Three bugs that looked fixed from the wrong vantage point. An unquoted YAML date that crashed the public homepage one month after we wrote a blog post about the same bug. A model string that worked until its deprecation date passed. A security commit that stacked three invisible failures on top of each other. And a lesson about what accumulates when you build fast with agents.
One missing pair of quotes in one frontmatter field took down the admin drafts page. YAML 1.1 auto-parsed the date to a JS Date object, formatDate called .includes on it, and the route 500'd. Here's the bisect from a mobile screenshot to a one-line fix, why only the drafts page broke, and the lesson about trusting types at the YAML boundary. Part two of a two-part Friday Fixes — see #1 for the scheduled-publish workflow bugs that landed the same day.
The scheduled-publish GitHub Action broke twice in nine days. Bug one: a grep that matched body text instead of frontmatter, triggered by a post about the feature itself. Bug two: a dead-code line introduced by the fix for bug one — racy under set -euo pipefail, probabilistically silent for eight days, then 42 consecutive failures with zero notifications.
I pointed a current-gen AI agent at a fitness tracker I vibe coded a year ago. Five PRs later: security holes patched, a 1,300-line component broken apart, sync queries batched, and accessibility fixed. Here's what the audit found, how it was structured, and why every vibe coded app deserves a spring cleaning.
I asked an AI agent to turn off my RGB lights on Linux. 85 terminal commands, 35 failures, 4 hangs, 2 dead download links, one wrong build system, and the GPU is still glowing. This is the post.
Four bugs that were silently breaking things for days: a deploy that only crashes on new images, a shell guard that eats your auth tokens, a publish date frozen at draft creation, and a homelab with no emergency remote access. Plus: capacity planning for when you're running AI workspaces on a single machine.
