sql-reporting

A set of rules and review steps for writing analytics SQL, the language used to query data warehouses and build reports.

In plain words
What is it for?
Use it when querying warehouse tables, combining data, counting or summing rows, or producing metrics for reports and dashboards.
Why use it?
It helps prevent expensive or overly broad queries and makes report SQL easier to check for correctness and consistency.

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 A, and why

sql-reporting scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

SQL Reporting Skill

Apply this skill before writing or running any analytics SQL so reports stay consistent and safe.

When to Use This Skill

Use this skill when the task involves:

  • Querying warehouse tables for a metric, report, or dashboard figure
  • Aggregating rows (counts, sums, rolling windows)
  • Cross-referencing two or more tables

Conventions

  1. Always SELECT explicit column names, never SELECT *.
  2. Filter on a partition/date column first to bound the scan.
  3. Alias aggregates with snake_case names (order_count, not count(*)).
  4. Cap exploratory queries with LIMIT unless an aggregate already collapses the result set.
  5. Prefer COUNT(DISTINCT ...) over a sub-query when de-duplicating.

Review Checklist (run before returning an answer)

  • No SELECT *.
  • A date or partition predicate is present.
  • Every aggregate has an explicit alias.
  • The query reads only from tables the task actually needs.

Output Format

Return the final SQL in a fenced ```sql block, then one sentence describing what the query returns.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sql-reporting is a skill published in the GitHub repository apache/airflow (46,647 stars, last pushed yesterday), licensed Apache-2.0. It adds 34 tokens to every session and 316 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
