obsidian

A workflow for working with Obsidian vaults, which are ordinary folders containing Markdown notes and related files. It uses `obsidian-cli` to find vaults and automate note-related tasks.

In plain words
What is it for?
Finding the active Obsidian vault, reading or managing Markdown notes, and automating vault tasks.
Why use it?
It avoids guessing which vault contains the notes and provides a command-line way to work with them.

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 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 2d 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.

Origin

This is a copy

92% identical to obsidian — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Obsidian

Obsidian vault = a normal folder on disk.

Vault structure (typical)

  • Notes: *.md (plain text Markdown; edit with any editor)
  • Config: .obsidian/ (workspace + plugin settings; usually don’t touch from scripts)
  • Canvases: *.canvas (JSON)
  • Attachments: whatever folder you chose in Obsidian settings (images/PDFs/etc.)

Find the active vault(s)

Obsidian desktop tracks vaults here (source of truth):

  • ~/Library/Application Support/obsidian/obsidian.json

obsidian-cli resolves vaults from that file; vault name is typically the folder name (path suffix).

Fast “what vault is active / where are the notes?”

  • If you’ve already set a default: obsidian-cli print-default --path-only
  • Otherwise, read ~/Library/Application Support/obsidian/obsidian.json and use the vault entry with "open": true.

Notes

  • Multiple vaults common (iCloud vs ~/Documents, work/personal, etc.). Don’t guess; read config.
  • Avoid writing hardcoded vault paths into scripts; prefer reading the config or using print-default.

obsidian-cli quick start

Pick a default vault (once):

  • obsidian-cli set-default "<vault-folder-name>"
  • obsidian-cli print-default / obsidian-cli print-default --path-only

Search

  • obsidian-cli search "query" (note names)
  • obsidian-cli search-content "query" (inside notes; shows snippets + lines)

Create

  • obsidian-cli create "Folder/New note" --content "..." --open
  • Requires Obsidian URI handler (obsidian://…) working (Obsidian installed).
  • Avoid creating notes under “hidden” dot-folders (e.g. .something/...) via URI; Obsidian may refuse.

Move/rename (safe refactor)

  • obsidian-cli move "old/path/note" "new/path/note"
  • Updates [[wikilinks]] and common Markdown links across the vault (this is the main win vs mv).

Delete

  • obsidian-cli delete "path/note"

Prefer direct edits when appropriate: open the .md file and change it; Obsidian will pick it up.

Changes

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.
