agent-vercel

JSON in, JSON out, no interactivity. Lists are NDJSON (one object per line, then {"@pagination":…} when more pages exist); single resources are NDJSON by default (one line — pass --format json for the pretty object). Errors are JSON on stderr with fixable_by: agent|human|retry and a hint.

Get (single + multi). get <id>... takes one or more ids and returns one result per id, in input order. Default output is NDJSON: one line per id — the record, or {"@unresolved":{"id","reason","fixable_by","hint"?}} for an id that couldn't be resolved (e.g. not found / bad id). --format json|yaml collapses to one {"data":[…], "@unresolved":[…]} envelope. Item-level misses stay on stdout and exit 0; only a command-level failure (auth, network) goes to stderr with exit 1 and empty stdout.

env get <project> <key>... fixes the project scope first, then resolves 1..N keys from that project's vars — one NDJSON record (or @unresolved) per key.
