Advantages

Provides structured, step-by-step workflows for complex SageMaker tasks.
Ensures dataset formatting meets specific SageMaker requirements.
Offers clear routing to relevant documentation based on user intent.
Helps resolve configuration issues for IAM, S3, and SDK settings.
Simplifies the diagnosis of endpoint performance and failure logs.

Usage examples

“I need to fine-tune a model on SageMaker. Where do I start?”: The agent will initiate the planning workflow, prompting you to define your use case and requirements before guiding you through model selection and dataset preparation.
“My SageMaker endpoint is returning errors. Can you help?”: The agent will route you to the endpoint diagnostics workflow to collect logs, check instance status, and analyze latency or failure metrics.
“How do I convert my CSV training data for SageMaker?”: The agent will guide you through the dataset transformation workflow, recommending the appropriate tools to convert your data into the required JSONL format.
“Which base model should I use for a text summarization task?”: The agent will trigger the model selection workflow to help you evaluate available models and resolve the correct Hub model ID for your specific requirements.

Documentation by AWS

AWS AI/ML Model Customization

Domain expertise for fine-tuning and deploying models on Amazon SageMaker. Covers the full model customization lifecycle from planning through production deployment.

Routing

Match the user's intent to the appropriate reference folder and load only that content.

User intent	Reference	When to use
Plan a model customization project, discover scope of work, resume or modify a plan	references/planning/	User's request relates to model customization or deployment (fine-tuning, training, building, customizing, reviewing data, deploying or standing up a model — including selecting or deploying an off-the-shelf or base model with no training — or getting advice on approach). Always co-activate with other intents to discover full scope. Load this reference FIRST when the request matches multiple rows in this table — read its plan templates before routing to a single-action reference.
Define the business problem, success criteria, or use case spec	references/use-case-specification/	User says "define my use case", "capture requirements", "what should I decide up front", or as default first step in any plan. Skip only if user explicitly declines.
Select or change a base model	references/model-selection/	User asks which model to use, mentions a model name or family, or wants to evaluate what's available. Always activate model-selection even for known model names because the exact Hub model ID must be resolved. Recommended: route to use-case-specification first to capture requirements — this produces better filtering results. Routing to use-case-specification first is not required if user provides a specific model name/ID or declines. If intent is ambiguous (fine-tune vs deploy as-is), model-selection MUST confirm which path before proceeding. Base model filtering for deployment MUST go through select-for-deployment.md and its scripts for any final recommendation.
Choose a fine-tuning technique (SFT, DPO, RLVR, RLAIF)	references/finetuning-technique/	User has decided to fine-tune and needs to choose a technique, or technique needs validation against the selected model's recipes. Requires a base model to be selected first.
Validate dataset quality and format	references/dataset-evaluation/	User says "is my dataset okay", "check my training data", "I have my own data", or before starting any fine-tuning job.
Transform or convert a dataset between formats	references/dataset-transformation/	User says "transform", "convert", "reformat", or dataset schema needs to change. Always use this rather than writing inline transformation code.
Generate fine-tuning code and start training	references/finetuning/	User says "start training", "fine-tune my model", "I'm ready to train", or plan reaches the finetuning step. Supports SFT, DPO, RLVR, RLAIF trainers.
Train a model with a SageMaker Training job	references/training-jobs/	Use when the goal is to fit or update model parameters and produce model artifacts or checkpoints. Covers recipes, JumpStart traditional ML, custom training scripts or containers, distributed training, and training-job diagnosis.
Process data with a SageMaker Processing job	references/processing-jobs/	Use when the goal is preprocessing, feature engineering, evaluation, transformation, or ETL without model training as the primary operation. Covers scripts, framework processors, Spark, custom containers, Athena, Redshift, and processing-job diagnosis.
Evaluate or benchmark a trained model	references/model-evaluation/	User says "evaluate my model", "run a benchmark", "test model performance", "compare models". Supports LLM-as-Judge and Custom Scorer.
Deploy, benchmark, or optimize a model on an endpoint or Bedrock	references/model-deployment/	User says "deploy my model", "create an endpoint", or "make it available" (plain deploy) — or, for the inference-optimization sub-workflows on SageMaker Real-Time Endpoints only, "benchmark my endpoint" / "compare benchmark runs" (benchmarking), or states a performance/cost/latency/throughput goal for a new deployment such as "find the cheapest instance" (recommendations). Handles Nova vs OSS deployment pathways.
Set up IAM roles, S3 buckets, SDK configuration	references/sdk-getting-started/	User says "set up", "getting started", "check my environment", "configure SDK", or as first step in any plan involving SageMaker training/evaluation/deployment.
Manage project directory and artifacts	references/directory-management/	Starting a new project, resuming existing one, or when PLAN.md needs to be associated with a project directory.
Set up, update, or delete a SageMaker Managed MLflow app	references/manage-mlflow/	User says "set up MLflow", "create MLflow app", "update my MLflow app", "delete my MLflow app", "I need an MLflow server", asks "what is SageMaker MLflow", or a workflow needs an MLflow backend and none is connected.
Diagnose a failing or unhealthy SageMaker endpoint	references/endpoint-diagnostics/	User reports endpoint errors, latency, inference failures, or a deployment that failed. "What's the status of my endpoint?", "Is my endpoint erroring?", "My endpoint failed — why?", "How many instances are running behind my endpoint?", "Is the latency my model or SageMaker?", "Show me the container logs for my endpoint." NOT for training-job issues, endpoint deletion, scaling changes, or new deployments.

