Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.01009 |
| Opus 5 | $0.00056 | $0.00504 |
| Sonnet 5 | $0.00022 | $0.00202 |
| Haiku 4.5 | $0.00011 | $0.00101 |
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 12d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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)
- Read the vault's agent constitution if present — a
CLAUDE.md,AGENTS.md, orGEMINI.mdat the vault root carries routing rules specific to that vault. Vault instructions win over this skill. - Open the relevant hub/MOC or board to load context for what you're about to write.
- Check an existing note of the same type — match its frontmatter, folder, and naming before creating a new one.
- 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 +
.baseYAML 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 ships with it
7 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.
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.

obsidian-writing is a skill published in the GitHub repository GalaxyRuler/Galactic-skills (5 stars, last pushed 6d ago), licensed MIT. It adds 112 tokens to every session and 1,009 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
