# Knowledge Compiler

Build and maintain a personal knowledge base in Obsidian vault.

## Knowledge Base location

```
~/Documents/Obsidian Vault/07 - Knowledge Base 🧠/
├── _index.md          ← Master index (auto-generated)
├── _daily-log.md      ← What changed today
├── people/            ← One article per person you follow
├── concepts/          ← One article per topic/concept
├── raw/               ← Raw collected data by platform
└── output/            ← Your queries, reports, analysis
```

## When to use

### Collect + compile (full pipeline)

User says: "collect knowledge", "compile wiki", "cập nhật knowledge base", "thu thập kiến thức"

Run:
```bash
bun run ~/hidrix-tools/scripts/compile.ts
```

This does: collect from follow list → save to SQLite → compile wiki articles → update Obsidian.

### Collect only (one person)

User says: "collect @karpathy", "thu thập bài mới của @bcherny"

Run:
```bash
bun run ~/hidrix-tools/scripts/compile.ts --user @USERNAME
```

### Research a topic and save to wiki

User says: "research topic X và lưu vào wiki", "tìm hiểu về MCP protocol"

Steps:
1. Use hidrix tools to search: `hidrix_x_search`, `hidrix_reddit_search`, `hidrix_web_search`
2. Deep read best results: `hidrix_x_thread_reader`, `hidrix_reddit_thread_reader`, `hidrix_web_fetch`
3. Write a concept article and save to Obsidian:

```bash
cat > ~/Documents/Obsidian\ Vault/07\ -\ Knowledge\ Base\ 🧠/concepts/CONCEPT-NAME.md << 'EOF'
# Concept Name

> Summary in 2-3 sentences

## Key Points

- Point 1
- Point 2

## Sources

- [Source 1](url)
- [Source 2](url)

## Related

- [[other-concept]]
- [[person-name]]

---
Last updated: YYYY-MM-DD
EOF
```

### Save a single piece of content to wiki

User says: "lưu thread này vào wiki", "save this to knowledge base"

Steps:
1. Read the content (thread, article, video transcript)
2. Summarize key points
3. Save to appropriate location:
   - About a person → `people/username.md` (append, don't overwrite)
   - About a concept → `concepts/concept-name.md`
   - Raw data → `raw/platform/date-title.md`
   - Analysis/query result → `output/query-title.md`

### Read from wiki to answer questions

User says: "Karpathy nói gì về knowledge base?", "what does @bcherny think about claude code?"

Steps:
1. Read the person's article: `read ~/Documents/Obsidian\ Vault/07\ -\ Knowledge\ Base\ 🧠/people/karpathy.md`
2. Read related concepts: `read ~/Documents/Obsidian\ Vault/07\ -\ Knowledge\ Base\ 🧠/concepts/llm-knowledge-base.md`
3. If not enough info, search for more and collect
4. Answer from wiki data + new findings
5. Save useful findings back to wiki (append to articles)

### Weekly review

User says: "weekly review", "tuần này có gì mới?", "tóm tắt tuần"

Steps:
1. Read `_daily-log.md` for this week's entries
2. Read `_index.md` for overview
3. Summarize: new people, new concepts, top posts, trends
4. Save summary to `output/weekly-YYYY-WNN.md`

## Important rules

- **Never delete** existing wiki content — only append or create new
- **concepts/ articles**: don't overwrite if exists — user may have edited manually
- **people/ articles**: can be regenerated by compile script
- **_index.md and _daily-log.md**: auto-generated by compile script, don't edit
- Always use `[[backlinks]]` to connect articles: `[[karpathy]]`, `[[vibe-coding]]`
- Filenames: lowercase, hyphens, no spaces: `llm-knowledge-base.md`
- Dates: YYYY-MM-DD format

## Follow list

The follow list is at `~/.hidrix-tools/follows.json`. To add/remove:

```bash
bun run ~/hidrix-tools/scripts/follow.ts add x @username --topics "topic1,topic2"
bun run ~/hidrix-tools/scripts/follow.ts remove x @username
bun run ~/hidrix-tools/scripts/follow.ts list
```

Or user says: "follow @username" → use the follow-manager skill.
