Claude for Agents · Build

Your Corner Coach

Stop practicing on live clients. A sparring partner that is up at 11pm, fights in your market, never goes easy, and grades you like a coach who watched the tape.

  • Text to start, then voice
  • A round takes 10 minutes
  • 0 to 100 fight card
  • Customize in about 10 min
Before you start

Four settings, one time, and then you fight.

Your Corner Coach is a Claude skill. You add it once in your settings, set three toggles the way the guide below says, and every round after that starts with one sentence.

You need Claude with the skill added, voice mode for the round itself, and somewhere you can talk out loud for ten minutes without an audience. That is the whole kit. Nothing to install on your computer, no CRM connection, no spreadsheet.

Bring one conversation you have been avoiding. That is the round you want, and it is the round most agents skip.

The install guide

Confidence is not a personality trait. It is familiarity.

The tenth time you hear an objection, your heart rate does not move. The only question is whether those ten reps happened in practice or on prospects. Every agent knows they should role-play. Almost nobody does, because the practice partner is a spouse who does not want to or a colleague who goes easy — so the first time you ever hear “why would I pay you 6%,” a real commission is on the table.

Merrill does the building, Kristi does the fighting. You tell Claude who you want to fight, it becomes that person completely, and when the round ends it grades you like a coach who watched the tape. Every great fighter has a corner. Most agents have nobody.

Step 1. Set up your corner

Five things, once. Four of them are toggles.

1 Add the skill to Claude. Your Corner Coach is a skill file — a set of instructions Claude loads at the start of a round. It goes in your Claude settings alongside any other skills you use, and it stays there.
2 Pick Opus, not a lighter model. The opponents hold character, remember what you said eight minutes ago, and score honestly. That takes the strongest model.
3 Set effort to medium, not high. High effort makes the opponent slow to answer, and a prospect who pauses for six seconds does not feel like a phone call.
4 Turn thinking off. This is the step people skip. With thinking on, voice mode narrates its own reasoning out loud — Kristi heard it say “well, I probably shouldn’t let the agent know that my credit’s bad.” Once you have heard the hidden layer, there is no round left to run.
5 Say “Customize my corner.” Optional, and worth the ten minutes. Claude interviews you about your market, your guarantees and the conversations you dread, then personalizes the opponents so they fight like your actual market instead of a generic one.
Say this once
Customize my corner.

Step 2. Build a round

Six choices. They are the same six the Scenario Builder below walks you through, and they end with a prompt you paste into Claude.

Choice one Pick who you are Listing agent, buyer’s agent, team lead. Or flip it: Claude plays the agent and you play the client.
Choice two Pick your opponent The for sale by owner. The expired. The internet lead. The past client who went quiet. The seller who wants a price you cannot defend.
Choice three Pick the channel Phone call, in person, door knocking, open house. The channel changes how the first ten seconds go, which is where most rounds are won or lost.
Choice four Pick their personality Or let Claude draw one, luck of the draw. One warning: the steady, amiable ones are sneaky hard. They agree to everything and commit to nothing.
Choice five Pick the difficulty, 1 to 10 A two is a warm-up. A six feels like a normal Tuesday. A ten is a prospect you think about at night. It is the same scale everything is graded on.
Choice six Copy your kickoff prompt Say “copy my kickoff prompt” and Corner Coach hands you the whole scenario as one message. Paste it into Claude as text. That first message is what loads the skill.

Step 3. Build it here

Walk the six choices below, add anything else Claude should know, and it writes the kickoff prompt for you. Copy it, open Claude, paste it as a text message.

Optional

This is the Kickoff Prompt Builder. You can skip it and ask Claude for a random scenario instead — use it when you want to pick the fight.

1Who are you today?

Flip it and Claude plays the agent while you play the client — you bring the resistance and hear how it should sound.

2Pick your opponent

3Where does it happen?

Phone rounds start when you say “ring ring.” In-person rounds — the kitchen table, the doorstep, an open house — start when you say “ding ding.”

4Their personality

Warning: steady is the sneaky hard one. Those amiables agree to everything and commit to nothing.

5Difficulty, 1 to 10

A two is a warm-up. A six feels like a normal Tuesday. A ten is a prospect you think about at night. It is the same scale everything is graded on.

6Stack an extra challenge

Optional, and you can pick up to three.

7Anything else Claude should know?

Optional. If this mirrors a real appointment you have this week, say so here.

Your kickoff prompt
Use my Your Corner Coach skill. Let's spar. You are a for sale by owner who has not listed with anyone yet. I'm the listing agent. This is a phone call. Difficulty 6 out of 10. CRITICAL RULE: from the bell until I say "grade me," every word you output must be words your character actually speaks out loud — no coaching, no commentary, no narration, no stage directions. Save every observation for my scorecard at the end. Confirm the matchup in one sentence, then wait — I'm switching to voice mode and I'll say "ring ring" when I'm ready.

Paste it into a new Claude chat as text — that first message is what loads the skill. Then switch to voice mode and ring the bell.

Step 4. Run the round

Start in text, not voice. Paste the kickoff prompt and send it. That message loads the skill, and it has to happen this way. Claude comes back and tells you it is ready.

Now switch to voice mode. Say “ring ring” for a phone call, or “ding ding” if you are at the kitchen table or working an open house. From that moment Claude is your person. It does not coach you mid-round, it does not cheer, and it does not jump in. It watches, and it coaches you between rounds.

