Vault Ingest

/vault-ingest [URL or file path or pasted content]

Ingest a source and rewrite the vault to integrate it.

Steps

1. Read _CLAUDE.md at vault root for folder map and conventions.

2. Acquire the source:

   • URL -> fetch and convert to text
   • File path -> read the file
   • Pasted content -> use directly
   • Save raw source with frontmatter:

     ---
     date: YYYY-MM-DD
     tags: [research, ingested]
     source: [URL or path]
     content_hash: [first 8 chars of sha256]
     status: ingested
     ---
     

3. Extract entities from the source:

   • Concepts, frameworks, mental models
   • Factual claims that could update or contradict existing notes
   • People, tools, libraries
   • Decisions, opinions, data points

4. Map entities to vault -- spawn parallel search agents: For each entity, search the vault:

   • Does a note about this already exist?
   • Does the source agree with, update, or contradict what the vault says?

5. Classify each entity's action:

   Situation	Action
   New concept, no vault match	Create note
   Existing note, source adds info	Append new section
   Existing note, source contradicts	Mark contradiction with callout, cite both
   Existing note, source is newer	Update claim, move old to "Historical" section
   Concept in 3+ notes	Consider vault-graduate

6. Execute rewrites -- spawn parallel write agents by folder, each must:

   • Read the target note FIRST
   • Find the right section (don't append at bottom blindly)
   • Preserve existing content, weave in new
   • Add source attribution

7. Create synthesis page if the source bridges 2+ existing domains.

8. Update: daily note, index.md, log.md

9. Report:

   ## Ingestion Report: [source title]
   
   **Raw saved:** [[raw/source-name]]
   **Notes created:** [list]
   **Notes updated:** [list + what changed]
   **Contradictions found:** [list with both sides]
   **Synthesis pages:** [list]
   
   Total vault impact: [N] files touched
   

Rules

• All output in the user's language (from _CLAUDE.md Language section). Translate ALL report headings: "## 摄入报告：", "已创建：", "已更新：", "发现矛盾：" for Chinese users. When ingesting content in a different language than the vault, translate key concepts while preserving original terms in parentheses. When updating existing notes, match that note's language.
• Rewrite, don't just add -- integration, not accumulation
• Never delete silently -- contradictions show both versions with dates
• Raw sources are immutable -- edits happen in derived notes
• content_hash for drift detection -- re-ingest detects if source changed
• Attribution mandatory -- every claim cites its source
• Search before create -- no duplicate notes

When to Suggest

• User shares a URL or paper
• User pastes a long block of content
• After research returns results worth persisting
