# Obsidian Wiki — Copilot Context

This project is a **skill-based framework** for building and maintaining an Obsidian knowledge base using AI coding agents. There are no scripts or dependencies — everything is markdown instructions that the agent executes directly.

## Project Overview

- **Purpose:** Build and maintain an Obsidian wiki using the LLM Wiki pattern (Andrej Karpathy).
- **Tech Stack:** Markdown only. No code, no dependencies. The AI agent IS the runtime.
- **Key Config:** `.env` contains `OBSIDIAN_VAULT_PATH` pointing to the vault location.
- **Skills:** `.skills/` contains skill folders, each with a `SKILL.md` defining a workflow.

## Key Concepts

- The wiki is a **compiled artifact** — knowledge distilled from raw sources into interconnected pages.
- Every wiki page has YAML frontmatter: `title`, `category`, `tags`, `sources`, `created`, `updated`.
- Pages are connected with Obsidian `[[wikilinks]]`.
- A `.manifest.json` in the vault root tracks all ingested sources for delta-based updates.
- `index.md` and `log.md` must be updated after every operation.

## Coding Conventions

- When creating wiki pages, always use YAML frontmatter.
- Use `[[wikilinks]]` syntax for cross-references — NOT markdown links.
- Project-specific knowledge goes in `projects/<name>/`. Global knowledge goes in top-level categories.
- Never modify the `.obsidian/` directory.
