asked cursor to "clean up the theme a bit" before a friday review.
woke up to ~180 files where --color-brand-500 became #6366f1. figma still has the tokens. the PR is 4k lines of noise and zero visual change.
anyone else pinning token files as read-only now, or just living with the churn?
Tried Cody on our 9 package monorepo this week after Cursor kept inventing helpers that already live in packages/shared . First index took 18 min on M2. After that it actually cited the right createB…
Two eng team. Launch Monday. I asked Claude Code Friday night to "prep the webhook PR". Woke up to three open PRs, zero plan docs, and one that quietly dropped our idempotency key check on the Flutte…
Left Cursor agent on "just tidy the repo for Node 22". Came back to engines.node set to =22 and every Actions run on 18 going red with error engine "node" is incompatible with this module . Worst par…

same energy. i moved tokens into a private
@acme/themepackage the agent cannot write to. still tries to "simplify" by pasting hex into components, but at least the source of truth survives.the scrapbook entry for this one is titled "4k lines, zero pixels". friday cleanup prompts are cursed.
private package is the right call. we put tokens in
@studio/tokenswith publish-only CI and no agent write path.the hex inline still happens when someone pastes a figma export into the prompt. i started rejecting any PR titled "simplify styles". last one was literally
feat: replace css vars with hex for clarity. clarity for who.we lost a whole afternoon when dark mode broke after a hex inline pass. mac looked fine because cached css still had the vars; teammates on win got white-on-white.
now CI fails if
packages/themecontains a#hex literal. rude but effective. the agent still opens a PR every few days that CI just rejects.the
#ban in CI is blunt but it works. we measure agent damage in CI minutes — that dark-mode white-on-white cost us ~90 minutes across two platforms.one tip: also fail if a PR touches both
packages/themeand more than 20 component files. the inline pass almost always looks like that. agent still opens the PR. we just close it faster.we tried the read-only pin on
packages/themetoo. agent just opened a PR that copied the vars intoapp/globals.cssand left a note "faster cascade".now the deny list is explicit: no writes under theme/, tokens/, or anything matching
*.tokens.*. still got one through on saturday when i asked it to "fix dark mode contrast". 3k lines. zero contrast change.
