Add LLM Wiki Agent — persistent LLM-maintained knowledge base

Replaces dual-agent demo with a full personal knowledge base system
where Claude reads source documents and incrementally builds and
maintains a structured, interlinked wiki of markdown pages.

- tools/ingest.py: reads a source, extracts knowledge, updates wiki pages
- tools/query.py: queries the wiki with Claude, optionally files answers back
- tools/lint.py: health-checks the wiki (orphans, contradictions, gaps)
- tools/build_graph.py: two-pass graph builder (wikilinks + Claude inference)
  with Louvain community detection and vis.js interactive HTML output
- CLAUDE.md: schema and workflow instructions for the LLM
- wiki/: starter index, log, and overview pages
- raw/, graph/: directory scaffolding

# LLM Wiki Agent — Schema & Workflow Instructions
This document defines how Claude maintains this wiki. Follow these conventions exactly in every session.
## Directory Layout
```
raw/ # Immutable source documents — never modify these
wiki/ # Claude owns this layer entirely
index.md # Catalog of all pages — update on every ingest
log.md # Append-only chronological record
overview.md # Living synthesis across all sources
sources/ # One summary page per source document
entities/ # People, companies, projects, products
concepts/ # Ideas, frameworks, methods, theories
graph/ # Auto-generated graph data — regenerate with build_graph.py
tools/ # CLI scripts
```
## Page Format
Every wiki page uses this frontmatter:
```yaml
---
title: "Page Title"
type: source | entity | concept | synthesis
tags: []
sources: [] # list of source slugs that inform this page
last_updated: YYYY-MM-DD
---
```
Use `[[PageName]]` wikilinks to link to other wiki pages. These are parsed by build_graph.py.
---
## Ingest Workflow
Triggered when user runs: `python tools/ingest.py <source-path>`
Steps (in order):
1. Read the source document fully
2. Write `wiki/sources/<slug>.md` — title, date, key claims, key quotes, tags, links to entity/concept pages
3. Update `wiki/index.md` — add entry under the correct section
4. Update `wiki/overview.md` — revise synthesis if the source adds new perspectives, themes, or contradicts prior conclusions
5. Update existing entity pages that this source mentions; create new entity pages if needed
6. Update existing concept pages that this source discusses; create new concept pages if needed
7. Flag any contradictions with existing wiki content in the log entry
8. Append to `wiki/log.md` with this prefix format: `## [YYYY-MM-DD] ingest | <Title>`
### Source Page Format
```markdown
---
title: "Source Title"
type: source
tags: []
date: YYYY-MM-DD
source_file: raw/...
---
## Summary
24 sentence summary.
## Key Claims
- Claim 1
- Claim 2
## Key Quotes
> "Quote here" — context
## Connections
- [[EntityName]] — how they relate
- [[ConceptName]] — how it connects
## Contradictions
- Contradicts [[OtherPage]] on: ...
```
---
## Query Workflow
Triggered when user runs: `python tools/query.py "<question>"`
Steps:
1. Read `wiki/index.md` to identify relevant pages
2. Read the relevant pages
3. Synthesize an answer with inline citations as wikilinks: `[[PageName]]`
4. Ask the user if they want the answer filed as a new synthesis page in `wiki/`
---
## Lint Workflow
Triggered when user runs: `python tools/lint.py`
Check for:
- **Orphan pages** — wiki pages with no inbound `[[links]]` from other pages
- **Contradictions** — claims that conflict across pages
- **Stale summaries** — pages not updated after newer sources changed the picture
- **Missing entity pages** — entities mentioned in 3+ pages but lacking their own page
- **Broken links** — `[[WikiLinks]]` pointing to pages that don't exist
- **Data gaps** — important questions the wiki cannot answer — suggest new sources to find
Output a lint report as markdown.
---
## Graph Workflow
Triggered when user runs: `python tools/build_graph.py`
- Pass 1: Parse all `[[wikilinks]]` in wiki pages → deterministic edges tagged `EXTRACTED`
- Pass 2: Call Claude API to infer implicit relationships not captured by wikilinks → edges tagged `INFERRED` with confidence score
- Tag ambiguous relationships as `AMBIGUOUS`
- Use Louvain community detection to cluster nodes
- Output `graph/graph.json` and `graph/graph.html`
- Cache by SHA256 of page content — only reprocess changed pages
---
## Naming Conventions
- Source slugs: `kebab-case` matching the source filename
- Entity pages: `TitleCase.md` (e.g. `OpenAI.md`, `SamAltman.md`)
- Concept pages: `TitleCase.md` (e.g. `ReinforcementLearning.md`, `RAG.md`)
- Source pages: `kebab-case.md`
## Index Format
```markdown
# Wiki Index
## Overview
- [Overview](overview.md) — living synthesis
## Sources
- [Source Title](sources/slug.md) — one-line summary
## Entities
- [Entity Name](entities/EntityName.md) — one-line description
## Concepts
- [Concept Name](concepts/ConceptName.md) — one-line description
## Syntheses
- [Analysis Title](syntheses/slug.md) — what question it answers
```
## Log Format
Each entry starts with `## [YYYY-MM-DD] <operation> | <title>` so it's parseable:
```
grep "^## \[" wiki/log.md | tail -10
```
Operations: `ingest`, `query`, `lint`, `graph`
