Brain Wiki Schema

This document defines the three page types in the brain wiki. The LLM must follow this schema exactly when generating wiki pages.

Wikilink Format

All cross-references use [[slug|Display Text]].

Rules:

• slug = lowercase filename without .md, spaces → hyphens, strip all non-alphanumeric except hyphens
• The | separator is REQUIRED — never use [[Title]] without a slug
• Examples: [[domain-driven-design|Domain Driven Design]], [[ryan-singer|Ryan Singer]]
• Slugs must resolve to an existing file in the inventory, or a file you are creating in this response

Slug generation examples:

• "Domain Driven Design" → domain-driven-design
• "It's Complicated" → its-complicated
• "gRPC" → grpc
• "GPT-4o" → gpt-4o

Domains

Use one of: ai-llm, software-engineering, product-strategy, finance-markets, personal, consulting, climate, infrastructure, security

Source Pages — wiki/sources/.md

One page per ingested source. Books are NEVER split across multiple source pages — update the existing one.

Required frontmatter:

title: <exact title>
type: article | pdf | book | video | note | project
domain: <domain>
date_ingested: YYYY-MM-DD
last_updated: YYYY-MM-DD
aliases:
  - <exact title>

Body sections (in this order):

Summary

2–3 sentences. Core argument or finding.

Key Claims

Bulleted list. Paraphrase — no verbatim quotes or code.

Concepts Introduced or Reinforced

Wikilinks to wiki/concepts/ ONLY. One per line.

Entities Mentioned

Wikilinks to wiki/entities/ ONLY. One per line.

Open Questions Raised

Gaps or follow-up questions from this source.

For books only, also add:

Chapters

One bullet per chapter with 1–2 sentence summary.

One page per idea, framework, methodology, or pattern.

Required frontmatter:

aliases:
  - <exact title>

Non-Negotiable Rules

1. Output ONLY a valid JSON array — no markdown fences, no prose before or after
2. Each element: {"path": "wiki/<type>/<slug>.md", "content": "...full markdown..."}
3. Slugs are kebab-case: lowercase, spaces→hyphens, strip special characters
4. Every wikilink must be [[slug|Display Text]] — the pipe separator is required
5. Dates always YYYY-MM-DD
6. Never reproduce verbatim code — describe the pattern or technique
7. Section links must match their section type (Related Concepts → concepts/ only, etc.)
8. One source page per book — if inventory shows it exists, include it as an UPDATE
