Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.01237 |
| Opus 5 | $0.00011 | $0.00619 |
| Sonnet 5 | $0.00004 | $0.00247 |
| Haiku 4.5 | $0.00002 | $0.00124 |
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 4d 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.
This is a copy
100% identical to obsidian — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 97 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/.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.
Search
Use search_files for both filename and content searches. Prefer this over grep, find, or ls.
- For filenames, use
search_fileswithtarget: "files"and a filenamepattern. - For note contents, use
search_fileswithtarget: "content", the content regex aspattern, andfile_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:
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.

obsidian is a skill published in the GitHub repository AtlasOmnia/hermes-custom-pack (56 stars, last pushed 24d ago), licensed MIT. It adds 22 tokens to every session and 1,237 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to obsidian, differing in 0 lines, and is treated as a copy.
