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-markdown 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 11d 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 Markdown Skill

Use this skill when creating or editing .md files in the vault.

Rules:

  • Use YAML frontmatter for durable wiki pages.
  • Use [[wikilinks]] for internal links.
  • Use path-based wikilinks when clarity matters, such as [[concepts/example-concept]].
  • Use Markdown links for external URLs.
  • Use source_paths only for raw files that actually exist.
  • Keep pages focused and graph-friendly.

Common frontmatter:

---
title: Human Readable Title
tags:
  - concept
created: YYYY-MM-DD
updated: YYYY-MM-DD
source_paths:
  - raw/path/to/source.md
status: active

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.
