Claude for Agents · Build

Quick Comps

Say “prep me for the Johnsons” and get a branded briefing back — segment health, negotiation room, a card per home.

  • Phone-friendly after setup
  • Setup ~15 min
  • Google Drive
  • On demand

This guide has been updated since the video — the steps are the same, the screens look a little different.

Before you start

One desktop step, then it lives on your phone.

The skill upload needs a laptop or desktop browser once. After that, every output works from your phone — the doc you read in the car between showings is the doc this skill produces.

You need Claude Pro or higher with code execution and file creation switched on, the Google Drive connector, and an MLS account you can build saved searches and exports from.

You don’t need Claude Desktop or Cowork. Quick Comps runs on demand, not on a schedule — claude.ai in any browser, or the mobile app, is all it wants.

Get the files

The install guide

Statistical prep for every hot client, from your phone.

Three outputs, one client file. Ask for what you need and the same data answers a different question each time.

Step 1. Pre-flight checklist

About the “allow network egress” toggle you'll see under code execution: you don't need it. The skill works entirely from the data in your Sheet and never makes outbound web calls. Leave it off — that's the safer setting and Quick Comps doesn't notice the difference.

Step 2. Install the skill

The skill knows how to read your comp data, anchor on a defensible value, measure leverage and produce the memo the same way every time — so the number is reproducible.

  1. Get the skill file from the email above and save it somewhere you can find again.
  2. On a desktop or laptop browser, open Customize → Skills in claude.ai.
  3. Click +, choose to create or upload a skill, and select the file as-is. No need to unzip.
  4. Find it in the list and make sure the toggle is on.

Verify it. Start a new chat and ask what the quick comps skill does. If Claude describes the comps workflow, you're good. This upload is the only piece of the whole workflow that needs a computer — the mobile app can't upload skills.

Step 3. Tell it who you are

Your Brain Doc is what makes Quick Comps yours. The skill reads it on every run to know who you are, what market you're in, and how you build a comp set. Start with the identity that prints on every memo footer: name, brokerage, license number, phone, and the state you're licensed in.

Step 4. Your client files folder

Quick Comps works on a folder-of-clients pattern. You create one folder. Each hot buyer client gets their own MLS export inside it, scoped to their must-have criteria. When you ask Claude to prep you for the Johnsons, it finds the Johnson file automatically.

Why this beats a geographic comp library. A wide-geography, tight-criteria export — say single-level pool homes 1,800 to 2,800 sqft across two cities — is usually under a megabyte and carries far higher-signal data than “every home in one town”. Because the file is already filtered to the must-haves, Claude can run the analysis directly against it: no per-property comp pulling, no slow downloads.

Create the folder

  1. In your browser, open Google Drive.
  2. Create a new folder — Quick Comps Client Files is a clean default.
  3. Copy the folder's link. Claude extracts the folder ID from it automatically, and you'll paste that link into your Brain Doc in Step 6.

Build a good client export

The discipline is filters first, geography second. Your export should be wide enough geographically to cover their search area, but tight on the criteria they won't bend on. The criteria filters are what keep the file small.

  1. Set the hard filters first — single-level only? Pool required? Bedroom count? Price range? These are what shrink the result set.
  2. Then set the geography — the cities or ZIPs they'll consider. Going wide here is fine, because the filters above already control the size.
  3. Set the time window — the last six to twelve months, statuses active, closed, expired, cancelled and under contract.
  4. Drop the heavy text columns if your MLS lets you pick an export template: features, public remarks, private remarks. That's about 80% of the bytes and none of it is used.
  5. Paste it into a new Sheet in your folder and name it after the client. A tight, criteria-scoped export usually clears 500 KB.

Use your MLS's saved-search feature. Save the search with the client's name on it. To refresh their file later you re-run the saved search and paste over the existing Sheet — replace, don't append. Old comps drop off the back, new ones come in the front.

