obsidian-wiki copilot-instructions.md

Project instructions for an Obsidian wiki built from Markdown files and AI skills. Obsidian is a note-taking app; here, the wiki is assembled into linked knowledge pages with metadata and a record of imported sources.

In plain words
What is it for?
Use them when creating or updating wiki pages, resolving the Obsidian vault location, managing skills, linking notes, or processing source changes.
Why use it?
They explain how the wiki stores configuration, pages, links, and source history. This helps an agent update the knowledge base without breaking its structure or losing track of imported material.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

obsidian-wiki copilot-instructions.md 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.

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: Resolve config via AGENTS.md: inline @name vault override first, then .env, then the global config (~/.config/obsidian-wiki/config, XDG-style; legacy ~/.obsidian-wiki/config still honored). The resolved config supplies OBSIDIAN_VAULT_PATH.
  • 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.

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.
