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.

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 | $0.00068 | $0.01137 |
| Opus 5.5 | $0.00027 | $0.00455 |
| Sonnet 5.5 | $0.00014 | $0.00227 |
| Haiku 4.5 | $0.00007 | $0.00114 |
Grade A, and why
obsidian-markdown scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian Flavored Markdown
Use this as a compact fallback for Obsidian-specific syntax. Prefer a separately
installed kepano/obsidian-skills obsidian-markdown skill when available,
then current Obsidian Help, for detailed or
version-sensitive questions.
Resolve the installed product root from this skill's own location, not from the vault or current working directory:
PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
CORE="$PRODUCT_ROOT/scripts/claude-obsidian.py"
test -f "$CORE"
Every ../wiki/references/ link in this file resolves the same way, relative
to this skill's own directory under $PRODUCT_ROOT, never relative to the
selected vault's wiki/ directory.
Answer syntax questions read-only. If the user requests a vault edit, draft the
complete note, read operation-transactions.md,
and build one claude-obsidian.transaction.v1 bundle with
operation_type: markdown and only wiki/ targets. Inspect it, then set
APPROVAL_SHA256 to the returned approval_sha256 after review and apply it
through the same vault-bound plan. A canonical page create or removal includes
an active index or MOC update in that bundle; update the overview only when its
stable high-level synthesis changed:
python3 "$CORE" transaction inspect "$BUNDLE" --vault "$VAULT"
python3 "$CORE" transaction apply "$BUNDLE" --vault "$VAULT" \
--approved-plan-sha256 "$APPROVAL_SHA256"
Never write a note directly.
Properties
Use flat YAML properties and YYYY-MM-DD dates. Quote wikilinks inside YAML.

Do not nest objects in generated wiki properties. Use block lists rather than
inline YAML arrays. A numeric-only tag is invalid in Obsidian even when quoted as a YAML string.
Use year/2026 or y2026, or store a number in a year property. Tags need
at least one non-numeric character; valid Unicode tags remain supported. See
Tags, checked 2026-10-17. Keep unknown existing
properties unless the requested edit changes them.
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-markdown is a skill published in the GitHub repository AgriciDaniel/claude-obsidian (15,791 stars, last pushed 2d ago), licensed MIT. It adds 68 tokens to every session and 1,137 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