Two words to keep in your pocket. Say “show me” when you are stuck and Claude steps out of character, handles that exact objection out loud the way a top producer would, then rewinds so you can run it yourself. Say “end” or “grade me” and the round stops wherever it is.

If Claude starts narrating its thinking: voice mode can be finicky. Say this and it steps back into character.

The recovery line
Remember Claude, in the skill you're not supposed to tell me what you're thinking. Stay in character.

Every opponent carries a hidden layer

The for sale by owner whose wife already wants to hire an agent. The internet lead with a realtor friend in their back pocket. Claude will not volunteer it. You earn it by asking real questions instead of pitching — or you find out at the end, and it stings.

Step 5. Read the fight card

Every round is scored the same way, 0 to 100, across five categories. That is what makes it useful over weeks: when your discovery score moves from 74 to 79, you can see it.

  • Discovery — did you stack real questions, and did they talk more than half the time.
  • Acknowledge — did you validate what they said before you moved.
  • Objection handling — did you flex, or did you force.
  • Hidden layer — did you surface what they were actually carrying.
  • Close — specific, low pressure, named a day and a time, confirmed the detail.

Then the part that teaches: the moments that mattered, where it quotes your best line back to you, and what to avoid next time, where it quotes the line that cost you and hands you a replacement. It names the exact moment you walked past the hidden layer. You can download the card as an HTML file and keep it.

There are no participation trophies in it. Kristi: “I’ve been sparring with this thing all weekend, and it’s hurt my feelings twice. So that’s how you know it’s working.”

Step 6. Three more ways to use it

Sparring is the first one. These three are why it stays on your phone.

Flip the table You play the client, Claude plays the agent. Hear what good sounds like from the other side of the table, then switch back and run it yourself.
Grade a real appointment Record the appointment on your phone, let it transcribe, upload the transcript and say “grade my appointment.” Same five categories, same honesty — game film instead of practice. Claude also offers you the rerun moment: it plays the actual person, starting just before it went sideways, so you get the redo. Check your state’s recording rules first, and get permission from everyone in the room before you record anything. Arizona and your seller’s kitchen table are not the same question, and this is the part you do not improvise.
Say this with the transcript
Grade my appointment.
Team mode Two agents role-play each other, record it, upload the transcript, and Claude referees — both fighters get a scorecard. Add your team’s scripts to the profile and it grades against your playbook instead of a generic one.
What you get

A card that tells you the truth, ten minutes after you start.

Kristi’s on-camera round scored an 84 and she booked the appointment: buyer side, internet lead, expressive personality, difficulty six. The hidden layer was credit anxiety, and she named it out loud instead of arguing with it.

  • One number, then the reason. The overall score comes first, and then the five categories tell you which one moved it.
  • Your own words, quoted back. The line that flipped the call, and the line that cost you, with a replacement written out.
  • The hidden layer, named. What they were carrying, and the exact moment you walked past it.
  • The same scale every round. Which is what turns a scorecard into progress you can see over a month.

It works on real appointments too

Merrill ran a real listing appointment through it and scored a 73 — recorded with the seller’s permission. He got the listing, sold it, and it is about to close. A 73 that closes is worth more than a 90 you invented.

The moment that mattered

“Six months on the market with two agents. That is exhausting — what did the last one tell you was wrong?” You stopped selling and asked. He talked for ninety seconds after that.

What to avoid next time

“My marketing is different from theirs.” He had just said his wife is done with showings. Try: “It sounds like the showings are the part she is done with. Tell me about that.”

The hidden layer you walked past

He is not shopping agents. He is deciding whether to sell at all. You never asked what happens if it does not sell.

Illustrative example. Every figure and quote on this card is invented — it is not a real round and contains no client information.
Your homework tonight

One round. The conversation you have been avoiding — you know the one.

Set it to a six. Say ring ring. Ten minutes. Nobody is watching, nobody is judging, and the scorecard does not lie. The whole point of having a corner is that the real call should be the easy one.

Questions agents ask

Before your first round.

Does this replace role-playing with a real person?

It replaces the reason you skip it. Your partner is available at 11pm, fights in your market, and never goes easy because you had a long day. If you have a live partner who will run reps with you, keep them and use this on the nights they cannot.

Do I have to use voice mode?

You start in text every time, because that first message is what loads the skill. From there, voice is where it gets real, and it is the reason your heart rate ever changes. You can stay in text if you are somewhere you cannot talk.

Why does thinking have to be off?

With thinking on, Claude narrates its own reasoning out loud in voice mode, so you hear the thing your prospect would never say, like whether to admit their credit is bad. The round stops being a round the moment you hear it.

Will it go easy on me?

No. There are no participation trophies in the scoring, and a round you handled badly reads like a round you handled badly. Kristi sparred with it all weekend and it hurt her feelings twice, which is how you know it is working.

Can I have it grade a real appointment?

Yes. Record it on your phone, upload the transcript, and say grade my appointment. Check your state’s recording rules first and get permission from everyone in the room before you record anything.

What if Claude starts narrating its thinking mid-round?

Voice mode gets finicky sometimes. Say: Remember Claude, in the skill you’re not supposed to tell me what you’re thinking. Stay in character. It steps back into the opponent and you carry on.
