description

Import a wiki knowledge graph into the current vault — either from a graph.json export file (stubs) or from an OKF (Open Knowledge Format) markdown bundle (full page bodies). Use this skill when the user says "import wiki", "import from export", "load graph.json", "import vault", "import OKF bundle", "import OKF", "load OKF", "import markdown bundle", "/wiki-import", or wants to transfer pages from one vault to another using the output of wiki-export.

Wiki Import — Reconstruct Pages from an Export

You are importing a vault's knowledge into the current vault from one of two sources produced by wiki-export:

• graph.json — the graph skeleton. Reconstructs page stubs (frontmatter, typed relationships, a ## Related link list — no body). Lossy.
• OKF bundle (a wiki-export/okf/ directory) — the actual markdown files. Reconstructs full pages with their real bodies. Lossless. Use this for true vault-to-vault transfer.

Either way, the import writes pages with correct frontmatter and wikilinks, then updates all vault metadata. Step 2, Step 3 (graph only), and Step 5 are shared; Step 4 forks by source type.

Before You Start

Writing profile: Before drafting or rewriting natural-language Markdown, read and apply the Writing Profile Resolution section in llm-wiki/SKILL.md. Framework schema, provenance, safety, and operation-specific requirements take precedence. Preserve imported source prose; apply WRITING.md preferences only to newly generated metadata or stubs.

1. Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global config → prompt setup). This gives OBSIDIAN_VAULT_PATH.
2. Read $OBSIDIAN_VAULT_PATH/AGENTS.md if it exists — apply any owner-specific conventions.

Step 1: Locate and Detect Source Type

Find the import source:

• If the user provided a path argument, use it directly.
• Otherwise auto-detect, in order: ./wiki-export/okf/ (a directory) → ./wiki-export/graph.json (a file).
• If neither exists, ask the user for the path.

Detect the source type:

• The path is a file ending in .json → graph.json import (validate below, then Step 3 + Step 4-Graph).
• The path is a directory containing .md files with OKF frontmatter (a type: key), and/or a root index.md with okf_version → OKF bundle import (skip Step 3; go to Step 4-OKF).
• Anything else → report what's wrong and stop.

Validate a graph.json source:

• Must be valid JSON
• Must have top-level keys: nodes (array), links (array), graph (object)
• Must have at least 1 node

If validation fails, report what's wrong and stop.

Validate an OKF bundle source:

• Must contain at least 1 non-reserved .md file (i.e. not index.md/log.md) with parseable YAML frontmatter containing a non-empty type.
• A .md with no frontmatter or no type is skipped (with a count), not fatal — OKF consumers are permissive (OKF §9).

Show a preview before importing:

graph.json:

Import preview (graph.json — stubs)
  Source: <path>  (exported at <graph.exported_at>)
  Nodes:  N total  (concepts: A, entities: B, skills: C, references: D, ...)
  Links:  M edges  (X typed, Y untyped)
  Target: $OBSIDIAN_VAULT_PATH

OKF bundle:

Import preview (OKF bundle — full pages)
  Source: <dir>  (okf_version <ver if present>)
  Pages:  N total  (concepts: A, entities: B, skills: C, references: D, ...)
  Target: $OBSIDIAN_VAULT_PATH

Step 2: Determine Conflict Resolution Mode

Read the user's phrasing to determine mode. Default is merge.

Mode	Trigger phrases	Behaviour
merge	(default, no special phrasing)	Existing pages: update frontmatter tags/summary/relationships and add missing wikilinks; new pages: create stub.
skip	"skip existing", "don't overwrite", "only new pages"	Leave existing pages completely untouched; only create pages that don't exist yet.
overwrite	"overwrite", "replace existing", "force import"	Replace all matched pages with freshly reconstructed stubs regardless of existing content.

Step 3: Build Internal Maps (graph.json only — skip for OKF bundles)

Before writing anything, build two maps from the links array:

Adjacency map — for each node id, collect all neighbour ids (edges in either direction):

adjacency["concepts/transformers"] = ["entities/vaswani", "concepts/lstm", ...]

Typed edge map — for each node id, collect outgoing typed edges only (typed: true):

typed_edges["concepts/transformers"] = [
  {target: "concepts/lstm", relation: "contradicts"},
  ...
]

Step 4-Graph: Reconstruct Pages from graph.json (graph.json source only)

Record counts: created = 0, skipped = 0, merged = 0.

For each node in nodes:

1. Compute page_path = $VAULT/<node.id>.md
2. Ensure the parent directory exists (e.g. $VAULT/concepts/)
3. Check if the file already exists:
   • merge mode (default) + exists → read existing file, apply merge logic (see below), increment merged
   • merge mode (default) + doesn't exist → proceed to create stub, increment created
   • skip mode + exists → increment skipped, continue to next node
   • skip mode + doesn't exist → proceed to create stub, increment created
   • overwrite mode + exists → proceed to write fresh stub (overwrite), increment merged
   • overwrite mode + doesn't exist → proceed to create stub, increment created

# <node.label>

<node.summary paragraph if available, else omit>

## Related



 [[]] — 

 [[]]

If adjacency[node.id] is empty, omit the ## Related section entirely.