Name the files so retrieval is one-shot

Claude is good at fuzzy matching — “Mike Johnson” still finds the file when you say “the Johnsons” — but consistent naming makes it reliable. Good: Johnson Family, Mike Johnson — Chandler, Williams Spring Search. Avoid cryptic abbreviations only you understand; those make Claude ask “which file?” more often. When a client closes or pauses, drag their file into an Archive subfolder — the folder listing is your active-client roster.

Step 5. How you run comps

The data shows price, size, year and location. It can't see condition, layout or finish. So this step is where your judgment gets written down: read the starting methodology and change the lines that don't match how you actually build a comp set.

This is for typical deals. Bread-and-butter comps. Highly custom or one-of-a-kind properties always need a human read — that's not what this is for.

What disqualifies a property from being a comp

  • A different number of stories — never compare a two-storey to a single-level.
  • Septic against sewer.
  • A different lot type — acreage against a subdivision lot, rural against urban.
  • A significantly different bedroom count. A three-bed and a five-bed are not the same comp.
  • A different property type — single-family, patio home and townhome are three different things.

What you weight comps by, in order

  1. Square footage — closest size first.
  2. Year built — within five years if possible.
  3. Upgrade and finish level — builder grade against renovated against luxury.
  4. Pool: presence and quality.
  5. Lot size and premium features — view, corner, oversized, cul-de-sac.

What the data never sees

These become “confirm at the property” prompts in every read: condition, finish quality, floor-plan flow, kitchen layout, lot quality and orientation, smell and sound and the neighbor situation — and anything that would scare off a buyer in the first thirty seconds.

There's room for two more things: anything about your market the data hasn't caught up to yet, and any personal rule you want respected — “I never recommend going above list”, or “on rural acreage, widen the comp radius to five miles”.

Step 6. Wire it up

Your answers become a Brain Doc that lives in a project's custom instructions, so every chat in that project loads it automatically. Paste the block below with your own answers filled in.

Your Brain Doc
QUICK COMPS — BRAIN DOC

WHO I AM
- [first] [last] · [brokerage] · license [number]
- [phone] · licensed in [state]      (this prints on every memo footer)

WHERE MY CLIENT FILES LIVE
- Folder: [paste your Google Drive folder link]
- One Sheet per hot client, named after the client.
- Refresh a client's Sheet by re-running their saved MLS search and pasting
  over it. Replace, never append.

HARD FILTERS — that's not a comp
- Different number of stories.
- Septic vs sewer mismatch.
- Different lot type (acreage vs subdivision, rural vs urban).
- Significantly different bedroom count.
- Different property type (single-family vs patio home vs townhome).
- [your own]

WEIGHTED FACTORS, IN ORDER
1) Square footage, closest first.
2) Year built, within 5 years where possible.
3) Upgrade and finish level.
4) Pool: presence and quality.
5) Lot size and premium features.

CONFIRM AT THE PROPERTY — the data never sees these
Condition · finish quality · floor-plan flow · kitchen layout · lot quality and
orientation · smell, sound, neighbors · anything that loses a buyer in the
first 30 seconds.

MY RULES
- [e.g. I never recommend going above list.]
- [e.g. On rural acreage, widen the comp radius to 5 miles.]
- Market temperature is derived from my closed comps on every run — don't ask
  me to declare it.
  1. In claude.ai, go to Projects in the sidebar — the regular Projects section, not Cowork. Quick Comps runs on demand in normal chats.
  2. Click + New Project and name it Quick Comps.
  3. Paste the Brain Doc into the project's custom instructions field and save.
  4. Inside the project, confirm the skill is available and the Drive connector shows as connected.

Step 7. The first test — pick a hot client

The whole point is real client prep, so test it on a real one. Build their saved search in your MLS, export, paste into a new Sheet in your folder, name it after them — then start a chat inside your Quick Comps project and try all three modes.

