What it does

Obsidian is an agent skill from HybridAIOne/hybridclaw. Read, search, organize, and create notes in the Obsidian vault.

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Knowledge Management. It works with Obsidian. The repository describes itself as: Enterprise-ready self-hosted AI assistant runtime with sandboxed execution, secure credentials, approvals, and memory. The licence is MIT.

When your agent uses it

  • Knowledge Management work in your project

Example prompts

  • “/obsidian”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. user-provided vault path
  2. remembered vault path from MEMORY.md
  3. OBSIDIAN_VAULT_PATH
  4. obsidian-cli print-default --path-only
  5. macOS config: ~/Library/Application Support/obsidian/obsidian.json
  6. common defaults

What it can do on your machine

Read from SKILL.md and the folder at commit 8162701. 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

    Shell commands in SKILL.md call:

    • rg

    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 841 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 364 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~18
When it runs · the whole SKILL.md, loaded when a task matches
~841

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

Obsidian vaults are normal folders on disk. Notes are usually *.md. Do not touch .obsidian/, *.canvas files, or plugin data unless the user explicitly asks.

Typical Vault Structure

  • notes: *.md
  • config: .obsidian/
  • canvases: *.canvas
  • attachments: images, PDFs, and other files in normal folders

Vault Location

Resolve the vault path first. Use this order:

  1. user-provided vault path
  2. remembered vault path from MEMORY.md
  3. OBSIDIAN_VAULT_PATH
  4. obsidian-cli print-default --path-only
  5. macOS config: ~/Library/Application Support/obsidian/obsidian.json Use the vault with "open": true.
  6. common defaults:
    • ~/Documents/Obsidian Vault
    • ~/Documents/Obsidian
    • ~/Library/Mobile Documents/iCloud~md~obsidian/Documents

Do not treat the current workspace as the vault unless the user explicitly says so, the workspace contains .obsidian/, or Obsidian's config points there.

If the resolved vault came from steps 3-6, tell the user which path you found and ask for confirmation before making write changes. For read-only discovery or search, you may proceed, but note the source of the vault path.

If you find a stable, unambiguous vault path, save a short fact to MEMORY.md, for example Obsidian vault: /absolute/path/to/vault. Do not save ambiguous or temporary vaults.

Quick Start

Assume:

bash
VAULT="/absolute/path/to/vault"

Prefer obsidian-cli when available for vault-aware search and safe moves. Otherwise use the shell commands below.

Pick default vault:

bash
obsidian-cli print-default --path-only
bash
printenv OBSIDIAN_VAULT_PATH
cat "$HOME/Library/Application Support/obsidian/obsidian.json"
  • Read: sed -n '1,220p' "$VAULT/Folder/Note.md" This is a bounded first read. If the note is longer than 220 lines, say so and continue with a wider or full read instead of pretending you saw the whole file.
  • List: rg --files "$VAULT" -g '*.md'
  • Search: obsidian-cli search "keyword" obsidian-cli search-content "keyword" Shell fallback: rg --files "$VAULT" -g '*.md' | rg -i 'keyword' rg -n --glob '*.md' 'keyword' "$VAULT"
  • Create: obsidian-cli create "Folder/New note" --content "# Title" Shell fallback: set -C && printf '# Title\n' > "$VAULT/Folder/New note.md"; set +C
  • Append: printf '\nNew content\n' >> "$VAULT/Folder/Existing note.md"
  • Move / rename: obsidian-cli move "Old Path/Note" "New Path/Note" Shell fallback: mv -n "$VAULT/Old Path/Note.md" "$VAULT/New Path/Note.md" If you move manually, search for and fix stale links before finishing.
  • Delete: obsidian-cli delete "Path/Note" Shell fallback: rm "$VAULT/Path/Note.md"

Wikilinks:

  • prefer [[Note Name]] when nearby notes use wikilinks
  • match the vault's existing frontmatter, heading, tag, and link style
  • search before creating to avoid duplicate notes
  • read before write; do not delete or overwrite notes unless the user asked
