obsidian-vault

obsidian-vault is a skill for Claude Code, Codex from espennilsen/pi. It costs 46 tokens per session (1,656 once invoked), scanned A, original, MIT.

A set of rules for managing Espen's Obsidian vault, a folder of linked Markdown notes. It follows the PARA organization method, which separates projects, ongoing responsibilities, reference material, and archives.

In plain words
What is it for?
Use it to find or manage notes, tasks, projects, dashboards, and daily logs while following the vault's required files, folders, metadata, and tags.
Why use it?
It helps keep notes in the vault's existing structure and protects its automated dashboards and templates from accidental breakage. Changes require confirmation before files are created, edited, or deleted.

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 1 finding 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.

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.

Obsidian Vault Management

Vault Location

/Users/espen/Library/CloudStorage/OneDrive-Espennilsen.net/2-Areas/Digital_Life/Obsidian/e9n

⚠️ Safety

Always confirm with Espen before creating, modifying, or deleting any vault file.

The vault has established automation (Dataview queries, Templater templates, dashboards). Breaking these patterns can cascade.

Before Making Changes

  1. Read the vault's own AGENTS.md for full context on structure, plugins, workflows, and conventions
  2. Read the relevant _Index.md file for the section you're working in
  3. Check the 🏷️ Tag Taxonomy.md for correct tag usage

Structure (PARA)

1. Projects/     — Active initiatives with deadlines
2. Areas/        — Ongoing responsibilities (Education, Finance, Health, Personal Dev, Romance)
3. Resources/    — Reference materials (AI, Books, Career, Homelab, Languages, Programming)
4. Archive/      — Completed or inactive items
Notes/           — Daily/Weekly/Monthly notes with habit tracking
Tasks/           — TaskNotes (one task per note)
Templates/       — 23+ Templater templates
Weekly Reviews/  — Periodic reflections

Conventions

  • Frontmatter is required on all notes: created, modified, type, tags at minimum
  • Tags follow the taxonomy: #project/active, #type/note, #status/active, #priority/high, #area/professional
  • File naming: Use descriptive names. TaskNotes use format: Project - Task Description.md
  • Templates: Always use existing templates rather than creating notes from scratch. Check Templates/ first.
  • Links: Use [[wiki-links]] for internal references
  • Dataview: Many notes contain Dataview queries. Don't break the query syntax when editing.

Obsidian Local REST API

The vault has the Local REST API plugin (v3.4.3) running. Prefer this over direct filesystem access — it respects Obsidian's internal state, caches, and metadata.

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.