Merge logic (merge mode, existing page)

1. Read the existing page's frontmatter.
2. Tags: union of existing tags and node.tags (deduplicated, keep existing order, append new ones).
3. Summary: if the existing page has no summary field and node.summary exists, add it.
4. Relationships: union of existing relationships: entries and typed_edges[node.id] — skip entries where the same (target, type) pair already exists.
5. Updated: set updated to the current ISO timestamp.
6. Body: scan for a ## Related section. If it exists, append any missing wikilinks from adjacency[node.id] that aren't already linked anywhere in the body. If no ## Related section exists, append one with the missing links.
7. Leave the rest of the body untouched.

Step 4-OKF: Reconstruct Pages from an OKF bundle (OKF source only)

Record counts: created = 0, skipped = 0, merged = 0, unparseable = 0.

Walk the bundle directory tree. For each .md file that is not a reserved file (index.md, log.md):

1. Parse the YAML frontmatter. If it has no frontmatter or no non-empty type, increment unparseable and skip the file.
2. Compute the concept id = the file's path relative to the bundle root, with .md stripped (e.g. concepts/transformers.md → concepts/transformers). The target page is $VAULT/<concept-id>.md.
3. Reverse-map frontmatter (the inverse of the canonical mapping table in wiki-export Step 3.5):
   • title ← title.
   • category ← the preserved category extension key if present; else lower-case the directory prefix of the concept id (concepts/… → concepts); else derive from type (Concept→concepts, Entity→entities, Skill→skills, Reference→references, Synthesis→synthesis, Project→projects, Journal→journal).
   • tags ← tags.
   • summary ← description.
   • updated ← timestamp (or now if absent).
   • created ← the preserved created extension key if present, else now.
   • sources ← the preserved sources extension key if present; else ["imported from OKF bundle <bundle path>"]. If a resource URL is present and not already in sources, add it.
   • Carry through any other preserved extension keys verbatim (relationships, lifecycle, tier, base_confidence, …). These make the round-trip lossless.
4. Reverse-transform body links — markdown links that point at .md paths become wikilinks (this restores both real cross-links and forward-references the exporter preserved per Step 3.5):

Unlike the graph.json path, do not generate a ## Related stub section — the bundle body already contains the real cross-links.

Step 5: Update Vault Metadata

.manifest.json

Add a new entry keyed by the canonical path of the graph.json file:

"<absolute path to source>": {
  "ingested_at": "<ISO timestamp>",
  "source_type": "wiki-export",
  "pages_created": ["list/of/created/pages.md"],
  "pages_updated": ["list/of/merged/pages.md"]
}

Set source_type to "wiki-export" for a graph.json import or "okf-bundle" for an OKF bundle import. Key the entry by the absolute path of the source (the graph.json file or the bundle directory).

Also increment:

• stats.total_sources_ingested by 1
• stats.total_pages by the count of pages actually created (not skipped/merged)

If .manifest.json doesn't exist, create it with the standard structure:

{
  "stats": {
    "total_sources_ingested": 1,
    "total_pages": <created count>
  },
  "<graph.json path>": { ... }
}

index.md

For each created or merged page:

• Add or update the entry under its category section using the format: - [[<id>]] — <summary or title> ( #tag1 #tag2) (Note: space before ( — description ( #tag) not description(#tag))

Keep categories sorted alphabetically. Create the category section if it doesn't exist.

log.md

Append one line:

- [<ISO timestamp>] IMPORT source="<graph.json path>" pages_created=<N> pages_skipped=<K> pages_merged=<M>

hot.md

Rewrite the Recent Activity section to include this import as the latest entry:

- [<timestamp>] IMPORT from <graph.json path> — created X, merged Z pages

Update the updated: frontmatter timestamp. Leave other hot.md sections (Active Threads, Key Takeaways) intact unless they reference pages that were just created — in which case add brief mentions.

Step 6: Print Summary

Wiki import complete → $OBSIDIAN_VAULT_PATH
  Source:  <source path>  (<graph.json | OKF bundle>)
           <graph: exported at <graph.exported_at>, N nodes, M links | okf: N pages, okf_version <ver>>
  Created: <X> pages
  Merged:  <Z> pages  (existing pages updated)
  Skipped: <Y> pages  (only when --skip mode was used)

Only show the Skipped line if skip mode was explicitly requested. If overwrite mode was used, label merged pages as Replaced instead. For an OKF import, also report Unparseable: <U> files (no frontmatter/type, skipped) when U > 0.

Notes

• Stub vs full pages: A graph.json import produces stubs — structure and wikilinks but no body, a starting point for future ingestion. An OKF bundle import produces full pages with real bodies — it is the lossless, content-bearing path and the right choice for vault-to-vault transfer.
• Re-running is safe: The default merge mode is idempotent — re-running on an unchanged export will update timestamps but won't destroy content. Use overwrite only when you want to fully reset pages to stubs.
• Directory creation: Always create missing category directories before writing pages.
• Broken wikilinks: Since pages are being created together from the same export, most links will resolve. Any node referenced in links but absent from nodes (broken in the original export) will still appear as a wikilink — it just won't have a corresponding page file, which is valid.
• Filtered exports: If the source graph.json was produced with visibility filtering (noted in graph.metadata), imported pages will only reflect the filtered set. Note this in the summary if graph.graph contains a filtered key.
