fabric-eventstream

fabric-eventstream is a skill for Claude Code from wardawgmalvicious/agent-config. It costs 242 tokens per session (2,518 once invoked), scanned A, original, MIT.

A Microsoft Fabric Eventstream guide for routing live events from sources such as Kafka, Event Hubs, databases, IoT devices, HTTP, or MQTT. Microsoft Fabric is Microsoft's data and analytics platform; Eventstream sends incoming events to places such as a Lakehouse or Eventhouse.

In plain words
What is it for?
Use it to design or edit event sources, filters, aggregations, and destinations for real-time data flows in Microsoft Fabric.
Why use it?
It clarifies when live event routing is appropriate and when batch copying, Spark, SQL, or database mirroring is a better fit. It also explains that changes need to be published before they take effect.

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-eventstream 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fabric Eventstream

Streaming-data ingestion item that pulls events from a wide source surface (CDC / Event Hubs / Kafka / IoT / HTTP / MQTT) and routes them into Fabric destinations (Lakehouse, Eventhouse, Activator, derived stream, custom endpoint). Authoring is graph-based: source nodes → optional transformations → destination nodes, edited then published to go live.

When to use vs not

Use Eventstream when the data is arriving as events and needs routing or transformation before it lands. Skip it when the data is bulk / batch (use a Data Pipeline Copy activity), already in the lake (use Spark / SQL directly), or when the only consumer is a Mirrored Database in append-only mode (mirroring lands data straight in OneLake without an Eventstream).

For real-time analytics on the resulting events, pair an Eventstream with fabric-eventhouse (KQL Database). For real-time rules, pair with an Activator destination (covered below).

Authoring model

  • Edit mode vs Live mode: changes only take effect after Publish. New nodes added in Edit mode produce no traffic until publish.
  • Sources = where events come from. Transformations = inline filter / aggregate / GroupBy / Manage Fields / SQL. Destinations = where events go. Each destination can have its own format (Delta / JSON / Avro) where applicable.
  • Permissions: workspace Contributor or higher to author; Viewer can read Data insights monitoring on a published stream.
  • Virtual-network injection (private-network sources): use Eventstream connector VNet injection for sources behind a firewall — see Microsoft Learn.

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.
