When git add -A Sweeps Up .bak Backups — The Quiet Trap of In-Place Fix Scripts
How .bak backups left by sed -i and homegrown --fix scripts get silently swept into production by git add -A, why it is so easy to miss, and how scoped adds and .gitignore close the gap for good.
When Yesterday's Article Bleeds Into Today's — The Stale Fixed-Name Temp File Trap
In a Claude Code automation pipeline, a fixed-name temp file kept stale content from the previous run and leaked old body text into a completely different article. Here is why the write fails silently, and how unique names plus a post-write grep check prevent it.
When git push Says Success but Nothing Lands — the Silent commit Failure in Claude Code
git push prints Everything up-to-date and exits zero, yet your changes never reach the remote. Here is why commit silently fails on a fresh sandbox clone, and how to verify a real push with SHA comparison.
Fixing Claude Code's 'Credit balance is too low' Error
You launch Claude Code and it immediately stops with 'Credit balance is too low' — even though you have an active subscription.

An automation that ran fine yesterday suddenly dies on detected dubious ownership in repository. Here is what actually triggers it, the safe.directory fix, and how it differs from a real Permission denied.
Diagnosing invalid_request_error When You Pass an Image URL to the Claude API
When the Claude API rejects an image you passed via `source.type: url`, the root cause almost always lives in one of four buckets: scheme, MIME, size, or reachability. Here is the diagnostic order I use in production.
Why JSON.parse Fails on Claude API Streaming tool_use Arguments — and How to Fix It
When you stream a Claude API response with tool_use, calling JSON.parse on each input_json_delta throws SyntaxError. Here is the correct way to assemble partial_json fragments, plus disconnect handling.
When Claude Code's Bash Tool Hits Permission Denied on /tmp — A $HOME/repos Fallback Pattern
A practical look at why git clone inside Claude Code's sandboxed Bash sometimes fails with Permission denied on /tmp, and how a tiny $HOME/repos fallback keeps unattended schedules alive across four indie sites.
Fixing Garbled Japanese Files in Claude Code — Identifying Shift-JIS vs UTF-8 and Converting Safely
When the Read tool spits out characters like 縺ゅ＞縺ゅ＞ instead of Japanese, the file is almost always Shift-JIS or EUC-JP being misread as UTF-8. Here is a practical workflow to detect the real encoding and convert it for Claude Code, drawn from running a Japanese wallpaper app since 2014.
How I Stopped Claude Code's 'File has been modified since read' Error From Recurring
If Claude Code keeps tripping over 'File has been modified since read it' partway through a long session, the cause usually narrows down to three settings. Here is what actually worked in my own setup.
