Prompting recipes
Asks that work well, and the tool calls they turn into.
Build a list without prospecting your customers
Upload our customers from this CSV as an exclusion list that always applies. Then find machine builders in Germany and Austria that sell to battery cell makers, and export everything above 0.6 similarity.
create_list (kind exclusion, auto_exclude: true) → search_companies with two clauses
(production machinery manufacturer on summary/offerings, lithium-ion battery cell manufacturers on
customers) and filters: {country: ["DE","AT"]} → start_export with the same arguments → get_job.
Lookalikes of your best customers
Here are our ten best customers. Find 50 companies like them in the Nordics, excluding our customers.
find_similar with the ten domains (or a seed_list) and filters: {country: ["SE","NO","DK","FI"]}.
Seeds never come back; with seed_list the whole list is excluded too.
Sharpen a search with feedback
These five are exactly right, these three are not — refine.
search_companies again with like and not_like. The response says which ten companies to label next
(feedback.label_next); eight right and eight wrong examples typically lift precision well above the first
ranking.
Size before you pull
How many software companies are there in Hungary, by size?
count_companies with filters: {country: "HU"} and group_by: ["headcount"] — free, and it tells the agent
whether an export is 500 rows or 50,000.
One message per segment
Split this list into groups I can write different e-mails to.
segment_companies with list_id (or search). Rule-based segments come with a rule that re-selects the
segment in search_companies / start_export.
Tips for agents
- Give each dimension of a question its own clause: what they do and who they sell to are two clauses.
- Never guess a filter value: call
list_filter_valuesfirst. Values are case-sensitive. - Prefer literal
excludephrases (is a webshop,to consumers) over semantic exclusion for roles. - For more than 100 results use
start_export, not repeated searches.
