Second Brain — Ingest

Process raw source documents into structured, interlinked wiki pages.

Identify Sources to Process

Determine which files need ingestion:

If the user specifies a file or files, use those
If the user says "process new sources" or similar, detect unprocessed files:
- List all files in raw/ (excluding raw/assets/)
- Read wiki/log.md and extract all previously ingested source filenames from ingest entries
- Any file in raw/ not listed in the log is unprocessed
If no unprocessed files are found, tell the user

Process Each Source

For each source file, follow this workflow:

1. Read the source completely

Read the entire file. If the file contains image references, note them — read the images separately if they contain important information.

2. Discuss key takeaways with the user

Before writing anything, share the 3-5 most important takeaways from the source. Ask the user if they want to emphasize any particular aspects or skip any topics. Wait for confirmation before proceeding.

3. Create source summary page

Create a new file in wiki/sources/ named after the source (slugified). Include:

---
tags: [relevant, tags]
sources: [original-filename.md]
created: YYYY-MM-DD
updated: YYYY-MM-DD
---
