obsidian

obsidian is a skill for Claude Code, Codex from Threat-Vector-Security/guardian-agent. It costs 0 tokens per session (525 once invoked), scanned A, original, Apache-2.0.

A skill for working with Obsidian vaults, which are ordinary folders containing Markdown notes and related files. It can locate the active vault from Obsidian’s settings.

In plain words
What is it for?
Finding and editing Obsidian notes, handling vault files, and following Obsidian-specific workflows.
Why use it?
It prevents scripts from guessing which notes folder to use, especially when several vaults exist.

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 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.

How it starts

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Obsidian

Obsidian vault = a normal folder on disk.

Use this only for explicit Obsidian vault workflows. For generic local docs, repo docs, or indexed knowledge lookup, prefer knowledge-search.

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.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

obsidian is a skill published in the GitHub repository Threat-Vector-Security/guardian-agent (11 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 525 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
