One thing to look at

  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

SKILL.md

1.1 KB, 267 tokens by cl100k_base, as published. Nobody here has run it

When to invoke

  • You want a lightweight, fast static check on SQL before review.
  • You suspect performance issues from patterns like SELECT * or non-sargable filters.

Inputs needed

  • --sql_file: Path to a .sql file.
  • --out_json: Path to write findings as JSON.

Workflow

  1. Read SQL text.
  2. Run heuristic rule checks (regex-based):
    • SELECT *
    • WHERE clause using functions on indexed-looking columns (e.g., LOWER(col)=...)
    • Leading wildcard LIKE '%foo'
    • OR chains on same column
    • Implicit joins via comma in FROM a, b
    • NOT IN (subquery) null-trap risk
    • Missing WHERE on UPDATE/DELETE
  3. Emit findings with rule id, severity, message, and line number when detectable.

Output format

JSON with:

  • file
  • findings[]: {rule_id, severity, message, line}

Guardrails

  • Not a full SQL parser; results are best-effort.
  • Do not auto-rewrite queries without human review.

Reference code

  • sql_anti_pattern_linter.py
