finding-data-lake-assets

finding-data-lake-assets is a skill for Claude Code from aws/agent-toolkit-for-aws. It costs 116 tokens per session (4,175 once invoked), scanned B, original, Apache-2.0.

A resolver for finding data-lake assets across Glue, S3, S3 Tables, and Redshift. It turns a name, keyword, column, or path into the specific table or dataset it refers to.

In plain words
What is it for?
Use it to locate tables, datasets, columns, S3 paths, lakehouse assets, and matching warehouse records.
Why use it?
It saves time when you know what the data should contain but not where it is stored or which catalog entry is correct.

About the project

Agent Toolkit for AWS is a collection of AWS-supported MCP servers, skills, plugins, commands, and hooks that help AI coding agents build, deploy, and manage applications on AWS. It is used by developers working with AWS services through agents such as Claude Code, Codex, Cursor, and Kiro. The catalogue entries are the toolkit's own agent extensions for AWS development and operations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

finding-data-lake-assets scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Instruction-override phrasingmediumPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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, NOT the legacy glue search-tables used in Step 5. They are experimental — not available in every CLI build. Gate the lookup on two checks first:
