Vault Scribe

Vault Scribe — Obsidian + GitHub Markdown Skill

Creates and edits Markdown that is GitHub-Flavored Markdown (GFM) first, with optional Obsidian-specific extensions when needed. Standard Markdown (headings, bold, italic, lists, quotes, code blocks, tables) is assumed knowledge.

> Default rule: Use standard GFM syntax unless the user explicitly requests Obsidian-specific features or is working in an Obsidian-only context. Obsidian wikilinks ([[Note]]) break on GitHub — always prefer standard Markdown links for cross-platform compatibility.

When invoked with an argument (e.g. /vault-scribe meeting), use $ARGUMENTS to determine the note type. If no argument is provided, infer the type from the source material or ask the user.

Workflow: Creating a Note

1. Analyse the Source Material

• Read the full transcript, notes, or brief carefully
• Identify the core topic, intended audience, and key concepts
• Note any implicit structure (e.g., problem → solution → examples)
• Extract any explicit examples, warnings, tips, or quotes worth preserving

2. Generate YAML Front Matter

> Reference: See references/FRONT-MATTER.md for the complete schema definitions, all enum values, and type-specific required fields.

First, determine the note type based on what the user is creating:

| If the user wants… | Set type to | |---|---| | A guide, reference doc, or knowledge article | article | | A step-by-step instructional guide or procedure | how-to | | Architecture docs, RFCs, design docs, system specs | technical | | An investigation with multiple sources | deep-research | | A versioned plan or strategy document | strategy | | Meeting notes, 1:1s, standups, retrospectives | meeting | | Brainstorming, ideation, or exploratory thinking (solo or group) | brainstorming |

> [!TIP] > Brainstorming is its own note type. It works for group sessions (add attendees and meeting_date) and solo AI ideation (omit them). Add sources when the brainstorm draws on external references.

Then apply the corresponding frontmatter schema from references/FRONT-MATTER.md. Every note type uses the core fields plus any type-specific required fields.

Tag guidelines:

• Use lowercase, hyphenated slugs only (e.g. distributed-systems, not Distributed Systems)
• Include 4–8 tags: topic-specific first, then broader domain tags
• Always include at least one technology tag and one domain/concept tag

3. Structure the Document Body

Use this hierarchy:

# Title (H1) — matches front matter title
## Section (H2) — major topic areas
### Subsection (H3) — specific concepts within a section

Target sections (adapt names to the topic):

1. Overview / What is X? — define the subject clearly
2. How It Works — mechanics, process, or architecture
3. Practical Examples — concrete code blocks or walkthroughs
4. Common Mistakes / Warnings — callout blocks
5. Quick-Start / Checklist — actionable summary
6. Further Reading & References — links table

> [!NOTE] > Minimum 4 sections (Overview, How It Works, Examples, References) for all notes. The full 6 sections are the target for comprehensive articles and guides. Simpler note types (meetings) naturally use fewer sections.

4. Apply Callout Blocks

Use GFM Alerts by default (renders on both GitHub and Obsidian). See references/CALLOUTS.md for the full list of callout types including Obsidian-only variants.

| Callout Type | Use For | |---|---| | [!NOTE] | Neutral supplementary info | | [!TIP] | Actionable best practice | | [!IMPORTANT] | Key concept the reader must not miss | | [!WARNING] | Common mistake or gotcha | | [!CAUTION] | Risk of data loss, security issue, or breaking change |

> [!TIP] > Every Warning, Tip, and TL;DR should be a callout block — not plain prose. This makes the document scannable.

5. Code Blocks

Always use fenced code blocks with a language identifier:

````markdown

key: value

mkdir -p ~/.claude/skills/my-skill

````

For directory trees, use plain text or no language tag.

6. Table of Contents

Never use [TOC], [[_TOC_]], or any other TOC directive — neither GitHub nor Obsidian supports them natively. They render as broken plain text.

• GitHub auto-generates a TOC in the sidebar — no directive needed.
• Obsidian generates one via its built-in plugin — no directive needed.
• Only add a manual TOC (using standard anchor links) when the document has 6+ sections and will be read outside a browser. See references/MARKDOWN-SYNTAX.md for anchor rules and an example.

7. Tables & Links

Use Markdown tables for comparisons, option lists, and reference links. Always include a reference links table at the end:

| Resource | Link |
|---|---|
| Official Docs | [docs.example.com](https://docs.example.com) |
| Source Video  | [youtube.com/watch?v=...](https://youtube.com/watch?v=...) |

8. Inline Formatting Rules

| Element | Usage | |---|---| | **bold** | Key terms on first use, critical values | | *italic* | Titles of external resources, emphasis | | ` code | All file paths, commands, config keys, code symbols | | [[wikilink]]` | Internal Obsidian links (only if Obsidian-only context) |

9. Transcript Appendix

When the source material includes a transcript (video, podcast, meeting recording, article), always append the raw transcript at the very end of the document, after all other content, using this exact format:

---

## Transcript

Transcript from: []()
Date of material: 

\```

\```

• The transcript section is separated from the rest of the document by a horizontal rule (---)
• The source name must be a clickable Markdown link when a URL is available
• If no URL exists, use plain text for the name
• Date should be in YYYY-MM-DD format when known; leave blank if unknown
• Before appending, scan the transcript for sensitive values and replace each match with [REDACTED]. Patterns to detect (case-insensitive):
• API keys and tokens: strings matching sk-[A-Za-z0-9]{20,}, AKIA[A-Z0-9]{16}, AIza[0-9A-Za-z\-_]{35}, ghp_[A-Za-z0-9]{36}, Bearer [A-Za-z0-9\-._~+/]+=*
• Passwords in URLs: ://[^:]+:[^@]+@ (replace the password segment only)
• Connection strings: DSN-style strings containing password=, pwd=, passwd= followed by a value
• Private key blocks: anything between -----BEGIN ... KEY----- and -----END ... KEY-----
• Generic high-entropy secrets: any token-like value assigned to a key named key, secret, token, password, passwd, pwd, credential, or api_key (case-insensitive)
• If no sensitive patterns are found, content is preserved unchanged
• The raw transcript goes inside a fenced code block with no language tag

Output Requirements

• File extension: .md
• Encoding: UTF-8
• Front matter: Always present, always first
• Minimum sections: 4 (Overview, How It Works, Examples, References). Target 6 for comprehensive articles.
• All external URLs must be real and formatted as [label](url)
• No bare URLs — always wrapped in Markdown link syntax
• End the document with an [!abstract] callout containing the TL;DR (before the Transcript appendix, if present)

---

• [ ] category is a valid enum value
• [ ] Tags are lowercase and hyphenated
• [ ] All warnings/tips are callout blocks, not plain paragraphs
• [ ] At least one code block example is present (for articles/guides)
• [ ] A reference links table exists at the end
• [ ] Document closes with an [!abstract] callout (before Transcript appendix if present)
• [ ] No bare URLs (all links use [label](url) format)
• [ ] date_created and date_updated are set (use today's date if unknown)
• [ ] If source material includes a transcript, it is appended in the Transcript Appendix format
• [ ] Transcript appendix has been scanned for credentials; any sensitive values are replaced with [REDACTED]
