What is claude-obsidian-assistant CLAUDE.md?

Project instructions for an assistant that works with Claude Code and Obsidian, an app for keeping notes in a linked vault of files. They explain the vault structure, important files, and Obsidian’s file format.

Navigating the vault, reading the required project files, and creating or editing Obsidian notes in the expected format.

They help an agent find the right notes and follow the project’s organization instead of treating the vault as an undifferentiated folder.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01063	$0.01063
Opus 5.5	$0.00425	$0.00425
Sonnet 5.5	$0.00213	$0.00213
Haiku 4.5	$0.00106	$0.00106

Security

Grade A, and why

claude-obsidian-assistant CLAUDE.md 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 2mo 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.

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.
