Overview

SierraVault is a comprehensive Obsidian-based wiki documenting Sierra On-Line’s complete gaming history — from the earliest Hi-Res Adventures in 1980 through modern fan remakes and spiritual successors from Sierra alumni.

What started as a personal Obsidian vault turned into a full research project with a custom toolchain for crawling sources, generating content, and enforcing quality standards. Every page is backed by 15–40 citations from original sources: interviews, magazine reviews, postmortems, and developer commentary.

Guides & Reference

Beyond individual game pages, the vault includes curated guides:

  • Playing Sierra Games Today — modern compatibility and setup
  • Buying Guide — where to legally purchase classics
  • Parser Commands — comprehensive verb reference for parser-era games
  • Sierra Deaths — the infamous death catalog
  • Easter Eggs and Secrets — hidden content across the catalog

  • Protagonist Guide — every playable character across the library
  • Cancelled Games — projects that never shipped
  • Engine Index — AGI, SCI, and everything in between

Content Pipeline

The project uses a custom Python toolchain (58 scripts) to research, generate, and validate content:

Discovery → Crawling → Enrichment → Generation → Scoring → Review → Publish
  • Discovery — Brave Search, MobyGames API to find sources for each game
  • Crawling — ScraperAPI and custom scrapers to extract content
  • Enrichment — Cross-reference and verify across multiple AI models
  • Generation — Claude Opus drafts comprehensive pages from research
  • Scoring — Dual-model quality check (Claude + GPT, both must pass 90%)
  • Review — Human editorial approval before publishing
  • Validation — Link checking, reference deduplication, frontmatter standardization

Scripts include specialized tools like hallucination detection, orphan page discovery, parallel enrichment, and automated series navigation generation.

Quality Standards

  • 15+ citations per page — every claim backed by sources
  • No duplicate URLs — each source used once
  • Structural score 90%+ — follows template format
  • LLM score 90%+ — accuracy verified by Claude + GPT
  • 95%+ for flagships — higher bar for major series entries
