obsidian-vault

obsidian-vault is a skill for Claude Code, Codex from sonichi/sutando. It costs 0 tokens per session (1,024 once invoked), scanned A, original, MIT.

A voice-controlled capture tool that writes notes, tasks, and thoughts directly into an Obsidian vault. Obsidian is a note-taking app that stores notes as files in folders.

In plain words
What is it for?
Use it to create standalone notes, append checkbox tasks, and add dated thought entries to the Sutando section of the vault.
Why use it?
It saves spoken information without sending it through an extra service or requiring an Obsidian plugin, and Obsidian can detect the new files while the vault is open.

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-vault 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 8d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/dream.py, tools.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

obsidian-vault

Voice-inline capture into a Sutando-owned Obsidian vault. The voice agent calls add_to_vault(kind, body, title?) directly — no core round-trip, no Obsidian plugin required. Filesystem-direct: Obsidian's watcher picks up the change instantly when the vault is open.

Vault

Lives at <workspace>/obsidian-vault/ (<workspace> resolved via bash scripts/sutando-config.sh workspace — per sutando.config.local.json, defaulting to <repo>/workspace/; $SUTANDO_WORKSPACE no longer honored as of v0.8 / #1440). Auto-created on first capture, with a .obsidian/ marker dir so Obsidian recognizes the folder as a vault.

Layout

Everything Sutando writes lives under the Sutando/ subfolder, by kind:

<workspace>/obsidian-vault/
  .obsidian/                                 ← marker; Obsidian populates on first open
  Sutando/
    Notes/<slug>-<YYYY-MM-DDTHHMMSS>.md      kind="note"   → standalone file w/ frontmatter
    Tasks.md                                 kind="task"   → appended checkbox
    Thoughts/<YYYY-MM-DD>.md                 kind="thought" → appended timestamped block

This subfolder convention keeps Sutando's writes out of the way of anything else you put in the vault later.

Triggers (what the voice agent listens for)

  • "save this as a note" / "note that X" → kind="note"
  • "add to my tasks" / "todo: X" / "remind me to X" → kind="task"
  • "remember this thought" / "log this idea" → kind="thought"
  • Ambiguous capture intents → the tool description picks thought for stream-of-consciousness, task for action-shaped, note otherwise.

One-time setup in Obsidian

Open Obsidian → File → Open vault → Open folder as vault → pick <workspace>/obsidian-vault. Obsidian will remember it. The vault appears empty until you trigger your first capture.

Opt-in: agent-state mirror + nightly dream

add_to_vault (the voice-inline capture tool) is always available — it only writes when you explicitly say "save this as a note" / "todo: ..." / "thought: ...".

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
