Post: How to Write a Brief for Claude That Produces a Production-Ready Make Scenario
The Make MCP for Claude builds exactly what you describe. That’s not a selling point — it’s a warning. Give it a vague brief and you get a vague scenario. Give it a precise brief and you get a production-ready scenario, often on the first pass.
This lesson — description precision — is the single most important thing we’ve documented in our field report on using Claude for Make automation builds. The AI is not going to read your mind. It’s going to read your brief. So the brief is the work.
Below is the exact structure we use. Follow it and Claude stops guessing. Follow it and your scenarios stop coming back with broken modules, missing routes, and credentials you have to fill in manually.
Answer: What Makes a Good Brief?
A good brief gives Claude seven things: the trigger, the data shape, the routing logic, the error conditions, the output destination, the credential names, and any known edge cases. Cover all seven and Claude builds a complete, deployable scenario. Miss any one of them and you’re patching gaps after the fact.
Before You Start
Before you write the brief, do two things.
First, map the workflow on paper or in a whiteboard tool. Know what fires the scenario, what data it handles, and where that data ends up. If you can’t draw it in two minutes, you don’t know it well enough to brief it yet.
Second, pull your credential names from Make. Not the tool names — the actual connection names as they appear in your Make account. Claude will use exactly what you give it. “My HubSpot connection” is not a credential name. “HubSpot – 4Spot Production” is.
Once you have both, you’re ready to write.
Step 1: State the Trigger
The trigger is what fires the scenario. Be specific about the module type and the condition.
Weak: “When a form is submitted.”
Strong: “Trigger: Webhook – Custom webhook. Fires when a Typeform submission is received. The webhook URL will be configured in Typeform’s integration settings after the scenario is built.”
Include whether the trigger is a webhook, a scheduled poller, an instant trigger from a native module, or a manual run. If it’s a scheduled trigger, include the interval. If it’s a webhook, note whether the payload structure is known — and if it is, paste a sample payload directly into the brief.
Claude uses the trigger definition to set the first module and determine what data is available downstream. A weak trigger definition means Claude has to infer the data shape. That’s where errors start.
Step 2: Define the Data Shape
Tell Claude what data enters the scenario and what format it’s in. This is where most briefs fall apart.
If the trigger is a webhook, paste a real sample payload. If the trigger pulls from an API, describe the key fields you’ll reference — field names, data types, and any fields that may be null or empty.
Example: “Payload includes: applicant_name (string), applicant_email (string), job_id (integer), resume_url (string, may be null if applicant skipped upload).”
That last clause — “may be null” — is not a detail. It’s routing logic. Which brings us to step three.
Step 3: Write Out the Routing Logic
If the scenario branches, describe every branch. Claude handles routers well — but only if you tell it what conditions create each path.
Don’t say: “Route based on the job type.”
Say: “Router with two paths. Path 1: job_type = ‘hourly’ — send to Slack channel #hourly-ops. Path 2: job_type = ‘salaried’ — send to Slack channel #salary-ops. If job_type is null or any other value, route to Path 2 as the default.”
Every branch needs a condition and a default. If you don’t define the default, Claude will pick one. It may pick the right one. Don’t rely on that.
Complex routing is one of the areas where Claude performs well — if it’s briefed correctly. We’ve covered more on this in our post on building Make scenarios with Claude step by step.
Step 4: Specify the Error Conditions
Tell Claude what to do when something fails. Be explicit about which modules are error-prone and what the recovery path looks like.
Example: “Add an error handler on the HTTP POST module. On error: log the error to a Google Sheet (sheet name: ‘Scenario Errors’, tab: ‘Job Submissions’) and send an email to ops@company.com with the error message and the original payload.”
Claude builds routed error handlers correctly — not generic try/catch, but specific routing per error condition — when you tell it what the conditions are. If you skip this section, you’ll get a scenario with no error handling at all. That’s fine in testing. It’s not fine in production.
If you want to understand what breaks in AI-built scenarios when error handling is skipped, our post on seven things AI-built Make scenarios get wrong covers this in detail.
Step 5: Name the Output Destination and Action
Where does the data end up and what action does it perform? Name the app, the module type, and the specific record type or action.
Weak: “Update the CRM.”
Strong: “Module: HubSpot – Update a Contact. Match on email address. Update fields: Last Application Date (date), Last Job ID (number), Application Status (string, set to ‘Applied’).”
List every field you want written. If you want a field cleared rather than updated, say so. If the record should be created when it doesn’t exist (upsert behavior), say so explicitly — Claude will not assume it.
Step 6: Include the Credential Names
This is the step most people skip. Don’t skip it.
For every app in the scenario, include the connection name exactly as it appears in your Make account. Claude will populate the credential fields with what you provide. If you don’t provide them, you’ll get placeholder text you have to replace manually — which defeats the point of a production-ready output.
Format it as a simple list at the bottom of your brief:
- HubSpot connection: HubSpot – 4Spot Production
- Slack connection: Slack – Ops Workspace
- Google Sheets connection: Google – Ops Account
One line per app. That’s all it takes.
Step 7: List Known Edge Cases
Edge cases are the scenarios within the scenario — the situations where the happy path doesn’t apply. List them explicitly.
Examples:
- “resume_url may be null — skip the file download module and continue.”
- “applicant_email may already exist in HubSpot — use Update, not Create.”
- “job_id will sometimes be a string (‘1042’) instead of an integer — parse to integer before routing.”
Claude is good at inferring missing context and asking clarifying questions when something doesn’t add up. But it can only ask about what it knows is uncertain. Edge cases you don’t mention are edge cases it won’t flag. List them and they get handled in the build. Skip them and you find them in production.

How Do You Know the Brief Worked?
Three signals tell you the brief landed correctly.
First, Claude asks very few clarifying questions. When the brief is tight, there’s nothing to clarify. If Claude comes back with five questions, the brief had five gaps.
Second, the scenario opens in Make with no broken modules — no red warning triangles, no empty credential fields, no undefined variables in filters.
Third, the error handlers are specific. If you asked for routed error handling and the scenario has a single generic error handler, Claude generalized because your error condition spec was thin.
If all three are clean, run a test execution with a real payload. That’s your final confirmation.
What Are the Most Common Briefing Mistakes?
Using app names instead of module types. “Add a HubSpot step” tells Claude nothing. “HubSpot – Search Contacts, match on email” tells it everything.
Describing the goal instead of the logic. “I want applicants to get a confirmation email” is a goal. “Trigger a Gmail – Send an Email module after the HubSpot update, to the applicant_email field, using the template stored in draft ID 17842abc” is logic.
Skipping the data shape. If Claude doesn’t know the field names, it invents plausible ones. They will not match your actual payload.
Omitting credentials. Every missing credential name is a placeholder you’ll fill in manually. For a five-app scenario, that’s five manual steps you could have eliminated.
Describing one path and forgetting the rest. Scenarios branch. Brief every branch — including the default.
