AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured framework for managing the Amazon SageMaker model lifecycle. It covers planning, dataset preparation, fine-tuning, model evaluation, and endpoint deployment. The skill assists users in navigating SageMaker-specific workflows, including selecting base models from catalogs, configuring training and processing jobs, and diagnosing endpoint health. It supports various fine-tuning techniques and deployment pathways, ensuring users follow validated procedures for their machine learning projects on AWS.

What it does

Guides users through the end-to-end lifecycle of SageMaker model customization.
Assists in selecting and evaluating base models from SageMaker JumpStart and public hubs.
Provides workflows for validating and transforming training and evaluation datasets.
Supports configuration of fine-tuning techniques like SFT, DPO, RLVR, and RLAIF.
Facilitates the deployment of models to SageMaker endpoints or Bedrock.
Diagnoses endpoint issues including latency, errors, and container logs.

When to use it

When planning a new model customization or deployment project on SageMaker.
When you need to validate or transform datasets for training or evaluation.
When selecting a base model or choosing a fine-tuning technique.
When you need to configure training, processing, or evaluation jobs.
When deploying a model to a SageMaker endpoint or troubleshooting an existing one.
When setting up or managing a SageMaker Managed MLflow environment.

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.

Training Job Troubleshooting

Collect evidence

Run aws sagemaker describe-training-job --training-job-name <name> --region <region>. If submission itself failed and no job exists, preserve the CreateTrainingJob exception, request ID, timestamp, region, and redacted request parameters; do not start with log lookup.
For an existing job, record TrainingJobStatus, SecondaryStatus, FailureReason, SecondaryStatusTransitions, ResourceConfig, AlgorithmSpecification, InputDataConfig, and RoleArn.
Find the job's streams with aws logs describe-log-streams --log-group-name /aws/sagemaker/TrainingJobs --log-stream-name-prefix <name> --region <region>.
Read only matching streams with aws logs filter-log-events --log-group-name /aws/sagemaker/TrainingJobs --log-stream-names <stream...> --region <region>.
For performance/OOM analysis, query the /aws/sagemaker/TrainingJobs namespace for the exact job start/end window and Host=<job-name>/algo-<index> dimension. Run the following read-only command for each relevant host and metric (CPUUtilization, MemoryUtilization, DiskUtilization, and, on GPU instances, GPUUtilization and GPUMemoryUtilization):
```
aws cloudwatch get-metric-statistics \
  --namespace /aws/sagemaker/TrainingJobs \
  --metric-name CPUUtilization \
  --dimensions Name=Host,Value=<job-name>/algo-1 \
  --start-time <job-start-utc> --end-time <job-end-utc> \
  --period 60 --statistics Average Maximum \
  --region <region>
```
Replace the metric name and algo-<index> for each container. Correlate peaks with status transitions and decisive log timestamps; do not infer utilization from logs alone.

Do not relaunch, stop, change quota, or modify IAM without explicit approval.

Classification

Signature/evidence	Category	Likely fix
`CreateTrainingJob` `ValidationException` or local SDK validation before an ARN exists	Submission/config	Correct the rejected field, image/algorithm, channel, or name; preserve request ID and do not search nonexistent job logs
`ResourceLimitExceeded`, quota value below requested count	Quota	Request quota or choose approved compute; do not silently downsize
`AccessDenied`, `iam:PassRole`, S3/ECR/KMS denial	IAM	Add the missing least-privilege action/resource or correct the execution role trust
Missing object, wrong channel/path, malformed records	Data	Correct S3 URI/channel/schema; keep data and job in the same region
`CUDA out of memory`, exit 137, memory metric saturation	OOM	Reduce batch/model footprint or use verified larger/distributed compute
`AlgorithmError`, image entrypoint/module/dependency failure, or nonzero user-code exit	Container/algorithm	Use `FailureReason` plus the first decisive container traceback; fix code/image/dependencies before resubmission
NaN/Inf loss or divergence without infrastructure errors	Training config	Validate data, learning rate, precision, and recipe overrides
Long `Pending`/capacity message with quota available	Capacity	Use an approved training plan/reservation or another verified instance type/region
Internal service error with healthy user code	Service	Capture request/job ARN and timestamps; retry only when documented as transient

Escalation

If no customer-actionable cause is found—or an internal service error remains after user configuration, IAM, quota, data, and container evidence are ruled out—draft, but do not submit, an AWS Support case containing:

account and Region
job name/ARN, or failed CreateTrainingJob request ID
UTC failure window and status transitions
sanitized FailureReason, AlgorithmError, and decisive log/metric evidence
SageMaker Python SDK version and image URI/digest
every read-only check performed plus an explicit Not checked list
requested help: identify the internal failure and confirm whether retry is safe

Ask the user to review the draft before submission.

Response format

Return:

job name/ARN (or create-request ID when no job exists), status, and relevant timeline
failure signature and root-cause category
evidence from FailureReason, one or two decisive log lines, and metrics if checked
concrete repair steps ordered by lowest risk
an explicit Not checked section
a support-case draft only when the escalation condition above is met

If evidence is insufficient, say so and identify the next read-only check rather than guessing.
