These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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 11d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Obsidian

Obsidian vaults are normal folders on disk. Notes are usually *.md. Do not touch .obsidian/, *.canvas files, or plugin data unless the user explicitly asks.

Typical Vault Structure

  • notes: *.md
  • config: .obsidian/
  • canvases: *.canvas
  • attachments: images, PDFs, and other files in normal folders

Vault Location

Resolve the vault path first. Use this order:

  1. user-provided vault path
  2. remembered vault path from MEMORY.md
  3. OBSIDIAN_VAULT_PATH
  4. obsidian-cli print-default --path-only
  5. macOS config: ~/Library/Application Support/obsidian/obsidian.json Use the vault with "open": true.
  6. common defaults:
    • ~/Documents/Obsidian Vault
    • ~/Documents/Obsidian
    • ~/Library/Mobile Documents/iCloud~md~obsidian/Documents

Do not treat the current workspace as the vault unless the user explicitly says so, the workspace contains .obsidian/, or Obsidian's config points there.

If the resolved vault came from steps 3-6, tell the user which path you found and ask for confirmation before making write changes. For read-only discovery or search, you may proceed, but note the source of the vault path.

If you find a stable, unambiguous vault path, save a short fact to MEMORY.md, for example Obsidian vault: /absolute/path/to/vault. Do not save ambiguous or temporary vaults.

Quick Start

Assume:

VAULT="/absolute/path/to/vault"

Prefer obsidian-cli when available for vault-aware search and safe moves. Otherwise use the shell commands below.

Pick default vault:

obsidian-cli print-default --path-only
printenv OBSIDIAN_VAULT_PATH
cat "$HOME/Library/Application Support/obsidian/obsidian.json"
  • Read: sed -n '1,220p' "$VAULT/Folder/Note.md" This is a bounded first read. If the note is longer than 220 lines, say so and continue with a wider or full read instead of pretending you saw the whole file.
  • List: rg --files "$VAULT" -g '*.md'
  • Search: obsidian-cli search "keyword" obsidian-cli search-content "keyword" Shell fallback: rg --files "$VAULT" -g '*.md' | rg -i 'keyword' rg -n --glob '*.md' 'keyword' "$VAULT"
  • Create: obsidian-cli create "Folder/New note" --content "# Title" Shell fallback: set -C && printf '# Title\n' > "$VAULT/Folder/New note.md"; set +C
  • Append: printf '\nNew content\n' >> "$VAULT/Folder/Existing note.md"
  • Move / rename: obsidian-cli move "Old Path/Note" "New Path/Note" Shell fallback: mv -n "$VAULT/Old Path/Note.md" "$VAULT/New Path/Note.md" If you move manually, search for and fix stale links before finishing.
  • Delete: obsidian-cli delete "Path/Note" Shell fallback: rm "$VAULT/Path/Note.md"

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.
