Feedback Near Trigger

MUST

MUST: Render feedback at its trigger: swap the copy button to an inline checkmark, highlight the erroring input — do not fire a distant toast for a local action.

Display feedback relative to its trigger — show inline confirmation, not distant notifications

Bad

Good

Why it matters

When feedback appears far from the action that triggered it, users may miss it entirely. Showing confirmation inline — like a checkmark replacing a copy button or highlighting the specific input with an error — keeps attention where it belongs.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
