dataset-evaluation
Agent skill fromawslabs/agent-plugins
Validates dataset formatting and quality for SageMaker model fine-tuning (SFT, DPO, or RLVR). Use when the user says "is my dataset okay", "evaluate my data", "check my training data", "I have my own data", or before starting any fine-tuning job. Detects file format, checks schema compliance against the selected model and technique, and reports whether the data is ready for training or evaluation.

1# Workflow Instruction23Follow the workflow shown below. Locate the dataset, check the file type, and resolve any issues with missing files or wrong file types. Determine the fine-tuning model and fine-tuning strategy. Run the appropriate validation based on the model family. Summarize the results: is the dataset ready for fine-tuning?45## Prerequisites67- The SDK environment has been verified (SDK version, region, execution role). If not done, activate the `sdk-getting-started` skill first.89---1011## Workflow12131. **Locate Dataset**:14 - The full path may be a local file path, or an S3 URI15 - Resolve the full path to the dataset file, make sure read permissions are available, and help the user if the file is not found16172. **Determine strategy and model**:18 - File formatting depends on the currently selected fine-tuning strategy and fine-tuning base model.19 - If the strategy and model are already known from the conversation context (e.g., selected via the model-selection and finetuning-technique skills), use them.20 - If not available in context, activate the model-selection and/or finetuning-technique skills to determine them before proceeding.21 - **Exception:** If the user is validating an evaluation dataset (not a training dataset), neither model nor technique is required — the format detector can validate eval format (query/response structure) independently. Do not block on model-selection or finetuning-technique for eval dataset validation.22…
