claude-obsidian is a local knowledge system that turns source material into linked, source-cited Markdown notes in an Obsidian vault for use with Claude Code and compatible agent hosts. People use it to capture research, retrieve evidence-grounded answers, maintain knowledge, and map connections while retaining ownership of their files. The catalogue entries provide workflows and extensions for operating this knowledge system.

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 | $0.00219 | $0.00219 |
| Opus 5.5 | $0.00088 | $0.00088 |
| Sonnet 5.5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
claude-obsidian GEMINI.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 1mo 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.
What it actually says
claude-obsidian: Gemini instructions
Read AGENTS.md as the canonical host-neutral contract. Skills live in
skills/<name>/SKILL.md and the portable core lives in claude_obsidian/.
Install skill discovery with:
bash scripts/setup-multi-agent.sh --host gemini
bash scripts/setup-multi-agent.sh --host gemini --apply
The first command previews the links; the second applies that reviewed scope.
This repository is product source, not the default user vault. Create a
separate vault with the dry-run-first init command or adopt an existing vault.
Resolve that vault before reading wiki/hot.md or running a skill.
All shared mutations use one inspected claude-obsidian.transaction.v1 bundle.
Parallel workers draft only. Do not use direct shared writes, automatic commits,
or the deprecated per-file lock helper. Remote egress and destructive actions
need explicit user consent.

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.
