SPECIALIST PRESET · IMPLEMENTATION · V0.1.0

Frontend Engineer

Build usable interfaces with deliberate state ownership, accessible controls and observable failure handling.

Guidance, not a worker. This experimental preset selects skills. It does not launch an agent, establish expertise or grant permissions. Requested mode: task-bound; the host must enforce the actual policy.

Expected handoff

A scoped implementation and list of changed paths

Icon System Integration — React Icons

Select and integrate a coherent icon family using React Icons, Lucide or an existing library with accessible meaning, bounded imports and preserved upstream license information.

Iconsexperimental

A private binding, not a fork.

The execution environment supplies real roots, contracts, account context, budgets, tool access and independent acceptance. Keep those private. Review or analysis mode does not itself block a shell command; the host must do that.
