fabric-spark-compute-remediate

fabric-spark-compute-remediate is a skill for Claude Code, Codex from PatrickGallucci/fabric-skills. It costs 92 tokens per session (1,505 once invoked), scanned A, original, MIT.

A troubleshooting guide for Apache Spark compute in Microsoft Fabric. Spark is a system that runs data-processing jobs across multiple machines, while Fabric is Microsoft's cloud analytics platform.

In plain words
What is it for?
Use it to investigate HTTP 430 errors, slow or stuck sessions, failed environment publishing, undersized pools, library delays, and VNet or Private Link provisioning issues.
Why use it?
It helps diagnose throttling, queued jobs, slow startup, autoscaling, capacity, environment, library, and networking problems.

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-spark-compute-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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/Get-FabricSparkCapacity.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 Spark Compute remediate

Structured diagnostic workflows for resolving Apache Spark compute issues in Microsoft Fabric Data Engineering and Data Science workloads.

When to Use This Skill

  • Spark jobs fail with HTTP 430 throttling or TooManyRequestsForCapacity errors
  • Notebook or Spark job sessions are slow to start (>30 seconds)
  • Environment publishing fails or hangs
  • Autoscale is not scaling up or down as expected
  • Jobs are queued indefinitely or expiring after 24 hours
  • Custom pool creation fails or pools are undersized
  • Library installation causes session startup delays
  • Capacity appears exhausted despite low job counts
  • VNet/Private Link provisioning adds unexpected delays
  • Burst factor or job-level bursting behavior is unclear

Prerequisites

  • Workspace Admin or Capacity Admin role in Microsoft Fabric
  • Access to the Monitoring Hub for active Spark sessions
  • Access to Workspace Settings > Data Engineering/Science
  • Knowledge of current Fabric capacity SKU (F2 through F2048)

Quick Diagnostic: Identify Your Issue

Start here. Match your symptom to a diagnostic path:

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
