| description | This skill should be used when the user says "build a wiki", "maintain a wiki", "ingest docs into wiki", "query my wiki", "set up llm wiki", "wiki-based knowledge base", "stop re-reading docs every session", "persistent knowledge base", or "compress my docs into wiki pages". |

LLM Wiki
Build and maintain a persistent wiki Claude can reference instead of re-ingesting raw documents each session. Derived from Karpathy's LLM Wiki pattern.
Why it works: Raw docs reloaded every session = wasted tokens. A wiki is a distilled, pre-summarized artifact — same knowledge, 10x lower token cost.
Architecture
raw-sources/ (immutable originals)
└── docs, PDFs, changelogs, README files
wiki/ (LLM-maintained markdown pages)
├── index.md ← content catalog
├── log.md ← append-only ingest/query log
└── [topic].md ← one page per concept
CLAUDE.md (tells Claude: "reference wiki/ instead of raw-sources/")
Setup
Create wiki directory at project root or ~/.claude/wiki/ for global:
mkdir -p wiki
echo "# Wiki Index\n\n## Pages\n" > wiki/index.md
echo "# Ingest Log\n" > wiki/log.md
Add to CLAUDE.md:
## Knowledge Base
Wiki at `wiki/`. Reference wiki pages instead of raw source files.
Do not re-read raw docs unless wiki page is missing or stale.
Operations
Ingest: Add New Source to Wiki
When user provides a doc, URL, or file to ingest:
- Read the source
- Identify 3-5 key concepts worth persisting
- Create or update
wiki/[topic].md per concept (one page per topic)
- Update
wiki/index.md with new pages
- Append to
wiki/log.md: [DATE] INGEST: [source] → [pages updated]
Per wiki page format:
# [Topic]
_Last updated: [DATE] | Source: [origin]_
## Summary
[2-3 sentence distillation]
## Key Points
- [point 1]
- [point 2]
## Related
- [[other-wiki-page]]
Query: Answer from Wiki
When user asks a question:
- Search
wiki/index.md for relevant pages
- Read matching wiki pages
- Synthesize answer with citations:
(wiki/[page].md)
- If the answer reveals new insight worth keeping, create a new wiki page for it
- Append to
wiki/log.md: [DATE] QUERY: [question] → [pages used]
Lint: Health Check
Periodically check wiki integrity:
Contradictions: pages with conflicting claims
Stale pages: last updated > 90 days AND source has changed
Orphaned pages: not referenced in index.md
Missing links: [[references]] with no matching file

Token Savings Estimate
| Approach | Tokens per session |
|---|
| Re-read raw 50-page doc | ~15,000 tokens |
| Reference 3 wiki pages | ~600 tokens |
| Savings | ~96% |
Integration with context_forge
- Run
/estimate-tokens after wiki setup to measure baseline
- Add
wiki/ reference to CLAUDE.md using /optimize-claudemd
- Session-start hook warns if raw docs loaded but wiki exists
