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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00017 | $0.00382 |
| Opus 5 | $0.00009 | $0.00191 |
| Sonnet 5 | $0.00003 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
obsidian scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
88% identical to obsidian — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Obsidian Vault
Location: Set via OBSIDIAN_VAULT_PATH environment variable (e.g. in ~/.hermes/.env).
If unset, defaults to ~/Documents/Obsidian Vault.
Note: Vault paths may contain spaces - always quote them.
Read a note
VAULT="${OBSIDIAN_VAULT_PATH:-$HOME/Documents/Obsidian Vault}"
cat "$VAULT/Note Name.md"
List notes
VAULT="${OBSIDIAN_VAULT_PATH:-$HOME/Documents/Obsidian Vault}"
# All notes
find "$VAULT" -name "*.md" -type f
# In a specific folder
ls "$VAULT/Subfolder/"

Wikilinks
Obsidian links notes with [[Note Name]] syntax. When creating notes, use these to link related content.
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.
