// configurationThe `bob` CLI is not on PATH. Install IBM Bob Shell so `bob --help` works in the same environment as this Next.js server. Baked reports under /demos still work without Bob.

cp .env.example .env.local

// github pull request

Works with any public GitHub pull request (paste the PR URL). Fetches the full unified diff plus up to 10 changed-file snapshots from the PR head via /api/github. Private repos need a token with repo scope. Then Run cascade sends diff + snippets to Bob Shell (bob CLI + BOBSHELL_API_KEY).

MEDIUMDEMO-3
