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-cli 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 3d 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.

Obsidian CLI

Use the obsidian CLI to interact with a running Obsidian instance. Requires Obsidian to be open.

Command reference

Run obsidian help to see all available commands. This is always up to date. Full docs: https://help.obsidian.md/cli

Syntax

Parameters take a value with =. Quote values with spaces:

obsidian create name="My Note" content="Hello world"

Flags are boolean switches with no value:

obsidian create name="My Note" silent overwrite

For multiline content use \n for newline and \t for tab.

File targeting

Many commands accept file or path to target a file. Without either, the active file is used.

  • file=<name> — resolves like a wikilink (name only, no path or extension needed)
  • path=<path> — exact path from vault root, e.g. folder/note.md

Vault targeting

Commands target the most recently focused vault by default. Use vault=<name> as the first parameter to target a specific vault:

obsidian vault="My Vault" search query="test"

Common patterns

obsidian read file="My Note"
obsidian create name="New Note" content="# Hello" template="Template" silent
obsidian append file="My Note" content="New line"
obsidian search query="search term" limit=10
obsidian daily:read
obsidian daily:append content="- [ ] New task"
obsidian property:set name="status" value="done" file="My Note"
obsidian tasks daily todo
obsidian tags sort=count counts
obsidian backlinks file="My Note"

Use --copy on any command to copy output to clipboard. Use silent to prevent files from opening. Use total on list commands to get a count.

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.
