obsidianos_work: Skill for Claude Code

.agents/skills/obsidian-markdown/SKILL.md

obsidian-markdown is a skill for Claude Code, Codex from benoror/obsidianos_work. It costs 71 tokens per session (1,439 once invoked), scanned A, a copy of obsidian-markdown, MIT.

A helper for writing Obsidian notes, which are Markdown files stored in the Obsidian note-taking app. It supports Obsidian's extra syntax for internal links, embedded files, highlighted callouts, properties, and tags.

In plain words
What is it for?
It helps create and edit `.md` notes with frontmatter, wikilinks such as `[[Note]]`, embeds for notes, images, or PDFs, callouts, tags, and other Obsidian features.
Why use it?
It prevents notes from using invalid or inconsistent Obsidian-specific formatting. It also provides a way to check that notes render correctly in Obsidian's reading view.

This is benoror/obsidianos_work's own configuration. It tells Claude Code and Codex how to work on obsidianos_work itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything obsidianos_work configures →

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-markdown 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 9d 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.

Origin

Obsidian Flavored Markdown Skill

Usage

Use when editing vault .md notes and the user needs wikilinks, embeds, callouts, frontmatter/properties, tags, or other Obsidian-specific Markdown.

Create and edit valid Obsidian Flavored Markdown. Obsidian extends CommonMark and GFM with wikilinks, embeds, callouts, properties, comments, and other syntax. This skill covers only Obsidian-specific extensions -- standard Markdown (headings, bold, italic, lists, quotes, code blocks, tables) is assumed knowledge.

Workflow: Creating an Obsidian Note

  1. Add frontmatter with properties (title, tags, aliases) at the top of the file. See PROPERTIES.md for all property types.
  2. Write content using standard Markdown for structure, plus Obsidian-specific syntax below.
  3. Link related notes using wikilinks ([[Note]]) for internal vault connections, or standard Markdown links for external URLs.
  4. Embed content from other notes, images, or PDFs using the ![[embed]] syntax. See EMBEDS.md for all embed types.
  5. Add callouts for highlighted information using > [!type] syntax. See CALLOUTS.md for all callout types.
  6. Verify the note renders correctly in Obsidian's reading view.

When choosing between wikilinks and Markdown links: use [[wikilinks]] for notes within the vault (Obsidian tracks renames automatically) and standard Markdown links with an https:// URL for external pages only.

[[Note Name]]                          Link to note
[[Note Name|Display Text]]             Custom display text
[[Note Name#Heading]]                  Link to heading
[[Note Name#^block-id]]                Link to block
[[#Heading in same note]]              Same-note heading link

Define a block ID by appending ^block-id to any paragraph:

This paragraph can be linked to. ^my-block-id

For lists and quotes, place the block ID on a separate line after the block:

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.
