querying-data-lake

Execute and manage Athena SQL queries across default and federated catalogs (Glue, S3 Tables, Redshift). Triggers on phrases like: query data, run SQL, athena query, analyze table, SQL query, workgroup status, profile table, query Redshift catalog, query S3 Tables. Do NOT use for finding specific data assets (use finding-data-lake-assets), full catalog audits (use exploring-data-catalog), importing data (use ingesting-into-data-lake).

Quality

Content

85%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is well-structured and actionable: a sequenced workflow with real validation and recovery loops, concrete tool calls, and clean progressive disclosure into two reference files. It is efficient though slightly redundant in places, and could include a few more copy-paste examples.

Suggestions

De-duplicate guidance between the Principles section and the per-task Constraints to tighten conciseness.

Add one or two more copy-paste-ready command examples (e.g., a workgroup-listing and a start-query-execution for a federated/S3 Tables catalog) to round out actionability.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence (no "what is Athena" preamble), with directive MUST/MUST NOT constraints and compact tables; minor redundancy between the Principles and Constraints sections keeps it just short of a 5.

4 / 5

Actionability

Provides an executable `aws___call_aws(...)` example, concrete catalog-addressing rules, a statement-classification table, and a troubleshooting table with fixes; profiling detail is delegated to a reference rather than inlined, leaving a small gap in copy-paste coverage.

4 / 5

Workflow Clarity

Seven sequenced Common Tasks with explicit validation checkpoints (verify dependencies, classify before execute, confirm output location) and a feedback loop (on failure, list workgroups and retry with user choice) match the clear-sequence-with-validation-and-recovery anchor.

5 / 5

Progressive Disclosure

SKILL.md is a concise overview with well-signaled, one-level-deep markdown links to real files (references/workgroup-selection.md, references/query-patterns.md) and an Additional Resources list, splitting detail appropriately.

Description

90%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: it states the capability concisely, provides comprehensive natural trigger phrases, and disambiguates from sibling skills via explicit negative boundary guidance. The only soft spot is specificity, where only two headline action verbs are used.

Suggestions

Expand the headline capability beyond "execute and manage" to name a few more concrete actions (e.g., "profile tables, classify statements, track cost and data scanned") to lift specificity.

DimensionReasoningScore

Specificity

"Execute and manage Athena SQL queries across default and federated catalogs" names the domain plus two concrete actions (execute, manage), but does not enumerate a broader set of distinct capabilities, matching the 1-2-concrete-actions anchor.

3 / 5

Completeness

Explicitly answers both what ("Execute and manage Athena SQL queries across default and federated catalogs") and when ("Triggers on phrases like: …") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Lists natural phrases users would actually say — "query data", "run SQL", "athena query", "analyze table", "workgroup status", "profile table" — with synonyms and catalog-specific variants, giving comprehensive coverage.

5 / 5

Distinctiveness Conflict Risk

Clear Athena-query niche with explicit "Do NOT use for … (use finding-data-lake-assets / exploring-data-latalog / ingesting-into-data-lake)" boundary guidance, minimizing conflict risk.
