Agent Fresh Operate

When To Use

Use this skill to operate a clean agent VM lifecycle on the operator/dev VM:

• First-time fresh-setup on a project alias
• Teardown → redeploy loops (“reproduce from scratch”)
• Validate /api/models and /api/chat after deploy
• Debug destroy/fresh-setup failures (IAM, orphan VMs, ingress rules)

For chat UX, API shapes, and Rerun iframe behavior, use npa-agent. For npa configure / object-storage provisioning, use nebius-infra.

Entry Points

• npa/.venv/bin/npa agent fresh-setup — initialize project env + deploy + bootstrap
• npa/.venv/bin/npa agent destroy — npa-driven teardown (ingress cleanup, TF destroy, orphan VM delete)
• npa/scripts/agent_fresh_setup_loop.sh — destroy → fresh-setup → smoke chat (loop until success)
• npa/scripts/agent_mature_verify_loop.sh — bootstrap-first mature loop (existing agents; not fresh deploy)

All npa agent … and nebius commands run on the operator/dev VM with ~/.npa/config.yaml and ~/.npa/credentials.yaml. Cloud agents sync the target branch to the dev VM before live tests.

Procedure

1. Preconditions (dev VM).

   cd ~/nebius-physical-ai
   git checkout <branch> && npa/.venv/bin/pip install -e npa -q
   nebius profile activate "${NPA_NEBIUS_PROFILE:-npa-mk8s}"
   export NPA_NEBIUS_PROFILE="${NPA_NEBIUS_PROFILE:-npa-mk8s}"
   export NPA_SSH_KEY="${NPA_SSH_KEY:-$HOME/.ssh/id_ed25519}"
   

2. Teardown (npa-driven — no manual nebius vpc edits).

   npa/.venv/bin/npa agent destroy --project <alias> --name agent
   

3. Fresh deploy.

   npa/.venv/bin/npa agent fresh-setup \
     --project <alias> --name agent \
     --project-id <project-id> \
     --tenant-id <tenant-id> \
     --region us-central1
   

   Expect compute PermissionDenied with VM SA attachment on some cross-project profiles; npa retries apply without attached service_account_id.

4. Smoke gate (default “done” for fresh deploy).

   source ~/.npa/agents/<alias>/agent/auth.env
   BASE="$(npa/.venv/bin/npa agent status --project <alias> --name agent --json \
     | npa/.venv/bin/python -c 'import json,sys; print(json.load(sys.stdin).get("public_url","").rstrip("/"))')"
   curl -sk -u "${AGENT_USER}:${AGENT_PASSWORD}" "${BASE}/api/models"
   curl -sk -u "${AGENT_USER}:${AGENT_PASSWORD}" -H 'Content-Type: application/json' \
     -d '{"messages":[{"role":"user","content":"Say hello in one short sentence."}]}' \
     "${BASE}/api/chat"
   

5. Optional full gates.

   • Grounded chat: ask “what is the current sim2real status” → "grounded": true
   • Live regression: NPA_AGENT_CHAT_LIVE=1 npa/.venv/bin/npa agent verify-live --project <alias> --name agent
   • Mature loop: bash npa/scripts/agent_mature_verify_loop.sh (bootstrap-first)

6. One-command loop.

   export NPA_AGENT_PROJECT=<alias> NPA_AGENT_NAME=agent
   export NPA_AGENT_PROJECT_ID=<project-id> NPA_AGENT_TENANT_ID=<tenant-id>
   export NPA_AGENT_REGION=us-central1 NPA_NEBIUS_PROFILE=npa-mk8s
   bash npa/scripts/agent_fresh_setup_loop.sh
   

Verify Tiers

Tier	Checks	Use when
Smoke	status --json, /api/models, hello /api/chat	Fresh deploy validated
Grounded	sim2real status chat → grounded: true	Chat router wired
Live	verify-live	Pre-merge regression
Mature	agent_mature_verify_loop.sh + Franka	Chat/router code changes

Do not block a smoke deploy on verify-live UI wiring markers alone.

Gotchas

• Profile vs project. Cross-project deploy needs a profile with compute IAM on the target project (commonly npa-mk8s). cursor-sa may lack VPC/compute on foreign projects. Never use tle in scripts (interactive auth hang).
• Compute PermissionDenied + SA. First TF apply may fail attaching npa-agent SA to the VM; npa retries without SA attachment. Bare compute denial → stop and report IAM gap to operator.
• Destroy: disk/SG in use. Orphan cloud VM may exist outside TF state after a failed apply/rollback. npa agent destroy deletes matching instances by name before TF destroy; retry destroy if preconditions fail once.
• fresh-setup --replace. Destroy must run before updating project env (otherwise TF backend keys drift mid-destroy).
• 502 / SyntaxError on chat. Re-bootstrap; check embedded \n escaping in bootstrap backend.py template.
• Ingress rules. Stale allow-npa-* rules can block security-group delete; destroy path removes npa-managed ingress first.
• Cloud agent → dev VM. Sync branch (git pull or tar/scp), confirm npa agent --help lists fresh-setup, then run live loop on dev VM.

Symptom → Action

Symptom	Action
PermissionDenied: service compute then success after retry message	Expected SA-attachment retry; no action
PermissionDenied: service compute on retry without SA	Operator IAM on target project
Agent config not found after destroy	Run fresh-setup
Destroy fails, instance name agent-<alias>-agent still listed	Re-run npa agent destroy (orphan cleanup)
Chat 502, health false	npa agent bootstrap --project <alias> --name agent
verify-live UI version mismatch but chat OK	Smoke tier passed; fix UI marker separately
