How to Build an AI Research Loop That Cites Real Sources

An AI research loop is a workflow that runs live research before you build, sell, or publish: it splits your question into sub-queries, fans out across recent sources, cross-checks every claim against two or more of them, flags anything it could only verify in one place, and hands you a single brief with the links attached. Instead of one confident answer you cannot check, you get a cited brief you can.

That matters because the model's training data is stale by the time you read it. Ask a raw chatbot "what's working on YouTube right now" and it will answer with conviction from whatever it absorbed months or years ago. The loop fixes the stale-data problem by going and looking, then refusing to pass off a claim it could not corroborate. Here's the prompt, the shape of the loop, and the honest line between the no-code version and the engineer-grade one.

What is an AI research loop, and why not just ask the chatbot?

A research loop is the difference between a model guessing from memory and a model going to check. A one-shot prompt returns whatever the weights remember, dressed up as fact. A loop sends out fresh queries, reads what comes back, and keeps going until each claim is either backed by multiple sources or marked unverified.

This is one specific job built on a more general primitive. If you want the full picture of why authored loops beat hand-typed prompts, read the hub on what agentic loops are, which defines the goal-act-observe-decide-repeat cycle. This article assumes you know that shape and puts it to work on one task: research you can trust.

An AI research loop is an authored cycle that turns one question into many sub-queries, gathers recent sources, verifies each claim against two or more of them, flags single-source claims as unverified, and synthesizes one cited brief, repeating until every claim is resolved.

The credit here runs straight. Peter Steinberger (@steipete) put the posture into words: you shouldn't be prompting your agents anymore, you should be designing loops that prompt them. Boris Cherny, who leads Claude Code at Anthropic, ships the same pattern in real tooling: Claude Code has a /loop command that re-runs a prompt on a recurring interval with fresh context each pass, and a /goal command that keeps an agent working until a completion condition is met. Academically it descends from the ReAct paper (Yao et al., 2022), which interleaved reason, act, and observe in a cycle. The research loop is that cycle pointed at fact-finding.

What does the loop shape actually look like?

It looks like a cycle that refuses to stop while any claim is still unconfirmed. The stop condition is not "ran out of tokens" or "found something." It's "every claim is either corroborated by two-plus sources or explicitly flagged as unverified."

Walk one pass:

1. Decompose. Take the question and break it into sub-queries. "What's working in short-form video right now" becomes hooks, length, posting cadence, format trends, and so on.
2. Fan out. Search each sub-query across recent sources: Reddit, X, YouTube, Hacker News, the open web. Recent is the operative word. You're hunting for the last few weeks, not the all-time canon.
3. Cluster. Group what comes back by recency and by engagement, so a hot take with three upvotes does not get the same weight as a pattern showing up across a dozen threads.
4. Cross-check. For each claim, look for it in at least two independent sources. One source is a rumor. Two or more is a signal.
5. Flag. Anything the loop could verify in only one place gets stamped UNVERIFIED. It does not get quietly dropped and it does not get promoted to fact.
6. Decide. If claims remain unresolved, loop again with tighter queries. If everything is corroborated or flagged, stop.
7. Synthesize. Write one brief: the findings, the confidence level on each, and the source links.

The flagging step is the whole point. A model that says "I'm not sure, I only saw this once" is worth ten that sound certain about everything. You're engineering the loop to admit what it does not know.

What's the prompt that runs a research loop in a chat tool?

Here it is. Paste this into a chat tool that has a deep-research or web-browsing mode turned on (the no-code path). The prompt forces the fan-out, the cross-check, and the flagging in a single pass you can re-run.

You are a research loop. Your job is to return one cited brief, not a
confident guess. Today is [DATE]. My question is:

[YOUR QUESTION, e.g. "What hook styles are working for B2B short-form
video in the last 30 days?"]

Run these steps and show your work:

1. SUB-QUERIES: Break my question into 5 to 8 specific sub-queries.
   List them before you search.

2. FAN OUT: Search recent sources for each sub-query. Prioritize the
   last 30 days. Pull from a mix: forums, social, video, news, and the
   open web. Note the publish date next to each source.

3. CLUSTER: Group findings by recency and by how much engagement or
   repetition each one has. Separate "showing up everywhere" from
   "one person said this once."

4. CROSS-CHECK: For every claim you want to include, confirm it appears
   in at least 2 independent sources. List the sources for each claim.

5. FLAG: Any claim you can only find in ONE place, label it
   [UNVERIFIED - single source] and keep it in a separate section.
   Do not promote it to a confirmed finding.

6. LOOP: If any important sub-query came back thin or unresolved, run
   tighter searches and repeat steps 2 to 5 before you write the brief.

7. BRIEF: Write one synthesis, max 400 words, structured as:
   - Confirmed findings (with 2+ source links each)
   - Unverified / single-source claims (clearly separated)
   - What you could NOT find, and what I'd need to check manually

Rules: no claim without a link. If you are inferring rather than
citing, say so. End with a one-line confidence rating, 1 to 10, on the
brief as a whole.

Two things make this work. The [UNVERIFIED] rule gives the model permission to be honest instead of fluent. The "what you could NOT find" section surfaces the gaps a single confident answer would have papered over. Run it, read the confidence rating, and if it's low, tighten your question and run it again. That re-run is the loop.