  1. Segment report: “Prep me for the Johnsons this weekend.” No addresses needed — Claude finds the file by name and gives you a segment briefing with three talking points.
  2. Showing prep: “I'm showing the Johnsons these three homes Saturday…” and it builds a card per home, color-coded by pricing health, with watch-outs and walk-through prompts.
  3. Single property: “Run quick comps on [address] for the Johnsons.” The three-tier ladder memo, with pricing-health gating.
  4. Read the outputs on your phone — that's what they're designed for. Check the market-temperature stats against your gut. If anything feels off, tune the methodology in your Brain Doc and re-run; the skill picks up changes immediately.

Common first-run snags. “I don't see a file matching that client” — the file isn't created yet, or the name doesn't match cleanly; rename it or paste the Drive link directly to override. “That subject couldn't be resolved” — the address isn't in that client's file, usually because it falls outside the criteria you exported on. “The file is too large” — you've gone too wide on geography; tighten the filters, not the map.

Step 8. Keep the client files fresh

Quick Comps is only as smart as the data behind it. Refresh a client's Sheet whenever you're about to prep for them: re-run the saved search and paste over the existing data. Replace, don't append — old comps lose relevance fast, and the skill derives your market temperature from this data on every run.

Your folder is your roster

When a client closes or pauses, archive their Sheet. What's left in the folder is exactly who you're actively working — which is a useful thing to be reminded of on a Friday afternoon.

What you get

The doc you read in the car.

Showing prep for one client: the segment first, then a card per home with pricing health, comp value and what to confirm on the walk-through. Every address and figure here is invented.

  • The segment, before the houses. Sale-to-list, days on market and how often homes clear list — so you walk in knowing how much room there is.
  • Pricing health per home. Fresh, adjusted, untested or overpriced-by-time. It's the difference between a negotiation and a waiting game.
  • A comp value, not a guess. Anchored on the comps in that client's own file, with the spread against asking shown plainly.
  • Watch-outs named. The thing a buyer's agent will push on, and the thing that will scare your client in the first thirty seconds.
  • Walk-through prompts. What the data can never see — condition, flow, finish, neighbors — as questions to answer while you're standing there.
Sample — fictional data
Showing prep · Saturday

The Renner family — 3 homes, and one of them has real room

Single-level, pool, 3+ bed, $520–690K · 214 records in their file

98.1%
Sale to list, last 90 days

Median days on market
1 in 9
Closed above list
3418 Saguaro Vista Overpriced by time

Asking $649,000 · comp value $611,000 · 78 days, one $15K cut. Two comps within 60 sqft closed at $604K and $617K. There is room here, and the seller has now watched two months go by.

Watch-out: backs the collector road — check the patio noise. Confirm on the walk: original kitchen? The photos are three years old.

1207 Dry Creek Court Fresh

Asking $624,900 · comp value $626,000 · 6 days. Priced at the comps, so expect competition rather than negotiation. If they love it, move Saturday.

Confirm on the walk: cul-de-sac premium is real here — is the lot actually bigger, or just shaped oddly?

Third home summarized below in the full doc. Focus line: lead with Dry Creek, use Saguaro Vista to show them what waiting looks like.

Questions agents ask

Before your first prep.

Does it pull comps for me from the MLS?

No. You build the client's saved search and export it — that discipline is what keeps the file small and high-signal. The skill analyzes what you exported and never goes looking for sales on its own.

Do I need Claude Desktop for this one?

No. Quick Comps runs on demand in a normal chat, so claude.ai in a browser or the mobile app is enough. Only the one-time skill upload needs a computer.

What if a property my client wants to see isn't in their file?

Then it falls outside the criteria you exported on. Widen the filters in their saved search and refresh the Sheet, or analyze that property as a one-off — but don't quietly widen the client's must-haves to make the tool happy.

Can it recommend offering above list?

Only when the data supports it. The single-property mode is gated so a home that's been sitting and overpriced never gets a recommendation at or above list, and your own rules in the Brain Doc override the default either way.

This is the market read we teach you to do by hand. AI Marketing Academy scores your whole area on real buyer demand and drafts the outreach for you, if you would rather not run it yourself. Here is what you actually get inside it.
