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 6d 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 Skill

Create, edit, search, and manage Obsidian vault files using the Obsidian CLI (90+ commands) and direct file operations with full knowledge of Obsidian-specific syntax extensions.

Based on kepano/obsidian-skills by Steph Ango (MIT License).

Obsidian CLI

The Obsidian CLI (requires Obsidian 1.12.7+) provides native access to vault operations. Prefer CLI commands over raw file reads for searching, querying, and metadata operations.

See reference/ObsidianCLI.md for the full command reference.

Prerequisites

  • Obsidian desktop app must be running (CLI communicates with the app)
  • Enable via: Settings > General > "Command line interface"
  • Linux: binary at ~/.local/bin/obsidian

When to Use CLI vs Direct File Operations

Task Use Why
Search notes CLI: obsidian search query="..." Native full-text + metadata search
Read a note CLI: obsidian read path="note.md" Simpler than resolving vault paths
Create a note CLI: obsidian create path="note.md" content="..." Handles templates, dedup
Append to daily note CLI: obsidian daily:append content="..." Auto-resolves daily note path
Get/set properties CLI: obsidian property:set/read No YAML parsing needed
Find backlinks CLI: obsidian backlinks path="note.md" Graph traversal
Find orphan notes CLI: obsidian orphans No equivalent via file ops
Query a Base CLI: obsidian base:query path="db.base" Native query engine
Toggle tasks CLI: obsidian task path="note.md" line=5 Clean task management
Write complex Markdown Direct Write/Edit tool Full control over formatting
Create .base files Direct Write tool Full YAML control needed
Create .canvas files Direct Write tool Full JSON control needed
Bulk file operations Direct file tools CLI is per-file

What ships with it

4 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.
