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-vault 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 7d 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.

What it actually says

Obsidian Vault

Vault location

/mnt/d/Obsidian Vault/AI Research/

Mostly flat at root level.

Naming conventions

  • Index notes: aggregate related topics (e.g., Ralph Wiggum Index.md, Skills Index.md, RAG Index.md)
  • Title case for all note names
  • No folders for organization - use links and index notes instead

Linking

  • Use Obsidian [[wikilinks]] syntax: [[Note Title]]
  • Notes link to dependencies/related notes at the bottom
  • Index notes are just lists of [[wikilinks]]

Workflows

Search for notes

# Search by filename
find "/mnt/d/Obsidian Vault/AI Research/" -name "*.md" | grep -i "keyword"

# Search by content
grep -rl "keyword" "/mnt/d/Obsidian Vault/AI Research/" --include="*.md"

Or use Grep/Glob tools directly on the vault path.

Create a new note

  1. Use Title Case for filename
  2. Write content as a unit of learning (per vault rules)
  3. Add [[wikilinks]] to related notes at the bottom
  4. If part of a numbered sequence, use the hierarchical numbering scheme

Find related notes

Search for [[Note Title]] across the vault to find backlinks:

grep -rl "\\[\\[Note Title\\]\\]" "/mnt/d/Obsidian Vault/AI Research/"

Find index notes

find "/mnt/d/Obsidian Vault/AI Research/" -name "*Index*"

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.
