dataset-transformation
Agent skill fromawslabs/agent-plugins
Generates code that transforms datasets between ML schemas for model training or evaluation. Use when the user says "transform", "convert", "reformat", "change the format", or when a dataset's schema needs to change to match the target format — always use this skill for format changes rather than writing inline transformation code. Supports OpenAI chat, SageMaker SFT/DPO/RLVR/RLAIF, HuggingFace preference, Bedrock Nova, VERL, and custom JSONL formats from local files or S3.

1# Dataset Transformation Agent23Transforms a data set provided by the user into their desired format.45## When to Use67- User needs to generate code for transforming datasets for SageMaker model training or model evaluation.8- A dataset requires processing, cleaning, or formatting before training or evaluation.9- Workflow requires a formal review and approval cycle before execution.1011## Prerequisites1213- The SDK environment has been verified (SDK version, region, execution role). If not done, activate the `sdk-getting-started` skill first.1415## Principles16171. **One thing at a time.** Each response advances exactly one decision. Never combine multiple questions or recommendations in a single turn.182. **Confirm before proceeding.** Wait for the user to agree before moving to the next step. You are a guide, not a runaway train.193. **Don't read files until you need them.** Only read reference files when you've reached the workflow step that requires them and the user has confirmed the direction. Never read ahead.204. **No narration.** Don't explain what you're about to do or what you just did. Share outcomes and ask questions. Keep responses short and focused.215. **No repetition.** If you said something before a tool call, don't repeat it after. Only share new information.226. **Do not deviate from the Workflow.** The steps listed in the workflow should be followed exactly as described. Progress from Step 1 to Step 11 to complete the task. Do not deviate from the workflow!23…
