openkb skillB
openkb is agent-read markdown (skill) from yuezhiai/jonex: Use when the user asks about content in their OpenKB knowledge base — research topics, concepts compiled from their documents, cross-document synthesis — or mentions `openkb`, an `.openkb/` directory, or a `wiki/` tree generated by openkb. The user may invoke you from any working directory; the active KB resolves via `openkb status`. Do NOT use for arbitrary Markdown directories, Obsidian vaults, or documentation sites not built by openkb..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# OpenKB knowledge base
The user has compiled their documents into a Markdown wiki at `wiki/`.
The wiki holds these kinds of pages:
- **Concept pages** at `wiki/concepts/*.md` — cross-document synthesis
on specific topics. This is where OpenKB's value compounds: a
concept with multiple sources represents knowledge merged across
documents the user has ingested.
- **Entity pages** at `wiki/entities/*.md` — one per specific named
thing (people, organizations, places, products, named works,
events), accumulated across documents. Each has a `type:`
frontmatter field. For "who is X" / "what is X" questions about a
named thing, read the matching `entities/` page first.
- **Summary pages** at `wiki/summaries/*.md` — one per ingested
document, linking to the concepts that document touches.
- **Source files** at `wiki/sources/*.{md,json}` — full text for short
docs (`.md`) or a paginated content array for long PDFs (`.json`).
## First: find where the KB lives
The user may invoke you from anywhere — the active knowledge base is
not necessarily in your current working directory. Run `openkb status`
to discover the KB root and a summary in one call:
```
$ openkb status
…Read the whole file at its exact version.
How to install
mdr add yuezhiai/jonex/openkb@git:20260812.f6205dcmdr add yuezhiai/jonex/openkb@sha256:f07c92afb29c6568Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
