At a glance

Work with Obsidian vaults using the official obsidian CLI: read/search/create/edit notes, tasks, links, properties, plugins.

  • Knowledge Management work in your project
  • SKILL.md covers Requirements, Vault model, Command pattern and Common commands, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Obsidian is an agent skill from openclaw/openclaw. Work with Obsidian vaults using the official obsidian CLI: read/search/create/edit notes, tasks, links, properties, plugins.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management. It works with Obsidian. The repository describes itself as: The AI that really does things. Any OS. Any Platform. The lobster way. 🦞. The licence is MIT.

When your agent uses it

  • Knowledge Management work in your project

Example prompts

  • “/obsidian”

What it can do on your machine

Read from SKILL.md and the folder at commit 1eb5970. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Obsidian loads about 735 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~735

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Obsidian

Use the official obsidian CLI for Obsidian vault work. Vault files are plain Markdown, so direct file edits are still fine when safer/faster.

Requirements

  • Obsidian 1.12.7+ installed.
  • Settings -> General -> Command line interface enabled.
  • obsidian registered on PATH.
  • Obsidian app running; the CLI connects to the running app.

Check:

bash
obsidian version
obsidian help

macOS registration creates /usr/local/bin/obsidian pointing at the app-bundled CLI. Linux registration copies the binary to ~/.local/bin/obsidian.

Vault model

  • Notes: *.md.
  • Config: .obsidian/; avoid editing unless asked.
  • Canvases: *.canvas JSON.
  • Attachments: vault-configured folder.
  • Multiple vaults are common; pass vault="<name>" when ambiguous.

Obsidian desktop tracks vaults here:

  • ~/Library/Application Support/obsidian/obsidian.json

Command pattern

bash
obsidian <command> [name=value] [flag]
obsidian vault="Notes" search query="meeting notes" format=json

Parameter values with spaces need quotes. Add --copy to copy output where useful.

Common commands

Open/read:

bash
obsidian open file=Recipe
obsidian open path="Inbox/Idea.md" newtab
obsidian read
obsidian read file=Recipe

Search:

bash
obsidian search query="TODO" matches
obsidian search query="status::active" format=json
obsidian search:open query="project notes"

Create/modify:

bash
obsidian create name="New Note"
obsidian create path="Inbox/Idea.md" content="# Idea"
obsidian append file=Note content="New line"
obsidian prepend file=Note content="After frontmatter"

Move/delete:

bash
obsidian move file=Note to=Archive/
obsidian move path="Inbox/Old.md" to="Projects/New.md"
obsidian delete file=Note

Daily/tasks:

bash
obsidian daily
obsidian daily:read
obsidian daily:append content="- [ ] Review inbox"
obsidian tasks all todo
obsidian task file=Note line=8 done

Properties/links:

bash
obsidian tags all counts
obsidian property:read file=Note name=status
obsidian property:set file=Note name=status value=done
obsidian backlinks file=Note
obsidian unresolved verbose counts

Developer/debug:

bash
obsidian plugin:reload my-plugin
obsidian dev:errors
obsidian dev:screenshot file=shot.png
obsidian eval "app.vault.getFiles().length"

Notes

  • file=<name> uses Obsidian-style file resolution; path=<vault-relative.md> is exact.
  • Prefer CLI move/delete/property commands for Obsidian-aware updates.
  • Prefer direct Markdown edits for bulk text changes after locating the vault path.
  • Do not rely on third-party obsidian-cli unless user explicitly asks for it.
