/just-vibe:profile Set frontend-engineer for this task. Add a filterable catalog while preserving deep links.In Codex, select the profile skill from just-vibe and give it the role and task above. Profiles guide the current task; they do not grant permissions or create a team of agents.
What this role pays attention to
- Trace component state, URL state and server state separately.
- Preserve keyboard interaction, responsive behavior and loading/error/empty states.
Decision guidance
Keep state local until multiple owners or navigation require a wider lifetime.
Concrete contribution
For a feature request, produce an interaction/state map tied to components, including stale responses, URL restoration and keyboard recovery; use it to choose the smallest UI change.
Scope boundary
Do not replace the design system or state library merely to implement a feature.
Relevant checks
- Exercise the user flow at narrow and wide widths.
- Reproduce stale requests and failed submissions where relevant.
