Obsidian Markdown Skill for Claude
Explain, draft, or validate Obsidian Flavored Markdown syntax: properties, wikilinks, embeds, callouts, tags, comments, highlights, block references, math, and Mermaid. Use when the user explicitly requests Obsidian note formatting or syntax help, not for general Markdown or broad vault operations.

Use this as a compact fallback for Obsidian-specific syntax. Prefer a separately
installed kepano/obsidian-skills obsidian-markdown skill when available,
then current Obsidian Help, for detailed or
version-sensitive questions.
Resolve the installed product root from this skill's own location, not from the
vault or current working directory:
PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
CORE="$PRODUCT_ROOT/scripts/claude-obsidian.py"
test -f "$CORE"
Answer syntax questions read-only. If the user requests a vault edit, draft the
complete note, read operation-transactions.md,
and build one claude-obsidian.transaction.v1 bundle with
operation_type: markdown and only wiki/ targets. Inspect it, then set
APPROVAL_SHA256 to the returned approval_sha256 after review and apply it
through the same vault-bound plan. A canonical page create or removal includes
an active index or MOC update in that bundle; update the overview only when its
stable high-level synthesis changed:
python3 "$CORE" transaction inspect "$BUNDLE" --vault "$VAULT"
python3 "$CORE" transaction apply "$BUNDLE" --vault "$VAULT" \
--approved-plan-sha256 "$APPROVAL_SHA256"
Never write a note directly.
Properties
Use flat YAML properties and YYYY-MM-DD dates. Quote wikilinks inside YAML.

---
Do not nest objects in generated wiki properties. Use block lists rather than
inline YAML arrays. Quote numeric-only tag values, for example - "2026", so
YAML parsers preserve them as tags instead of numbers. Keep unknown existing
properties unless the requested edit changes them.
Wikilinks and embeds
[[Note Name]]
[[Note Name|Display text]]
[[Note Name#Heading]]
[[Note Name#^block-id]]
[[Folder/Note Name]]
This paragraph is addressable. ^evidence-block
![[Note Name#Summary]]
![[diagram.png|480]]
![[paper.pdf#page=3]]
Match the target filename exactly. Use a vault-relative folder path when a
basename is ambiguous. Use standard Markdown links for external URLs; use
wikilinks for this vault's notes.
Callouts
> [!note]
> Supporting context.
> [!warning] Review required
> This claim has contradictory evidence.
> [!question]- Open question
> What evidence would resolve this?
- starts collapsed and + starts expanded. Common built-in types include
note, abstract, info, todo, tip, success, question, warning,
failure, danger, bug, example, and quote. Preserve custom vault
callout types rather than rewriting them.

Source --> Claim
Standard CommonMark/GFM headings, lists, tasks, tables, code fences, and
footnotes remain valid. Avoid HTML when native Markdown is sufficient.
Validate a drafted note
- Parse the YAML boundary and keep property types consistent.
- Verify every internal target, heading, and block reference that can be
checked locally; never fabricate a target to make a link look complete.
- Keep evidence wording distinct from inference and preserve source locators.
- Ensure code fences and callout quoting are balanced.
- Run deterministic wiki lint after a requested mutation and report remaining
findings without silently repairing them.
For source-cited pages, also follow
provenance.md. Report the transaction
operation ID and exact changed paths after an applied edit.

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
Create and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties, and other Obsidian-specific syntax. Use when working with .md files in Obsidian, or when the user mentions wikilinks, callouts, frontmatter, tags, embeds, or Obsidian notes.
