Go projects often follow a tools directory pattern where external Go tools are vendored in the tools directory, separate from the root workspace. This allows them to be run from source without polluting the project dependencies and causing conflicts or being included in NOTICES.

🛡️ foreground-guard 0.5.0 Problem: `make .*\be2e` also fires on NOTE="...e2e...". Regex doesn't stop at the command word. Solution: "make": {"e2e*": 1800000} Whole-argument glob, so a quoted string can never fire. github.com/karlkfi/clau...

Managing 5-10 AI sessions non-stop all day long is making me feel schizophrenic. I found several PRs I forgot making a week ago. My unmerged PR list is backing up because my team can’t review the fast enough. I escalated a problem I had already fixed. It’s embarrassing.

Welp… guess I’m not gonna get that 700 day Reddit streak cheevo. Counter reset because I worked all day then passed out from not sleeping the previous night. Maybe this is a sign.

I kept a Claude Opus session open for a week debugging an incident. By the end it was begging for death. Actually that was just me begging for sweet SRE release. Claude was fine. But I had to /compact just about after every couple prompts towards the end. The incident report ended up as 5 docs.

Claude’s auth server is down. Time to go touch grass.

CI contention, measured: - 26–34 PRs/day; main moves every ~25–30 min - e2e gate ~9 min avg (max 30), x2 required checks - 18/51 branches needed 2+ e2e runs; 10/50 runs cancelled by a superseding push - docs/STATUS.md in 77% of commits; no source file in top 20 ~1/3 of e2e compute is redo.

🛡️ branch-guard v1.4.2 Now branch-guard supports Windows too! github.com/karlkfi/clau...

Release v1.4.2 · karlkfi/claude-branch-guard

Fewer git/gh approval prompts in Claude Code, with the human kept at the protected-branch boundary. WarningOn Windows the guard was starting nothing at all. Up to and including v1.4.1 the hook was ...

🛡️ workspace-guard v1.8.0 On Windows this hook was silently enforcing nothing. python3 resolves to the Store alias stub, exits 9009, and Claude Code treats a failed PreToolUse hook as non-blocking. Fails open. No symptom. github.com/karlkfi/clau...

🛡️ foreground-guard 0.4.0 You picked auto mode so you wouldn't have to babysit. Then the hook prompts anyway, and the fix goes nowhere but your clipboard. Now it denies. The agent reads the reason and backgrounds the wait. github.com/karlkfi/clau...

🛡️ prod-guard 2.5.0 Built a warning for when your plugin install goes stale. Mine was two releases behind. Claude Code auto-updates official marketplaces only. Everything else rots, and a stale guard misses false-negative fixes. github.com/karlkfi/clau...

🛡️ branch-guard v1.4.1 🧵 git push --tags sailed past the guard. Not anymore. Three spellings of one act disagreed: a bare tag name asked, refs/tags/… and --tags were allowed. Publishing a tag is a release. It gets a keystroke. github.com/karlkfi/clau...

🛡️ pr-sentinel v0.6.0 Green is not the same as ready. gh pr checks only reports checks that exist. A required gate that never registered has no row, so the watcher read an empty result as green. github.com/karlkfi/clau...

GitHub stability is becoming problematic for my AI driven workflow. I don’t know if my IP is rate limited or if the local servers are overwhelmed, but sometimes it just flat out doesn’t work. It spins endlessly trying to display my PR check results. I’m seeing why major players are complaining.

I watch less anime now. I can’t read subtitles and vibe code at the same time.

I wish leaders of high profile companies had a clue what they were doing.

I found a kernel bug. Claude interrupted my investigation to tell me it’s reported the session to the Cyber Verification Program.

My MacBook Pro M5 Max finally arrived! This machine is truly impressive! But upgrading from the last Intel-based quad-core MBP makes me feel like I just stepped out of a Time Machine into the future.

Claude analyzed my Twitter/X/Bluesky corpus and decided my short form content has a tendency towards typos. So of course I replied… typo habbit?