If you want this prompt to become a button you press instead of text you paste, that's the move covered in turning AI prompts into reusable skills. Research is one of the highest-value jobs to package, because you run it constantly.

What's the real-world version of this pattern?

The clearest example is Matt Van Horn's open-source "Last 30 Days" skill. Van Horn (@mvanhorn, printingpress.dev) is the popularizer who packaged the loops idea for a wider audience, and "Last 30 Days" is a Claude Code skill that researches a topic across recent sources (Reddit, X, YouTube, Hacker News, the web) and synthesizes a grounded summary. It is the prompt above, hardened into a tool that hits more sources, more consistently, and can run on a schedule instead of when you remember to ask.

Van Horn's posture is "skillify everything": any job you repeat, turn into a reusable skill. Research is the textbook case. You don't want to re-paste a 40-line prompt every Monday. You want a skill that wakes up, runs the loop, and drops a cited brief in your lap. He builds adjacent tools too: "Printing Press" turns one prompt into an agent-native CLI for any API or site, and "Agent Cookie" keeps a headless agent logged in (more on that, and its risk, below).

The takeaway is not "go install his skill." It's that the no-code prompt and the engineer-grade skill are the same pattern at two altitudes. Start with the prompt. Graduate to the skill when you're running the loop often enough that the manual version is the bottleneck.

What's the honest difference between the no-code path and the engineer path?

The no-code path is a deep-research mode in a chat tool. The engineer path is a CLI skill that runs on a schedule. Both run the same loop. They differ in reach and effort.

The no-code path: use a chat tool with deep research or web browsing on, paste the prompt above, and explicitly tell it to list sources and flag single-source claims. You get most of the value with zero setup. The limit is that you're driving it by hand, and the model only checks the sources its search surfaces in that session.

The engineer-grade path: a CLI agent like "Last 30 Days" hits more sources, applies the same cross-check logic every time, and can run on a cron schedule so the brief is waiting before you ask. This path assumes you're comfortable in a terminal and with file paths. If running a job on a timer is where you want to go, how to run AI agents on a schedule covers the cron side. The mental model is a cron plus a decision-maker: the schedule decides when, the model decides what to do next.

Now the part nobody likes to say out loud. The loop reduces fabrication risk. It does not eliminate it. A human still reads the brief before it informs a decision. Cross-checking two sources is a real guardrail, but two sources can both be wrong, both quote the same original, or both be SEO spam. The confidence rating and the source links exist so you can sanity-check fast, not so you can skip checking. Any time a brief is about to drive a real move (a campaign, a budget, a public claim), you stay on the commit step.

This loop pairs naturally with using AI for SEO and AEO, where current, cited research feeds the content, and with the broader playbook in marketing with AI.

What about the "always-logged-in agent" trick, and is it safe?

Van Horn's "Agent Cookie" syncs live browser cookies and auth tokens to a second always-on machine so a headless agent stays logged in to the sites it needs to research. It's clever and it solves a real problem: agents get logged out, and a logged-out agent can't read gated sources. Gate this one hard.

Here's the plain risk. That pattern replicates live authenticated sessions to a second machine that an autonomous agent drives with no human watching. If that machine is compromised, or the agent gets prompt-injected by something it reads, the attacker inherits sessions that are already logged in to everything you're logged in to. No credential-theft step required. The encryption protects the transfer between machines. It does not protect the standing, unattended access sitting on the far end. Real convenience, real blast radius. For most operators, the no-code research loop covers the need without ever replicating your auth anywhere.

Frequently Asked Questions

Does an AI research loop guarantee the facts are true?

No. The loop lowers fabrication risk by cross-checking each claim against two or more sources and flagging anything it found in only one place. But two sources can both be wrong or both trace back to the same origin. Treat the cited brief as a fast-to-verify starting point, and keep a human reading it before it drives any real decision.

Do I need to code to build a research loop?

No. The no-code path is a deep-research or web-browsing mode in a chat tool: paste the prompt in this article and tell it to list sources and flag single-source claims. The coding path (a CLI skill that runs on a schedule and hits more sources) gives you more reach, but the chat-tool version delivers most of the value with zero setup.

Why not just trust the chatbot's first answer?

Because that answer comes from training data that's already stale, presented with the same confidence as a fact. A research loop sends live queries, reads recent sources, and refuses to state a claim it could not corroborate. The difference shows up most on anything time-sensitive: trends, prices, what's working right now.

How is a research loop different from a regular agentic loop?

A research loop is one specific application of the general agentic-loop pattern. The general loop is goal, act, observe, decide, repeat, explained in the agentic loops hub. The research loop points that cycle at fact-finding, with a hard stop condition: keep going until every claim is corroborated or flagged.

How often should I run it?

As often as the topic moves. For fast-changing areas like short-form video trends or competitor moves, a weekly run on a schedule keeps your briefs current. For slower topics, run it on demand before a specific build or campaign decision. The point is to research live, close to when the answer will inform an action.

Where should you take this next?

Start with the prompt above this week. Pick one decision you're about to make on stale assumptions, run the loop, and read the cited brief instead of guessing. Then decide whether you run it often enough to be worth packaging into a skill.
