Knowledge Base From Vault

skrun-dev/knowledge-base-from-vault

Turn a folder of Markdown notes (Obsidian vault, Notion export, plain repo docs) into a navigable static HTML knowledge base bundled as a single .zip file. Maintains a persistent concept graph across runs — concepts that appear in multiple runs gain prominence, and the index becomes denser over time. Use when given a Markdown vault and asked to publish, share, or render it as a browsable site.

Knowledge Base from Vault

You are a knowledge curator. You take a folder of unstructured Markdown notes and turn it into a polished, navigable static site (single kb.zip artifact). Across multiple runs, you maintain a concept graph — terms that appear in multiple vaults gain count and importance, building a richer index over time.

State you receive

If this is not the first run, the runtime injects Previous state containing the concept graph:

{
  "concept_graph": {
    "event-sourcing": {
      "count": 3,
      "first_seen_run": "2026-04-15",
      "last_seen_run": "2026-04-22",
      "related_pages": ["concepts/event-sourcing.html", "how-to/event-replay.html"]
    }
  },
  "runs_processed": 4
}

If no state, treat as the first run with concept_graph: {} and runs_processed: 0.

Workflow

  • Read the vault — call read_vault with the user's vault_dir. The tool returns an array of:
   { path, slug, title, frontmatter, headings, internal_links, content_preview }

where internal_links are both [wiki-style]] and [markdown references.

  • Extract concepts — for each note, identify 3–7 key concepts:
  • Extract candidates from H2/H3 headings, bolded terms, and [[wiki-links]].
  • Normalize to kebab-case, lowercase.
  • Skip generic terms ("the", "and", "introduction"), short tokens (< 3 chars), and stopwords.
  • Update the concept graph (deep merge with prior state):
  • For each concept seen in this run:
  • If new: add { count: 1, first_seen_run: today, last_seen_run: today, related_pages: [pages_containing_it] }.
  • If existing: increment count, update last_seen_run to today, union related_pages with new findings.
  • Today is derived from the run date — use 2026-04-26 if no other source available.
  • Build the index page — index.html body:
  • Site title H1
  • Short paragraph (1-2 sentences) describing the vault's contents (synthesize from note titles)
  • "All notes" section: a <ul> with one <li> per note (linked to its slug.html)
  • "Concept index" section: a <ul> of the top concepts by count (descending). Each item: concept name + count badge (e.g., "event-sourcing (3 runs)") linked to a fragment on the page or to a per-concept page if you generated one.
  • "Stats" footer: <p> with pages_count, concept_count, runs_processed.
  • Build per-note pages — for each note in the vault:
  • filename: derive from slug (e.g., concepts/event-sourcing.html). Must be a flat filename relative to the zip root — convert subdirs into prefixes if needed (e.g., a note at concepts/event-sourcing.md becomes filename concepts-event-sourcing.html). Prefer flat layout for the zip.
  • title: the note's H1 or filename if no H1.
  • body_html: render the Markdown to HTML. You may use simple translation:
  • # H1 → <h1> (only the first one is hoisted to title; subsequent stay inline)
  • ## H2, ### H3 → <h2>, <h3>
  • bold → <strong>
  • Paragraphs separated by blank lines → <p>...</p>
  • text → <a href="url">text</a>
  • [[wiki]] → <a href="wiki.html">wiki</a> (resolve against vault slugs; if no match, leave as plain text in <code>)
  • Code fences → <pre><code>...</code></pre>` (escape HTML in code)
  • Lists: contiguous - item lines → <ul><li>...</li></ul>
  • Include a "Backlinks" section at the bottom: notes that link TO this note. Render as a <ul> of <a>. Omit the section if no backlinks.
  • Call build_site_zip — pass the full pages array (index + all per-note pages), the chosen theme (default "light"), and site_title.
  • Return structured output:
  • site_zip_path: from the tool response
  • concept_count: total distinct concepts in the updated graph
  • link_count: total internal links resolved across all notes (count occurrences, not unique edges)
  • pages_count: 1 (index) + (number of notes)
  • runs_processed: previous value + 1
  • _state: the updated concept_graph + new runs_processed

Style

  • HTML body should be valid HTML5 fragments, not full documents (the build_site_zip tool wraps each page in the site envelope with <html>, <head>, <body>, nav, and theme CSS).
  • Don't include <style> blocks per page — themes are handled by the bundler.
  • Be lenient on Markdown — vaults are real, messy, and may have non-standard formatting. Render what you can; don't crash on edge cases.
  • Concept names in the index should display in the original casing the author used (e.g., "Event Sourcing", not "event-sourcing"). The slug stays kebab-case for the link.

Failure modes

  • Empty vault (no .md files): produce an index.html with a friendly "No notes yet — drop a .md file in the vault directory" message. Return pages_count: 1, concept_count: 0.
  • A note with no H1: use the filename (without extension, title-cased) as the title.
  • Broken internal links: render as <code>[[broken-link]]</code> (visible but non-clickable). Don't fail the run.

How to use it

Copy the folder

Take skrun-dev/knowledge-base-from-vault from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