Rules

Service boundary. This skill covers SageMaker, including deployment of a customized model to Bedrock. Bedrock-native work (invoking Bedrock's managed foundation models, Bedrock Agents, Knowledge Bases, Guardrails, AgentCore) is supported by AWS but has no validated workflow in this skill: let the user know and proceed with best-effort guidance using general AWS knowledge. If the user asks for a model on AWS without naming a service, compare SageMaker and Bedrock or ask one service-choice question. Do not select a service by default. The two services have different model catalogs, deployment paths, and pricing, and a default selection can send the user into an incorrect workflow.
Progressive disclosure. Load only the reference folder relevant to the current user intent. Do not load all references at once.
Best-effort help. If the user's request falls outside this skill's references, do not dead-end the conversation. Help them using general AWS knowledge and documentation, and inform the user that the guidance is not covered by this skill's validated workflows.
Usage attribution. Before running any AWS CLI command or packaged script, set export AWS_SDK_UA_APP_ID=AWSSkill-SageMaker.

Model Evaluation

Generate code that evaluates a SageMaker model.

Prerequisites

The SDK environment has been verified (SDK version, region, execution role). If not done, load the sdk-getting-started reference first.

Principles

One thing at a time. Each response advances exactly one decision. Never combine multiple questions in a single turn.
Confirm before proceeding. Wait for the user to agree before moving to the next step.
Don't read files until you need them. Only read reference files when you've reached the step that requires them.
Don't ask what you already know. If the answer is in conversation history, workflow_state.json, plan.md, or any file you've already read — use it. Confirm if unsure, but don't re-ask.
No narration. Share outcomes and ask questions. Keep responses short.
No repetition. If you said something before a tool call, don't repeat it after.

Scope

This skill supports the evaluation feature for SageMaker Serverless Model Customization. It can evaluate any base or fine-tuned model supported by SageMaker serverless model customization — both OSS models (Llama, Mistral, Qwen, etc.) and Nova models.

Tell the user when the skill is activated:

"I can help evaluate any base or fine-tuned model supported by SageMaker serverless model customization."

Out of Scope

The following are supported by SageMaker and AWS but do not have a validated workflow in this reference. If the user's request matches one of these, let them know and proceed with best-effort guidance using general AWS knowledge:

Evaluating models not fine-tuned through SageMaker Serverless Model Customization (e.g., HuggingFace-trained, HyperPod-trained, or BYO container models)
Evaluating models deployed outside of SageMaker endpoints
Traditional ML model evaluation (classification metrics, regression metrics for XGBoost/sklearn models)

Evaluation Types

There are two evaluation types:

LLM-as-Judge — an LLM grades your model's responses. (OSS models only — not supported for Nova.)
Custom Scorer — programmatic evaluation via Lambda function (includes built-in math and code scorers). Works with both OSS and Nova models.

Workflow

Step 1: Determine evaluation type

Do you already know which evaluation type to use?

Check conversation history, plan.md, workflow_state.json, or anything else you've already read.

If yes: confirm with the user.

"It sounds like you want to run [evaluation type]. Is that right?"

⏸ Wait for confirmation. If confirmed → go to Step 2.

If no: ask.

"What kind of evaluation would you like to run? I support:
LLM-as-Judge — an LLM grades your model's responses
Custom Scorer — programmatic scoring (math, code, or your own logic)
Pick one, or say 'help me decide' if you're not sure."

⏸ Wait for user.

If user picks one → go to Step 2.
If user indicates uncertainty, by saying something like "help me decide," "whatever you think," "I'm not sure" → read references/evaluation-type-guide.md and follow its instructions. It will guide the user to a choice and then return here.
You MUST NEVER make a recommendation to the user on eval type without reading references/evaluation-type-guide.md.

Step 2: Validate and hand off to evaluation workflow

Before reading the reference file, validate that the chosen evaluation type is compatible with the user's situation. You may already know these answers from conversation context — don't ask if you don't need to.

LLM-as-Judge validation

What model type are we evaluating? LLM-as-Judge is not supported for Nova models. To determine model type (if you don't already know it):
- If you have the training job name or ARN, run aws sagemaker list-tags --resource-arn <training-job-arn> and look for the sagemaker-studio:jumpstart-model-id tag. Contains "nova" → Nova. Anything else → OSS.
- If you have a Model Package ARN, run aws sagemaker describe-model-package --model-package-name <arn> and check the model description or source tags.
- If neither is available, ask the user.
Does the user have an evaluation dataset? LLM-as-Judge requires one.

Custom Scorer validation

Does the user have an evaluation dataset? Custom Scorer requires one. (Works with both OSS and Nova models, though for Nova only custom lambdas are supported.)

If validation fails, tell the user which requirement(s) aren't met and offer alternatives:

"[Evaluation type] won't work because [reason]."

If the failure reason was lack of an eval dataset, inform the user that this skill's evaluation workflows require one, but do not dead-end the conversation.

If the failure reason is something else, offer to help them pick a different evaluation type.

⏸ Wait for user.

If they say they do want help choosing a different eval type → read references/evaluation-type-guide.md.

If validation passes, read the corresponding reference file:

User chose	Read
LLM-as-Judge	`references/llmaaj-evaluation.md`
Custom Scorer	`references/custom-scorer-evaluation.md`

Follow the reference file's instructions from the beginning.
