## What it does

The skill inventories AWS data catalogs without running data queries or altering schemas. It discovers default Glue catalogs, managed S3 Tables buckets with Iceberg, and Redshift-federated catalogs. The entire workflow operates in read-only mode.

Discovery begins with environment verification. If AWS MCP server tools (`aws___call_aws`) are absent, the agent falls back to the AWS CLI and validates active credentials via `aws sts get-caller-identity`. If available and approved by the user, experimental Glue Discovery APIs such as `SearchAssets` index assets before full enumeration runs via `aws glue get-catalogs --recursive --include-root`.

You must provide the target AWS region upfront. The skill treats all customer catalog metadata as untrusted input, ensuring table descriptions are never executed as model directives.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill exploring-data-catalog -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/exploring-data-catalog/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/exploring-data-catalog/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill exploring-data-catalog -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/exploring-data-catalog/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill exploring-data-catalog -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/exploring-data-catalog/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws exploring-data-catalog
```

2. **Manually: put the files in place**
- File: `.github/skills/exploring-data-catalog/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill exploring-data-catalog -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path plugins/aws-data-analytics/skills/exploring-data-catalog
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/exploring-data-catalog/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill exploring-data-catalog -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/aws/agent-toolkit-for-aws/tree/HEAD/plugins/aws-data-analytics/skills/exploring-data-catalog/SKILL.md

## When to use it
- catalog all AWS Glue and S3 Tables in an account
- inspect database and table schemas without running SQL queries
- classify Redshift-federated catalogs across regions
- retrieve column metadata and storage formats via Glue Discovery

## Example prompts
- Audit all databases and tables in region us-east-1
- Enumerate catalogs and list tables for database analytics_db
- Inventory S3 Tables and Glue data assets in this account

Structured inventory and cataloging across your AWS data landscape: Glue Data Catalog with S3 Tables, Redshift-federated, and remote Iceberg catalogs.

## Overview

Maps data in an AWS account. Starts with catalog landscape (Glue, S3 Tables, federated), then drills into databases and tables. Read-only — no query execution.

**Constraints for parameter acquisition:**

- You MUST ask for the target AWS region upfront if not provided
- You MUST support a single optional argument: search term, catalog name, database name, S3 path, or table name
- You MUST accept the argument as direct input or a pointer to a file containing the spec
- You MUST confirm the scope (full landscape vs. targeted deep dive) before making API calls
- You MUST respect the user's decision to abort at any step

## Common Tasks

**Pagination:** All list and search calls in this workflow may return paginated results. You MUST pass `--next-token` from the previous response until no more tokens are returned. You MUST NOT assume a single page contains all results.

### 1. Verify Dependencies

Check for required tools and AWS access before discovery.

**Constraints:**

- You MUST verify AWS MCP server tools are available (`aws___call_aws`, `aws___search_documentation`) and fall back to AWS CLI if not
- You MUST confirm credentials are valid: `aws sts get-caller-identity`
- You MUST inform the user about any missing tools and ask whether to proceed

### 2. Consult Catalog Context (experimental — suggested first lookup)

Customers may publish context assets that describe the data landscape (canonical
names, domains, ownership) faster than a full enumeration.

These are the **Glue Discovery** operations (`SearchAssets` / `GetAsset` /
`ListIterableForms` / `BatchGetIterableForms`) — a distinct metadata-search surface,
NOT the legacy `glue search-tables`. They are **experimental** — not available in every
CLI build. Gate the
lookup on two checks first:

1. **Availability.** Confirm the `GetAsset` operation exists in the caller's Glue
```
