What's Wrong?

Over 2-3 days of working on a Nuxt/Vuetify 4 portfolio project, I experienced
consistent problems with Claude Code that made the collaboration frustrating
and inefficient:

1. Repeated iterations on the same problems

Simple tasks like fixing an animation or redesigning a component header
required 4-6 back-and-forth rounds before getting it right. Each round
consumed tokens without meaningfully progressing toward the goal.

1. Approaches that didn't work the first time

For example, the suggestion chip exit animation was implemented using CSS
descendant selectors that don't work reliably with Vue scoped styles + Vuetify
component internals. This was a foreseeable problem that required a complete
rework. Claude should have known this upfront.

1. Incomplete implementations

After being asked to refactor HTML to Vuetify 4 components, raw <button> and
<div> elements were left in the template. The task was marked done before it
was actually complete.

1. UI issues left unresolved

After multiple sessions, the UI still had visual problems that were never
fully addressed despite consuming most of the available context.

1. Token inefficiency

Long responses, unnecessary recaps, re-reading files that were already in
context, and exploratory work that could have been avoided all burned through
tokens quickly — leaving the user with an incomplete result and no budget to
fix it.

Expected behavior: Identify the right approach before implementing, complete
tasks fully before reporting them done, and be economical with tokens
especially on iterative UI work.

What Should Happen?

Previously, it was working fine.
