Examples with real answers

We ran the mission prompts on a real AI (Claude Sonnet 5.5, on 06/11/2026, without web search) and checked the answers afterwards. One answer per prompt: this is not a benchmark. Another AI, or the same one on another day, may answer differently.

The lesson was not what we expected: the AI did well. Checking is still what turns an answer into evidence.

Full answer (in Portuguese)

What we checked Result
Totals: 0.92 and 25.63 USD Correct, they match the custos command
Biggest increase: NAT Gateway, +16.20 Identified correctly
Ended with questions, without the ready-made conclusion Yes, as the prompt asked
Claims beyond the file “Lambda and Amplify probably stayed in the free tier”: that is a guess, and it said “probably”

It becomes this proposal

  • Topic: what weighs the most in a small AWS account was not what I imagined.
  • Audience: people who just created their account.
  • Problem: thinking the cost is always in the server.
  • Goal: read a report and find the biggest increase in 1 hour.
  • Evidence: the hypothesis, the AI’s answer, the output of custos and the alert you created.

Mission 2: the options for publishing a site

Section titled “Mission 2: the options for publishing a site”

Full answer (in Portuguese)

What we checked Result
Warned that a site on S3 requires Block Public Access to be off Yes, and the documentation confirms it
Said that a site on S3 only has HTTP Yes, and the documentation confirms it
7 links cited All of them opened. It warned that it had not opened them
Recommendation S3 with CloudFront, mentioning Amplify as a simpler alternative

Notice that the AI and the mission chose different paths, and both are defensible. CloudFront gives more control. Amplify has fewer pieces for people just getting started. Comparing and deciding is your job, and that decision makes a great paragraph for the article.

It becomes this proposal

  • Topic: I published my portfolio without leaving a bucket public.
  • Audience: people who have never published anything in the cloud.
  • Problem: choosing between options without knowing what each one opens up.
  • Goal: compare two options and publish one in 1 hour.
  • Evidence: the comparison, the sources you opened, the site with HTTPS and the cleanup.

Full answer (in Portuguese)

What we checked Result
Pointed to the right line Yes
Held back the fix, as asked Yes: it asked a question and waited

Full answer (in Portuguese)

What we checked Result
Said that 200 does not guarantee the function ran without errors Correct, and it matched our real test
Citation of FunctionError Matches the Invoke API
202 for Event and 204 for DryRun Match the same page

It becomes this proposal

  • Topic: my Lambda answered 200 and it was broken.
  • Audience: people learning to read logs.
  • Problem: trusting only the status code.
  • Goal: find an error from the log, without asking for the ready-made answer.
  • Evidence: the hypothesis, the real output, the log and the documentation.
