Answer 10 practical questions and see which topics to study next.

Check your judgement across evidence, tool permissions, evaluation, security and human review.

1. A policy analyst asks Claude to summarise a 70-page report. Which review best tests factual accuracy?

Check whether the summary sounds confidentTrace each material claim to a page or quoted passageAsk Claude to make it shorter

Answer and explanation

Material claims need evidence a reviewer can trace to the source.

2. A tool can issue customer refunds. Which design gives the safest boundary?

Let the model refund any amountRequire human approval of the amount and customer IDPut the policy in a longer prompt

Answer and explanation

A consequential business action needs validated parameters and an approval gate.

3. A workflow returns stale prices from uploaded files. What should the team check first?

Source owner, version and review datePrompt adjectivesBullet formatting

Answer and explanation

Knowledge quality depends on source ownership and currency.

4. A tool call omits a required field. What should the application do?

Invent a defaultReturn a structured error and allow a bounded repairRepeat forever

Answer and explanation

Structured errors and bounded retries support correction without guessing or loops.

5. A procurement assistant reads supplier emails that may contain malicious instructions. Which control addresses this?

Treat retrieved content as untrusted and restrict toolsIncrease temperaturePut every email in the system prompt

Answer and explanation

External content can carry prompt injection. Tool permissions belong outside the model.

6. A team changes an invoice extraction prompt. What is the strongest release check?
