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.
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 | $0.00186 | $0.00186 |
| Opus 5 | $0.00093 | $0.00093 |
| Sonnet 5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
claude-obsidian copilot-instructions.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 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.
What it actually says
claude-obsidian Copilot instructions
Read AGENTS.md before proposing changes. The repository is an Agent Skills
package, Claude Code adapter, standard-library Python core, and deterministic
vault template—not the default live user vault.
When editing:
- Keep skill frontmatter to exactly
nameand single-linedescription. - Use Obsidian Flavored Markdown, flat YAML properties, and
YYYY-MM-DDdates. - Never modify existing raw source payloads.
- Route all logical knowledge mutations through one inspected operation bundle.
- Keep workers draft-only and lint/query read-only.
- Preserve vault path containment and product/vault separation.
- Add hermetic regression tests for behavior changes and run
make test. - Do not add secrets, private paths, unsupported capability claims, or duplicate command wrappers.

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.

claude-obsidian copilot-instructions.md is an instructions file published in the GitHub repository AgriciDaniel/claude-obsidian (14,662 stars, last pushed 10d ago), licensed MIT. It adds 186 tokens to every session, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings.
