## What it does

This skill resolves references to data lake and lakehouse assets in AWS Glue Data Catalog, S3, S3 Tables, and Redshift. It takes a single input: a table name, keyword, column name, or an `s3://` path. The skill focuses strictly on locating assets. It does not run SQL queries or create tables, leaving those jobs to `querying-data-lake` and `creating-data-lake-table`.

For command execution, the agent defaults to AWS MCP server tools (`aws___call_aws`) and falls back to the AWS CLI if MCP is missing. It verifies credentials with `aws sts get-caller-identity` before running any search. The agent also asks for the target AWS region if it is not set.

If supported by the local CLI version, the skill can check experimental Glue Discovery APIs like `search-assets` and `get-asset`. It asks for user confirmation before calling them. Without valid AWS credentials and a configured region, searches fail immediately.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws finding-data-lake-assets
```

2. **Manually: put the files in place**
- File: `.github/skills/finding-data-lake-assets/SKILL.md`

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill finding-data-lake-assets -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/finding-data-lake-assets/SKILL.md

## When to use it
- locate AWS Glue tables by column name
- resolve a dataset catalog entry from an S3 path
- find Redshift and S3 Tables assets by keyword
- inspect asset schema metadata through Glue Discovery

## Example prompts
- Find the Glue Data Catalog table that contains column user_id
- Where is our data for path s3://my-company-analytics/raw-events/?
- Locate Redshift table for keyword payments

# Find Data Lake Assets

## Overview

Resolves data lake asset references to concrete catalog entries. Acts as a
resolver for other skills and direct user requests. Covers Glue,
S3, S3 Tables, and Redshift. Optimized for low token usage — return the
answer fast and get out of the way.

**Constraints for parameter acquisition:**

- You MUST accept a single argument: table name, keyword, column name, or S3 path
- You MUST accept the argument as direct input or a pointer to a file containing the spec
- You MUST ask for the target AWS region if not already set
- You MUST confirm ambiguous input before searching (e.g., "Did you mean table X or bucket Y?")
- You MUST respect the user's decision to abort at any step

## Common Tasks

You MUST execute commands using AWS MCP server tools when connected — they
provide validation, sandboxed execution, and audit logging. Fall back to
AWS CLI only if MCP is unavailable. You MUST explain each step before
executing.

### 1. Verify Dependencies

Check for required tools and AWS access before searching.

**Constraints:**

- You MUST verify AWS MCP server tools (`aws___call_aws`) are available; fall back to AWS CLI if not
- You MUST confirm credentials with `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)

The customer may publish **context skill assets** in the Glue Data Catalog that map
their business language to the real tables — canonical names and aliases, join keys,
metrics, usage notes, descriptions — that the raw schema does not carry. When present,
this catalog is often enough to answer the request on its own.

These are the **Glue Discovery** operations (`SearchAssets` / `GetAsset` /
`ListIterableForms` / `BatchGetIterableForms`) — a distinct metadata-search surface,
```
