AI agents for customer support · Part 4 of 14

Writing knowledge an AI agent can use

How to find the answers nobody wrote down, write each one so the agent can use it, and take your macros apart.

The short version

Your agent can only answer from what you wrote down, and it often reads one piece of an article, not the whole page. Five steps get your knowledge ready for it:

  1. Find the answers nobody wrote down
  2. Write one answer per question
  3. Make every piece stand alone
  4. Take your macros apart
  5. Keep one answer, with an owner

Step 1Find the answers nobody wrote down

When your knowledge has no answer, the agent should hand the customer to a person (part 2). Each of those hand-overs names an article to write. So does every reply your team sends from memory, with no article behind it.

The agent finds nothing

A customer asks a new question. The agent searches your knowledge and hands over.

Next time

The agent finds the article

A customer asks the same question, and the agent answers alone.

Every hand-over for a missing answer is an article to write. Write it down once, and next time the agent answers alone.

Step 2Write one answer per question

Title each article with the question as customers ask it, and answer it in the first sentence. Then write out every condition: who it applies to, by when, and the exceptions. An agent can’t apply “usually”.

Written for the agent

Question
Can I return a sale item?
Answer
Yes, within 14 days of delivery, if it is unused.
Conditions
Items marked final sale: no returns. Personalised items: no returns.
Steps
Start it from your order page.
The same policy twice, as an example. An agent can’t apply “usually” or “a reasonable time”, so write down each condition it would otherwise guess.

Step 3Make every piece stand alone

Many agents search your knowledge in small pieces and answer from the best matches. A piece that leans on the paragraph before it loses its meaning. So name the subject in every paragraph, and put in words what a picture or a table shows.

The article: Changing your order

You can change the address until the order is packed.

Changing your order: after that, it can’t be changed. Ask the courier to redirect it.

After what? What can’t be changed?

↓

Written to stand alone

Once an order is packed, its delivery address can’t be changed. Ask the courier to redirect the parcel.

An example. The agent finds the right piece, but “that” and “it” point to a paragraph it never read. Name the subject in every piece.

Zendesk describes its own generative AI this way: your articles are split into chunks, and each reply is written from the article’s title and the chunks that match best. Its guide asks writers to repeat the noun rather than write “it” or “they”.

Step 4Take your macros apart

A macro is written for a person who has just done something. It confirms an action, sets a tone, and often carries a note meant only for your team. Keep its facts as articles. Its limit is a rule (part 1, step 5), and the confirmation should come from the tool that acted.

Macro: refund for a damaged item Hi {name}, sorry it arrived damaged.I’ve refunded {amount} to your card. You’ll see it in 5 to 10 working days.Internal: up to €30, then the team lead. Leave it outA tool does itA rule An article set the tone once, in the agent’s settingsthe agent says so once it’s done (part 7)a limit, checked before it acts (part 8) a fact the customer needs

Macro: refund for a damaged item

Hi {name}, sorry it arrived damaged.

Set the tone once, in the agent’s settings.

leave it out

I’ve refunded {amount} to your card.

The agent says so once it’s done (part 7).

a tool

You’ll see it in 5 to 10 working days.

A fact the customer needs.

an article

Internal: up to €30, then the team lead.

A limit, checked before it acts (part 8).

a rule
One macro taken apart, as an example. Only one line is knowledge. The confirmation belongs to the tool that acts, and the limit is a rule.

In July 2025 Gorgias took macros out of its AI Agent’s knowledge. They had been potentially useful in fewer than 1% of the messages it answered, often led to inaccurate answers, and are “usually written as confirmation messages rather than guidance”.

Step 5Keep one answer, with an owner

When your help center, your website and an old PDF all answer the same question, the agent may quote any of them. Keep one answer, delete the others or point them to it, and name who changes it on the day the policy changes.

An example. When three sources disagree, the agent can’t tell which one is current. Keep one answer, and name who changes it the day the policy does.

Where Himmel fits

The limits you take out of your macros are rules, not knowledge. With Himmel, your team confirms them in plain words, and the agent’s tool checks them before it acts.
