foundry-network-runbook

foundry-network-runbook is a skill for Claude Code, Codex from aiappsgbb/awesome-gbb. It costs 236 tokens per session (6,223 once invoked), scanned A, original, MIT.

An operations guide for diagnosing network failures in Microsoft Foundry after deployment has succeeded. It checks issues such as DNS, private networks, firewall rules, permissions, and agent network resources.

In plain words
What is it for?
Use it when Foundry returns network-related 503 errors, private DNS configuration errors, disconnected network links, blocked traffic, or failures creating agent network resources.
Why use it?
A deployment can report success while model calls or project connections still fail because traffic cannot reach the right service.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

foundry-network-runbook scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Foundry Network Runbook — Diagnose connectivity failures after the deploy succeeds

1. Goal

This runbook is for the on-call engineer who just got the page "Foundry agent is up but inference / project connection / model call is failing over the network." The foundry-vnet-deploy succeeded (or the foundry-caphost-lifecycle create returned Succeeded), the resources exist in the portal — but something at the network layer is wrong: DNS resolves to the wrong IP, an NSG drops the packet, an RBAC role is missing for a private DNS zone, a VNet peering went Disconnected, the caphost subnet is wedged. You have ≤ 30 minutes to isolate the layer before escalating.

This runbook is not a telemetry guide (foundry-observability covers App Insights + OTel wiring), not a deploy guide (foundry-vnet-deploy covers Day-0; foundry-caphost-lifecycle covers Day-2 lifecycle), not an auth / JWT troubleshoot for the Citadel APIM gateway (that's citadel-spoke-onboarding), and not an SDK / quota troubleshoot. If the symptom is not a network-layer symptom, jump to § 8 — the cross-reference index points you at the right skill.

2. When to use this runbook

Trigger this runbook when all of the following are true:

  1. The Foundry deployment (or hosted-agent create, or caphost create) reported Succeeded in ARM and the resources are visible in the portal.
  2. Something fails downstream at the network layer: 503 from inference, DNS resolving to a public IP, project connection showing red, a private endpoint missing or not approved, a fresh redeploy hitting Subnet already in use.
  3. You have a baseline of "this worked yesterday" or "the deploy just completed, why doesn't it work now?" — i.e., the failure mode is operational (post-deploy), not a code or SDK bug.

If the failure is during the Bicep az deployment group create itself, use foundry-vnet-deploy § 10b (safe retry). If the failure is a hosted-agent-creation 403 with MI provisioning failed or NIC provisioning failed, this runbook's § 4 matrix points you back to foundry-vnet-deploy § 8b for the RBAC fix.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
