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 | $0.00074 | $0.00667 |
| Opus 5.5 | $0.00030 | $0.00267 |
| Sonnet 5.5 | $0.00015 | $0.00133 |
| Haiku 4.5 | $0.00007 | $0.00067 |
Grade A, and why
wiki-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Obsidian CLI read transport
Use this skill only to detect transport and read or search a selected vault.
The official executable is obsidian; binary presence alone does not prove it
is usable.
Resolve the installed product root from this skill's own location, not from the vault or current working directory:
PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
DETECT_TRANSPORT="$PRODUCT_ROOT/scripts/detect-transport.sh"
test -f "$DETECT_TRANSPORT"
Every ../wiki/references/ link in this file resolves the same way, relative
to this skill's own directory under $PRODUCT_ROOT, never relative to the
selected vault's wiki/ directory.
Detect safely
Probe without persisting host state:
bash "$DETECT_TRANSPORT" --peek --vault "$VAULT"
Trust available.cli.usable, not merely present or exit status. A supported
CLI can still be unavailable because the Obsidian app is not running, command
line access is disabled, or its response is an error. Use filesystem reads as
the portable fallback.
Persist a refreshed .vault-meta/transport.json only when the user or setup
workflow asks for a transport snapshot:
bash "$DETECT_TRANSPORT" --force --vault "$VAULT"
That file is derived runtime configuration, not knowledge content. Preserve a
valid manual_override recorded by the detector.
Read and search
Run official CLI commands from the selected vault so Obsidian resolves the correct workspace. Confirm supported syntax with the installed CLI before relying on optional commands. Typical read-only forms are:
(cd "$VAULT" && obsidian read path="$NOTE")
(cd "$VAULT" && obsidian search query="$QUERY")
Use read-only commands for backlinks, tags, or Bases results only when the
detector reports the CLI ready. Otherwise read files under $VAULT directly
and use rg for search. Reject absolute note arguments, traversal, symlinks, or
resolved paths outside the selected vault.
Mutation boundary
Do not use CLI create, write, append, property-set, daily-append, move, rename, or delete commands. Do not replace those commands with direct filesystem writes. Any knowledge or configuration change must be expressed as one reviewed transaction through the portable core; see operation transactions.
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.

wiki-cli is a skill published in the GitHub repository AgriciDaniel/claude-obsidian (15,675 stars, last pushed 2d ago), licensed MIT. It adds 74 tokens to every session and 667 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.

screenpipe-api
Query the user's local and synced-device data via the screenpipe REST API at localhost:3030 — recordings, audio, UI, meetings, connected services, and memory. Use for screen activity, other-device or cross-device history, productivity, media export, connections, durable memory, or discovering and automating saved…
follower-onboard
Onboard a new machine as a receive-only follower on a multi-machine agent network: it reads the shared vault, canon, skills and memory, runs nothing heavy locally (no RAG, reindex or GPU), and never receives executable hooks from the hub. Checklist-driven, with a verify step at each stage. Triggers: "/follower-onboard…
brain-onboard
An onboarding workflow that helps another person create and use their own private knowledge store, sometimes called a second brain. It gathers their information with consent, saves it in their own workspace, and demonstrates a first useful result.
memory-tidy
Tidy an agent's always-loaded memory index (MEMORY.md) on macOS or Linux: trim long lines, move closed entries to an archive, fold domains into hub files, restore dropped pins and add pointers for orphan memory files. Use when the index is over budget or has orphans. Triggers: /memory-tidy, /mt, tidy memory.
claudeai-sync
Pull new and changed claude.ai web conversations into an Obsidian vault, extract artifacts as first-class notes, concept-link them, and refresh the RAG index and dashboard. Idempotent: curated notes are never overwritten. Triggers: "/claudeai-sync", "pull claude.ai", "grab new claude.ai chats".
mine-channel
Mine any Telegram channel or chat for signal in one command: incremental zero-token scrape, deterministic detector shortlist, LLM judge for what is genuinely valuable to this owner, then linked vault notes, a database row, a map-of-content entry and reindex. Triggers: "/mine-channel ", "alpha from ".
