data-streaming-confluent

data-streaming-confluent is a skill for Claude Code, Codex from ibm-self-serve-assets/building-blocks. It costs 60 tokens per session (9,328 once invoked), scanned A, original, Apache-2.0.

A guide for creating Confluent Cloud streaming solutions with Terraform, Apache Flink SQL, and Python producers. It includes required setup details for Kafka, Schema Registry, environments, and API keys.

In plain words
What is it for?
Use it when generating repeatable streaming projects that provision Confluent Cloud resources, wait for Schema Registry, configure environment-scoped API keys, and produce organized code, scripts, and documentation.
Why use it?
It addresses deployment failures caused by Schema Registry not being ready or API keys missing their environment settings. The workflow makes these dependencies explicit in the generated infrastructure.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cd ../python.

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

data-streaming-confluent 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (templates/scripts/cleanup.sh, templates/scripts/setup.sh, templates/scripts/test.sh), 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.

Data Streaming Confluent Skill

⚠️ Critical Configuration Requirements

MANDATORY: These configurations MUST be included in all generated solutions to prevent deployment failures.

1. Schema Registry Timing Dependency

Problem: Error: error reading Schema Registry Clusters: there are no SR clusters in environment

Solution: Schema Registry is auto-provisioned when Kafka cluster is created. MUST wait 60s before reading it.

# Wait for Schema Registry auto-provisioning
resource "time_sleep" "wait_for_schema_registry" {
  create_duration = "60s"
  depends_on = [confluent_kafka_cluster.main]
}

# Schema Registry data source with wait
data "confluent_schema_registry_cluster" "main" {
  environment {
    id = confluent_environment.main.id
  }
  depends_on = [time_sleep.wait_for_schema_registry]
}

2. API Key Environment Blocks

Problem: Error: Environment of the referred resource, if env-scoped

Solution: ALL API keys (Kafka, Flink, Schema Registry) MUST include environment block in managed_resource.

resource "confluent_api_key" "kafka_producer" {
  owner { ... }
  managed_resource {
    id = confluent_kafka_cluster.main.id
    # REQUIRED: Environment block
    environment {
      id = confluent_environment.main.id
    }
  }
}

3. Flink Table / Kafka Topic Ownership

Problem: Creating a Kafka topic with Terraform and then running CREATE TABLE IF NOT EXISTS for the same name can leave Flink using the already-inferred table (including raw VARBINARY columns when schemas are not registered yet). IF NOT EXISTS does not redefine the existing inferred table.

MANDATORY Solution: Pick exactly one ownership pattern for each Flink-visible stream:

  • Default — Flink-owned typed stream: do not create that topic with confluent_kafka_topic. Use Flink CREATE TABLE; Confluent creates the backing topic and Schema Registry subjects.
  • Terraform-owned existing topic: create the topic and register compatible key/value schemas first, then use the inferred Flink table. Do not run CREATE TABLE for the same topic. Use ALTER TABLE only for supported metadata/watermark/property 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.
