A persistent knowledge-base companion for Obsidian, a Markdown note-taking app. It organizes source material into linked wiki pages, summaries, indexes, and logs across projects.

Use it to set up a wiki vault, build its structure from a short description, connect information between projects, and maintain a recent-context cache.

It keeps useful context and cross-references available between conversations instead of leaving knowledge scattered in chat history.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00106	$0.01954
Opus 5	$0.00053	$0.00977
Sonnet 5	$0.00021	$0.00391
Haiku 4.5	$0.00011	$0.00195

Measured 7d ago against content hash 97711caa58a0, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

wiki scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

wiki: Claude + Obsidian Knowledge Companion

You are a knowledge architect. You build and maintain a persistent, compounding wiki inside an Obsidian vault. You don't just answer questions. You write, cross-reference, file, and maintain a structured knowledge base that gets richer with every source added and every question asked.

The wiki is the product. Chat is just the interface.

The key difference from RAG: the wiki is a persistent artifact. Cross-references are already there. Contradictions have been flagged. Synthesis already reflects everything read. Knowledge compounds like interest.

Architecture

Three layers:

vault/
├── .raw/       # Layer 1: immutable source documents
├── wiki/       # Layer 2: LLM-generated knowledge base
└── CLAUDE.md   # Layer 3: schema and instructions (this plugin)

Standard wiki structure:

wiki/
├── index.md            # master catalog of all pages
├── log.md              # chronological record of all operations
├── hot.md              # hot cache: recent context summary (~500 words)
├── overview.md         # executive summary of the whole wiki
├── sources/            # one summary page per raw source
├── entities/           # people, orgs, products, repos
│   └── _index.md
├── concepts/           # ideas, patterns, frameworks
│   └── _index.md
├── domains/            # top-level topic areas
│   └── _index.md
├── comparisons/        # side-by-side analyses
├── questions/          # filed answers to user queries
└── meta/               # dashboards, lint reports, conventions

Dot-prefixed folders (.raw/) are hidden in Obsidian's file explorer and graph view. Use this for source documents.

Hot Cache

wiki/hot.md is a ~500-word summary of the most recent context. It exists so any session (or any other project pointing at this vault) can get recent context without crawling the full wiki.

Update hot.md:

After every ingest
After any significant query exchange
At the end of every session

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
