vault-writer

vault-writer is a skill for Claude Code from uetzel/AutoADHD. It costs 130 tokens per session (2,811 once invoked), scanned A, original, MIT.

A rulebook for creating and editing notes in an Obsidian vault, a folder of linked Markdown notes. It defines note structure, source tracking, protected fields, and links between related notes.

In plain words
What is it for?
Use it when creating or updating notes about people, events, decisions, actions, places, organisations, reflections, or other knowledge in the vault.
Why use it?
It prevents notes from losing their sources, changing protected information, or becoming disconnected and inconsistent.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md; mentions Codex.

Not installable on its own: it runs a file from its repository that does not travel with it. Clone the repository, or install whatever ships that file. The line is ./Meta/scripts/queue-review.sh "Canon/People/[[Name]].md" "field" "value" "reason".

Install

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

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

vault-writer 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 — 307 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vault Writer

You're writing notes in an Obsidian vault that serves as a personal operating system. Every note follows specific rules so that AI agents (Extractor, Reviewer, Implementer) can process them reliably, and so the human can scan them visually with ADHD-friendly formatting.

This skill contains everything you need. Don't rely on remembering CLAUDE.md — the rules are right here.


The Golden Rules

  1. Provenance is sacred. Every fact traces to a human moment or explicit source. Add source: to frontmatter. Add <!-- source: ... --> comments on AI-added content.
  2. Locked fields are untouchable. If frontmatter has a locked: array, those fields cannot be changed by AI. Period. If new info contradicts a locked field, keep the locked value.
  3. Wikilinks are structure. Every mention of a known person, event, concept, action, decision = a wikilink. Before linking, verify the target exists. If it doesn't, create a stub or note it's missing.
  4. Never touch # Raw sections. Raw transcripts in Inbox notes are source evidence. Read-only.
  5. Never fabricate. If unsure, say so.

Frontmatter Template

Every note needs at minimum:

---
type: person | event | concept | decision | project | action | place | organization | reflection | belief | emerging | ai-reflection
name: Human Readable Name
created: YYYY-MM-DD
updated: YYYY-MM-DD
source: voice | human | ai-extracted | ai-generated | ai-enriched
---

Additional fields are welcome when useful (aliases, status, tags, linked, locked, etc.) but not required except for specific types below.

Source Values

  • voice — spoken by human in a voice memo
  • human — typed/written directly by human
  • ai-extracted — AI pulled from a voice memo transcript
  • ai-generated — AI created (research, enrichment, reflection)
  • ai-enriched — AI added content to a human-created note

Agent Attribution (MANDATORY)

Every AI action must identify WHICH agent did it and WHEN. Generic "ai-generated" is not enough.

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.
