Implementation sub-skill: Frontend

Builds the UI against the API backend-implementation exposed. The third of implementation's four sub-skills.

In one minute

A sub-skill of Implementation, invoked third of its four, after Backend.
Checks which endpoints the backend actually shipped, not just what the plan called for. Plans and code drift, and this is the sub-skill positioned to notice.
Flags a planned feature with no working endpoint instead of building UI against an assumption that will fail in Integration & deployment.

Read docs/product/definition.md for the core features, and check which endpoints backend-implementation actually shipped, not just what was planned.

Build the UI those endpoints support.

Flag any planned feature whose endpoint does not exist yet, instead of building against an assumption.

Where it fits

Invoked by Implementation, third of its four sub-skills, after Backend. Hands off to Integration & deployment, which runs all three built pieces together.
