obsidian

obsidian is a skill for Claude Code from sidedwards/obsidian-claude-plugin. It costs 60 tokens per session (2,220 once invoked), scanned A, original, MIT.

A command-line connection to Obsidian, an app for storing linked notes in a personal knowledge vault. It can read, create, search, and manage vault content through terminal commands, when Obsidian 1.12 or newer is running with its command-line interface enabled.

In plain words
What is it for?
Use it to manage notes, folders, tags, tasks, properties, plugins, synchronization, and publishing in an Obsidian vault.
Why use it?
It lets a coding agent work with notes and tasks from the terminal instead of switching to the Obsidian app for every operation.

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 5d 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 — 272 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Obsidian CLI

Control Obsidian from the terminal. Requires Obsidian 1.12+ running with CLI enabled.

Quick Usage

Single command: obsidian <command> [params] [flags] Interactive TUI: obsidian (then type commands interactively)

Syntax Rules

  • Parameters take values: parameter=value or parameter="value with spaces"
  • Flags are boolean switches: silent, overwrite, total
  • Newlines in content: use \n for newlines, \t for tabs
  • Vault targeting: vault=<name> (defaults to current working directory vault)
  • File targeting: file=<name> (wikilink resolution) or path=<path> (exact path)
  • Copy output: append --copy to any command

What ships with it

1 file 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.
