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

Obsidian Vault

Use this skill for filesystem-first Obsidian vault work: reading notes, listing notes, searching note files, creating notes, appending content, and adding wikilinks.

Vault path

Use a known or resolved vault path before calling file tools.

The documented vault-path convention is the OBSIDIAN_VAULT_PATH environment variable, for example from ${HERMES_HOME:-~/.hermes}/.env. If it is unset, use ~/Documents/Obsidian Vault.

File tools do not expand shell variables. Do not pass paths containing $OBSIDIAN_VAULT_PATH to read_file, write_file, patch, or search_files; resolve the vault path first and pass a concrete absolute path. Vault paths may contain spaces, which is another reason to prefer file tools over shell commands.

If the vault path is unknown, terminal is acceptable for resolving OBSIDIAN_VAULT_PATH or checking whether the fallback path exists. Once the path is known, switch back to file tools.

Read a note

Use read_file with the resolved absolute path to the note. Prefer this over cat because it provides line numbers and pagination.

List notes

Use search_files with target: "files" and the resolved vault path. Prefer this over find or ls.

  • To list all markdown notes, use pattern: "*.md" under the vault path.
  • To list a subfolder, search under that subfolder's absolute path.

Use search_files for both filename and content searches. Prefer this over grep, find, or ls.

  • For filenames, use search_files with target: "files" and a filename pattern.
  • For note contents, use search_files with target: "content", the content regex as pattern, and file_glob: "*.md" when you want to restrict matches to markdown notes.

Create a note

Use write_file with the resolved absolute path and the full markdown content. Prefer this over shell heredocs or echo because it avoids shell quoting issues and returns structured results.

Append to a note

Prefer a native file-tool workflow when it is not awkward:

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.
