BB msk-migration

Use this skill to assess and plan a migration from AWS MSK (Managed Streaming for Apache Kafka) to Confluent Cloud. Triggers on user intent like "migrate MSK to Confluent Cloud", "move off MSK", "MSK to CC cutover", "Zero-Cut migration from MSK", "kcp scan my MSK", or any discussion of MSK-to-CC assessment, planning, cluster sizing, Cluster Linking setup, Gateway-based switchover, or post-cutover validation. Do NOT trigger for non-MSK Kafka sources (open-source Kafka, Aiven, Confluent Platform, Redpanda) — this skill is MSK-only. Do NOT trigger for greenfield Confluent Cloud projects with no existing Kafka source. Do NOT trigger for general Kafka programming questions (producer/consumer code, Kafka Streams) unrelated to migration.

How to improve

  1. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
For the model run — optional
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec

  • warning body-long SKILL.md body ≈ 15653 tokens (recommended < 5000); move details to references/

Process rating: all ten parameters 70/100

  • 0Result and completion. Does not say what the result is
  • 40Execution cost. Instruction body is 15653 tokens: crowds the task out of the window
  • 60Tools and files. Uses tools (bash, web, python, node) that frontmatter does not declare
  • 70Inputs and preconditions. Inputs and preconditions are listed
  • 85Steps. 69 steps, 3 vague phrases
  • 100When it triggers. States when to use and when not to
  • 100Failures and branches. 6 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • 100Running it twice. Mutating operations check current state
  • 100Progress reporting. Reports progress
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 12 top-level sections: this looks like several domains in one skill
  • low No test case covers injection arriving through data

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
