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-writing 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 2mo 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.

Obsidian Writing

Methodology for working inside an Obsidian vault: native Markdown, queries, dashboards, automation, and an optional opinionated vault-management system that keeps a growing vault from drifting. Replace every <placeholder> with your own vault's values.

Orient before writing (30 seconds)

  1. Read the vault's agent constitution if present — a CLAUDE.md, AGENTS.md, or GEMINI.md at the vault root carries routing rules specific to that vault. Vault instructions win over this skill.
  2. Open the relevant hub/MOC or board to load context for what you're about to write.
  3. Check an existing note of the same type — match its frontmatter, folder, and naming before creating a new one.
  4. Never stage .obsidian/ (app state) in a commit.

Tool choice — narrowest surface that proves the result

Need Prefer
Note CRUD, search, move, command-palette action Obsidian MCP (mcp__obsidian__* or however your server is named) if exposed; else the Local REST API
Live Dataview refresh, open-note state, palette action REST/MCP POST /commands/execute
.base / .canvas, byte-level edits, bulk rename, git ops Filesystem edit; reload/open in Obsidian afterward

Using MCP/REST keeps Obsidian's index, frontmatter parser, and link graph consistent. Don't guess live render state from file text when the user reports a UI/render problem — capture the exact error via REST/MCP or the obsidian CLI.

Markdown essentials

[[Note]], [[Note|alias]], [[Note#Heading]], [[Note#^block]], ![[Note]], ![[img.png|300]]. Prefer [[wikilinks]] (rename-safe) for internal links; use [label](https://…) only for external URLs. Callouts: > [!note], > [!warning] Title, > [!faq]- (collapsed). Full syntax → MARKDOWN-SYNTAX.md.

Reference files

  • MARKDOWN-SYNTAX.md — wikilinks, embeds, callouts, block IDs, comments, highlights, math, tags, frontmatter
  • QUERIES.md — Dataview tables and Tasks query blocks, generalized patterns + live-refresh
  • CANVAS-AND-BASES.md — JSON Canvas authoring rules + .base YAML dashboards
  • PLUGINS.md — high-leverage plugin playbook (Templater, Dataview, Tasks, citations, Smart Connections, Breadcrumbs, Mermaid, Pandoc, sync/git, REST API/MCP)
  • VAULT-SYSTEM.md — optional opinionated system: one-note-one-home routing, frontmatter schemas, self-routing templates, anti-drift checklist, project-board ritual, literature workflow

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.
