## What it does

The Python helpers `scripts/check_role.py` and `scripts/create_role.py` verify that an AWS account has a valid SageMaker execution role. The skill scans for roles matching common name patterns, ranks them by last-used date, and verifies that `sagemaker.amazonaws.com` can assume the role. If no role was used recently, it falls back to the newest creation date.

Role creation runs only when discovery returns nothing and the caller holds IAM write permissions. Attempting to call `iam:CreateRole` from an SSO session without write access fails immediately. This skill interrupts execution early and reports the exact permissions needed.

Run the scripts directly in PowerShell or your native shell where `aws sts get-caller-identity` works. Shims like WSL or Git Bash on Windows often fail because they do not inherit the host SSO session or credential chain.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add huggingface/skills --skill hf-cloud-sagemaker-iam-preflight -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/hf-cloud-sagemaker-iam-preflight/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/hf-cloud-sagemaker-iam-preflight/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add huggingface/skills --skill hf-cloud-sagemaker-iam-preflight -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/hf-cloud-sagemaker-iam-preflight/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add huggingface/skills --skill hf-cloud-sagemaker-iam-preflight -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/hf-cloud-sagemaker-iam-preflight/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install huggingface/skills hf-cloud-sagemaker-iam-preflight
```

2. **Manually: put the files in place**
- File: `.github/skills/hf-cloud-sagemaker-iam-preflight/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add huggingface/skills --skill hf-cloud-sagemaker-iam-preflight -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/huggingface/skills --path skills/hf-cloud-sagemaker-iam-preflight
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/hf-cloud-sagemaker-iam-preflight/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add huggingface/skills --skill hf-cloud-sagemaker-iam-preflight -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/huggingface/skills/tree/HEAD/skills/hf-cloud-sagemaker-iam-preflight/SKILL.md

## When to use it
- discover an existing SageMaker execution role before model deployment
- validate trust policies for sagemaker.amazonaws.com
- create an execution role scoped to a specific S3 model bucket
- prevent deployment failures caused by SSO IAM restrictions

## Example prompts
- Check if there is a usable SageMaker execution role in this AWS account
- Validate IAM role my-custom-sagemaker-role before deploying the endpoint
- Create a minimal SageMaker execution role for bucket my-model-artifacts

name: hf-cloud-sagemaker-iam-preflight
description: 'Ensure a usable SageMaker execution role exists before deploying or training. Use this skill whenever about to create a SageMaker endpoint, model, training job, or any resource that requires an execution role. Use it especially when the user has not provided a role ARN explicitly, when scripts are about to call `iam:CreateRole`, or when an AccessDenied error mentions an IAM action. Never blindly call `iam:CreateRole` — always check for existing roles first. This skill prevents the most common SageMaker deployment failure: trying to create IAM resources from an SSO principal that has no IAM write permissions.'

# SageMaker IAM Preflight

Every SageMaker resource needs an **execution role** — the IAM role SageMaker assumes to read model artifacts from S3, pull serving containers from ECR, and write logs. Most deployments fail here because the script tried to create a new role without checking if a usable one already existed, then blew up because the caller is an SSO principal.

This skill encodes the right order: discover, validate, only create if necessary.

## Running the helpers (cross-platform)

The helpers are Python so they run identically on Windows, macOS, and Linux:

```bash
python3 scripts/check_role.py        # macOS / Linux
python  scripts/check_role.py        # Windows (PowerShell / cmd)
```

**Run them from the shell where the AWS CLI already works** — i.e. wherever `aws sts get-caller-identity` succeeds. The script shells out to that same `aws` binary and inherits the shell's profile, region, SSO session, proxy, and credential chain.

> **Windows / WSL / Git Bash caveat.** Do **not** invoke these through a Bash shim (WSL, Git Bash, MSYS) on Windows. Those Bash environments frequently do **not** share the Windows AWS config, credentials, SSO sessions, environment variables, or proxy settings — so `aws sts get-caller-identity` fails inside Bash even when it works natively in PowerShell. (This is exactly why the old `.sh` helpers failed on Windows and were replaced with Python.) If you're in PowerShell, run `python ...\check_role.py` directly in PowerShell. If the helper still can't see your identity, run the same discovery natively (see "Native AWS CLI equivalent" below) in the shell where `aws sts get-caller-identity` returns your ARN.

## Order of operations

### Step 1 — Did the user provide a role?

Validate that one specifically:

```bash
python3 scripts/check_role.py "<role-name-or-arn>"
```
