obsidian

obsidian is a skill for Claude Code, Codex from sybil-solutions/local-studio. It costs 75 tokens per session (1,086 once invoked), scanned A, original, Apache-2.0.

A way to search, read, create, and extend notes in an Obsidian vault. Obsidian vaults are folders of Markdown files, and Markdown is plain text formatted with simple symbols.

In plain words
What is it for?
Use it to find notes, read recent or linked notes, create new notes, and add information to existing notes.
Why use it?
It lets an agent work with the notes already stored on the computer while preserving links between notes, metadata, and tags. It also avoids overwriting existing notes when creating or appending.

About the project

Local Studio is a local-first control panel for running, managing, and using self-hosted large language model backends such as vLLM, SGLang, llama.cpp, and ExLlama. It lets users launch models, monitor GPU and runtime state, chat through OpenAI-compatible endpoints, and run agent sessions from a desktop or connected mobile device. The catalogue skills and instruction support agent workflows with Local Studio and its controllers.

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.

Security

Grade A, and why

obsidian 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.

How it starts

The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

obsidian

An Obsidian vault is a folder of markdown files. There is no Obsidian process to talk to, no API, and no plugin installed on the Obsidian side — the obsidian_* tools read and write the files directly, and Obsidian picks the changes up on its own. If it is open, the user will see your note appear.

The vault is the user's own writing. Treat it that way: read a lot, write only what they asked for, and never present a note's contents as your own summary without saying which note it came from.

Tools

  • obsidian_vaults — every vault on this machine, which one is open, which is the default.
  • obsidian_search — find notes by title, content, or both. Returns paths plus the passages that matched.
  • obsidian_read — one note: body, frontmatter as fields, tags, and its wikilinks resolved to paths.
  • obsidian_recent — the notes modified most recently, with a preview line.
  • obsidian_backlinks — the notes that link TO a note, and the line each link sits on.
  • obsidian_create — a NEW note. Refuses to overwrite an existing one.
  • obsidian_append — add to the end of an existing note. Refuses when it does not exist.

Every tool takes an optional vault (folder name or full path). Omit it for the vault open in Obsidian, or the most recently opened one.

What Obsidian means, that a plain file reader gets wrong

  • [[wikilinks]] resolve by note NAME across the whole vault, not by relative path. [[Roadmap]] in a note buried three folders deep points at whichever note is called Roadmap, wherever it lives. [[Note|alias]] and [[Note#Heading]] still point at Note. obsidian_read resolves them for you and gives you the path; pass that path, or the bare name, straight to the next call.
  • Frontmatter is metadata, not the opening paragraph. The --- block at the top holds tags, aliases, and whatever properties the user keeps. obsidian_read returns it as fields and the body separately. Do not quote it back as if the note began with it.
  • Tags live in two places. tags: in frontmatter and #tag inline in the text. A note's tags are the union; searching for #idea covers both.
  • .obsidian/ is not notes. It is themes, hotkeys and workspace layout. The tools never search, read or write it. If the user asks about their Obsidian settings, say that these tools deliberately do not touch 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.
