name	wiki-sync
description	Synthesize a single source note into the vault's wiki/ folder — read the source, find or create the right wiki entry, write it back with proper frontmatter and source links. Used by Lumina's background wiki manager when a note changes. Use when this capability is needed.

Wiki synthesis playbook

Lumina maintains a wiki/ folder inside each vault that distills the user's source notes into a navigable knowledge layer. When this skill is invoked you are told the path of one source note that just changed, and your job is to update wiki/ accordingly.

Steps

1. Read the source note. Use the read tool on the relative path you were given. Distill the key claims, definitions, and references worth surfacing — not a full copy of the note.

2. Survey existing wiki entries. Use list on wiki/ to see what's already there. Use glob (wiki/**/*.md) and grep (relevant terms) to find entries that overlap with the source note's topics. Prefer extending an existing entry over creating a new one — duplication makes the wiki worse, not better.

3. Decide write strategy:

   • Update existing entry: use edit for surgical changes when the entry exists and the source adds incremental information.
   • Create new entry: use write only when the topic genuinely has no home yet. Path: wiki/<topic-slug>.md.

4. Wiki file format. Every wiki entry must have:

   • YAML frontmatter:

     ---
     title: <Human-readable title>
     source_paths: [<rel/path/to/source.md>, ...]
     updated_at: <ISO 8601 timestamp>
     ---
     

   • When you extend an existing entry, append the source path to source_paths and update updated_at. Don't overwrite.
   • Body: concise prose. The wiki is a synthesis layer, not a copy. Cite source notes inline using [[wiki link]] syntax referring to the source's relative path or title.

5. Done signal. When you're finished, respond with one paragraph summarising what you changed (which wiki files updated, which created). Do not call more tools after this summary.

Constraints

• Do not run shell commands. Wiki sync runs in the background and shell access is not available.
• Stay inside the vault. Read and write paths are confined to the vault root by the agent's permission policy — going outside will fail.
• Do not delete user source notes. You may delete obsolete wiki entries you previously created (i.e., entries whose source_paths all point at removed notes).
• Stub instead of fabricate. If the source note is empty or trivially short, write a brief stub (1–2 sentences) instead of inventing content.
• Don't add empty wiki entries. If the source has nothing worth synthesising, just say so in your summary and skip the write.

Common pitfalls

• Creating a new wiki entry when one already exists. Always grep first.
• Copying source content verbatim. The wiki should distill, not mirror.
• Forgetting to update updated_at. This breaks the wiki's freshness signals.
• Using shell to find files. Use glob and grep. Shell isn't registered for this agent.
