fabric-network-remediate

fabric-network-remediate is a skill for Claude Code, Codex from PatrickGallucci/fabric-skills. It costs 86 tokens per session (1,425 once invoked), scanned A, original, MIT.

A troubleshooting guide for network problems in Microsoft Fabric, Microsoft’s cloud data platform. It covers connections between Fabric workloads, private networks, DNS, firewalls, gateways, and external services.

In plain words
What is it for?
Use it to investigate notebooks, pipelines, dataflows, OneLake requests, gateways, private endpoints, managed networks, firewall rules, and cross-workspace connections.
Why use it?
It helps locate the cause of timeouts, slow Spark startup, blocked dependencies, failed private endpoints, incorrect DNS routing, and access errors.

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

fabric-network-remediate 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/Test-FabricNetworkHealth.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Microsoft Fabric Network Performance remediate

Systematic toolkit for diagnosing and resolving network performance issues across Microsoft Fabric workloads including Spark, OneLake, Data Warehouse, Pipelines, and Dataflows.

When to Use This Skill

  • Fabric Spark sessions take longer than expected to start (>10 seconds)
  • Connection timeouts to external data sources from notebooks or pipelines
  • Managed private endpoint status shows Pending or Failed
  • DNS resolution returns public IPs instead of private IPs
  • Outbound access protection blocks required dependencies (PyPI, Conda)
  • On-premises data gateway connectivity failures
  • OneLake API calls returning 403 or timeout errors
  • Capacity throttling errors (HTTP 430)
  • Dataflow Gen2 staging failures behind firewalls
  • Cross-workspace environment attachment failures due to network mismatch

Prerequisites

  • PowerShell 7+ with Az module installed (Install-Module Az -Scope CurrentUser)
  • Fabric Admin or Workspace Admin role for network configuration changes
  • Azure portal access for Private Link Service and DNS zone management
  • Network access to run nslookup, Test-NetConnection, and Resolve-DnsName

Step-by-Step Workflows

Workflow 1: Diagnose Spark Session Startup Delays

Spark startup times vary based on networking configuration. Consult the reference table:

Scenario Typical Startup Time
Default settings, no libraries 5-10 seconds
Default settings + library dependencies 5-10 sec + 30 sec-5 min
High traffic in region, no libraries 2-5 minutes
High traffic + library dependencies 2-5 min + 30 sec-5 min
Network security (Private Links/VNet) 2-5 minutes
Network security + library dependencies 2-5 min + 30 sec-5 min

Run the diagnostic script for automated assessment:

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.
