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
---

# Source Title

**Source:** original-filename.md
**Date ingested:** YYYY-MM-DD
**Type:** article | paper | transcript | notes | etc.

## Summary

Structured summary of the source content.

## Key Claims

- Claim 1
- Claim 2
- ...

## Entities Mentioned

- [[Entity Name]] — brief context
- ...

## Concepts Covered

- [[Concept Name]] — brief context
- ...

4. Update entity and concept pages

For each entity (person, organization, product, tool) and concept (idea, framework, theory, pattern) mentioned in the source:

If a wiki page already exists:

Read the existing page
Add new information from this source
Add the source to the
```
sources:
```
frontmatter list
Update the
```
updated:
```
date
Note any contradictions with existing content, citing both sources

If no wiki page exists:

Create a new page in the appropriate subdirectory:
- ```
wiki/entities/
```
  for people, organizations, products, tools
- ```
wiki/concepts/
```
  for ideas, frameworks, theories, patterns
Include YAML frontmatter with tags, sources, created, and updated fields
Write a focused summary based on what this source says about the topic

5. Add wikilinks

Ensure all related pages link to each other using

[[wikilink]]

syntax. Every mention of an entity or concept that has its own page should be linked.

6. Update wiki/index.md

For each new page created, add an entry under the appropriate category header:

- [[Page Name]] — one-line summary (under 120 characters)

7. Update wiki/log.md

Append:

## [YYYY-MM-DD] ingest | Source Title
Processed source-filename.md. Created N new pages, updated M existing pages.
New entities: [[Entity1]], [[Entity2]]. New concepts: [[Concept1]].

8. Report results

Tell the user what was done:

Pages created (with links)
Pages updated (with what changed)
New entities and concepts identified
Any contradictions found with existing content

Conventions

Source summary pages are factual only. Save interpretation and synthesis for concept and synthesis pages.
A single source typically touches 10-15 wiki pages. This is normal and expected.
When new information contradicts existing wiki content, update the wiki page and note the contradiction with both sources cited.
Prefer updating existing pages over creating new ones. Only create a new page when the topic is distinct enough to warrant its own page.
Use
```
[[wikilinks]]
```
for all internal references. Never use raw file paths.
