini-specific: using live search well

Gemini grounds answers in Google Search by default. This is the single biggest functional advantage over Claude and ChatGPT — and most people use it badly.

Three habits make search-grounded prompting actually work.

Habit 1 — Ask for sources explicitly

Gemini will cite sources sometimes and skip them other times. If sources matter, ask for them. 'Show me the sources for each major claim.' 'Cite the URL for any specific fact.' This locks in the verification path before you read the answer.

Habit 2 — Ask for date-bounded answers

When the question is time-sensitive, say so. 'In the last 30 days,' 'as of this month,' 'since [event].' Without this, Gemini might mix old and new sources without telling you. With it, you get answers that match the time window you care about.

Habit 3 — Verify before acting on specifics

Click the citations. Read the source. Especially when the answer is about something that matters — money, health, legal, important decisions. Citations are a starting point for verification, not a substitute for it.

PART 03

Gemini-specific: working with long documents

Gemini's context window is the largest of the three by a wide margin. You can upload long documents — books, papers, transcripts, reports — and ask questions across all of it at once.

Two tricks make this work.

Trick 1 — Ask for the document's structure first

Before drilling into details, ask Gemini to map the document. 'Give me a section-by-section outline.' 'What are the three or four key arguments?' 'Where in the document does X come up?' This grounds the rest of the conversation in real geography.

Trick 2 — Anchor your questions to locations

Instead of 'what does this say about X,' try 'on page 42, where the author argues Y, is the claim supported by the evidence in section 3?' Gemini does better when you tell it where to look.

The combination of search-grounding and long-context makes Gemini uniquely strong for research. Upload a paper, ask for a structural summary, then ask Gemini to find what's currently happening in the field (using search) that the paper missed.

PART 04

Gemini-specific: living inside Workspace

Gemini is in the sidebar of Gmail, Docs, Drive, Sheets, Calendar. This is convenience-level integration — the kind that doesn't change what's possible, but changes what's effortless.

Use it for everyday tax: summarize this email thread, draft a reply, find what I committed to in this doc, schedule something, pull data out of a sheet. Each one of these is a 30-second task that used to be a 5-minute task.

Don't use it for serious thinking or writing. The sidebar is optimized for quick. For depth, open the full Gemini chat.

TAKEAWAY

The order to do this in

If you're going to invest one hour in getting better at Gemini, here's the order:

1. Get the three core skills locked from the Claude or ChatGPT Skills piece. Same skills, all tools.

2. Practice asking for sources and date-bounding on search-grounded questions. Click the citations.

3. Try a long-document task: upload something substantial and work with it.

4. If you live in Workspace, turn on the Gemini sidebar and use it for one week. Notice what changes.

Try it now

Three exercises matched to Gemini's specific strengths.

Practice 1 — A grounded current-events question

Answer this question using current sources.

Question: What are the most significant developments in the last 30 days in [TOPIC YOU FOLLOW]?

For each, cite the URL. Quote the specific sentence that supports each claim. If you can't find a direct supporting sentence, say so — don't paraphrase.

Practice 2 — A long-document analysis

(Upload a long document — a paper, a report, a long article.)

I want you to do three things:

1. Give me a section-by-section outline (one sentence per section).
2. Identify the three most important specific claims, with the location in the document where each appears.
3. Tell me what's missing — what would I want to know that the document doesn't cover.

Then we'll drill in.

Practice 3 — Workspace sidebar

(This is an exercise — only works if you use Google Workspace.)

Open Gmail. Find an email thread you've been putting off responding to. Open the Gemini sidebar. Ask:

"Summarize this thread. What's the actual ask? Draft a short reply that addresses the ask directly, in my voice."

Notice the speed compared to dealing with it manually.
