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 B, and why

obsidian-mobile-sync scanned grade B with 2 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Obsidian Mobile Sync

Setup mobile access to Obsidian vault via GitHub sync (free) or Obsidian Sync (paid).

CRITICAL Pitfall

"Obsidian doesn't need login" — WRONG for mobile sync.

  • Desktop-only: No account needed
  • Mobile sync: Requires authentication (Obsidian Sync OR Git sync)

Always clarify sync requirements when user asks about mobile access.

Sync Options

ALWAYS present free options FIRST. Users expect cost-free solutions by default.

Option 1: Git Sync (Free) ⭐ RECOMMENDED

Cost: $0 (100% free)
Setup: Push to GitHub → Install Obsidian Git plugin (desktop)
Mobile:

  • Android: MGit (free) — full Git functionality
  • iOS: Working Copy (free for pull, $19.99 for push) OR iSH + Git (free, terminal-based)

Pros: Free, version control, forever history, no vendor lock-in
Cons: Manual sync on mobile (2-3 taps per session)

iOS Free Alternative: iSH app + Git CLI (100% free, no purchase needed)

Option 2: Obsidian Sync (Paid)

Cost: $10/month or $96/year
Setup: Create account → Subscribe → Enable sync
Mobile: Install app → Sign in → Select vault
Pros: Auto-sync, conflict resolution, E2E encrypted, zero manual work
Cons: Paid subscription ($120/year)

When to recommend: User explicitly values convenience over cost, or has budget for premium tools.

Install:

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list
sudo apt update && sudo apt install gh -y

Login:

gh auth login
# Select: GitHub.com → HTTPS → Yes → Login with browser

Scope Management: gh auth login grants basic scopes (repo, workflow, read:org). If you need to delete repos later, add delete_repo scope:

gh auth refresh -h github.com -s delete_repo

This prevents "HTTP 403: needs delete_repo scope" errors when running gh repo delete.

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.
