gas-fakes: Skill for Claude Code

.agents/skills/gassypedia-database/SKILL.md

gassypedia-database is a skill for Claude Code, Codex from brucemcpherson/gas-fakes. It costs 55 tokens per session (2,247 once invoked), scanned A, original, MIT.

A reference for querying the Gassypedia BigQuery dataset, which contains analyzed Google Apps Script projects and related repository, file, owner, and time-snapshot data.

In plain words
What is it for?
Use it to explore Google Apps Script projects, write BigQuery queries, or create tests for questions about repositories, files, owners, and libraries.
Why use it?
It helps turn plain-language questions into SQL that uses the dataset's structure correctly instead of guessing table relationships.

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

gassypedia-database 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 10d 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.

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.

📚 Gassypedia Database Skill Reference

The gassypedia-database skill provides complete context, schema definitions, and query patterns to translate natural language requests into efficient BigQuery SQL.

🌐 Overview: What is Gassypedia?

The Gassypedia dataset is a comprehensive analytical snapshot of Google Apps Script (GAS) projects. It aggregates metadata from various sources, primarily GitHub repositories, to provide deep insights into how GAS projects are developed, hosted, and utilized.

The data tracks:

  • Repositories (repos): The GitHub hosts for the GAS projects.
  • Files (files): Individual script files within those repositories.
  • Owners (owners): The GitHub users who own the repositories.
  • Loads (loads): Temporal snapshots of the entire dataset, allowing for time-series analysis.

The core of this skill is the big_join view, which performs complex joins across these underlying tables to create a single, highly denormalized record for every analyzed file, enriched with metadata from its owner, repository, and associated libraries.

🛠️ Core Schema: scrmin.gassypedia.big_join

The big_join view is the primary target for all analytical queries. It is a complex view designed to flatten the relationships between files, repositories, and owners into a single, powerful record.

📊 View Structure Definition

Field Name Type Description
loadDate DATE The date of the data snapshot (when the data was loaded).
libraryInfo STRUCT Metadata identifying the script acting as a library.
ownerId INT64 The ID of the primary owner of the repository.
ownerIsHireable BOOL Flag indicating if the owner is marked as hireable on GitHub.
repoInfo STRUCT Detailed metadata about the repository itself.
isAddon BOOL True if the file content indicates it is a Google Workspace Add-on.
file STRUCT The raw metadata of the file itself (e.g., name, size, path).
ownerInfo STRUCT Detailed profile information about the repository owner.
addOnInfo STRUCT Structured metadata extracted from the file's Add-on configuration (if applicable).

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.
