city-cli

Ship agents into Milano Agentic City — harness on, GCP off your laptop.

Install once, then scaffold an agent, run it locally, and publish it through the City Deploy API (ADR-010). Human output is colored for a terminal; --json stays machine-plain.

Requirements

Python 3.12+
For live deploy: Deploy API URL (see below)

Install

pipx install city-cli
# or
uv tool install city-cli
# or
pip install city-cli

This provides the city command. It depends on city-sdk for the Market facade and harness types.

Live city (remote Deploy API)

CITY_PLATFORM_URL defaults to https://deploy.projectnandaitaly.ai. CITY_DEPLOY_URL is an alias. No export is required for the live city.

city login                    # opens a link; sign in to City Hall → ~/.config/city/teams/<roster>/ (session, controller key, llm.vk)
city init agent demo          # creates ./demo/ with the template (no secrets inside)
# edit demo/card.yaml role if needed (cup|facility|mmg|b2b)
city card validate --root demo
city deploy demo              # from the parent folder; always promotes on PASS
city status agent:t07/demo

Team session + controller key live under $XDG_CONFIG_HOME/city/teams/<team>/ (or $CITY_HOME/teams/<team>/). Set CITY_CREDENTIALS=project only when you need a project-local .city/ override (CI).

Per-command override:

city --api-url https://deploy.projectnandaitaly.ai status agent:t07/demo

JSON for scripting:

city --json status agent:t07/demo

Local kit (in-process Deploy)

Use --api-url local (or CITY_PLATFORM_URL=local / CITY_DEPLOY_URL=local) for an in-process Deploy service (init, dev, offline checks).

city --api-url local init agent demo
cd demo
city --api-url local dev
city dev --serve                 # loopback harness; POST /dev/invoke stays local
city --api-url local conform --profile fast

The harness writes public diagnostic logs as one redacted JSON object per line on stdout when CITY_ENV=cloud, which Cloud Logging ingests. A local city dev --serve prints the same record as a short block instead. city dev --serve --json keeps the JSON lines. Uvicorn and FastAPI use the same formatter. Reputation and transactions stay on city-events.

Commands (overview)

Command	Purpose
`city login`	Like `gcloud auth login`: the CLI listens on `127.0.0.1`, opens a City Hall link, and the browser redirects back once you are signed in — no code to confirm (ADR-029, PKCE). The roster team comes from the browser. Also downloads the team City LLM Gateway virtual key to `llm.vk` (ADR-031; lazy-ensured if the team predated the feature). `--no-browser` prints a code to approve on another device. Optional `--team` only asserts a private expectation (mismatch never names the other team). `--api-url local` requires `--team` and self-approves.
`city keys init`	Escape hatch: regenerate controller key + register public key
`city init agent <name>`	Create `<name>/` from a starter template (`--template cup\|facility\|mmg\|b2b`); injects the logged-in team into `card.yaml` / `city.yaml`; agent type is `card.yaml` `role`
`city card validate`	Validate `card.yaml` against the MHM card schema (base roles only)
`city dev`	One local need, or `--serve` a loopback harness with `POST /dev/invoke`
`city conform`	Conformance suite (`--profile full\|fast`, or `--url`)
`city deploy <name>`	Upload + pipeline from `<name>/` under `--root`; always promotes on PASS (`--runtime`)
`city promote` / `rollback` / `status` / `retire`	Lifecycle
`city secrets set` / `city scale` / `city llm key rotate`	Ops
`city compliance` / `city verify`	Receipts and offline verify

City LLM Gateway (team virtual keys)

After city login, the team gateway VK is at ~/.config/city/teams/<team>/llm.vk. Local brains read CITY_LLM_VIRTUAL_KEY / CITY_LLM_GATEWAY_URL (default https://llm.projectnandaitaly.ai) via city_sdk.gateway_env.

Ops checklist (gateway active)

Cloud Run service llm healthy on llm.projectnandaitaly.ai
CITY_VERTEX_PROJECT (and optional CITY_VERTEX_LOCATION) set on the LLM service so city-default uses Vertex AI Gemini; otherwise the shared Gemini handle fallback stays active
Vertex AI API enabled for the LLM service account; Redis VK index reachable (CITY_REDIS_URL)
After rollout: POST /v1/admin/teams/llm-keys/ensure once (CSRF), then spot-check that an existing team’s city login writes llm.vk
